There is a growing interest in the formulations of coating chemical fertilizers with both UI and NI. However, limited information is available on the combined use of UI and NI applied with urea fertilizer. Therefore the aim of this study was to investigate the effects of treating urea with both UI and NI to minimize NH3 volatilization. Two experiments were set up in volatilization chambers under controlled conditions to examine this process. In the first experiment, UR was treated with the urease inhibitor NBPT [N-(n-butyl) thiophosphoric acid triamide] at a rate of 1060\u00a0mg\u00a0kg\u22121 urea and/or with the nitrification inhibitor DCD (dicyandiamide) at rates equivalent to 5 or 10% of the urea N. A randomized experimental design with five treatments and five replicates was used: 1) UR, 2) UR\u00a0+\u00a0NBPT, 3) UR\u00a0+\u00a0DCD 10%, 4) UR\u00a0+\u00a0NBPT\u00a0+\u00a0DCD 5%, and 5) UR\u00a0+\u00a0NBPT\u00a0+\u00a0DCD 10%. The fertilizer treatments were applied to the surface of an acidic Red Latosol soil moistened to 60% of the maximum water retention and placed inside volatilization chambers. Controls chambers were added to allow for NH3 volatilized from unfertilized soil or contained in the air that swept over the soil surface. The second experiment had an additional treatment with surface-applied DCD. The chambers were glass vessels (1.5\u00a0L) fit with air inlet and outlet tubings to allow air to pass over the soil. Ammonia volatilized was swept and carried to a flask containing a boric acid solution to trap the gas and then measured daily by titration with a standardized H2SO4 solution. Continuous measurements were recorded for 19 and 23 days for the first and second experiment, respectively. The soil samples were then analyzed for UR\u2013,       NH   4  +   \u2013    , and       NO   3  \u2212   \u2013  N    . Losses of NH3 by volatilization with unamended UR ranged from 28 to 37% of the applied N, with peak of losses observed the third day after fertilization. NBPT delayed the peak of NH3 losses due to urease inhibition and reduced NH3 volatilization between 54 and 78% when compared with untreated UR. Up to 10 days after the fertilizer application, NH3 losses had not been affected by DCD in the UR or the UR\u00a0+\u00a0NBPT treatments; thereafter, NH3 volatilization tended to decrease, but not when DCD was present. As a consequence, the addition of DCD caused a 5\u201316% increase in NH3 volatilization losses of the fertilizer N applied as UR from both the UR and the UR\u00a0+\u00a0NBPT treatments. Because the effectiveness of NBPT to inhibit soil urease activity was strong only in the first week, it could be concluded that DCD did not affect the action of NBPT but rather, enhanced volatilization losses by maintaining higher soil       NH   4  +      concentration and pH for a longer time. Depending on the combination of factors influencing NH3 volatilization, DCD could even offset the beneficial effect of NBPT in reducing NH3 volatilization losses.", "keywords": ["soil chemistry", "Urease inhibitors", "Surface treatment", "nutrient use efficiency", "Ammonia volatilization", "01 natural sciences", "630", "Ammonia", "Oxidation", "DCD", "Urea", "Urea fertilizers", "Fertilizers", "volatilization", "Groundwater", "0105 earth and related environmental sciences", "soil surface", "coating", "fertilizer application", "Urease inhibitor", "04 agricultural and veterinary sciences", "Nitrification inhibitor", "Nitrification", "Inorganic acids", "6.

This requires a better understanding of the synergies and trade-offs of agronomic management while accounting for the controlling effects of site-specific factors (covariates). We systematically evaluated 113 meta-analytical studies assessing impacts of crop management measures (rotation, cover cropping, residue retention), soil and water measures (irrigation, tillage), soil amendments (enhanced efficiency, biochar), fertilizer use (organic, mineral, combined organic-mineral) and \u201c4R'\u201d fertilizer strategies (right source, rate, timing, placement) on sustainability indicators. These indicators include crop yield, crop N and P (content, uptake, and use efficiency), soil quality indicators (soil organic C, N and P contents, compaction), soil emissions of ammonia (NH3) and greenhouse gases (CO2, N2O), and nutrient losses to water (N and P surplus or leaching). Nutrient management, including 4R practices as well as enhanced efficiency amendments, had the largest impact, increasing crop yields and N uptake while reducing N2O and NH3 emissions as well as N surplus, whereas effects on CO2 emissions were variable. Although all measures positively impacted soil C, the largest effect was due to biochar, followed by organic fertilizer input. Biochar positively impacted crop yield, diminished N2O and NH3 emissions as well as N surplus, and increased CO2 emissions. Within crop management, only cover cropping had a significant positive effect on crop yield, while both cover crops and rotation slightly enhanced N uptake and the sequestration of C and N in soil, thus reducing N2O emissions and N surplus. Minimal tillage practices generally increased SOC, while results for crop yield, N surplus and N2O emissions were variable. Site-specific factors had substantial impacts on the evaluated impacts of measures, most importantly climate, crop type, soil texture, soil pH, soil organic C, N dose, and experimental duration. Considering the variation among meta-analytical protocols followed, we recommend that field studies and meta-analytical work adhere to harmonized guidelines with respect to the reporting of site-level data, experimental design, and the statistical procedures used. This will ensure data comparability between studies, improve the quality of meta-analysis results, and give better insights into currently uncertain or unknown impacts of agronomic measures.", "keywords": ["0301 basic medicine", "2.

However, in many places its intensive use has become a burden to the environment, and legislation has been introduced to restrict nutrient applications. In combination with changing production scenarios as a result of climate change, this means an improved understanding is needed of how low nutrient availability and climatic stress factors affect yields and yield stability.We examined the long-term effects mineral and organic fertilisation on a nutrient-depleted field, and observed large annual variations: depending on the year, average spring barley yields under unfertilised management (U) were between 17-75% lower than the reference N1/2P1/2K1/2 (60-10-60 kg ha(-1)). Yields increased up to 174% under N1P1K1 (120-20-120 kg ha(-1)), while animal manure applications at an N availability level corresponding to N-1 were between 79 and 137%. No temporal yield trends could be observed, but long-term changes of Olsen-P and exchangeable K were related to the nutrient balances (inputs-offtake) (r(2) = 0.60 and 0.59, respectively, P < 0.001).Multiple linear regression analysis was used to examine the effects of the treatments in combination with annual weather variations. The results could be split into two outcomes, 1) a general relation between yields and temperatures for the periods of early spring (P < 0.01, multiple R-2 = 0.31) and summer (P < 0.001, multiple R-2 =0.45), and 2) an interaction between temperature and nutrient applications during crop establishment, leading to a diverse response of relative yields (P < 0.001 multiple R-2 =0.64), i.e. relative yield losses under the unfertilised treatment (U) were greater in years with lower spring temperatures, and, conversely, the increased nutrient availability in the fully mineral and organically fertilised treatments could partially alleviate the negative effects.After 13 years of repeated fertilisation, inputs were suspended for a single year and only N was applied to evaluate the residual effects. Yields were significantly affected by the different fertilisation histories (P < 0.001). Likewise, apparent nitrogen recovery tended to improve with previous inputs, but the observations were highly variable.Overall, the analyses agree with the notion that brief periods of stress at a critical stage may significantly affect yields, and confirmed that management of sufficient nutrient availability is critical for maintaining high and stable yields.

A stocktake study of current methods of delivering fertilisation advice took place across 23 European countries. The stocktake was in the form of a questionnaire, comprising 46 questions. Information was gathered on a large range of factors, including soil analysis methods, along with soil, crop and climatic factors taken into consideration within fertilisation calculations. The questionnaire was completed by experts, who are involved in compiling fertilisation recommendations within their country. Substantial differences exist in the content, format and delivery of fertilisation guidelines across Europe. The barriers, constraints and potential benefits of a harmonised approach to fertilisation across Europe are discussed. The general consensus from all participating countries was that harmonisation of fertilisation guidelines should be increased, but it was unclear in what format this could be achieved. Shared learning in the delivery and format of fertilisation guidelines and mechanisms to adhere to environmental legislation were viewed as being beneficial. However, it would be very difficult, if not impossible, to harmonise all soil test data and fertilisation methodologies at EU level due to diverse soil types and agro\uffe2\uff80\uff90ecosystem influences. Nevertheless, increased future collaboration, especially between neighbouring countries within the same environmental zone, was seen as potentially very beneficial. This study is unique in providing current detail on fertilisation practices across European countries in a side\uffe2\uff80\uff90by\uffe2\uff80\uff90side comparison.

Vermicompost (VC), a <sup>15</sup>N-labeled N solution  (N<sub>sol</sub>) and a <sup>33</sup>P-labeled P  solution (P<sub>sol</sub>) were used to fertilize the soil and  create the different treatments. A commercial vermicompost of bovine  manure produced in Northwestern Italy was used in this study (Fig. S1).  The commercial vermicompost was air-dried and milled to &lt;2 mm. The  vermicompost was characterized using the official methods of the  Regione-Piemonte (1998). The residual humidity content of the dry  vermicompost was 432 g kg<sup>-1</sup>, the pH in a water  suspension (1:10) was 9.9, the C<sub>org</sub> value in dry  matter was 198 g kg<sup>-1</sup> DM , the total P was 9 g  kg<sup>-1</sup> DM , and the total N was 14.8 g  kg<sup>-1</sup> DM. Ammonium sulfate  ((NH<sub>4</sub>)<sub>2</sub>SO<sub>4</sub>) and potassium phosphate (KH<sub>2</sub>PO<sub>4</sub>) were used to prepare separate aqueous solution of 80.3 \u00b5g N ml<sup>-1</sup> and 28.5 \u00b5g P ml<sup>-1</sup>, respectively.

Although creating a granular or pelletized OMF would have been ideal for testing potential physical interactions between vermicompost and the mineral fertilizers, this effect was not addressed in this research because of the difficulties in producing and OMF labelled with a radioisotope P tracer.

The soil was sieved to 5 mm and air-dried for approximately four months prior to the start of the experiment. The soil chemical characteristics measured before the beginning of the experiment indicated a low content in both plant-available N and P. Before starting the pot experiment, the bulk soil was fertilized with nutrient solutions adding 300 mg K, 60 mg Ca, 50 mg Mg, 1 mg Zn, 0.1 mg Mo, 1 mg Fe, 1 mg B, 2 mg Mn, 2 mg Cu and 0.1 mg Co per kg<sup>-1</sup> soil to avoid any possible complementary nutrient deficiency. After fertilization, the soil was humidified to 45 % of its water holding capacity (corresponding to 109 g per kg of dry soil) and pre-incubated during 10 days at 22 \u00b0C to boost soil microbial activity. After pre-incubation, the pots were filled with the equivalent of 1 kg of air-dried soil and fertilized according to treatments. For the fertilization, two holes of 2 cm of depth and 0.5 cm of diameter were made in each pot, and on day 0, each of them was fertilized. Immediately after fertilization, 0.75 g seeds of Italian ryegrass (<em>Lolium multiflorum </em>var. Gemini) were distributed uniformly over the soil and then covered with 100 g of pure sand. The pots were kept in a greenhouse at 24 and 20 \u00b0C, with 12 hours light, and 65% air humidity. Soils were irrigated daily based on weight loss. To satisfy the crop requirements, irrigation was increased to keep 60 % of field capacity during the first 2 weeks, and then up to 70 % of field capacity until the final harvest. The first harvest was made 4 weeks (Fig. S3) after sowing and a second harvest was made after 4 further weeks. The harvest consisted in cutting the whole biomass at approximately 1 cm above the soil surface. Each treatment had 4 replicates. Pots were completely randomized three times per week. Incubation Experiment Setup An incubation experiment was performed to assess the influence of the vermicompost on the nutrient availability and flow from the mineral fertilizers in the soil. Soil fertilizers used were the same as in the pot experiment, but no plants were sown. The treatments for the incubation were MF<sub>NP</sub>, OMF<sub>7.5C</sub> and OMF<sub>15C</sub>. The incubation set-up and soil sampling was adapted from Sica et al. (2023), and consisted in using plastic cylinders of 18 mm of height and 60 mm of diameter. Each experimental unit had two cylinders placed one above the another and was filled with 148.6 g of soil in total. The two cylinders were separated by a nylon net with 45 \u00b5m mesh size that allowed soil solution flow. The top cylinder was fertilized replicating vermicompost, N<sub>sol</sub>, and P<sub>sol</sub> quantities and procedures as for one hole of the pot experiment. On the day of the P<sub>min</sub> fertilization, the P<sub>sol</sub> had a specific activity of 3.5 kBq mg<sup>-1</sup> P.\u00a0 With the P<sub>min</sub> fertilization, soils from the incubation experiment received an activity of 313.5 Bq g<sup>-1</sup> soil.\u00a0 The soil in cylinders was humidified to 70 % of field capacity. Experimental units were placed in a box covered with a plastic sheet that did not allow vapor and light flows and kept at the same temperature conditions as the pot experiment for 10 days. Each treatment had 6 experimental units and they were completely randomized. After the incubation, the soil from the top cylinder (topsoil) was collected entirely, while from the bottom cylinder additional soil was collected from the mesh to 6 mm depth (bottom soil). Soil from two randomly chosen experimental units was mixed to reach a higher amount of sample to be analyzed, thus leaving a total of 3 replicates per treatment. Measurements on Plants In the pot experiment, at each harvest, Italian ryegrass shoot biomass was cut and dried at 40 \u00b0C for 72 hours, and then weighted to calculate dry matter yield. Afterwards, all shoot biomass was milled in a rotational miller and stored until analysis. A chemical element analyzer (Vario Pyro cube, Elementar, Germany), coupled to a mass spectrometer (IsoPrime100 IRMS, Isoprime, United Kingdom) was used to analyze total C, total N and <sup>15</sup>N/<sup>14</sup>N from shoot biomass. For determination of P concentrations in shoot tissues, 0.25 g of milled ryegrass shoot biomass were ashed at 450 \u00b0C during 100 min. Subsequently, ashes were dissolved in 3 ml of 15.6 M nitric acid and then the volume was brought up to 25 ml with Milli-Q water. Total P concentration in the extracts was analyzed by colorimetry with malachite green (Ohno &amp; Zibilske, 1991). The <sup>33</sup>P radioactivity in biomass was determined using a liquid scintillation counter (TRI CARB 2500 TR, Packard) by mixing 2 ml of extract or solution with 5 ml of a scintillation liquid (Ultima Gold AB, Packard). Values were corrected for quenching and for radioactive decay back to the day of pot fertilization. Measurements on Soil Soil samples of the incubation experiment were dried at 40\u00b0C for 3 days and then ball-milled and stored until analysis. Soil samples were analyzed for concentration of total N and <sup>15</sup>N/<sup>14</sup>N ratio with the same method and instruments as for plant samples. The <sup>15</sup>N enrichment of total soil N was then related to the <sup>15</sup>N enrichment of the fertilizer and decreasing <sup>15</sup>N enrichment of soil N interpreted as less fertilizer N having moved in the respective soil zone/layer (Frick et al., 2022). For determining P contained in soil, soil ashes were obtained similarly to plant biomass ashes. Soil ashes were dissolved into 50 ml of H<sub>2</sub>SO<sub>4</sub> solution (0.5 M). Then, 5 to 10 ml of the solution was filtered with 0.2 \u03bcm syringe filters and stored at 4\u00b0C for 1 day until analysis of radioactivity. Values of <sup>33</sup>P radioactivity in extracts were measured 32 days after fertilization following the same procedures as with biomass samples and corrected for radioactive decay by calculating back to day 0 of fertilization. The decrease of the specific activity of the soil P with distance from the fertilizer spot indicated decreasing presence of fertilizer P (as above explained for N). Statistical Analysis Both experiments had a completely randomized design. When testing for differences between treatments over the harvests, a repeated measures ANOVA was used. The incubation experiment was analyzed comparing treatments of each soil layer with a one-way ANOVA using treatment as factor. If significant differences between treatments were found a Tukey\u2019s HSD test was performed as a post hoc comparison. Some values were analyzed as the total production (sums or averages of both harvests, or both soil layers), in those cases data were analyzed by a one-way ANOVA using treatment as factor. All analyses were performed using the software R, version 4.0.5. Package multcompView was used to display post hoc results.", "keywords": ["vermicompost", "FOS: Agricultural sciences", "nutrient use efficiency", "double labeling", "organo-mineral fertilizer"], "contacts": [{"organization": "Sitzmann, Tomas Javier, Sica, Pietro, Zavattaro, Laura, Moretti, Barbara, Grignani, Carlo, Oberson, Astrid,", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/10.5061/dryad.ffbg79d23"}, {"rel": "self", "type": "application/geo+json", "title": "10.5061/dryad.ffbg79d23", "name": "item", "description": "10.5061/dryad.ffbg79d23", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.5061/dryad.ffbg79d23"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2023-01-18T00:00:00Z"}}, {"id": "10261/349203", "type": "Feature", "geometry": null, "properties": {"updated": "2026-05-30T16:25:51Z", "type": "Journal Article", "created": "2023-09-30", "title": "Stocktake study of current fertilisation recommendations across Europe and discussion towards a more harmonised approach", "description": "Abstract                   <p>The European Commission has set targets for a reduction in nutrient losses by at least 50% and a reduction in fertiliser use by at least 20% by 2030 while ensuring no deterioration in soil fertility. Within the mandate of the European Joint Programme EJP Soil \uffe2\uff80\uff98Towards climate\uffe2\uff80\uff90smart sustainable management of agricultural soils\uffe2\uff80\uff99, the objective of this study was to assess current fertilisation practices across Europe and discuss the potential for harmonisation of fertilisation methodologies as a strategy to reduce nutrient loss and overall fertiliser use. A stocktake study of current methods of delivering fertilisation advice took place across 23 European countries. The stocktake was in the form of a questionnaire, comprising 46 questions. Information was gathered on a large range of factors, including soil analysis methods, along with soil, crop and climatic factors taken into consideration within fertilisation calculations. The questionnaire was completed by experts, who are involved in compiling fertilisation recommendations within their country. Substantial differences exist in the content, format and delivery of fertilisation guidelines across Europe. The barriers, constraints and potential benefits of a harmonised approach to fertilisation across Europe are discussed. The general consensus from all participating countries was that harmonisation of fertilisation guidelines should be increased, but it was unclear in what format this could be achieved. Shared learning in the delivery and format of fertilisation guidelines and mechanisms to adhere to environmental legislation were viewed as being beneficial. However, it would be very difficult, if not impossible, to harmonise all soil test data and fertilisation methodologies at EU level due to diverse soil types and agro\uffe2\uff80\uff90ecosystem influences. Nevertheless, increased future collaboration, especially between neighbouring countries within the same environmental zone, was seen as potentially very beneficial. This study is unique in providing current detail on fertilisation practices across European countries in a side\uffe2\uff80\uff90by\uffe2\uff80\uff90side comparison.

This requires a better understanding of the synergies and trade-offs of agronomic management while accounting for the controlling effects of site-specific factors (covariates). We systematically evaluated 113 meta-analytical studies assessing impacts of crop management measures (rotation, cover cropping, residue retention), soil and water measures (irrigation, tillage), soil amendments (enhanced efficiency, biochar), fertilizer use (organic, mineral, combined organic-mineral) and \u201c4R'\u201d fertilizer strategies (right source, rate, timing, placement) on sustainability indicators. These indicators include crop yield, crop N and P (content, uptake, and use efficiency), soil quality indicators (soil organic C, N and P contents, compaction), soil emissions of ammonia (NH3) and greenhouse gases (CO2, N2O), and nutrient losses to water (N and P surplus or leaching). Nutrient management, including 4R practices as well as enhanced efficiency amendments, had the largest impact, increasing crop yields and N uptake while reducing N2O and NH3 emissions as well as N surplus, whereas effects on CO2 emissions were variable. Although all measures positively impacted soil C, the largest effect was due to biochar, followed by organic fertilizer input. Biochar positively impacted crop yield, diminished N2O and NH3 emissions as well as N surplus, and increased CO2 emissions. Within crop management, only cover cropping had a significant positive effect on crop yield, while both cover crops and rotation slightly enhanced N uptake and the sequestration of C and N in soil, thus reducing N2O emissions and N surplus. Minimal tillage practices generally increased SOC, while results for crop yield, N surplus and N2O emissions were variable. Site-specific factors had substantial impacts on the evaluated impacts of measures, most importantly climate, crop type, soil texture, soil pH, soil organic C, N dose, and experimental duration. Considering the variation among meta-analytical protocols followed, we recommend that field studies and meta-analytical work adhere to harmonized guidelines with respect to the reporting of site-level data, experimental design, and the statistical procedures used. This will ensure data comparability between studies, improve the quality of meta-analysis results, and give better insights into currently uncertain or unknown impacts of agronomic measures.", "keywords": ["2.

Therefore, this vegetable long-term fertilization experiment can be used to investigate different plant-soil-systems under the same climatic conditions. The experimented was halted in 2022. The experimental site (52\u00b021\u201901.30\u2019\u2019 E, 13\u00b019\u201905.47\u2019\u2019 N, 50 m a.s.l.) is located in the transition zone between the more maritime-affected Northern German Plain and the continental climate of the European mainland. Weather data were collected in an agrometeorological station close to the experimental area. The long-term means (1991-2020) for air temperature and annual precipitation are 9.7 \u00b0C and 492 mm. The single plots are quadratic concrete boxes with walls of 10 cm thickness, a surface area of 4 m2 and a depth of 75 cm. The upper 50 cm are filled with the tested soils; the lower 25 cm comprises a coarse-sandy drainage layer. The three soil types are Arenic Luvisol (weak loamy sand), Gleyic Fluvisol (heavy sandy loam) and Luvic-Phaeozem (medium clayey silt) according to the World Reference Base \u2013 WRB (and the Bodenkundliche Kartieranleitung \u2013 KA4). Within 10 rotations, the vegetable species white cabbage (Brassica oleracea L. var. capitata f. alba), carrot (Daucus carota L.), cucumber (Cucumis sativus L.), leek (Allium porrum L.) and celery (Apium graveolens L. var. rapaceum Mill.) were cultivated. No celery was cultivated during the first rotation. The experiment consists of 12 fertilization treatments in different combinations of mineral N fertilization and organic amendments and as quadruplicate for each of the three soils. The experimental set-up scheme can be found in the supplementary material. Mineral N fertilizer was applied as calcium ammonium nitrate. Mineral P and K fertilization was uniform for all treatments. Total N and total C in soil, plant and organic amendments were determined using a CNS analyser VARIO El (Elemental Hanau) since 1995 and before by wet combustion with K2Cr2O7 und H2SO4. C and N in the soil samples and N in the plant samples were analysed annually. The C contents of the crop residues (leaf + stalk + root) of the five vegetable species were investigated irregularly. In autumn, the soil was annually dug up to 20 cm by using a spade. Weeds were removed by a combination of mechanical (cultivator, rake or hoe) and chemical measures. Insect protection nets, insecticides or fungicides were used where necessary. Approximately 150 mm per year was additionally irrigated with a sprinkler system.
