In the first experiment, nine species of trees were grown in the ground in open-top chambers in central Panama at ambient and elevated CO2 (about twice ambient). On average, leaf phenolic contents were 48% higher under elevated CO2. Biomass accumulation was not affected by CO2, but starch, total non-structural carbohydrates and C/N ratios all increased. In a second experiment with Ficus, an early successional species, and Virola, a late successional species, treatments were enriched for both CO2 and nutrients. For both species, nutrient fertilization increased plant growth and decreased leaf carbohydrates, C/N ratios and phenolic contents, as predicted by the carbon/nutrient balance hypothesis. Changes in leaf C/N levels were correlated with changes in phenolic contents for Virola (r=0.95, P<0.05), but not for Ficus. Thus, elevated CO2, particularly under conditions of low soil fertility, significantly increased phenolic content as well as the C/N ratio of leaves. The magnitude of the changes is sufficient to negatively affect herbivore growth, survival and fecundity, which should have impacts on plant/herbivore interactions.", "keywords": ["0106 biological sciences", "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.

Therefore, it is important to qualify and to quantify the nutrient accumulation in the biomass of catch crop species. Since it was often described, that mixtures yield higher biomasses than pure stands of catch crops, we evaluated the nutrient scavenging potential of pure stands vs. mixtures. \nTest objects were the four species mustard, phacelia, bristle oat and Egyptian clover either grown in pure stands (sowing densities: mustard - 300, phacelia - 706, bristle oat - 588, Egyptian clover - 833) or in a 4-species mixture (sowing densities: mustard - 67, phacelia - 294, bristle oat - 53, Egyptian clover - 233). Additionally, a commercial mixture of the DSV with a higher species diversity called TerraLife MaisPro was included in the experiment. Their single-species nutrient accumulation was evaluated after 2.5 months of cultivation in total shoot material (dryed for 3 d at 80 \u00b0C and ground in a mill) obtained from two sites in Germany (Asendorf - Lower Saxony and Triesdorf - Bavaria), and at two initial starting points of the respective wheat-catch crop-maize long-term rotation (2015 and 2016) - in total 4 test environments. \nGenerally, nutrient concentrations in the shoot biomass often followed species-specific patterns, e.g. phacelia and oat which are described to have a shallow root system with a high amount of fine roots in the upper soil layers had consistently highest P and K concentrations, S, which is prone to leaching, was most concentrated in the cruciferous species mustard, Ca concentration was highest in phacelia but very low abundant in oat as grass species or Mg was highest in clover since photosynthesis rate must be kept high because biologically fixed N has to be incorporated into carbon skeletons. Increasing interspecific competition in the mix (at higher plant survival rates or at vigorous plant development) favored higher concentrations of several nutrients in some of the species, e.g. higher P concentration in phacelia when cultivated in the 4-species mix. Non-favorable conditions like less water availability led, against this, to higher N concentrations in clover likely due to the establishment of N fixation (Triesdorf 2015 and Asendorf 2016).\nHowever, total nutrient scavenging was largely influenced by the biomass formed by a catch crop variant. In this case, above-ground nutrient conservation capacities were mostly equally high in mustard, phacelia, partially oat and the mixed cultures. Only in one test environment (Triesdorf 2016) where quite loose pure stands established, the mixed cultivation offered a larger nutrient conservation capacity via the production of higher total biomass.", "formats": [{"name": "CSV"}], "keywords": ["Bodenbedeckung", "Bodennutzung", "Landwirtschaftliche Anlagen und Aquakulturanlagen", "Shoots", "Plant parts", "nutrient balance", "Avena", "Avena nuda", "Poaceae", "Mustard", "Sinapis alba", "Phacelia tanacetifolia", "Trifolium alexandrinum", "", "biomass", "biomass", "biomass", "biomass", "biomass", "biomass", "Elements", "Nitrogen", "Nitrogen content", "Phosphorus", "Carbon", "Magnesium", "Potassium", "Boron", "Aluminium", "Manganese", "Sulphur", "Zinc", "Iron", "Copper", "Calcium", "Catch cropping", "Crop rotation", "cropping systems", "Biological competition", "Interspecific competition", "Shoot biomass", "catch crops", "mineral elements", "macro elements", "micro elements", "C/N ratio", "plant nutrition", "ICP-OES", "EA", "opendata", "Boden"], "contacts": [{"name": "Heuermann, Diana", "organization": "Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) Gatersleben", "position": "Staff member (Molecular Plant Nutrition)", "roles": ["author"], "phones": [{"value": "0049394825514"}], "emails": [{"value": "heuermannd@ipk-gatersleben.de"}], "addresses": [{"deliveryPoint": ["Correnstra\u00dfe 3"], "city": "Stadt Seeland", "administrativeArea": "Saxony-Anhalt", "postalCode": "06466", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Wir\u00e9n, Nicolaus von", "organization": "Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) Gatersleben", "position": "Department head", "roles": ["projectLeader"], "phones": [{"value": "0049 39482 5603"}], "emails": [{"value": "vonwiren@ipk-gatersleben.de"}], "addresses": [{"deliveryPoint": ["Correnstra\u00dfe 3"], "city": "Stadt Seeland", "administrativeArea": "Saxony-Anhalt", "postalCode": "06466", "country": "Germany"}], "links": [{"href": null}]}, {"name": "BonaRes Data Centre", "organization": "Leibniz Centre for Agricultural Landscape Research (ZALF)", "position": "Research Platform 'Data' -

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 N, 13\u00b019\u201905.47\u2019\u2019 E, 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.
