A long-term experiment (1972\uffe2\uff80\uff931992) run in Benin consisted of two phases: a depletion phase (1972\uffe2\uff80\uff931980) with varying levels of mineral and organic fertilisation, and a regeneration phase (1981\uffe2\uff80\uff931992) where all plots received full fertilisation and organic matter additions. Soils were sampled at 0\uffe2\uff80\uff9320\uffc2\uffa0cm depth in 1973, 1974, 1982, and 1989 to assess fertility changes. Mineral fertilisation (N, P, K) and plant biomass management (crop residue retention and biomass additions) significantly influenced seed cotton and maize grain yields during the depletion phase. Soil organic carbon declined consistently in all treatments during depletion but remained stable during regeneration. The long-term effect was evident only in seed cotton yield during depletion. In contrast, due to high variability, maize grain yield showed no consistent trend. The combined use of organic resources and mineral fertilisers helped maintain crop productivity but led to declining soil chemical properties in this Ferralsol. The analysis of this outdated yet unpublished dataset shed light on how long-term soil depletion effects persist over time, even when soil fertility management is restored, indicating a sort of \uffe2\uff80\uff98soil memory\uffe2\uff80\uff99. The persistence of these effect suggests that regenerative interventions must begin before critical thresholds of degradation are crossed. Future research should focus on alternative measures to restore/maintain soil fertility not evaluated in this experiment, such as conservation tillage or legume integration, to provide long-term benefits for smallholder farmers facing soil fertility challenges.</p", "keywords": ["Crop residues", "diversification", "propri\u00e9t\u00e9 physicochimique du sol", "IMPACT", "http://aims.fao.org/aos/agrovoc/c_7170", "rendement des cultures", "Cotton-maize yields", "Nutrient cycling", "http://aims.fao.org/aos/agrovoc/c_875", "fertilisation", "CARBON", "CROP PRODUCTIVITY", "http://aims.fao.org/aos/agrovoc/c_10176", "Long-term experiment", "mauvaise herbe", "http://aims.fao.org/aos/agrovoc/c_2018", "http://aims.fao.org/aos/agrovoc/c_7165", "[SDV.SA.SDS] Life Sciences [q-bio]/Agricultural sciences/Soil study", "COMPOST", "pratique culturale", "http://aims.fao.org/aos/agrovoc/c_8511", "http://aims.fao.org/aos/agrovoc/c_10795", "http://aims.fao.org/aos/agrovoc/c_7168", "http://aims.fao.org/aos/agrovoc/c_35657", "Gossypium", "Soil organic carbon", "MEMORY", "http://aims.fao.org/aos/agrovoc/c_7182", "Soil's memory", "non-travail du sol", "http://aims.fao.org/aos/agrovoc/c_8fc04948", "http://aims.fao.org/aos/agrovoc/c_331583", "STATE", "ORGANIC-MATTER", "fertilit\u00e9 du sol", "s\u00e9questration du carbone", "http://aims.fao.org/aos/agrovoc/c_8347", "YIELD", "d\u00e9gradation du sol", "conservation des sols", "MINERAL FERTILIZER", "http://aims.fao.org/aos/agrovoc/c_3335", "gestion int\u00e9gr\u00e9e de la fertilit\u00e9 des sols", "http://aims.fao.org/aos/agrovoc/c_2344", "mati\u00e8re organique du sol"]}, "links": [{"href": "https://doi.org/10.1007/s10705-025-10429-1"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Nutrient%20Cycling%20in%20Agroecosystems", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.1007/s10705-025-10429-1", "name": "item", "description": "10.1007/s10705-025-10429-1", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.1007/s10705-025-10429-1"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-08-20T00:00:00Z"}}, {"id": "10.1007/s00374-011-0539-3", "type": "Feature", "geometry": null, "properties": {"updated": "2026-05-25T16:14:18Z", "type": "Journal Article", "created": "2011-01-18", "title": "Effects Of Organic And Inorganic Fertilization On Soil Bacterial And Fungal Microbial Diversity In The Kabete Long-Term Trial, Kenya", "description": "The effects of crop manure and inorganic fertilizers on composition of microbial communities of central high land soils of Kenya are poorly known.

We examined 16S rRNA gene and 28S rRNA gene fingerprints of bacterial and fungal diversity by PCR amplification and denaturing gradient gel electrophoresis separation, respectively. The PCR bacterial community structure and diversity were negatively affected by N2P2 and were more closely related to the bacterial structure in the soils without any addition (control) than that of soils with a combination of inorganic and organic or inorganic fertilizers alone. The effect on fungal diversity by N2P2 was different than the effect on bacterial diversity since the fungal diversity was similar to that of the N2P2 + FYM and N2P2 + MS-treated. However, soils treated with organic inputs clustered away from soils amended with inorganic inputs.

Our aim was to test this hypothesis for intercropped durum wheat and faba bean along a P-fertilizer gradient. A field experiment was conducted in a long-term P-fertilizer trial with three rates of P-fertilization (No, Low and High P). Microbial biomass was assessed by chloroform fumigation-extraction. Quantitative PCR was applied to evaluate the abundance of relevant microbial groups. Phosphorus availability and microbial biomass systematically increased in the rhizosphere compared to bulk soil. P-fertilization resulted in higher abundance of targeted bacterial phyla, whole bacterial and fungal communities, and depressed mycorrhizal colonization of durum wheat, but not faba bean. Microbial biomass carbon significantly increased in the rhizosphere only in P-fertilized treatments, pointing to P limitation of microbial communities. Intercropping yielded a significant effect on rhizosphere microbial properties only at High P. Microbial biomass P increased in the rhizosphere of intercropped faba bean only at No P level, and was thus the sole finding supporting the stress-gradient hypothesis. P-fertilization was the main driver of microbial communities in this field trial, and P-fertilizer application modulated the species-specific effect in the intercrop.

We found 1) no significant effect of shade trees on coffee production overall; 2) evidence that shade trees do affect flowering and subsequent cherry development, with effects strongly dependent on climate and annual variations in coffee plant physiology; 3) Erythrina shade trees significantly increased soil litter and relative infiltration rate of water in the soil, both linked to soil conservation and decrease in erosion; 4) even in highly fertilized environments, Erythrina trees do fix N which was taken up by adjacent coffee plants. The lack of significant negative effect of shade trees on overall coffee yield and the observation of the provision of other useful services was not unexpected, because of 1) the low density of shade trees in the study site (100\u2013350 trees/ha pruned twice a year on average) and 2) the sensitivity of coffee yields to other interacting effects such as climate, pests and diseases and physiological variations in the plant.

Samples of the soil were taken from 0 to 5\u00a0cm soil layer of three direct seeding mulch-based cropping systems (DMC using crop residues and living mulches). The samples were compared with samples from conventionally tilled plots (CT) and natural fallows (NF). The field experiments were carried out over a 12-year-period and two types of amendment were applied once a year at sowing, farmyard manure (FYM) and farmyard manure combined with an NPK chemical fertilizer. The C and N content, microbial basal respiration and biomass and \u03b2-glucosidase, urease and acid phosphatase activities were determined. The results showed that there was no interaction between soil management strategies and the use of fertilizer. Furthermore, the fertilizer did not affect the soil C and N content or the acid phosphatase and urease activities. Farmyard manure with added NPK had a significantly greater effect than farmyard manure on its own, increasing the microbial biomass, soil respiration and \u03b2-glucosidase activity up to 26%, 52% and 20%, respectively but there was no significant difference between natural fallows and direct seeding mulch-based cropping systems.

The results for direct seeding mulch-based systems varied according to the microbial activities measured. However, soil \u03b2-glucosidase and acid phosphatase activities were significantly higher for the direct seeding mulch-based systems using crop residues than for the direct seeding mulch-based systems using living mulches. Direct seeding mulch-based systems with Desmodium uncinatum living mulch had significantly lower microbial biomass and respiration than the other direct seeding mulch-based systems.

The objectives of our study were: (1) to quantify the effects of contrasting organic residue (OR) retention methods on tree growth and soil nutrient pools over a full  Eucalyptus  rotation and (2) to assess the potential of soil analyses to predict yields of fast-growing plantations established on tropical sandy soils. An experiment was set up in the Congo at the harvesting of the first rotation after afforestation of a native herbaceous savanna. Six treatments were set up in 0.26\u00a0ha plots and replicated in 4 blocks, with OR mass at planting ranging from 0 to 46.5\u00a0Mg\u00a0ha \u22121 . Tree growth over the whole rotation was highly dependent on OR management at planting. Over-bark trunk volume 7 years after planting ranged from 96\u00a0m 3 \u00a0ha \u22121  in the treatment with forest floor and harvest residue removal at planting to 164\u00a0m 3 \u00a0ha \u22121  in the treatment with the largest amount of OR. A comparison of nutrient stocks within the ecosystem at planting and at the end of the rotation suggested that nutrient contents in OR were largely involved in the different response observed between treatments. OR management treatments did not significantly modify most of the nutrient concentrations in the upper layers of the mineral soil. Conventional soil analyses performed before planting and at ages 1 and 3 years were unable to detect differences between treatments despite large differences in tree growth. In contrast, linear regressions between stand aboveground biomass at harvesting and OR mass at planting (independent variable) showed that OR mass was an excellent predictor of stand yield ( R  2 \u00a0=\u00a00.99). A large share of soil fertility comes from organic material above the mineral soil in highly weathered sandy soils and OR mass at planting might be used in conjunction with soil analyses to assess the potential of these soils to support forest plantations.", "keywords": ["0106 biological sciences", "570", "http://aims.fao.org/aos/agrovoc/c_7170", "[SDV]Life Sciences [q-bio]", "rendement des cultures", "Slash", "F62 - Physiologie v\u00e9g\u00e9tale - Croissance et d\u00e9veloppement", "for\u00eat tropicale", "01 natural sciences", "630", "http://aims.fao.org/aos/agrovoc/c_10176", "http://aims.fao.org/aos/agrovoc/c_24904", "sol tropical", "http://aims.fao.org/aos/agrovoc/c_16118", "http://aims.fao.org/aos/agrovoc/c_5387", "2.

A long-term experiment (1972\uffe2\uff80\uff931992) run in Benin consisted of two phases: a depletion phase (1972\uffe2\uff80\uff931980) with varying levels of mineral and organic fertilisation, and a regeneration phase (1981\uffe2\uff80\uff931992) where all plots received full fertilisation and organic matter additions. Soils were sampled at 0\uffe2\uff80\uff9320\uffc2\uffa0cm depth in 1973, 1974, 1982, and 1989 to assess fertility changes. Mineral fertilisation (N, P, K) and plant biomass management (crop residue retention and biomass additions) significantly influenced seed cotton and maize grain yields during the depletion phase. Soil organic carbon declined consistently in all treatments during depletion but remained stable during regeneration. The long-term effect was evident only in seed cotton yield during depletion. In contrast, due to high variability, maize grain yield showed no consistent trend. The combined use of organic resources and mineral fertilisers helped maintain crop productivity but led to declining soil chemical properties in this Ferralsol. The analysis of this outdated yet unpublished dataset shed light on how long-term soil depletion effects persist over time, even when soil fertility management is restored, indicating a sort of \uffe2\uff80\uff98soil memory\uffe2\uff80\uff99. The persistence of these effect suggests that regenerative interventions must begin before critical thresholds of degradation are crossed. Future research should focus on alternative measures to restore/maintain soil fertility not evaluated in this experiment, such as conservation tillage or legume integration, to provide long-term benefits for smallholder farmers facing soil fertility challenges.</p", "keywords": ["Crop residues", "propri\u00e9t\u00e9 physicochimique du sol", "IMPACT", "rendement des cultures", "Cotton-maize yields", "http://aims.fao.org/aos/agrovoc/c_875", "fertilisation", "CARBON", "Long-term experiment", "mauvaise herbe", "http://aims.fao.org/aos/agrovoc/c_2018", "[SDV.SA.SDS] Life Sciences [q-bio]/Agricultural sciences/Soil study", "COMPOST", "http://aims.fao.org/aos/agrovoc/c_8511", "http://aims.fao.org/aos/agrovoc/c_10795", "http://aims.fao.org/aos/agrovoc/c_35657", "Cotton\u2013maize yields", "http://aims.fao.org/aos/agrovoc/c_7182", "Soil's memory", "non-travail du sol", "http://aims.fao.org/aos/agrovoc/c_8fc04948", "STATE", "[SDV] Life Sciences [q-bio]", "http://aims.fao.org/aos/agrovoc/c_8347", "ORGANIC-MATTER", "s\u00e9questration du carbone", "fertilit\u00e9 du sol", "Soil\u2019s memory", "http://aims.fao.org/aos/agrovoc/c_3335", "gestion int\u00e9gr\u00e9e de la fertilit\u00e9 des sols", "mati\u00e8re organique du sol", "diversification", "http://aims.fao.org/aos/agrovoc/c_7170", "Nutrient cycling", "CROP PRODUCTIVITY", "http://aims.fao.org/aos/agrovoc/c_10176", "B\u00e9nin", "http://aims.fao.org/aos/agrovoc/c_7165", "pratique culturale", "http://aims.fao.org/aos/agrovoc/c_7168", "Longterm experiment", "Gossypium", "Soil organic carbon", "MEMORY", "http://aims.fao.org/aos/agrovoc/c_331583", "YIELD", "d\u00e9gradation du sol", "conservation des sols", "MINERAL FERTILIZER", "http://aims.fao.org/aos/agrovoc/c_2344"]}, "links": [{"href": "https://doi.org/11370/a5fba259-dd61-43ac-8b8a-86b2d5fd6cef"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Nutrient%20Cycling%20in%20Agroecosystems", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "11370/a5fba259-dd61-43ac-8b8a-86b2d5fd6cef", "name": "item", "description": "11370/a5fba259-dd61-43ac-8b8a-86b2d5fd6cef", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/11370/a5fba259-dd61-43ac-8b8a-86b2d5fd6cef"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2025-08-20T00:00:00Z"}}], "links": [{"rel": "self", "type": "application/geo+json", "title": "This document as GeoJSON", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=http%3A%2F%2Faims.fao.org%2Faos%2Fagrovoc%2Fc_7170&f=json", "hreflang": "en-US"}, {"rel": "alternate", "type": "text/html", "title": "This document as HTML", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=http%3A%2F%2Faims.fao.org%2Faos%2Fagrovoc%2Fc_7170&f=html", "hreflang": "en-US"}, {"rel": "collection", "type": "application/json", "title": "Collection URL", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main", "hreflang": "en-US"}, {"type": "application/geo+json", "rel": "first", "title": "items (first)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=http%3A%2F%2Faims.fao.org%2Faos%2Fagrovoc%2Fc_7170&", "hreflang": "en-US"}, {"rel": "last", "type": "application/geo+json", "title": "items (last)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=http%3A%2F%2Faims.fao.org%2Faos%2Fagrovoc%2Fc_7170&offset=11", "hreflang": "en-US"}], "numberMatched": 11, "numberReturned": 11, "distributedFeatures": [], "timeStamp": "2026-05-25T23:21:27.069360Z"}
