The degradation of black soil cropland has occurred to varying degrees in the northern agropastoral ecotone. Crop–forage rotation is an effective way improve quality, with Medicago being preferred perennial legume. C, N, and P stoichiometric ratios are key indicators quality organic matter composition, reflecting status internal cycles soil. This study aims investigate ecological grassland soils different planting durations, explore regulatory effects nitrogen fertilizer on carbon (SOC), total (TN), phosphorus (TP) content, assess impacts these changes ecosystem. was conducted long-term cultivated core experimental platform Hulunber National Field Station. Based forage yield nutrient measurements, field-based observations laboratory analyses were carried out. × varia subject, treatments: CK (0 kg N ha−1), N75 (75 N150 (150 ha−1).

Phosphorus (P) is a key limiting factor in crop growth and essential for agriculture. As plant uptake of P inefficient, it commonly applied to maintain yields leading range negative environmental issues when excess. Additionally, mineral fertilisers derived from mined rock phosphate, which finite resource that needs be sustainably managed order food security the long-term. Phosphatase activity one several mechanistic responses deficiency plant-soil system, enabling mineralization organic increase availability both plants soil organisms. In this study we address need further understanding role phosphatase enzyme acquisition agricultural settings, using systematic review literature subsequent meta-analysis. We find monoesterase inhibited by inorganic (−23%, −39.8 −2.2%) yet enhanced (+74%, 8.4–232.1%). This indicates important deficient systems, more determining than level deficiency. also investigated other factors such as nitrogen addition, pH substrate changes composition physiology but, none these explained significant variance data. highlight consistent recording reporting additional variables association with assay data, required enable quantification potential utilisation resources agriculture, contribution semi-natural ecosystems.

Repeated applications of phosphorus (P) fertilizers result in the buildup P soil (commonly known as legacy P), a large fraction which is not immediately available for plant use. Long-term and accumulations an inefficient use dwindling supplies can nutrient runoff, often leading to eutrophication water bodies. Although problematic some regards, it conversely may serve source crop could potentially decrease dependence on external fertilizer inputs. This paper reviews (1) current knowledge occurrence bioaccessibility different chemical forms soil, (2) transformations with mineral organic relation their potential bioaccessibility, (3) approaches associated challenges accessing native that be used harness production. We highlight how inorganic vary depending properties, such pH matter content. also found accumulation changes more than species cessations. discuss progress P, including natural genetically modified plant-based strategies, P-solubilizing microorganisms, immobilized P-hydrolyzing enzymes.

Plants release a large variety of metabolites via their roots to shape physico-chemical soil properties and biological processes in the rhizosphere. While hydroponic growth conditions facilitate accessibility root system recovery exudates, natural environment can alter metabolism exudate secretion, raising question what extent quantity composition exudates released systems reflect those recovered from soil-grown roots.Using washing method, we sampled four field-grown cover crop species with wide taxonomic distance, namely white mustard, lacy phacelia, bristle oat, Egyptian clover. A set primary secondary were analysed targeted untargeted LC-MS-based approach, respectively, for comparison obtained hydroponically cultured plants.We found that cultivated plants larger amount total carbon, but carbon was not indicative diversity exudates. In field, phacelia clover contained 2.4 3.8 times more metabolites, whereas exudation hydroponics 5- 4-fold higher. The identified using approach much distinct among all than quantified metabolites. Among metabolite classes, presence lipids lipid-like molecules highly field samples, while phenylpropanoids, organoheterocyclic compounds or benzenoids characteristic clover, mustard irrespective cultivation condition. However, at compound level bulk specific every species, which implies poorly metabolic complexity plants.

The importance of habitat spatial variability as a key driver soil biota patterning (e.g., nematodes) has lately gained lot attention. As result, rhizosphere distinct faunal assemblage than bulk soil, but less is known about the nematodes and causes these changes in maize-alfalfa agroecosystems. purpose this study was to assess dynamic across soils when maize alfalfa were grown separately combination at varying degrees nitrogen fertilizer. results field experiment 2 × 3 factorial completely randomized block design revealed that total nematode omnivore-predator abundance, well generic diversity richness, maturity, structure indices, significantly increased monoculture mixture with compared soil. Furthermore, we discovered elevated levels sugars organic acids soils.
