Plants uptake and assimilate nitrogen from the soil in form of nitrate, ammonium ions, available amino acids organic sources. Plant nitrate transporters are responsible for translocation into roots. The unique structure these determines specificity each transporter, structural analyses reveal mechanisms by which function. Following absorption, metabolism pathway incorporates compounds via glutamine synthetase glutamate synthase that convert ions glutamate. Different isoforms exist, enabling plants to fine-tune based on environmental cues. Under stressful conditions, nitric oxide has been found enhance plant survival under drought stress. Furthermore, interaction between salinity stress availability studied, with identified as a potential mediator responses salt Conversely, excessive use fertilizers can lead health issues. Therefore, alternative strategies, such establishing fixation through diazotrophic microbiota, have explored reduce reliance synthetic fertilizers. Ultimately, genomics identify new genes related fixation, could be harnessed improve productivity.

Soil organic carbon sequestration in agricultural long-term field experiments as derived from particulate and mineral-associated organic matter

Soil organic matter (SOM) is indispensable for soil health and, in the context of climate change, considered a significant CO2 sink. Improving agricultural management to increase long-term carbon (SOC) stocks mitigating change requires tools that estimate short and long-cycling SOM pools. In this study, we analyzed changes fast-cycling particulate (POM) slow-cycling mineral-associated (MAOM) induced by common practices, i.e., fertilization crop rotation topsoils from 25 Central European field experiments. When relating MAOM-C contents recent saturation levels, estimated sequestration potentials were only met coarse-textured soils under appropriate or fine-textured extreme fertilization. texture, fertilization, below-ground OC inputs through root exudates biomass decisive estimating MAOM-C, allowing calibration mixed-effects model (Nakagawa's: marginal R2m = 0.6, conditional R2c 0.89).

Twenty percent of agricultural management effects on organic carbon stocks occur in subsoils – Results of ten long-term experiments

Agriculture Ecosystems & Environment, Journal Year: 2023, Volume and Issue: 356, P. 108619 - 108619

Published: June 7, 2023

Agricultural management can influence soil organic carbon (SOC) stocks and thus may contribute to sequestration climate change mitigation. The depth which agricultural practices affect SOC is uncertain. Soil have an important bearing on dynamics, so it consider effects capture fully changes in stocks. This applies particular the evaluation of farming measures, are becoming increasingly due change. We sampled analysed upper metre mineral cropland soils from ten long-term experiments (LTEs) Germany quantify depth-specific common practices: nitrogen (N) fertilisation, a combination N, phosphorus (P) potassium (K) irrigation, crop rotation with preceding crops (pre-crops), straw incorporation, application farmyard manure (FYM), liming, reduced tillage. In addition, compaction were examined as negative side effect management. Results showed that 19 ± 3 % total found subsoil (30–50 cm) 4 lower (50–100 cm), including all significant topsoil effects, while 79 7 (0–30 cm). Nitrogen NPK fertilisation treatments had greatest (OC) stocks, followed by FYM incorporation. Sampling down 50 cm resulted significantly higher than when considering only. A pre-crops, tillage did not at any increment. Since approximately 20 impact occurs subsoil, we recommend monitoring programs schemes extend their standard sampling SOC.

Abstract Conventional tillage (CT) is a widely used agricultural practice aimed at loosening soil to enhance water infiltration and root growth. However, it can lead environmental issues such as increased erosion loss of nutrients carbon. To address these challenges, non‐conventional systems like no‐tillage minimum (collectively referred NT) have gained popularity in recent decades. This review examines the effects CT NT on root: shoot ratio (R:S) based 28 studies covering common crops across various climates managements. Most were primarily maize, wheat, rapeseed barley. Meta‐analysis showed non‐significant differences ( p = .27) among with respect their response R:S two practices. Rapeseed barley exhibited higher by 2% 15%, while maize wheat demonstrated 6%, respectively, although where not significant.
