Under Mediterranean rainfed areas, no-till cereal-based systems have been adopted to cope with water availability and increasing input costs. However, the increased risk of biotic stresses, high N-fertilizer dependence, current EU policies warrant cropping re-design. Evaluate diversification N fertilization as strategies improve use efficiency at system level quantify its productivity. Four crop sequences combined four levels were assessed in a three-year field experiment semiarid north-eastern Spain.

Effectiveness of soil management strategies for mitigation of N₂O emissions in European arable land: A meta‐analysis

European Journal of Soil Science, Journal Year: 2024, Volume and Issue: 75(3)

Published: May 1, 2024

Abstract Soil management strategies involving the application of organic matter (OM) inputs (crop residues, green and livestock manure, slurry, digestate, compost biochar) can increase soil carbon storage but simultaneously lead to an in non‐CO 2 greenhouse gas (GHG) emissions such as N O. Although multiple meta‐analyses have been conducted on topic OM input impacts GHG, none has focused specifically European arable soils. This study plugs this gap assist policymakers steering agriculture a more sustainable direction. The objective meta‐analysis was quantify how different nature quality, also strategy, mitigate O pedoclimatic conditions Europe. We quantitatively synthesised results over 50 field experiments 15 countries. Diverse crops, mainly cereals, were cultivated monoculture or crop rotations mineral Cumulative monitored during periods 30–1070 days treatments, which received inputs, alone combination with fertiliser; controls fertilised N. overall effect had slight tendency reduce by 10% ( n = 53). With increasing carbon‐to‐nitrogen ratio mitigation became pronounced. In particular, biochar significantly reduced 25% 6) 33% 8) respectively. However, their strongly depended characteristics.

Remote sensing of depth-induced variations in soil organic carbon stocks distribution within different vegetated landscapes

CATENA, Journal Year: 2024, Volume and Issue: 243, P. 108216 - 108216

Published: June 26, 2024

The preservation and augmentation of soil organic carbon (SOC) stocks is critical to designing climate change mitigation strategies alleviating global warming. However, due the susceptibility SOC environmental topo-climatic variability changes, it essential obtain a comprehensive understanding state current both spatially vertically. Consequently, effectively assess storage sequestration capacity, precise evaluations at multiple depths are required. Hence, this study implemented an advanced Deep Neural Network (DNN) model incorporating Sentinel-1 Synthetic Aperture Radar (SAR) data, features, physical properties predict (0-30cm, 30-60cm, 60-100cm, 100-200cm) across diverse land-use categories in KwaZulu-Natal province, South Africa. There was general decline accuracy DNN model's prediction with increasing depth, root mean square error (RMSE) ranging from 8.34 t/h 11.97 for four depths. These findings imply that link between covariates weakens depth. Additionally, distinct factors driving were discovered topsoil deep-soil, vegetation having strongest effect topsoil, topo-climate becoming more important as depth increases. This underscores importance depth-related modelling. Grasslands had largest stocks, while commercial forests have highest rates per unit area. offers valuable insights policymakers provides basis devising regional management can be used mitigate change.

Soils have the potential to sequester and store significant amounts of carbon, contributing towards climate change mitigation. Soil carbon markets are emerging pay farmers for management changes that absorb atmospheric governed by codes ensure eligibility, additionality permanence whilst protecting against leakage reversals.

Interactive effects of agricultural management on soil organic carbon accrual: A synthesis of long-term field experiments in Germany

Geoderma, Journal Year: 2023, Volume and Issue: 438, P. 116616 - 116616

Published: July 30, 2023

Crop production often leads to soil organic carbon (SOC) losses. However, under good management practice it is possible maintain and even re-accumulate SOC. We evaluated how different cropland techniques affected SOC stocks in the topsoil (0–30 cm depth) of 10 long-term experiments (LTE) Germany. found that were particularly enhanced by mineral fertilization amendments like straw incorporation a smaller degree irrigation, but only slightly choice preceding crops. In agreement with global meta-analyses, liming reduced tillage had little or negative effects on storage, also depended fertilization. Management dependent texture: sandy soils showed lowest 20.9 ± 2.3 (standard error mean) Mg ha−1, exhibited largest relative response options. Annual changes ranged from −3.0 ‰ no N fertilization, + 6.1 farmyard manure application, using mineral-fertilized limed treatment as reference. Even higher rates up 10.6 yr−1 reached combination irrigation incorporation. Note contribution accrual thus climate change mitigation must be adjusted for reduction at sites which was removed. Overall, potential agricultural influence enhance significant. This controlled type land-use duration, overall stocks, characterized antagonistic synergistic practices.

Compared with the ever-growing information about anthropogenic discharge of nutrients, metals, and antibiotics on disturbance antibiotic resistance genes (ARGs), less is known how potential natural stressors drive evolutionary processes resistance. This study examined soil resistomes evolved differentiated over 30 years in various land use settings spatiotemporal homogeneity minimal human impact. We found that contents organic carbon, nitrogen, microbial biomass, bioavailable heavy as well related changes resistome prevalence including diversity abundance, declined order grassland > cropland bareland. Sixty-nine remaining ARGs 14 mobile genetic elements (MGEs) were shared among three uses. Multiple factors (i.e., properties, bacterial community, MGEs) contributed to resistome, wherein profile was dominantly driven by MGEs from both direct indirect pathways, supported a partial least-squares path model analysis.

Although only 30% of total Brazilian agricultural areas are used for crop and livestock, full soil potential needs to be evaluated due environmental legal impossibility expand agriculture new areas. A novel approach assess productive soils, called "SoilPP" based analysis (0-100 cm) - which express its pedological information machine learning presented. Historical yields sugarcane soybeans were analyzed, allowing identify where it still possible improve yields. The soybean below estimated SoilPP 46% counties could improved by proper management practices. For sugarcane, 38% can improved. This technique allowed us understand map yield situation over large areas, support farmers, consultants, industries, policymakers, world security planning.
