Global climate change and the increasing population have increased difficulties associated with grain production. Several measures been established to maintain a high crop yield, while preserving or soil health, including biochar application soil, producing new complex amendment application, e.g., soft rocks. However, previous studies focused on effect of single but not considered rotation. In this study, field plots foxtail millet cultivated for two years under rock were selected licorice cultivation detect effects properties yield. The results showed that biochar-treated plot had highest biomass (251.76 g/m2), followed by combined treatment, control treatments lowest (97.65 g/m2). Plants in liquiritin glycyrrhizic acid contents, those treatment. Soft rocks catalase activity, organic matter, oxalic acid, tartaric formic available phosphorus (AP). Correlation analysis was significantly positively correlated AP negatively pH. activity (p < 0.05) pH 0.05). Therefore, it can be concluded addition could increase contents (especially acid), which function reduce pH, content, enhance biomass.

Full-film double-ridge furrow sowing technology (FDRFST) and nitrogen (N) management are crucial for sustainable agricultural development. To investigate the N fertilizer application scheme spring maize with high yield, precipitation water productivity (PWP), use efficiency (NUE) under FDRFST, a two-year field experiment was carried out in rainfed area of Longzhong (LZ). Treatments included two types fertilization (common urea [U] controlled release [CU]), three rates (180, 225, 270 kg hm−2), conditions no plastic film mulching. The results showed that temperature-increase effect PM on soil between 2021 2022 concentrated 0–90 days, average values 5 cm temperature increasing by 4.15 3.58 ºC, respectively. However, rate had negligible effects temperature. Plastic mulching (PM) required compensation, particularly during sowing–emergence stage, 1.68 compensation coefficient. Based simulation modified DNDC model, recommended CU (180 hm−2) LZ increased PWP, NUE 15.8%, 16.0%, 36.4% from 1981 to 2020, respectively, compared U treatments. Our provide theoretical basis production offer critical insights improving model conditions.

Optimizing management practices is essential to guarantee crop yield and reduce greenhouse gas emissions for the sustainable agricultural production under climate change. The objectives of this study were i) calibrate evaluate Denitrification-Decomposition (DNDC) model using measurements maize yield, nitrogen (N) uptake, soil temperature, moisture, inorganic N nitrous oxide (N2O) from a 5-year field experiment in Northeast China (NEC) ii) simulate impacts change on N2O explore adaptation strategies based DNDC modelling. For N-fertilized treatments (farmers' practice, FP-N; current optimized management, OPT-N), overall showed "good" performance simulating aboveground biomass, uptake average statistical values. also performed well temperature emissions. N-unfertilized treatments, however, overestimated mainly due overestimation growth low-temperature stress conditions, underestimation resulted underestimated mineralization availability dissolved pools continuous deficiency. that compared baseline scenario, future would improve (1.4–8.8%) while increasing (37.6–83.4%) without measures NEC. Compared OPT-N solely adjusting fertilization rate (200–220 kg ha−1) concurrently increase (5.0–8.7%) (0.9–18.6%), adoption planting dates (April 27th May 18th), new cultivars (with thermal degree days ranging 2550 2700 °C), implementation no-tillage maize-soybean rotation by 1.8–8.9% 0.7–26.5% scenarios.

Climate change refers to significant alterations in long-term climate conditions. If greenhouse gas emissions continue rise, there is a high probability of exceeding the 1.5°C and 2° thresholds global warming throughout 21st century. This situation poses serious threat agriculture sector can lead decline agricultural production reduction product quality. Additionally, intensive farming practices decrease resilience agriculture. study aims examine effects on sector, explain concept modeling parameters that be measured, provide guidance how studies alfalfa, similar crops improved by identifying their shortcomings. The method used many different fields creating abstract representations real-world objects or events via mathematical equation, writing algorithm, simulation. Parameters alfalfa include yield, growth, carbon, water, nitrogen balance, effects, other factors. However, these models have shortcomings such as need for more comprehensive data collection testing, requirement parameter adjustments, inability address various growth cycles, lack simulation crown root roles sensitivity measuring soil input factors, limited testing research, inaccuracies automatic classification, absence yield models, deep learning techniques. Addressing crucial achieving reliable effective results sector. Strengthening addressing deficiencies potential robust sustainable solutions
