Introduction Uruguayan agriculture’s transition to no-till farming and intensified practices, replacing crop-pasture (CP) systems with continuous cropping (CC) rotations, has disrupted biological nitrogen fixation (BNF). Despite this, diversified sequences, including C4 species, have maintained the soil organic carbon (SOC) balance under management, limited overall impacts on productivity sustainability. The effects of these changes wheat use efficiency (NUE) need be further investigated. Methods This study, conducted within a long-term experiment (LTE) rainfed conditions, compared in CP CC rotations. Wheat following were analyzed over three seasons. Variables measured included (N) concentration, grain yield (WGY), protein concentration (GPC), NUE. Four N fertilizer levels applied each rotation system assess their impact. Results consistently outperformed WGY, 2425 1668 kg ha −1 averages, respectively. showed slightly higher GPC (10.92%) than (10.48%). Nitrate-N at tillering positively correlated WGY negatively GPC, but relationship differed by rotation. Soil NUE indices Discussion study’s findings highlighted potential rotation, especially when species crop sequence, achieve short term due healthier conditions seeded after post-pasture CP. Additionally, our study highlights that effect previous was more relevant expected residual pasture phase CP, primarily quality residues temporary adverse compaction caused livestock trampling.

Cupressus funebris forests grow relatively fast and have a strong natural regeneration ability, showing great potential in carbon sequestration. Global warming has already had significant impact on its distribution pattern. This study used the Maximum Entropy Model (MaxEnt) data of communities to explore contraction expansion adaptive funebris. The research results are as follows: contemporary area is mainly located southern region China, accounts for approximately 7.15% total land area. main driving variables affecting annual precipitation, minimum temperature coldest month, isothermality, seasonality, carbonate content, altitude. Among them, climate plays dominant role this community. Under different emission scenarios future, areas show an trend, but most highly shrinking changes significant.

Layered fertilization parameters affects crop root system configuration and growth distribution, which in turn soil pore properties aggregate structure. Therefore, understanding the spatial distribution of space is helpful choosing a reasonable ratio production practice, ensures high stable yields at same time improves fertilizer utilization health. Albeit impact layered varied rates on characteristics profile microscale level remains limited. This study quantifies impacts under rapeseed using analysis X-ray computed tomography (XCT). A new pattern that shallow-deep layer synchronized mechanical sowing was using, rotary tillage mixed shallow 10 cm side-deep band deeper layer. It set five ratios amounts between deep layers as 0:4 (FD), 1:3 (FL), 2:2 (FM), 3:1 (FH), 4:0 (F0), with non-fertilization (CK) control treatment. The results indicated effectively improved rape conformation significantly increased total porosity moisture content, reduced bulk density resistance (P < 0.05). Additionally, closely related to structure yield. Notably, compared other treatments, macroscopic porosity, equivalent diameter, hydraulic radius roundness FM treatment are improved, it yield quality rapeseed. Correlation showed were negatively correlated but positively macropore morphology Our demonstrate can its effect depends good created by ratio, provided theoretical basis for high-yield, efficient, green, sustainable mechanized direct-sowing

Soil compaction is an agricultural challenge with profound influence on the physical, chemical, and biological properties of soil. It causes drastic changes by increasing mechanical impedance, reducing water infiltration, gaseous exchange, activities. hinders root growth, limiting nutrient foraging abilities plants. Recent research reveals that plant roots sense soil due to higher ethylene accumulation in around tips. Ethylene orchestrates auxin abscisic acid as downstream signals regulate adaptive responses compaction.
