The implementation of conservation tillage is crucial for the preservation and utilization black soil. This study examined 297 new agricultural management entities in five pilot counties soil region northeast China. Using SBM-Undesirable model, this measured evaluated green total factor productivity (AGTFP) these entities. We further employed Tobit model to explore impact on AGTFP. findings revealed that average AGTFP value sample was 0.4364, indicating a generally low degree exhibited significant variation. Improvement input indicators (such as machinery) undesirable output net carbon emissions) particularly needed. Additionally, had positive AGTFP, with higher number applied technologies correlating increased productivity. Material subsidies offered greater direct cost relief stronger effect comparison cash subsidies. Furthermore, apart from policy factors, key production operation characteristics—such access materials—also significantly influenced results offer valuable decision-making framework scientific reference countries regions worldwide, enabling them enhance sustainable vital resource.

Straw Return or No Tillage? Comprehensive Meta-Analysis Based on Soil Organic Carbon Contents, Carbon Emissions, and Crop Yields in China

Conservation tillage methods, including straw return (SR) and no (NT), are widely used to improve the soil organic carbon (SOC) content crop yield. However, applying SR or NT separately has become a common practice for farmers producing different crops those in regions. Evaluating effects of on SOC content, emissions, yield important guiding correct application conservation promoting sustainable agricultural development. Therefore, we conducted meta-analysis based 1014 sets data obtained China assess Compared with return, increased by 10% 8.6%, respectively, but significant impact emissions. conventional tillage, 2.9% reduced emissions 18% 3.9%, respectively. We also found that combined had an additive effect, where combination improved more than alone. If alone, specific climatic conditions, characteristics, field management strategies need be considered maximize SOC. In particular, should limited hydrothermal conditions (low temperature low precipitation) areas rice–wheat rotation is implemented. can under any climate it effectively increase continuous wheat cropping areas.
