This study aims to investigate the early post-termination phase as a critical window for assessing soil responses and improving agricultural management decisions. The experiment was conducted in Southern Italy and arranged as a split–split plot design involving three factors: irrigation system (sprinkler vs. drip); cover crop mixture (fava bean, oat, and rapeseed, vs. vetch, barley, and white mustard); and cover crop termination method (incorporation vs. mulch). Four soil parameters were selected for this experiment: soil organic matter, soil aggregate stability, total nitrogen, and soil infiltration rate. Findings highlight no significant differences in total nitrogen among treatments, whereas the soil infiltration rate increased in drip-irrigated treatments and decreased in sprinkler-irrigated ones. Soil aggregate stability increased across all treatments, as did soil organic matter, which increased by approximately 20% within a few weeks. Overall, the irrigation system acted as the main regulator of early soil physicochemical responses. The interaction between irrigation system and cover crop termination methods produced the largest differences among the investigated parameters. The combination of sprinkler irrigation and biomass incorporation resulted in the highest increase in soil organic matter.
This study explores the sustainable optimization of Valencia orange production in Egypt's arid regions by analyzing the dual effects of deficit irrigation and biochar soil conditioning. Multi-season field experiments demonstrated that Partial Root-zone Drying (PRD) combined with 1200 kg ha⁻¹ of biochar significantly en...

The purpose of this study was to quantify water use and yield of tomato crops grown on biochar-amended soils in tropical conditions of Ibadan, Nigeria. Field experiments incorporated FAO AquaCrop and CROPWAT alongside five levels of biochar application (0, 5, 10, 15 and 20 t ha⁻¹). Reference evapotranspiration was esti...

Cover crops have been recognized as a sustainable practice to improve soil structure and fertility in intensive agroecosystems, yet quantitative evidence on their effects and underlying mechanisms remains limited in high-altitude cereal cropping systems. This study investigated the effects of diverse cover crops on soi...
