Abstract

Creating a soil habitat is the first step to manage soil health for long-term soil quality and output. This means using soil management methods that lessen the soil uproar. An experiment was established in 2016 and 2017 on a middle term (7 years) consistent tillage method in typical Latosolic red soil of Southern China to access the effects of four treatments: subsoiling (SS), two passes of rotary tillage (2RT), two passes of rotary tillage + subsoiling (2RTSS), and zero tillage (ZT), on soil organic carbon, soil total nitrogen, soil biological activities (bacteria, fungi, actinomycetes, urease, catalase, and phosphatase), and maize grain yield. The results showed that mean SOC, total N, biological activities, and maize grain yields were affected significantly (p < 0.05) by tillage methods. Compared with SS, 2RT, and 2RTSS, ZT had higher SOC, total N, soil bacteria, and soil actinomycetes in the 0–40 cm soil depth. The highest levels of fungi, urease, catalase, and phosphatase were recorded under SS in the 0–40 cm soil depth. Average maize grain yield of 7.37 ton/ha (9.81%) was recorded under SS compared to under ZT. Overall, we conclude that SS could be adopted as a promising soil management method for soil health, quality, and productivity resulting in a sustainable agricultural system.
