Seasonal no-tillage ridge cropping system: a multiple objective tillage system for hilly land management in South China

The large area of hilly land in the southern regions of the Yangtze river is an important agricultural region in China. In this area, the land has been overexploited for many years due to heavy population with high deamand for food supply. Soil erosion, soil ferltility degeneration, and land productivity decrease are severe problems in this region. Seasonal No-Tillage Ridge Cropping System (SNTRCS), a multiple objective tillage system for hilly land management, was developed to address these problems in the Sichuan Basin of south China.
