China LTFE Network - Gongzhuling
This experiment has been added by the GLTEN Curators using existing published sources.
- Objective
- To assess the sustainability of agricultural systems including: 1. whether acceptable crop yields can be maintained over a long period, 2. the nutrient inputs required to maintain crop yields and soil reserves of nutrients 3. understand costs of nutrient losses
- Description
- This experiment is part of the China National Soil Fertility and Fertilizer Efficiency Long-term Monitor Network which aims to address problems around sustainability of agricultural systems by studying cropping systems across nine highly diverse regions of China. The experiments represent approximately 86 Mha of arable land in China and are relevant to large areas in other parts of Asia and elsewhere.
