Estimation of plant N,P and K contents in the Inner Mongolia steppe using SPAD value

摘要：

For the last few decades, the Inner Mongolia steppe has been degraded by improper use.As a result, the productivity of grasses and livestock in the steppe has decreased dramatically.Understanding the current state of desertification and the dynamics of degradation of the steppe located at the center of Eurasia is essential for protecting and restructuring this land effectively.A simple and rapid method to evaluate the composition of grasses growing in the steppe is needed.The possibility of estimating N, P and K content of the plants using the SPAD ( Soil & Plant Analyzer Development) value was examined in the present study.
