Nutrients deficiency is the main problem restricting the development of agriculturepreduction. Increasing the amount of manure is impossible
and the area of Leguminous cropsdeclines increasingly.The key measures to solve the problem of fertilizer input are raising chemi-cal fertilizer application
applying nitrogen and phosphorous fertilizer at a proper ratio and in-creasing fertilizer use efficiency
