Long-term Cultivation and Fertilizer Changes Soil Chemicals

Abstract

This paper briefly summarizes the effects of long-term cultivation and fertilizer on soil chemistry in recent years. The effects of different topography, long- term fertilization, different farming patterns, and different drainage modes on the dynamic changes of soil pH, large amounts of elements (effective phosphorus, quick- impact potassium), and medium and small elements (exchangeable calcium, magnesium) were mainly introduced and discussed. Due to the misuse of chemical fertilizers and pesticides in recent years, the phenomenon of soil chemistry has become increasingly serious. Only by comprehensively analyzing the effects of farmland management measures on soil chemistry and understanding the changing laws of soil chemical quality can sustainable agriculture and eco-friendly agriculture be better developed.
