摘要: ABSTRACT The overloading of soil with manure or mineral fertilizers enhances phosphorus (P) availability, promoting its loss to water bodies and increasing the risk eutrophication. In this sense, establishment an environmental P threshold is a simple useful tool classify soils regards losses. Here we propose P-threshold for from state Rio Grande do Sul (RS) in Brazil, clay content as principal variable [...]
