Effect of management systems in soil chemical attributes

, 2007
Soil chemical attibutes were assessed after nine years on a typical Dystrophic Red Latosol located in Passo Fundo, State of Rio Grande do Sul, Brazil. Four soil management systems – 1) no-tillage, 2) minimum tillage, 3) conventional tillage using a disk plow followed by use of a disk harrow, and 4) conventional tillage using a moldboard plow followed ...
