Tillage effects on the aggregation of a clayey Red-Yellow Podzolic soil in Lavras, Minas Gerais State, Brazil



Tillage effects on the aggregation of a clayey Red-Yellow Podzolic soil in Lavras, Minas Gerais State, Brazil



Revista Brasileira de Ciencia do Solo 7(3): 317-322



The effect of tillage on soil aggregation was studied on a Red-Yellow Podzolic soil in Minas Gerais, Brazil. Samples of three profiles under natural pasture and three profiles under maize and rice cultivation for more than ten years were analysed for particle size distribution, water-dispersible clay, free iron oxides, organic matter, macroporosity and microporosity.
