Soil chemical indicators and nutrient cycling variations across sequential years of rice cultivation: A case study of floodplain conditions of the Amazon, Brazil

To meet the rising food demand for next generations, soils are needed to stand biological yield and promote animal, plant and human welfare. In this logic, the aim of the study was to determine the effects of different soil uses; (a) successive irrigated rice planting and (b) different soil management practices onto soil chemical properties and nutrient cycling. The study was carried out in areas with dissimilar years...
