The soils used to grow irrigated rice in the State of Santa Catarina have different mineralogical and chemical characteristics from the soils used for calibration studies of the Mehlich-1 extractant, for estimating soil phosphorus availability to plants. Thus, the aim of this study was to evaluate the effectiveness of Mehlich-1, Mehlich-3, Resin, Olsen and EDTA extractants in predicting P availability to flood irrigated rice in soils of State of Santa Catarina. The experiment was carried out in a greenhouse in […]
