Spatial variability in soybean associated with soil fertility variations in a no-tillage system
Australian Journal of Crop Science
Understanding the spatial variability of soil fertility is necessary for preventing nutrient losses or excessive agricultural inputs. The aim of this research was to evaluate the spatial variability of the chemical characteristics of a Typic Hapludox cultivated with soybean for 110 days at different depths and the impacts of these characteristics on crop yield. Soil samples were collected at a total of 80 points in an area of 5000 m2 . The contents of P, Ca, Mg, S, Cu, Fe, Zn and Mn weredoi:10.21475/ajcs.20.14.09.p2551 fatcat:wij57ea43jdq5gjyh6wpiykyeq
