The use of soil test variability in precision agriculture studies is well known. However, little is known about the spatial variability of the plant nutrient concentration, specially in a no-tillage system. The nutrient concentrations in plants reflect its real availability in the soil. In a no-till farm in southern Brazil, two growing seasons of soybean were sampled to evaluate the spatial variability of plant nutrient concentrations; and to identify the constraints to soybean yield… Expand
