Evaluation of corn production parameters and their spatial relationship with chemical attributes of the soil

The characterization of the soil spatial variability allows a better understanding of the relationships between the soil attributes and the environment. The objective of the study was to evaluate the spatial variability of corn production parameters and their relationship with soil chemical attribut...
