Management zones based on corn yield and soil physical attributes

Agronomía Colombiana, 2015
The need to increase the yield and thus the income of farmers and provide food for the growing population requires the search for more efficient and innovative ways for growing, such as management by zones or site-specific practices. This knowledge improves the process of decision making in agricultural production for better crop management. The aim of
