Addressing Soil Chloride Variability and Its Management

Addressing Soil Chloride Variability and Its Management, 1998 In the northern Great Plains, grid sampling is not used by many wheat producers because of its expense. To be profitable, responsive areas within fields (less than 30 lb Cl/A 2 ft) need to be characterized by a minimum number of soil samples. Five sites (Mandan, Valley City, Colfax, Gardner, and Hunter) in North Dakota were selected in order to study Cl variability. Each of these sites was sampled at small grid spacings.
