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.

Little has been recorded regarding field chloride variability. Although most Northern Plains producers soil sample for NO3-N, chloride is an important component of sampling. Current sampling guidelines for composite soil sampling may overestimate the amount of nutrient sin a field, leading to under-fertilization of nutrients, including chloride. Read more

Addressing Soil Chloride Variability and Its Management, 1997 Four sites in North Dakota were selected in order to study chloride variability. This study has been conducted partially to investigate undocumented reports of chloride response in soils that test high in chloride, where no response was expected. The other purpose of this study was to determine the most appropriate soil sampling scheme for chloride.
