Buckwheat fertilizer guidelines



Phosphate and potash

Guidelines for using phosphate and potash are summarized below.

These fertilizers, when needed, should be broadcast and incorporated before planting. Special sources of phosphate and potash are not needed for buckwheat production. All commonly sold sources for each nutrient are equal.

There is no research that suggests nutrients other than N, P and K are needed in a fertilizer program for buckwheat production in Minnesota.
