WINTER 2007 Fluid Journal 23 applications of Cl immediately after planting, usually in combination with N solution. However, recent studies have also shown that placement of the same rates beside the row at planting is effective and occasionally more effective than broadcast applications. The compatibility of ammonium chloride solutions with N, P, S and other fluid starter nutrients makes this an attractive means of Cl application when no other nutrient applications are planned. Grain sorghum. Grain sorghum yield responses to 20 lbs Cl/A on low Cl soils ranged from 4-18 bu/A over 8 locations for an average of 11 bu/A and an average increased return of $25/A. Increasing the Cl rate to 40 lbs/A produced small additional increases in some cases in Kansas State University studies (Table 1). Corn. Corn yield responses to 20 lbs/A Cl applications on low Cl soils ranged from 4-19 bu/A (average 10 bu/A) with a few additional increases to an additional 20 lbs/A Cl. Returns to the initial 20 lbs Cl on the average were $27/A in these Kansas studies (Table 2). Summary In the final analysis, Cl fertilization based on soil testing is an inexpensive way of boosting crop yields, lowering production costs per bushel and increasing grower profitability. Application rates around 20 lbs Cl/A seem to be optimal in most cases. Returns vary with crop, yield level, and prices but are in the $9-$27/A range for wheat, grain sorghum, and corn.
