Measuring the Success of Sure-K

Agronomic Adviser logo

Soybean fertility programs have long been a focus of AgroLiquid’s crop nutrient research.

Sure-K is one of AgroLiquid’s flagship products. Many years of research, as well as grower experience, have proven its performance.

Knowing that soybeans utilize a lot of potassium and understanding the low soil potassium (K) levels in many parts of the soybean growing areas, Sure-K was a perfect fit for a soybean fertility program. In the late 1990’s the North Central Research Station (NCRS) began testing Sure-K as a foliar application on soybeans. These foliar applications are especially beneficial, as they can be made in conjunction with most post-emergence pesticide applications.

Since 1998, 165 comparisons have been completed across the US. This data helps us determine both the yield and economic benefit of a soybean foliar fertility programs. As shown in the data below, over these 24 years Sure-K has provided a positive yield return 90% of the time with an average yield increase of 4.5 bu/A, returning an average of more than $22/A for the fertilizer dollars invested.
