At AgroLiquid, we study a variety of crops in detail to determine the best fertilizer combinations. All of our fertilizer research is carefully documented, including what fertilizers we use, when, on what crops, and how those crops grow. Much of our research is conducted at our 1,000 acre research facility, the North Central Research Station (NCRS). We also partner with farmers, growers, and ranchers across the country to conduct fertilizer research in other climates and soil types. This helps us perfect our fertilizer programs, and develop the most efficient combinations for all types of crops.

2×2 Fertilizer Economic Challenge in Soybeans

In 2025 we did economic challenge plots with XtremeAg to see how three growers from different
parts of the country build a fertility program using a set application method and budget. In
Tennessee we compared foliar applications on wheat with a $30/A fertility budget.

Crops: Soybean and Soybeans. States / Provinces: Iowa, Maryland, and Tennessee. Nutrients: Calcium, Fulvic, Micronutrients, Multinutrient, Nitrogen, Phosphorus, Phosphorus, Potassium, Potassium, and Sulfur. Years: 2025. Applications: Foliar.

2×2 Fertilizer Economic Challenge in Soybeans

In 2025 we did economic challenge plots with XtremeAg to see how three growers from different
parts of the country build a fertility program using a set application method and budget. In
Arkansas we compared foliar applications on cotton with a $50/A fertility budget.

Crops: Soybean and Soybeans. States / Provinces: Arkansas, Iowa, and North Carolina. Nutrients: Calcium, Fulvic, Micronutrients, Multinutrient, Nitrogen, and Potassium. Years: 2025. Applications: Foliar.

2×2 Fertilizer Economic Challenge in Corn

In 2025 we did economic challenge plots with XtremeAg to see how three growers from different
parts of the country build a fertility program using a set application method and budget.

Crops: Corn. States / Provinces: Arkansas, Iowa, and Tennessee. Nutrients: Calcium, Fulvic, Micronutrients, Nitrogen, and Sulfur. Years: 2025. Applications: Broadcast, Foliar, In-furrow, Planter, Side Dress, and Topdress.

Nutrient Effects on Nitrogen Utilization

This trial tested the relationship between a nitrogen application in conjunction with Micro 1000 (10 micro and secondary nutrient package) and LiberateCa (calcium).

Crops: Corn. States / Provinces: Iowa. Nutrients: Calcium, Micronutrients, and Nitrogen. Years: 2024. Applications: Planter and Planting.

Foliar Potassium on Soybeans – XtremeAg

This trial was established to compare AgroLiquid’s foliar potassium products Sure-K and Kapitalize to the grower standard application of potassium acetate.

Additionally, costs analysis was completed looking at yield revenue minus the cost of product.

Crops: Soybean and Soybeans. States / Provinces: Iowa. Nutrients: Potassium. Years: 2023. Applications: Foliar.

Additionally, costs analysis was completed looking at yield revenue minus the cost of product.

Crops: Corn. States / Provinces: Iowa. Nutrients: Potassium. Years: 2023. Applications: Foliar.

XtremeAg Trials Report 2021

XtremeAg is very transparent with what they do on their farms and will highlight products and practices that work, along with those that don’t. AgroLiquid has used this opportunity to test out-of-the-box ideas, push for high yields, and expand testing on crops we have little data on.

This report includes the results for 2021 for each of the locations where testing was done.

Crops: Corn, Cotton, and Soybeans. States / Provinces: Alabama, Arkansas, and Iowa. Nutrients: Programs. Years: 2021. Applications: Foliar, Irrigation, Planter, and Planting.
