ResetAt 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.
Fertility Programs for Reduced Irrigation and Population
As water well production slows and regulations increase in areas of heavy groundwater use,
growers are forced to cut back plant populations to match irrigation capacities.

The objective of this trial was to determine the effectiveness of foliar applied phosphorus on corn
yield.
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.

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
Alabama we compared R3 foliar applications on soybeans with a $40/A fertility budget.
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.
Field Evaluation of Supplemental Pre-Plant Sulphur Application in Soybeans
Sulphur is essential for protein formation, enzyme function, and efficient nitrogen fixation in soybean plants. Adequate sulphur availability helps promote healthy plant growth, improved nodulation, and strong seed development.
Crops: Soybean and Soybeans. States / Provinces: Ontario. Nutrients: Nitrogen and Sulfur. Years: 2025. Applications: Broadcast, Irrigation, Side Dress, and Topdress.
Field Evaluation of Supplemental Nutrient Applications at Sidedress in Grain Corn
Sidedressing nitrogen in corn allows nutrients to be applied closer to the time when the crop needs them most, improving nitrogen use efficiency and supporting strong plant growth during key development stages.
Crops: Corn. States / Provinces: Ontario. Nutrients: Nitrogen, Phosphorus, Phosphorus, Potassium, and Potassium. Years: 2025. Applications: Side Dress and Y-Drop.
A Field Evaluation of Dry vs. Liquid Fertilizer Placement in Strip-Tilled Grain Corn Production
Strip tillage combines the soil conservation benefits of no-till with the seedbed advantages of conventional tillage. By tilling narrow planting strips while leaving the rest of the field undisturbed, strip tillage reduces erosion, improves soil structure, and retains moisture.
Crops: Corn. States / Provinces: Ontario. Nutrients: Micronutrients, Nitrogen, Phosphorus, Phosphorus, Potassium, and Potassium. Years: 2025. Applications: Strip-Till.
Field Evaluation of Supplemental Foliar Phosphorus Applications in Grain Corn
Phosphorus plays a critical role in early corn plant development, energy
transfer, and root growth. It is a key component of adenosine triphosphate
(ATP), which drives many metabolic processes required for plant growth.
Field Evaluation of Pre-Plant Nitrogen and Sulphur Fertilization in Winter Rye
Nitrogen and sulphur are two essential nutrients for winter rye. Nitrogen is
a key component of chlorophyll and proteins, making it vital for
photosynthesis, vegetative growth, and overall biomass production.
Response of Winter Canola to Supplemental Sulphur Fertilization Under Field Conditions
Winter canola has a high demand for sulphur during growth and seed
formation.
Field Evaluation of Supplemental Foliar Phosphorus Applications in Grain Corn
Phosphorus plays a critical role in early corn plant development, energy
transfer, and root growth.
2×2 Fertilizer Economic Challenge in Corn
In 2025 we did economic challenge plots with XtremeAg to see how three growers from different

Field Evaluation of Supplemental Nutrient Applications at Sidedress in Grain Corn
Sidedressing nitrogen in corn allows nutrients to be applied closer to the
time when the crop needs them most, improving nitrogen use efficiency
and supporting strong plant growth during key development stages.
Applying nitrogen during the growing season can reduce the risk of
nutrient losses from leaching or runoff.
A Field Evaluation of Dry vs. Liquid Fertilizer Placement in Strip-Tilled Grain Corn Production
Strip tillage combines the soil conservation benefits of no-till with the
seedbed advantages of conventional tillage. By tilling narrow planting
strips while leaving the rest of the field undisturbed, strip tillage reduces
erosion, improves soil structure, and retains moisture.

Response of Winter Canola to Supplemental Sulphur Fertilization Under Field Conditions
Winter canola has a high demand for sulphur during growth and seed

and the production of important compounds that influence oil quality.
Citrus Trial Weight and Gross Income
The objective of this trial was to compare the grower standard program to AgroLiquid program that has replaced the phosphorus and potassium in the grower standard program with AgroLiquid products of PrG for the phosphorus and Kalibrate for the potassium.
