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.
