Soil Testing and Nutrients Application

and Recommendations

Soil test results can indicate the potential for a positive crop response to fertilizer application. The soil test must be appropriately calibrated and accurately interpreted for the specific crop to determine the appropriate fertilizer amount.

Additionally, soil properties can vary significantly within a field. Factors such as soil texture, organic matter content, pH, and nutrient levels influence soil cation exchange capacity (CEC) and can differ widely across field areas.

This common knowledge has led to Variable Rate Technology (VRT). This practice was thought to reduce the overall nutrient application, which likely will help growers adjust inputs based on soil properties, increase their yield, and benefit the environment.

To achieve optimal and integrated soil fertility, we have developed interactive Excel sheets that take into account all factors, including the nutrient carryover capacity of prior fertilizer applications, thus facilitating suitable fertilizer recommendations for your corn, soybean, and wheat. The primary aim is to assess the long-term spatial and temporal variability of nutrients related to fertilization programs, balance soil nutrient dynamics utilizing soil test data to establish cost-effective fertilizer application rates, enhance crops' economic returns, and bolster soil conditions' resilience.
