Sub-surface placement of nutrients is a best management practice (BMP) in an effort to reduce off-site transport of P and N. There is variety of placement techniques and equipment which becomes important information as farmers decide a solution or suite of solutions to adopt. Frequently, it is unclear which types of implements are best suited to meet the nutrient management goals for a farm operation. Equipment capable of sub-surface placement can vary in horsepower requirements, placement options, and the level of surface disturbance. The “right” implement will vary from farm-to-farm based on the differing management strategies.
An Ohio State University Fact Sheet (Opportunities for Sub-surface Nutrient Placement in Ohio) has been developed to help review and understand specification of different implements for sub-surface placement of fertilizers. This publication can be accessed at https://ohioline.osu.edu/factsheet/fabe-56401. To help identify which implement(s) is best suited for your farm, the Ohio State Precision Ag Team compiled a list of sub-surface placement benefits and categorized available equipment options.
