Fertilizer is one of the most important, and most expensive, inputs on the farm every year. Achieving crop yield and quality goals involves providing the required nutrients needed to reach its full potential. The amount of nutrients needed to meet these goals changes by crop, field, location in the field and environmental conditions. To maximize uptake of nutrients by the crop, proper placement of fertilizer is a key part of the planting process.
When discussing the various methods of fertilizer application may different factors are taken into consideration including logistics required. In all cases, it is important to adhere to the main fertilizer application principles commonly referred to as 4R nutrient stewardship (right source, right rate, right place, right time).
