Broadcasting of fertilizer leads to the loss of 30 - 40% of nutrients though surface runoff. Band placement of fertilizer in root zone increases the nutrient uptake by plants thereby increasing fertilizer use efficiency. The Subsoiler-cum-Differential Rate Fertilizer Applicator designed in this research work, applies fertilizer in differential manner in vertical root profile of crop. Performing two operations in one pass it also saves energy.
