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. This book presents details description of the design procedure of the equipment and the response of sugarcane crop to differential rate fertilizer...
