India is the home of 130 million people, and feeding this ever increasing population is an arduous task for the farming community. To satisfy the hungry stomachs and minimize the yield gap, there must be a continuous flow of inputs especially high-analysis fertilizers. After nitrogen, phosphorus (P) is the most yield-limiting nutrient having use efficiency of <20% in tropical soils. Due to several reasons, India heavily relies on foreign countries for P-fertilizers which put enormous pressure on our foreign reserves. Hence, avenues should look for the use of unconventional raw materials for production of P-fertilizers or can be directly used for supplying P to the crops. India with highest number of livestock population and by-products or wastes from this sectors like (blood, bone and rumen) can be wisely used for production of P-fertilizers which is economical and environment friendly. Therefore, in this article, the possibilities and bottlenecks for utilization of slaughterhouse are discussed especially where the country lacks high-quality rock phosphate ore.
