Fertilisers and organic manures are vital ingredients for sustainable growth of Indian agriculture. The role of mechanization in timeliness of various farm operations, saving of agriculture inputs, enhancing the cropping intensity, drudgery reduction, reduction of environmental degradation, increase in gross income and returns to the farmers is well documented. In India, application of granular fertilisers is accomplished mostly by manual broadcasting and mixing in top soil with enormously low nutrient use efficiency. Seed-cum-fertiliser drills and planters being used in irrigated area to place fertilisers at shallow depths to the side of seeds with improved utilization. Development and adoption of technologies for placement of fertilisers and manures deeply in the moist root zone is of paramount significance to cut down the expenditures on this precious input. In light of these concerns, this article presents the present State-of-the-Art of fertiliser application technology and advances made towards deep placement with improved top and subsoil health management in context of Indian agriculture.
