This chapter proposes that the way forward will be a prosperous and sustainable agriculture sector deeply rooted in the concept of sustainable intensification (SI): producing more with less, using inputs like seeds, fertilizers, and pesticides more prudently, adapting to climate change, reducing GHG emissions, improving natural capital such as soil moisture capacity and the diversity of pests' enemies, and building resilience. One approach to SI is to employ precision agriculture, ensuring that inputs—whether nutrients, pesticides, seeds, or water—are used in a precise, sparing, effective, and strategic way in order to minimize their environmental impact. Thus microdosing permits the prudent, targeted use of inputs such as fertilizers, thereby improving soil quality and moisture while reducing the environmental impact that excessive use can cause. It also reduces costs and helps improve nutrient use efficiency and protection against drought. Precision farming focuses on just one aspect of SI. More generally, it is a concept that includes three mutually reinforcing pillars: ecological intensification, genetic intensification, and socioeconomic intensification.

Since the Green Revolution era, the farming sector exploited the soils for food, fiber, fodder, etc., with high input responsive varieties that excavated vast amounts of chemical fertilizers. The burgeoning population of the country calls for a commensurate increase in food production to satisfy the demands of its inhabitants. Further, due to innovative mechanization in agriculture, specialization, and government policy programs, the productivity of food has soared. Subsequently, it ensued greater productions and minimized food prizes. Regrettably, intensive agricultural operations degraded the soil quality and now reached such a stage where without external inputs, growers unable to achieve their targeted yields. India has lost 68% innate productive capacity of agricultural soils. This plunder of land’s quality continues unabated, further resulting in low nutrient use efficiency and insufficient yields of agroecosystems. Therefore, this is high time to realize the dreadful impacts of intensive crop production on the natural ecosystem. Irrefutably, both soil and its nutrients are the wondrous gifts of nature to humankind; utilizing them sustainably is imperative. The present chapter highlights the impacts of non-judicious nutrient management on soil productivity, nutrient use efficiency, and novel technologies required to promote sustainable agriculture and achieve the target of doubling farmer’s income in India.

Grafting, a surgical technique to attach genetically different shoots and roots (scions and rootstocks) allows “designer root systems” to enhance agricultural productivity and sustainability. Rootstocks improve plant nutrient relations by increasing nutrient capture and/or nutrient use efficiency, by multiple mechanisms including altered root morphology. Moreover, rootstocks can enhance water uptake and/or diminish water loss according to changes in root form and function, and root-to-shoot phytohormonal signalling. While the role of root-to-shoot ABA signalling in effecting stomatal closure is equivocal, root-sourced cytokinins and ACC regulate shoot senescence and vegetative growth respectively. Rootstock-mediated crop improvement offers opportunities to enhance crop resource use efficiency, especially in the developing world.
