5.1 Decreasing Soil Fertility Impact on Agriculture
With population boon and rapid urbanization and industrialization, there is a need
for enhancing agriculture productivity on shrinking agricultural land
(Balasubramanian and Choi 2010; Chen et al. 2011; Agarwal et al. 2015). Healthy
soil is the foremost and crucial element for sustainable agriculture and crop productivity which rely on efficient nutrient and water cycling. Soil health is dependent on
physical (soil texture, water-holding capacity, moisture content, soil temperature,
etc.), chemical (pH, redox potential, minerals, organic matter, cation exchange
capacity, etc.), and biological (physicochemical properties of soil, organic matter,
and rhizosphere biota) characteristics (Kibblewhite et al. 2008; Frac et al. 2018;
Meena et al. 2019; Yu et al. 2019). But contrary to it, injudicious and heavy application of agrochemicals in the past few decades adversely affected soil structure, soil
chemistry, and most importantly soil biota (Amundson et al. 2015; Datta et al. 2016;
Gouda et al. 2018). Soil health not only plays a crucial role in crop productivity but
also maintains soil biota, reduces carbon footprint through carbon sequestration,
