Deccan plateau

Deccan plateau represents Karnataka Plateau and Anantapur of Andhra Pradesh covering an
area of 4.9 m ha. The soils are represented by gently sloping shallow and medium red loamy
(Rhodustalfs, Haplustalfs, Ustropepts) and level to very gently sloping, deep, clayey black
soils (Pellusterts and Ustropepts). The common post-rainy season crops are sorghum and
safflower whereas groundnut, sunflower, sugarcane and cotton are intensively grown under
irrigated conditions wherever feasible. In this region, the extent of Zn deficiency was
highest (34.9%), followed by Fe (21.5%) and B (10.4%). The deficiencies of Cu (2.7%) and
Mn (1.5%) were negligible.

Northern Plain including Aravallis

This AER includes Aravallis, hot semi-arid ecoregion covering an area of 32.3 m ha, that
represents 9.8 per cent of the total geographical area of the country. It is further divided
into North Punjab Plain (4.1), North Gujarat Plain (4.2), Ganga Yamuna Doab (4.3) and
Madhya Bharat Plain (4.4) AERs. The climate of the AER is characterized by hot and dry
summer and cool winter with coarse to fine loamy soil types. Almost 65 per cent of the region
is under irrigated agriculture and intensively cultivated involving both karif and rabi crops,
such as rice, millets, maize, pulses, berseem, wheat, mustard and sugarcane. Highest
deficiency of Zn is recorded in the area of Madhya Bharat Plateau and Bundelkhand uplands
