                Agro- climatic zones of India          The country has been divided into 15 agro climatic regions according to homogeneity in agro-characteristics such as soil , topography , rainfall , temperature , cropping and farming systems and water resources . 1. Western Himalayan Region:          It consists of three sub zones         1- Jammu and Kashmir         2- Himachal Pradesh         3- Uttarpradesh Hills  Himalaya Region consists of skeletal soils of cold region , mountain meadow soils ,podsolic soils and hilly brown soils . They have steep slopes , undulating terrain,silty loam type soil .This region is more prone to erosion hazards and slips and slides . Crops like rice , maize , millets , wheat and barley are grown here but productivity level is lower than that of the all Indian average . Highest area under forest is fo nd in this region . 2. Eastern Himalayan Region:  This region have high rainfall and high forest cover .   Arunachal Pr

Soil structure:-  The arrangement of primary particles (sand ,silt,clay), secondary particles ,and voids into definite patterns under certain field conditions. It  denotes How the particles and aggregates are arranged , their shapes and sizes . How the voids and spaces are arranged , their shapes and sizes . Importance of soil structure :- The amount and nature of porosity in soil are influenced by it . Water and air permeability into soil is governed by it . It influences soil water relationship , growth of microorganisms ,water holding capacity ,soil drainage and availablity of plant nutrients . Management of soil structure:- Management of soil structure leads to improvement of soil structure . The general principles are :- To ensure least destruction of soil structure the tillage should be done at optimum moisture conditions . To minimize the loss of aggregate stabilizing organic substances minimum tillage should be done. To mitigate the beatin
