Explain any three factors responsible for land degradation in India.

Explanation

(i) A large tract of agricultural land has lost its fertility due to alkalisation and salinisation of soils and waterlogging.
(ii) Excessive use of chemicals such as insecticides and pesticides has led to their concentration in toxic amounts in the soil profile.
(iii) Leguminous crops have been displaced from the cropping pattern in the irrigated areas and duration of fallow has substantially reduced owing to multiple cropping.
