Stagnation and decline in productivity of most of the agricultural and plantation crops in Kerala, despite the genetic
improvements in crop varieties and heavy external inputs of fertilisers and pesticides, prompted the Kerala State
Planning Board to embark on a massive project to identify and map the soil related constraints to crop production.
Highly weathered laterite soils, covering most of the state, are relatively infertile, acidic, gravelly clay depleted of
basic cations and possessing low water and nutrient retention capacity. In order to assess the soil fertility in the state
and to elucidate the soil related constraints nearly two lakh composite surface soil samples were collected from
farmer’s fields all over the state and analysed for soil reaction, macro, secondary and micronutrients. Extensive
acidification of the soils, build up of high levels of phosphorus and deficiencies of calcium, magnesium and boron
were found to be the major soil related constraints in the state.
