Abstract

A comprehensive study was undertaken to assess soil and water quality of three different farming areas in Trichur and
Ernakulam districts of Kerala during traditional paddy cultivation period from June to December 2000 and the extensive
shrimp culture season from January to April 2001. Studies revealed that organic carbon in soil was higher during Pokkali
paddy crop vis a vis extensive shrimp culture. Soil was acidic during both the crops. There was no difference in other soil
parameters such as electrical conductivity and redox potential. Water parameters like salinity, ammonia and nitrite values
were marginally higher during extensive shrimp culture than during paddy crop. However, pH, chemical oxygen demand,
phosphates and total phosphorous were not different between the two crops. The soil and water parameters, except soil pH,
were observed to be within optimum range for shrimp farming
