Abstract

The semi-coastal areas of the Vietnamese Mekong Delta are suited to the rice/shrimp farming system which utilizes the wet season to cultivate rice and the dry season to produce shrimp when fresh water is scarce and the canal systems carry saline water. The production system has high inherent risk with both rice and shrimp enterprises failing due to climatic events. As such, farmers seeking to increase profitability and resilience to losses aim to decrease costs of production. Fertiliser costs are a significant percentage of the cost of rice production whilst shrimp production produces biological waste sludge which settles at the bottom of ditches surrounding and within the rice field. A controlled environment experiment was conducted to determine the mineralisation potential of this sludge. The fertiliser value of this sludge was then evaluated in the field over two seasons at two locations on rice/shrimp farmers in Vietnam.
