Renovation Of Acid Sulfate Soil For Integrated Farming At Delta Berbak, Jambi Province

Abstract

Deltat Berbak is one of transmigration areas developed in pentland located in Jambi Province, Indonesia. In the earIy stage of reclamation, rice production reached 5 tons/ha, but gradually decreased thereafter to a production of less than I ton/ha. Nowdays, some farmer are still continuing rice cultivation with low production, while some others abandoned their lands. For improvement of rice production, we used a technological package of acid sulfate soil management that consists of managing canal water; increasing pH of soil and water by liming, fertilization of macro-nutrients containing N, P, K, and Mg and micro-nutrients such as Fe, Cu, Zn through foliar application. With this technological package we got unhulled rice yield of more than 4 tons/ha. For improving people welfare significantly development of single crop of such as rice is not adequate. Alternatively, crops integrated farming that cultivates multiple diverse such as rice, horticulture, plantation as well as animal husbandry and fishery simultaneously is more seceru for increasing farmer income.
