Abstract

Organic matter application and water management were frequently applied to prevent the oxidation of pyrite in acid sulfate soils. The purpose of this study was to determine the effect of cow manure application with varying height of inundation on soil pH, soluble-Fe, and available P of acid sulfate soils. This study employed factorial treatments and in a completely randomized design. The first factor was the dosage of cow manure: 0, 10, and 20 t ha-1, while the second factor was various water depths: 5, 10, and 15 cm. Results of study showed that the interaction of cow manure and water depth did not affect soil pH, but single factor of the treatments (cow manure and water depth) significantly affected soil pH. The interaction of cow manure and water depths did not significantly decrease the solubel-Fe in the fourth week. The interaction of cow manure and water depths significantly increased P-availability in the fourth week. Results of this study demonstrated that cow manure application and water depth improved soil pH and P-availability of acid sulfate soils.

Abstract

Background: Swamps are ecologically important ecosystems in the biogeochemical cycle and are one of the targets of land conversion for food estate development. Objective: This study aims to examine the impact of the minipolder system on soil organic carbon (SOC) stocks in the Food Estate area of Sambang Lihumm Banjar Regency, South Kalimantan. Methods: Soil sampling was conducted using a purposive sampling method in natural swamp (control) and tukungan plots (maize cultivation). The soil samples consisting of intact and disturbed were collected, with parameters analyzed including soil moisture content (gravimetric method), bulk density (gravimetric method), and %C-organic (Walkley and Black method). Results: The result of study showed that conversion of swamp to dry land agriculture reduced soil moisture content, while bulk density increased from 0.78 gram/cm3 to 1.19 gram/cm3. Furthermore, SCO stocks averaged 35.00 ton/ha in natural swamp and 37.73 ton/ha in tukungan. Conclusions: The conclusion of study is that the increased bulk density and accumulation of topsoil in tukungan contributed to higher soil organic carbon (SOC) stocks.
