Abstract

Water management is main factor that determines the successful of rice cultivation in acid sulphate soil. Soil waterlogging determines the direction and rate of chemical, geochemical and biological reaction in the soil, indirectly these reactions may influence to the changes of soil psycal properties during soil waterlogging process. The experiment was aimed to study the changes of two type of acid sulphate soils physical properties during rice straw decomposition processes. The research was conducted in the greenhouse consisting of the three treatment factors using the completely randomized design with three replications. The first factor was soil type: potential acid sulphate soil (PASS) and actual acid sulphate soil (AASS). The second factor was height of water waterlogging: 0.5-1.0 cm (muddy water–level condition) and 4.0 cm from above the soil surface (waterlogged). The third factor was organic matter type: rice straw (RS), purun tikus (Eleocharis dulcis) (PT) and mixed of RS and PT (MX). Soil physical properties such as aggregate stability, total soil porosity, soil permeability, soil particle density and bulk density were observed at the end of experiment (vegetative maximum stage). The results showed that acid sulphate soil type had large effect on soil physicl properties, soil waterlogging decreased aggregate stability, soil particle density and bulk density both of soil type.Keywords : Acid sulphate soils, soil physical properties, and waterlogging [How to Cite: Arifin F, A Susilawati and A Rachman. 2014.

Highlights

Precision farming systems are an agricultural management technology which basically aims to generate sustainable agricultural production and it is about the farm management techniques which are based on a specific spatial variability of land characteristics including soil nutrients content, temperature regime, water, and crop requirement in the field
The purpose of precision farming system is to integrate the use of land resources characteristics and crop requirements by the agronomic practices due to variability of land characteristics for every place and time (McBratney and Pringle 1997)
Precision farming system requires three main components namely: (a) global positioning system (GPS) to determine precisely where the position of the samples, (b) proper time mechanism for controlling nutrients, pesticides, soil moisture and other production inputs, and (c) a database that provides information is needed to develop an appropriate package of inputs for various site specific conditions (Camberdella and Karlen 1999)

Summary

Introduction

Precision farming systems are an agricultural management technology which basically aims to generate sustainable agricultural production and it is about the farm management techniques which are based on a specific spatial variability of land characteristics including soil nutrients content, temperature regime, water, and crop requirement in the field. Voltz (1997) stated that appropriate farming systems required accurate information about the land characteristics in detailed and land management to implement specific land treatment. Precision farming system requires three main components namely: (a) global positioning system (GPS) to determine precisely where the position of the samples, (b) proper time mechanism for controlling nutrients, pesticides, soil moisture and other production inputs, and (c) a database that provides information is needed to develop an appropriate package of inputs for various site specific conditions (Camberdella and Karlen 1999). An integrated approach of the agricultural process starts from the planning of soil tillage, planting, use of fertilizers and pesticides, harvesting and post-harvest processes
