Abstract

The aim of this study is to analyze the types of clay minerals using x-ray diffraction (XRD) in several different locations in Yogyakarta, especially in paddy fields that have different types of soil management. The results of clay mineral analysis using XRD showed that the tillage layer on the paddy field in the Minggir sub-district, Sleman contains clay minerals of type 1:1, namely the type of Metahaloisite (Al2Si2O5(OH)4). While the results of the analysis of clay minerals in the top layer of paddy soil in Nanggulan sub-district, Kulonprogo and Pundong sub-district, Bantul showed a clay mineral of type 2:1 type Montmorillonite, where the Montmorillonite clay mineral contained in paddy soil in Nanggulan sub-district, Kulonprogo, had mineral crystallization higher better than the Montmorillonite clay mineral in the Pundong sub-district, Bantul.Keywords ：x-ray diffraction (XRD),clay minerals, paddy fields

Abstract

This study aims to examine the availability of soil organic C, availability of ammonium and the dynamic pattern of organic C in organically managed paddy soils for 8 to 10 years at three different lowland rice locations in Yogyakarta. The research was conducted using survey techniques and descriptive methods. The results showed that paddy fields that were given organic fertilizer for 8-10 years had higher organic C than non-organic paddy fields, namely an average of 2.10-2.70%. In organically managed paddy soils also showed a significant positive relationship between soil organic C and NH4+-dd in MS paddy soils containing clay minerals 1:1 (r= 0.71) and NK paddy soils (r= 0 .64) and PB (r= 0.77) which were dominated by clay minerals 2:1. The correlation was not significant in the non-organic managed paddy fields. Keywords ：paddy soils, organic C,NH4+-dd
