ANALISIS KANDUNGAN FOSFOR PADA TANAH SAWAH DAN BERAS DI DESA WOLOAU KECAMATAN MAUROLE KABUPATEN ENDE

Abstract

High phosphorus (P) content and continuous fertilization cause P saturation, nutrient imbalance in the soil, low efficiency, and the possibility of other nutrients such as Zn becomes unavailable. Therefore it is necessary to research to determine the content of phosphorus in rice fields and rice in Woloau Village, Maurole District, Ende Regency. This study uses a survey method, where the determination of soil samples done by a purposive method. With this method, three hamlets were obtained, which cultivated Ciherang and Inari rice varieties. The main variables observed were available P and total soil P, P in rice. The supporting variables are C-Organic and soil pH. C-Organic is a percentage of fertility in the soil consisting of various C (carbon) bonds. The soil pH is the acidity or basicity of an object measured on a pH scale between 0 to 14. The results of research this show that the mainstay of P is available in paddy soils, namely 96.49 ppm, 101.9 ppm, 97.99 ppm, 98.32 ppm, 95.01, and TC3 99.11 ppm with very high criteria. The total P content in paddy soil is 177.54 ppm, 208.39 ppm, 192.61 ppm, 163.21 ppm, 161.99 ppm, 175.92 ppm with very high criteria. The P content in rice is 1201.88 ppm, 1197.34 ppm, 1230.11 ppm, 1231.23 ppm, 1240.51 ppm, 1248.09 ppm.
