The Effect of Phosphate Enhanced Organic Matter on Fertility and Productivity of Latosol Soil, Bogor Regency

Abstract

P fertilization and application of organic matter are some of the efforts to increase the P availability in the soil. The application of organic matter enriched with phosphate fertilizer increases the P-available in soil. This study therefore aims to determine the effect of applying organic matter enriched with phosphate fertilizer on several chemical properties as well as productivity of lowland rice fields in Bogor Regency. The study was conducted by UNB’s greenhouse and paddy fields in Darmaga, Kemang and Sukaraja Districts, Bogor Regency. Organic material in the form of cow dung with a dose of five levels was enriched with phosphate fertilizer in the form of H3PO4 in an equal dose, and incubated for 30 days. Subsequently, the phosphate enriched mixture with the best incubation result for fertility level was applied in the paddy fields. The results showed about 60 tons / ha of organic matter 225ppm P of Posfat fertilizer had optimum fertility after 30 days incubation, followed by 40 tons / ha of organic, enriched with the same dose of phosphate fertilizer. In addition, Latosol soil, Bogor Regency, where organic matter enriched with about 225ppm P of phosphate fertilizer in all locations had the same soil fertility and lowland rice productivity, meaning no significant difference was obtained using the same dosage of organic matter. Meanwhile, soil fertility in the form of pH, available CEC and P increased, as well as lowland rice productivity, increased with the application of organic matter (60 tons / ha).

Effect of mulching on soil loss and total N through erosion during upland rice planting season on latosol

“…be a source of energy for micro-organisms [2]. Furthermore, it is said that in improving the state of nutrients, organic matter added to the soil will mainly supply nitrogen, sulfur and phosphate for plants [3]. Organic matter added to the soil in the form of green manure, manure and compost will also resist runoff and reduce soil erosion.…”

Assessing the Effects of Rice Land Function Transfer on Farmer Quality of Life

“…According to information from the Agricultural Training Center I Parung Panjang Region (2021) [5], 4 out of 11 villages have experienced a significant conversion of agricultural land into housing, namely Jagabita, Lumpang, Cikuda, and Cibunar Villages. The average land in Bogor Regency is quite productive and fertile with organic fertilizers by farmers that contain sufficient pH, Cat-ion Exchange Capacity (CEC), and P to increase the productivity of paddy rice [6]. Several variables positively affect agricultural productivity, such as land productivity, total agricultural machine power, and conversion from agricultural land to built-up land [7].…”
