Abstract

Water and nutrients is important for plant which has its characteristics. This study has been carried out in the UB (Brawijaya University) forest about soil moisture content during rainy and dry seasons, Total-N, -P, -K from litter on different types of shade and age of coffee plants, and their effect on soil Available-N, -P, and -K. There are P1 (control), P2 (4-year-coffee + pine), P3 (7-year-coffee + pine), P4 (4-year-coffee + mahogany), and P5 (7-year-coffee + mahogany). These treatments affected to total soil moisture storage, Total-N, -P, -K of litter, and Available-N, -P, -K in the soil. The soil moisture storage change between rainy and dry seasons was 36.97 mm. The highest Total-N, -P, and -K of litter was 11.00 kg ha-1 y-1 at P3, 1.06 kg ha-1 y-1 at P2, and 4.35 kg ha-1 y-1 at P3, which was inconsistently associated with high soil nutrients. The highest Total-N was 0.40 (0-20 cm), 0.27 (20-40 cm), 0.30% (40-60 cm) at P4, Available-K was 1.69 (0-20 cm), 1.64 (20-40 cm), 1.87 cmol kg-1 (40-60 cm) at P5, and Available-P was 15.21 (0-20 cm), 14.06 (20-40 cm), 12.64 mg kg-1 (40-60 cm) at P1.

Abstract

Urea fertilization using controlled-release techniques is an effective way to reduce nitrogen (N) loss. One technique to decelerate N release and enhance fertilization efficiency involves applying Controlled Release Fertilizer (CRF) via Nano-Coated Urea (NCU) technology. The purpose of this study was to analyze the effect of coated urea application in reducing nitrate leaching rates and improving urea fertilization efficiency in loam soils. The materials used as urea coatings are Bentonite, which has been modified into nanosized particles. The study uses an incubation method with a lysimeter tube and destructive soil sampling to analyze soil nitrate and leached nitrate. The results showed that there was an increase in soil nitrate concentration in the LMC2 treatment (urea coating bentonite) by 28.05% and in the LMC3 treatment (urea coating nano bentonite) by 35.61%, compared to the LMC1 treatment (control urea) of 19.55%.
