Analysis of Phosphorus on Prill and Liquid Fertilizer

Abstract

The research was conducted on the determination of the levels of phosphorus on prill and liquid fertilizers using the UV-Visible method compared with Indonesian National Standard (SNI 02-2801-2010). Phosphorus is the most important nutrient for crop to gain the high productivity. The sample of the research were prill and liquid fertilizer that had SNI. Phosphorus levels in NPK fertilizer were analyzed using the UV-Vis spectrophotometer method. The result was an analysis of phosphorus levels in prill fertilizers of 14,67% and phosphorus levels in liquid fertilizers of 18,55%. These results are in accordance with the Indonesian National Standard (SNI) 2803:2010, which is a minimum phosphorus content of 8%.

“…Increasing agricultural production to meet the community's food needs is necessary. The most dominant elements found in inorganic fertilizers are elements of N, P, and K (Oldham, 2017;Rahmawati & Widyasari, 2022). Compound fertilizer from (N, P, K) is one of the inorganic fertilizers that can be used efficiently in increasing the availability of macronutrients (N, P, and K), replacing single fertilizers such as SP-36, ZA, and KCL, which are difficult to obtain in the market and very expensive.…”
