Abstract

Rice is a staple food in Indonesia and its production is crucial to meet the increasing demand. However, industrial pollution poses a threat to rice cultivation, particularly in the Rancaekek paddy fields. This study aimed to investigate the effect of NPK Bio-Organomineral fertilizer on the growth and yield of rice plants in industrially polluted land. The experiment was in September 2023-February 2024 and conducted in a greenhouse using Inpari 32 rice varieties. The research was set up in a randomized block design with eight treatments and four replications. The treatments consisted of: control (no fertilization), NPK 250 kg/ha, and NPK Bio-Organomineral treatment with doses of 125; 250; 375; 500; 625; 750 kg/ha. The results showed that the application of NPK Bio-Organomineral fertilizer increased the number of productive tillers, vegetative tillers, and grain dry weight. The optimal dose of NPK Bio-Organomineral fertilizer at a dose of 750 kg/ha showed the best results in increasing the number of vegetative tillers and productive tillers, while the dose of 375 kg/ha showed the best results economically in increasing the grain dry weight. This study shows that Bio-Organomineral NPK fertilizer can be an effective solution to improve soil fertility and increase rice yields on industrial waste polluted land.

Abstract

This research discusses the critical role of phosphatase enzymes in soil, particularly in the phosphorus cycle and soil fertility. Acid and alkaline phosphatases are identified as crucial components, with their activities serving as indicators of soil fertility. This study evaluates the soil chemical and biological characteristics in mangosteen orchards in the Mangosteen Thematic Village, specifically in monoculture and polyculture cultivation patterns on slopes ranging from 8-15%. Soil pH, organic C, available P, total P, soil respiration, microbial C-biomass, and phosphatase enzyme activities were assessed at 0-20 cm and 20-40 cm depths. Total P did not show significant changes based on cultivation patterns. The results show that the soil pH values tend to be acidic to slightly acidic (5.21- 5.45) with no significant differences based on depth. Organic C, available P, soil respiration, microbial C-biomass, and acid phosphatase enzyme activity were higher in polyculture cultivation patterns but alkaline phosphatase enzyme activity was higher in monoculture. The cultivation pattern influences the dynamics of agricultural ecosystems and should be considered in land management to enhance productivity and soil ecosystem balance.
