Effectiveness Of Various Doses Of Silica Nanoparticles From Dayang Rindu Rice Husk On Phosphorus Availability In Ultisol Soil

Abstract

Silica nanoparticles are one of the research that continues to grow and become a concern in various fields ranging from health, animal husbandry, industry and agriculture. This study tested various doses of silica nanoparticles from dayang rindu rice husk to increase P availability in Ultisol soil. The research was arranged in nonfactorial complete randomized design (CRD) then the soil was incubated for 30 days by paying attention to soil moisture and then the soil was analyzed in the UNIB laboratory in a composite manner.  The doses used in the control study without naoparitkle silica treatment, 10 ppm, 20 ppm, 30 ppm, 40 ppm, 50 ppm, 60 ppm, 70 ppm and 80 ppm. The results showed that the dose of 10 ppm showed the optimum dose. The results of this study indicate that silica nanoparticles from dayang rindu rice husk have the potential as a solution to overcome inhibiting factors in the utilization of ultisol soil.
