The objectives of the research were: to determine some of the chemical properties of bokashi (swiftletpoop, banana peels, and tea dregs) and to determine the effect of giving different types of bokashi and their incubation time on some of the chemical properties of Ultisols soil.

This research was conducted from February – to March 2021 in the Jl. Talang Sari. Samarinda. East Kalimantan and analysis of bokashi fertilizer and soil was carried out at the Soil Laboratory, Faculty of Agriculture, Mulawarman University, Samarinda.

The research treatments consisted of: without giving bokashi (p0), giving swiftletpoop bokashi (p1), giving banana peel bokashi (p2), and giving tea dregs bokashi (p3) where each bokashi type treatment was incubated for 2 weeks and 4 weeks. .

The research activities included: (1) making swiftletpoop bokashi, banana peel bokashi, and tea dregs bokashi, (2) Ultisol soil media preparation and treatment of bokashi types (swiftletpoop bokashi, banana peel waste, and tea dregs waste) and incubation for 2 and 4 weeks, (3) analysis of some chemical properties of bokashi fertilizer, and (4) analysis of soil after incubation for each type of bokashi fertilizer treatment.

The results showed that: (1) bokashi fertilizer incubated for 4 weeks in Ultisols soil resulted in higher soil pH, C-organic content, N-total, available P and available K and higher C/N ratio compared to the incubation period. for 2 weeks; (2) Application of bokashi fertilizer on Ultisols soil increased soil pH, C-organic content, N-total, available P and available K and C/N ratio of Ultisols soil compared to no bokashi fertilizer; and (3) Application of bokashi fertilizer with swiftletpoop resulted in the highest total organic C and N, application of banana peel bokashi fertilizer resulted in the highest soil pH and available P, while tea dregs bokashi application resulted in the highest C/N ratio.
