Abstract: Ultisolss are one of the marginal soil types that dominate drylands in Indonesia. The main
problem of Ultisolss is poor nutrient conditions and low physical properties. The productivity of
this soil is low because it has low soil aggregate stability and also has poor biological and
physical properties. Research on superior cellulotic microbes in termite nests used as a starter for
the decomposition of agricultural waste and changes in the physical properties of Ultisols soil
needs to be carried out to determine the effect of applying the type and dose of compost resulting
from the degradation of cellulotic microbes to improve the physical properties of Ultisols soil.
This experiment was conducted from July 2019 to September 2021 at Ciparanje Experimental
Farm, Faculty of Agriculture, Univesitas Padjadjaran. The method used was experiment with
Randomized Block Design consisting of 9 treatments and repeated 3 times, namely straw
compost 5 tons/ha, 10 tons/ha, 15 tons/ha; sugarcane bagasse compost 5 tons/ha, 10 tons/ha, 15
tons/ha; oil palm empty fruit bunch compost 5 tons/ha, 10 tons/ha, 15 tons/ha. Based on the
research of compost degradation results by cellulotic microbes, rice straw compost 15 tons/ha
can provide the best aggregate stability results. |
