PENGARUH BIOCHAR SEKAM PADI DAN KOMPOS TERHADAP C-ORGANIK, N-TOTAL, C/N TANAH, SERAPAN N, DAN PERTUMBUHAN TANAMAN JAGUNG DI ULTISOL

The maize crop is an important commodity other than rice in Indonesia. Maize production reached 30 million tons 2018. Efforts that can be made to increase on Ultisols Indonesia by the application of biochar husk and compost. Biochar has a high affinity for nutrients does not experience decay soil decades, while compost improve chemical properties increasing nutrient content. purpose this study was analyze effect combination properties, N uptake, growth Ultisol. This conducted with six treatments. results showed had C-organic N-total soil, but it did affect C/N incubated soil. Application 8 t ha-1 significantly improved plant height, dry weight, uptake plants.
