Abstract

Biochar is a carbon-rich material that has various functions in improving soil properties. This research aimed to determine the characteristics of improvement in soil chemical properties and soybean plant growth by adding biochar from various biomass sources. The design used was a factorial complete randomized design with two factors. The first factor is the source of biochar biomass which consists of four treatments, and the second factor is the dose level of enrichment fertilizer which consists of four doses. Nutrients used for enrichment were N, P, and K, with the ratio between NPK being 8:5:4 based on the total amount of nutrients in soybean crops and their level of biochar. Soil material Ultisols used for planting medium was taken from Jasinga, Bogor District, West Java. The results show that adding enriched biochar with NPK (8:5:4) improves acidic soil properties, pH, C-organic, C/N, CEC, and NPK availability. Meanwhile, adding biochar (without NPK enriched) also significantly increased soil pH, C/N, and C-organic. Increased soil chemical properties and improvement of NPK availability were also followed by enhancement of dry weight of plants, correlated positively with N (r = 0.72**) uptake, P absorption (r = 0.32 ns), and K absorption (r = 0.98**), but negatively correlated with the weight and number of roots nodule (r = -–0.54*). A negative correlation between nutrient uptake, especially N, and the dry weight of the plant might have a particular effect on the falling activity of the root nodules, as indicated by the number and weight of the root nodules.
