Results of previous research have proven that soil organic matter (humic and biochar compounds) can increase and maintain soil fertility and protect environmental resilience. The purpose of this study was to increase the abundance of microorganisms in young soil (regosol) with biopelet fertilizer composed of a combination of biochar, chicken manure, and shrimp waste to improve soil fertility. The experimental design used was a randomized block design with two factors, namely the composition and dosage of biopelets. The compositions of biopelet were 70% biochar, 15% chicken manure and 15% fish waste (B1); 50% biochar, 25% chicken manure and 25 % fish waste (B2): and 20% biochar, 40% chicken manure and 40% fish waste (B3). The dosage used was four levels (0, 2.5, 5, and 10 t/ha).The results showed that the application of biopelet fertilizer to the regosol soil reduced soil pH from slightly alkaline to near neutral, and the addition of up to 10 t biopelet/ha increased soil organic C content from 1.17% to 1.72%, as well as increasing the availability of N, P, and K nutrients. Improvement in pH, organic-C, and soil macronutrients was followed by an increase in the abundance of soil microorganisms, especially bacteria.

Mung bean is one of the leguminous plants that is very important to be developed and is a very popular crop for consumption in Indonesia. The use of inorganic fertilizer mix (NPK Phonska) is useful for increasing the production of this crop, but its continuous use without being balanced with soil improvement efforts can lead to negative effects on the soil and crop production. Thus, it is necessary to study the use of combination of inorganic fertilizers (NPK Phonska) with organic cow manure. This study aimed to determine the effects of doses of NPK Phonska fertilizer and cow dung manure on the growth and yield of mung beans. This study used a Randomized Block Design, with two factors. The first factor was dosage of NPK Phonska fertilizer mix, consisting of four levels i.e.: A0 (control, without provision), A1 (75 kg per ha), A2 (150 kg per ha), and A3 (225 kg per ha); and the second factor was composed of three levels, i.e.: K0 (control, without provision), K1 (15 ton per ha) and K2 (30 ton per ha). The experiment was done with three replications, so that there were 36 experimental units. The results showed that NPK Phonska fertilizer at a dose of 200 kg per ha (A3) and manure at a dose of 30 ton per ha (K2) gave the highest yield for all observation variables compared with other treatments, with a yield level of 1.82 tons per ha.
