“…The treatment combination of soil conditioner and biological agents can increase soil N content for 40.81 % and P available for 49.36 %. The research results of Sembiring et al, 2017b;Masdariah et al, 2019;Siswana et al, 2019 stated that the application of phosphate solubilizing microbes and organic matter can increase the P availability in andisol. Phosphate solubilizing microbes and organic matter are able to produce organic acids so that the availability of nutrient elements in the soil increases (Richardson, 2001;Gyaneshwar et al, 2002).…”

“…One effort that could be made to increase nutrient availability and andisol soil fertility is by applying soil conditioner enriched with biological agents, namely organisms that are useful in increasing the availability of nutrients for plants. According to Sembiring et al (2016;2017a;2017b), application of phosphate solvent microbes (Talaromyces pinophilus) can increase the availability of P by 9.63 to 49.78 % in andisol soil. Observations of Marbun et al (2015), shows that application of phosphate solvent fungi and organic matter can increase P uptake and potato plant growth on andisol soil affected by the eruption of Mount Sinabung.…”

Andisol soil contains a lot of heavy metals Al and Fe, which results in P being unavailable to plants and can cause low soil pH, this will inhibit plant growth. One effort that can be made to increase the availability of nutrients in the soil is by utilizing soil enhancing ingredients enriched with biological fertilizers. The research design used was factorial randomized block design (RBD) consisting of: Factor I: (biological fertilizers) M0 = without application, M1 = Talaromyces pinophilus (Hedgecock), M2 = Azotobacter sp, M3 = Mycorrhizae, M4 = Talaromyces pinophilus + mycorrhizae + Azotobacter sp. Factor II Soil enhancing ingredients, namely P0 = Without Soil Improvement, K1 = Zeolite 50 g, K2 = Humic acid 50 ml, K3 = compost / manure fertilizer for agriculture 50 g. From the results the combination of microbial treatment and soil conditioner can increase nitrogen in the soil by 2-40.81 %, cation exchange capacity by 1.7-44.29 % and P available by 1.3-49.36 %. Soil conditioner combined with biological fertilizers can improve soil quality in general, the best treatment is a combination treatment of T. pinophilus + mycorrhizae + Azotobacter sp. with coffee skin (M4P4).

Coffee plants need phosphorus nutrients for growth and fertilization in high quantities. Andisol has a very low availability of P. Efforts that can be made to increase the availability of P are by utilizing phosphate solvent microbes and coffee skin compost. The purpose of this study was to obtain the right type of microbial phosphate solvent and organic coffee skin ingredients in increasing the availability and growth of coffee plants in Andisol affected by the eruption of Mt. Sinabung. This study used a factorial randomized block design (RBD) consisting of 3 replications. Factor I: (Microbial Phosphate Solvents) M0 = Without application, M1 = Burkholderia cepacia, M2 = Talaromyces pinophilus, M3 = Burkholderia cepacia + Talaromyces pinophilus. Factor II Organic ingredients of coffee skin compost are K0 = without organic matter, K1 = 75 g, K2 = 150 g, K3 = 225 g. The results of the study showed that B.cepacia + T.Pinophilus + Mycorrhiza (M4) treatment can increase nutrient uptake of N, P and K of plants up to 12.3%, can increase plant uptake of P up to 18.84%, increase uptake of plant K up to 19.53%. The treatment of 225g of coffee husk compost (K3) can increase plant N nutrient uptake by 7.65%, plant P uptake to 26.11% and plant K uptake up to 14.12%. M4K3 application can increase N uptake up to 53.28%, P uptake up to 98.56% and increase K uptake of plants up to 56.45%. in general the best treatment is M4K3.

“…Volcanic ash contains heavy metals and harmful micro-substances which are easily deposited. The pH of Mount Sinabung volcanic ash ranged from 3.3 to 3.5, while the soil pH ranged from 4.4 to 6.5 which inhibited the activity of soil organisms (Balitbangtan 2014;Fatmala et al 2015;Sinaga et al 2015;Sembiring and Fauzi 2017;Sembiring et al 2017b) The eruption of Mount Sinabung reduced organic matter in the soil hence nitrogen content in the soil was low. This happens because exposure to the ash makes it difficult for soil organisms to survive, disrupting the decomposition process (Sinaga et al 2015).…”

“…This happens because exposure to the ash makes it difficult for soil organisms to survive, disrupting the decomposition process (Sinaga et al 2015). N-total in soil was affected by volcanic ash ranged from very low to low 0.04%-0.20% (Sembiring et al 2017a;Sembiring et al 2017b). Sembiring et al (2016) reported showed that total Corganic and N content in the soil affected by the eruption was 5.74% and 0.56%.…”

Abstract. Sembiribg M, Sabrina T. 2021. Diversity of non-symbiotic nitrogen-fixing bacteria and their potential in andisols affected by the eruption of Mount Sinabung, North Sumatra, Indonesia. Biodiversitas 22: 3539-3544. Nitrogen is the main macro-nutrient that is very important for plant growth. Nitrogen is absorbed by plants in the form of NO3-or NH4+ ions from the soil. The andisols affected by the eruption of Mount Sinabung alter the chemical, physical and biological characteristics of the soil. As a result, the population of beneficial microbes in the soil decreased, so soil fertility also decreased. The aim of this research is to determine the diversity of nitrogen-fixing microbes in andisol soil affected by the Mt. Sinabung eruption. The soil samples used in this research were collected from andisols affected by the eruption of Mount Sinabung. The isolation of non-symbiotic nitrogen-fixing bacteria was carried out using a nitrogen-free Jensen medium. The results showed that five non symbiotic N-fixing bacteria can increase the N content in andisols affected by Mount Sinabung eruption. Enterobacter cloacae can increase soil N by 111.76% as compared to without microbial application.
