Community Service (PkM) is carried out by the Faculty of Agriculture, Universitas Methodist Indonesia by providing organic farming counseling and training on the manufacture of eco-enzymes from vegetable, fruit and local plant waste for the community, especially farmers. PkM was held on June 9, 2022 in Lumban Pea Timur Village, Balige District, Toba Regency, North Sumatera Province. The method used is to conduct organic farming counseling as well as training to make eco-enzymes by utilizing waste materials from vegetables, fruits and local plants. This is a solution to the problems and constraints faced by farmers in the form of decreasing soil quality due to the use of inorganic fertilizers. At the time of providing counseling, it was explained that there was a decrease in soil quality due to the application of inorganic fertilizers that had been carried out in the long term. Likewise, the explanation of efforts to fix and improve soil quality through the provision of eco-enzymes. The results of PkM with organic farming counseling are very effective considering that there are still many farming communities who do not understand that it is necessary to improve and maintain soil quality by using eco-enzymes. With the existence of organic farming counseling as well as the manufacture of eco-enzymes, the farming community becomes aware of efforts to improve the soil and what benefits can be obtained by making eco-enzymes. Thus, it is hoped that the Lumban Pea Timur farmer community will always be motivated to improve and maintain soil quality independently by utilizing vegetable, fruit and local plant waste materials.

Soil fertility is a determining factor for plant growth and production. For this reason, it is important to evaluate the status of soil fertility as a basis for soil management. This study aims to determine the status of soil fertility by analyzing the nutrient content found in the soil in Parbalohan Village, Simanindo District, Samosir Regency. Survey and soil analysis methods are used to evaluate soil fertility status. Soil sampling is carried out for each land map unit (SPL) that has been determined from the mapping results. Principal component analysis to identify soil fertility consists of five main components including cation exchange capacity (CEC), base saturation (KB), C-organic content, P-total and K-total based on the criteria of the Bogor Soil Research Center (PPT) 1995. Results research shows that the status of soil fertility in Parbalohan Village, Simanindo District, Samosir Regency is low soil fertility. Limiting factors include soil reactions, acid pH and low KB can be corrected by adding calcite or dolomite lime. Soils with limiting factors for C-organic content and CEC can be improved by adding soil organic matter, manure and compost.

The production of high quality seedlings is dependent on soil as planting media. Application of biochar derived from oil palm trunk onto oil palm seedling has been scarcely studied, especially on ultisol planting media. This research investigated the effect of oil palm trunk biochar on vegetative growth and nutrient uptake of belowground and aboveground tissues of oil palm (Elaeis guineensis Jacq) in ultisol pre-nursery planting media. Three types of oil palm trunk biochar derived from top, middle, and bottom section were used in this research. The application rates were 1, 2, 3 and, 4 % (w/w) during 12 weeks in a green house. This experiment used a non factorial randomized complete block design with three replications. The addition of biochars derived oil palm trunk (OPT) amendment significantly increased stem diameter, plant height, root biomass, shoot biomass. The highest respon rasio (RRs) for root and shoot biomass was 0.40, and 0.55, respectively, recorded at 2% application rates. The highest increase of N, P, and K uptake for belowground and aboveground tissues were resulted from B3 (3 % biochar top section), B2 (2 % biochar top section), and B2 (2 % biochar top section) treatments, respectively. Overall, the addition of biochar derived top section OPT at 2 % (w/w) could enhance stem diameter, RRs plant biomass, N, P, K uptake of belowground and aboveground tissues. The addition of biochar OPT at 2 % (w/w) should be recommendation in order to used as rate of biochar OPT for ultisols ammendment in oil palm pre-nursery

Soil fertility decline and sulfur deficiency are major constraints in shallot (Allium ascalonicum L.) cultivation, especially in sandy soils with low cation exchange capacity. Biochar and rice husk ash are potential soil amendments known to improve soil structure, nutrient availability, and crop productivity. This study aimed to determine the effect of rice husk biochar and rice husk ash on the growth, yield, and sulfur uptake of shallots. A factorial experiment was conducted using a Randomized Group Design (RGD) with two factors: biochar and rice husk ash, each at three dose levels. Results showed that biochar application improved the number of leaves, number of tillers, and bulb weight per unit, while rice husk ash had a limited effect, mainly enhancing leaf number at early growth. No significant interaction between the two amendments was observed across measured parameters, including sulfur uptake. These findings suggest that biochar contributes more effectively to shallot growth and yield than rice husk ash under the tested conditions. Further studies are recommended to optimize the combined use of organic amendments and to explore their long-term effects on soil nutrient dynamics and crop performance.
