Biological planting media as marginal land resolution with local bio introduction

Abstract

Soil is a planting material that has various functions in it, its main function has a lot of influence on life and almost all living things on earth. The most significant role is when the soil becomes a cultivation medium for plants, it is required to provide all the needs of plants to live so the role of soil is very crucial. Control of land improvement still needs to be improved through increasing the natural biology of the local location or adding soil amendment microorganisms to build existing ecosystems to improve the quality of the land. The research method uses the Completely Randomized Design (CRD) method where each treatment indicates several compositions of planting media. The treatments are divided into 3, namely treatment A consisting of 20% Coco Fiber, 20% Husk Charcoal, 20% Goat Manure, 20% Agricultural Lime, and 20% Microorganism Colony. Then followed by treatment B which is 20% Coco Fiber, 10% Husk Charcoal, 20% Goat Manure, 20% Agricultural Lime, 30% Microorganism Colony, and finally treatment C which is 20% Coco Fiber, 20% Husk Charcoal, 10% Goat Manure, 10% Agricultural Lime, 40% Microorganisms Colony. Treatment B shows to be the most successful treatment where the results of agronomic observations, nutrient availability, and the availability of microorganisms and their decomposition process provides the most significant results and has a positive impact of approximately 4.6% on agronomic observations, 5.1% on observations of the role of microorganisms, 6.3% on observations of media nutrients, and 4.2% on observations of organic content and pH. Stabilizing the provision of microorganisms with the types of Nitrogen Fixers, Phosphate Solubilizers, Decomposers, and Root Infectors can make the sustainability of decomposition and decomposition rates run well and a comprehensive symbiotic mutualism occurs so that the introduction can be done with this biological planting media.
