ABSTRACT

This study aims to solve the problem of sustainable agriculture by combining the main plant nutrient - nitrogen (N) with Humic/Fulvic acid compounds which are synthesized from fermentation by-products from food processing plants and waste from livestock and poultry production The current product is produced by mixing method under normal conditions, the Humate/Fulvate bonds are not enough to form chemical bonds to bring about agronomic efficiency for plants and the ability to improve the soil Considering the existing Urea melt source at Ca Mau Fertilizer Plant, it can be used in combination with fermented Fulvic acid source to produce a pellet fertilizer product with more outstanding properties due to Urea-Fulvic linkage and other intermediate and trace elements

Fertilizer is a product that is applied seasonally and, in all regions, where there is agricultural cultivation Therefore, the problem of transporting and storing products is very necessary at intermediate warehouses before being applied simultaneously on the crops Ensuring the quality of the product is preserved during the waiting time for the crop but still retains the same chemical and physical properties as when it was first produced, which costs a lot of fertilizer manufacturers Many studies have shown that the addition of intermediate and trace elements in fertilizer, in addition to helping plants have enough nutrients, also helps to make fertilizer products more stable in terms of physical properties, easier to dry, and caking in storage

Fertilizer products that have intermediate and trace elements can help plants absorb nutrients in adverse conditions such as alkaline soil, saline soil

This research data will serve as the basis for the design of a highly efficient fertilizer production line from the available conditions of the plant, contributing to the Company's product diversification strategy and the fertilizer industry in general
