Humic acid liquid is an organic blo- stimulant which enhances the growth of leaves, flowers, fruits and improves soll organic matter content and carbon content. Higher levels of soil organic carbon reduce bulk density, thus providing an improved rooting environment. In addition, soil organic matter holds soil water, which is an important attribute for plant growth in arid and mesic environments. Humic acid buffers soil pH to ideal level which helps the plant for better development and nutrients absorption. Thus acting as a natural chelator, they help plant roots to absorb nutrients more efficiently to create long term positive effect on soil quality and productivity.Humic acid helps in increasing soil nutrient contents, including the total soil nitrogen, total phosphorus, total potassium all in available form. It significantly increases the urease, sucrase, and phosphatase activities in the soil.
