Using humic acid in irrigation can help to improve soil structure, which in turn can help to reduce runoff and increase water retention. The acid helps to form a protective layer around the soil particles, reducing the amount of water that is lost due to evaporation. It also helps to improve the overall soil fertility, providing essential nutrients and increasing the availability of water and other essential elements.

Humic acid can also be used to help reduce the amount of fertilizer required for a given crop. It can help to break down complex molecules into more readily available forms, allowing plants to absorb the nutrients more efficiently. This can reduce the amount of fertilizer needed to reach the desired nutrient levels.

Finally, humic acid can be used to improve the overall microbial activity in the soil. Microbes help to break down organic matter and convert it into nutrients, which can then be used by plants. Increased microbial activity can help to improve soil fertility and also increase the availability of water, as microorganisms help to break down the soil particles and increase the amount of water that is absorbed.

By using humic acid in irrigation, growers can optimize the amount of water and nutrients available to their crops. This can help to reduce the need for heavy and costly fertilizers, while increasing the availability of water and the overall soil fertility. Humic acid can also help to reduce runoff and improve the overall microbial activity of the soil, helping to ensure that plants get the nutrients they need in an efficient and sustainable manner.
