Humic acid Content





Humic acid is a naturally occurring compound present in soil organic matter. It plays a vital role in soil fertility, plant growth and stress tolerance. After adding potassium humate to the soil, it helps to improve the soil structure and retain nutrients, making it easier for plants to absorb nutrients and water.

Adding potassium to humic acid can further improve soil fertility and promote plant growth. Potassium is an essential nutrient for plants, and by adding potassium humate to the soil, farmers and gardeners can ensure plants are getting this important nutrient.

Potassium humate has been shown to have several benefits when used as a fertilizer. It can help promote root growth, improve plant growth and yield, improve soil structure, increase nutrient uptake, and reduce stress to plants from drought, temperature fluctuations, and other environmental factors.

In addition to its benefits as a fertilizer, potassium humate is also organic, non-toxic and environmentally friendly. It's perfect for farmers and gardeners looking to improve soil health and plant growth without the use of synthetic chemicals.
