Potassium humate, also known as humic acid fertilizer, is a soil amendment derived from naturally occurring humic substances. These substances are complex organic materials formed by the decomposition of plant and animal matter over millions of years.
 
Potassium humate is not a traditional fertilizer in the sense that it doesn't directly provide plants with essential nutrients like nitrogen, phosphorus, and potassium. Instead, it acts as a soil conditioner, improving the overall health and fertility of the soil in several ways:
Improves soil structure: Potassium humate helps to improve soil structure by binding soil particles together, which can help to improve drainage, aeration, and water retention.
Increases nutrient availability: Potassium humate can help to chelate nutrients, making them more readily available to plants. It can also help to hold onto nutrients in the soil, preventing them from leaching away.
Enhances microbial activity: Potassium humate can help to stimulate the growth of beneficial soil microbes, which play an important role in breaking down organic matter and making nutrients available to plants.
Promotes root growth: Potassium humate can help to promote root growth and development, which can help plants to better take up nutrients and water.
 
Overall, potassium humate can be a valuable tool for improving soil health and plant growth. However, it is important to note that it is not a substitute for traditional fertilizers. If your soil is deficient in essential nutrients, you will still need to apply a complete fertilizer to meet the needs of your plants.
