Introduction

Humic acid is a natural organic substance that is derived from the decomposition of plant and animal matter. It is commonly used in greenhouse production to improve water and nutrient management. In this article, we will explore how humic acid contributes to water and nutrient management in greenhouse production.

Water Retention

One of the key benefits of humic acid in greenhouse production is its ability to improve water retention in the growing medium. When humic acid is applied to the soil or growing medium, it acts as a sponge, absorbing and holding onto water. This helps to prevent water runoff and allows plants to access water for a longer period of time. As a result, plants have a more consistent water supply, reducing the risk of drought stress and improving overall plant health.

Nutrient Availability

Humic acid also plays a crucial role in nutrient management. It acts as a chelating agent, meaning it binds to nutrients and makes them more available to plants. This is particularly important in greenhouse production, where plants are often grown in soilless or hydroponic systems that rely on nutrient solutions. By improving nutrient availability, humic acid helps plants to absorb and utilize essential nutrients more efficiently, leading to healthier and more productive crops.
