The application of DCT products to soil represents an innovative approach to mitigating the adverse effects of high sodium levels in salt-affected soils.

The organic compounds in DCT products, which are integral components of soil organic matter, offer a multifaceted solution to soil salinity problems by improving soil structure, enhancing nutrient availability, and facilitating the leaching of excess sodium ions.

DCT products achieve sodium reduction through several mechanisms.

First, they improve the physical structure of the soil.

By increasing the aggregation of soil particles, these substances enhance soil porosity and aeration, which in turn facilitates the percolation which is the movement of water through the soil profile.

This improved water movement helps to leach excess sodium ions from the root zone to deeper layers, reducing the concentration of sodium in the soil where most plant roots reside.

DCT products work to enhance the cation exchange capacity (CEC) of the soil. The CEC is a measure of how well soil can retain and exchange cations (positively charged ions) between its particles.

By boosting the soil's CEC, DCT products enable the soil to hold onto beneficial nutrients such as calcium, magnesium, and potassium more effectively, while simultaneously displacing sodium ions, which are then washed away by irrigation or rainwater. This exchange not only reduces the sodium content but also improves the nutrient balance in the soil, promoting healthier plant growth.

The organic compounds in DCT products are designed to stimulate microbial activity in the soil, which plays a crucial role in soil health and nutrient cycling. The enhanced microbial activity can lead to the formation of soil aggregates, further improving soil structure and its ability to leach harmful salts.

In summary

the application of DCT products to salt-affected soils offers a promising strategy for reducing sodium levels. Through mechanisms such as improving soil structure, enhancing cation exchange capacity, and stimulating beneficial microbial activity, these organic compounds facilitate the removal of excess sodium ions, improving soil salinity, and enhancing plant growth.
