Clay minerals - 10 KG

They activate soil life, improve the exchange of nutrients between soil and plant and the soil dries out less quickly.
The use of clay minerals on sandy soil has a number of very positive properties: 

These clay minerals:
Improve the soil structure and the air and water circulation of the soil
Make the sandy soil easier to work
Ensure that the soil does not dry out so quickly and therefore you do not need to spray as much
Contain a naturally rich micro life. As a result, clay minerals activate soil life and improve the exchange of nutrients between soil and plants
Hold nutrients better because clay has a buffering capacity
Are rich in minerals, of which there is often a shortage on sandy soils
Are very suitable for the vegetable garden

Use in construction, renovation and maintenance on (drought-prone) sandy soils
