To understand its importance, it’s important to understand its role in soil development. In practical terms, soil colloids are clay and organuc matter. Approximately 90% of the soils sampled throughout Irelandare sub-optimal in either Phosphorus, Potassium or soil pH. Besides this, cultivation of crops without manuring decreases the fertility of soil.
