Clay soils with poor structure are a problem both for farmers and the environment, as water is not able to penetrate the soil. Instead, the water runs off carrying away vital nutrients, leading to eutrophication of lakes and sea. Improving soil structure with lime allows water to penetrate into the soil and plants to absorb substances such as phosphorus. This provides a long-term effect of up to 15 years and quick financial returns. The effects are environmentally and financially beneficial, as the money you invest in fertilisers has a benefit instead of literally being flushed away.
