Soil remediation means soil improvement and soil correction: it means adding soil elements, organic matter and so on to the soil. Such as natural fertilizer (organic manure compost), peat soil or chemical fertilizer. These soil amendments improve its ability to support plant growth.
Chemical fertilizer can also increase soil nutrients and improve soil, but the single chemical fertilizer element will worsen the soil environment. Soil improvers such as sphagnum and organic fertilizer can better improve plant health through their texture or water supply and drainage, thus improving the soil environment. But peat soil will not increase the nutrition in the soil. In the process of planting, organic manure compost can also improve soil texture and water supply and drainage by adding nutrients. Compost, peat moss and plastic film mulching can all help the soil to keep water better. Soil improvers can also change the pH value of soil. For example, sphagnum is acidic and suitable for use around acidic plants.
How to repair soil
This is a kind of soil remediation, but it is the most effective.
Improving soil with compost and other forms of organic matter can be regarded as part of solving soil problems and daily landscape maintenance.
No matter what kind of soil you have, adding soil improvers can improve your soil. It can solve the problem that, for example, too much sandy soil can't keep enough water, or on the contrary, too much cohesive soil can keep too much water.
However, even if there are no known problems, you should correct the soil as part of the horticultural preventive health care plan. Fertilized plants are more resistant to pests and diseases. ?
