What is soil remediation
Soil remediation is the improvement and amendment of soil: it involves the addition of soil elements, organic matter, etc. on the ground. Soil amendments such as natural fertilizers (composted organic fertilizers), peat moss, or chemical fertilizers improve its ability to support plant life.
Chemical fertilizers also add nutrients to the soil to improve the soil, but the sole element of chemical fertilizers will make the soil environment worse. Soil amendments such as peat moss and organic fertilizers improve the soil environment by improving plant health through texture or drainage. But peat moss doesn't add nutrients to the soil. During the planting process, organic fertilizer compost can also improve soil texture as well as water supply and drainage by adding nutrients. The compost, peat moss and mulch can all help the soil retain moisture better. Soil amendments can also change soil pH. For example, peat moss is acidic and suitable for use around acid-loving plants.
How to remediate the soil
This is a type of soil remediation, but it is the most effective.
Amending soil with compost and other forms of organic matter can be considered a solution to soil problems and part of your regular landscape maintenance.
No matter what type of soil you have, adding soil amendments can improve your soil. It solves problems such as soil that is too sandy and does not retain enough moisture, or conversely, soil that is too clayey and retains too much moisture.
However, even if there are no known problems, you should amend the soil as part of your preventative gardening care program. Plantswell-fertilized plants are more likely to resist plant diseases and repel pest invasions. ?
Different measures should be taken for different degrees of floor damage. If the soil lacks fertility, apply green organic fertilizer to increase soil organic matter, restore and improve soil fertility. Many factors affect the soil, such as the impact of fertilizers present on the soil, etc. Let's talk about what to do if the soil is damaged and what causes these problems in the soil.
Count:
1: Decline in soil fertility: As farm manure has not been spread on agricultural land for a long time and straw is rarely returned to the field, the organic matter content of the soil will be reduced and the soil structure will be damaged and compacted. The situation is more serious. Actions taken: Increase the use of farm manure Farm manure contains more nutriments, which can supplement the missing nutrients in the soil and increase the organic matter content of the soil. In addition, you can also use the method of returning straw to the field, which has a better effect on increasing soil organic matter.
2: Soil salinization: unreasonable fertilization during agriculture, excessive application of chemical fertilizers and excessive use of nitrogen-rich fertilizers, resulting in low soil organic matter, lack of trace elements and soil compaction. The number of beneficial microorganisms in the soil decreases and cannot be replenished for a long time. What to do: Chemical methods can be used to resolve the problem. General chemical amelioration methods mainly use chemical substances such as gypsum, phosphogypsum and calcium sulfite to ameliorate the problem. The speed of amelioration of mmethods is relatively fast. The degree of soil salinization varies from place to place and measures should be taken according to local conditions.
3: Soil acidification: Excessive application of nitrogen fertilizers and physiological acid fertilizers will lead to an increase in acidic substances in the soil, making the soil acidified. Soil acidification will lead to the loss of soil nutrients, activation of harmful heavy metals in the soil, increase in harmful soil microorganisms, especially parasitic fungi, and accelerate soil depletion and emergence of soil-transmitted diseases. The impact of soil acidification therefore remains relatively significant. Steps to take: After harvesting agricultural produce, quicklime can be applied to the soil to adjust the soil pH. Additionally, we can also use precision fertilization. When we grow crops, we apply themWe apply fertilizers according to the needs of the plants, thereby reducing the amount of chemical fertilizers used.
