In the usual planting management, many details can reflect the current state of the soil, helping us to judge whether it has started to deteriorate.
First, blue, red, and white frosts appear on the ground. Green, red and white are the most intuitive reflections of the color of the ground. The appearance of these three conditions indicates that there is a large accumulation of mineral elements in the soil. "Red" is the appearance of "Porphyra sp." on the ground, which is an indicator plant of saline-alkali. Its appearance indicates that the salt content in the soil is already very high, reaching about 5/1000, and the red light is on. "White" is the accumulation of a layer of salt on the surface of the ground, the people called back "white alkali." "Green" is a long green moss, green moss has two favorite, one is wet, and then saline. The above three phenomena indicate that soil salinization is already serious and the soil needs to be improved. The emergence of blue and white hoarfrost directly reflects the serious surplus of chemical fertilizers we put into the soil, or the reduction of soil organic matter deteriorates the soil properties and reduces the fertility conservation.
Second, the amount of earthworms in the soil is reduced.蚯蚓 likes organic-rich soil. If the soil is deteriorating, it tends to harden, the organic matter content decreases, and the soil lacks the necessary food. The survival and reproduction capacity of earthworms will be greatly reduced, and the ability to improve soil remediation will be weakened.
Once again, the phenomenon of roots, dead trees and lack of elements increased. Organic matter in the soil is reduced, salinity is increased, permeability is reduced, the mobility of the elements in the soil is reduced, the activity of the roots is reduced, and vegetables are more prone to rooting, root diseases are more easily infested, nutrient elements are more difficult to absorb, and a vicious circle is formed .
In addition, plants such as mosses prefer a damp environment, especially if nitrogen is used excessively, which is a sign of soil deterioration.
