In recent years, many farmers find a weird phenomenon: when the soil is dry, it is red, a little wetter, a bit greenish, and the last is water. Soil green, red, what is the reason? Soil “face” the mystery First of all, certainly not a good thing. Perennial plant growth in this soil, often very few roots, premature aging is serious, root wilting, decay, and even death. After analysis, the reasons may be the following: Soil acidification In some places the initial soil is alkaline soil, long-term application of fertilizers makes the soil pH between 3 and 6, leading to soil acidification, soil iron, manganese, zinc dissolved pool of soil surface The soil is dry
