The whole process of soil improvement
Soil environment: too much sand and gravel, acid viscosity, easy consolidation, soil water permeability and air permeability is very poor, aggregate structure and cation exchange capacity are poor. Plant growth is weak, flower strength is weak, it is not easy to tiller branches. The weeds are serious.
Many kinds of plants have been planted in the original soil here, all of them grow poorly, and the soil is improved after solid analysis of soil properties.

After leveling, the horizontal trench is opened, and the depth method is referred to longitudinally.
Trench horizontally and turn the soil in accordance with the longitudinal requirements and methods.
Application of calcium and magnesium fertilizer can effectively improve soil acidity, 35 grams per square meter, or sprinkled with quicklime, 50 grams per square meter. Too much will damage the root system of vegetation, and too little is of little significance.
Rake flat, tidy up the perimeter. Smooth the slope that is conducive to drainage. The procedure for mechanical operation is the same when the area is large.
If conditions permit, soil disinfection can be carried out, either with methyl bromide or methanolone. It has a good killing and inhibitory effect on weed seeds, harmful bacteria, soil-borne diseases and nematodes in soil.
