Look at the color of the soil. Acidic soils are mostly black, brown, and brown-black; mostly white, yellow-white soils are alkaline. Second, look at the growth of plants. The soil that grows well in rhododendron or coniferous plants is mostly acidic, while the well-growing soils such as horseradish, sea bass, and tamarisk are mostly alkaline. Four to see the soil pellets. There are many acid soil aggregates. Grab a handful of soil and watch carefully. Rice grains are usually acidic soils. Alkaline soils are white sand-like, with little or no granule structure.

Three to see the water situation. The soil is infiltrated immediately after watering. The water is more sloppy and mostly acidic. When watering, white foam appears, foaming, mostly alkaline soil. After the water is poured, the soil is soft and acidic; after watering, the soil is compacted and dried quickly, and there is a layer of white powder on the surface of the soil that is alkaline.
