How does white mortar become soil?Utilization and improvement of white clay soil

There are two ways to do this. One is to mix large soil with white ash to become soil. Because there is a lot of calcium carbonate and glue in the white ash paddle, it is not good in the soil, and only the silica and organic matter in the soil can be turned into soil.

The two methods are slow, put in the open air for a few years, let the rain, wind and sand leaves naturally join it, and the glue in the white mortar weathers and deteriorates, and it slowly turns into soil. Animal carcasses also turn to dirt under natural conditions.

White mortar cannot be turned into soil, and its damage to the soil is irreversible.

If you want to turn it into soil, you first need to get as much soil out of this location as possible, and then you can place new soil.

If the white mortar wants to be turned into soil, the soil and the white ash can be mixed and stirred, so that it can be slowly integrated.

Help her get the dirt done, and slowly turn into dirt and leave.

This white mortar can be mixed with some dry soil. Later, it can be turned into dirt.

The white clay soil distributed on the hill is mainly to prevent and control soil erosion;For the white clay soil distributed in the low-level areas, it is mainly necessary to pay attention to reasonable drainage and irrigation, or replant rice. The central link of white clay soil improvement is to supplement organic matter and mineral nutrients, deep ploughing to break the core soil layer or gradually increase the deep tillage layer, and improve the water and physical properties of the soil.

The main measures are:

The application of organic fertilizers, the practice of straw returning, and the planting of green manure, pasture and peat.

Increase the application of chemical fertilizers, mainly nitrogen and phosphorus mixed fertilizers. Due to the low total phosphorus content and lower available phosphorus content of white slurry, the application of phosphate fertilizer alone also has a significant effect.

Deep ploughing and soil modification. On the premise of not turning the white slurry layer too much to the surface layer, combined with the application of organic fertilizer, the deep tillage layer was gradually deepened to improve the poor water permeability of the bottom layer.

The lime powder used for sprinkling farmland is called quicklime, and the chemical composition is CAO.

Quicklime turns into mature lime when exposed to water and air, which is alkaline and is used to neutralize the pH of the soil, and some are also used to kill insects.

In the past, the white lime that brushed the wall was quicklime, and the conditions were limited in the past, so it was only necessary to paint the wall white. However, the painted wall is rough and easy to fall off, and it is not often used to paint the wall now. So the white ash mentioned by painting the wall now is not necessarily quicklime.

Quicklime will generate heat in the process of turning water into slaked lime, and Songhua eggs are cooked into food using this principle. Therefore, there is a simple way to identify, after dipping your fingers in water, there will be a feeling of heat after dipping your fingers in quicklime, of course, pay attention to safety during the experiment, and rinse in time to avoid corrosion.
