Main text core guide: Introduction to what kind of soil plain fill soil belongs to, its functions, and what can be planted in plain fill soil, with specific details as follows:
Plain fill soil is a type of three-category soil, containing very few impurities or none at all. It can be generally divided into several types such as碎石素填土 (crushed stone plain fill soil), sandy plain fill soil, and silty plain fill soil.
What type of soil does plain fill soil belong to?
Plain fill soil is a mixed type of soil, primarily composed of crushed stone soil, sand, silt, and clayey soil, formed by artificial placement and layered compaction, also known as compacted fill soil.
The function of plain fill soil
Plain fill soil is relatively loose. Only plain fill soil with clayey properties over 10 years old and sandy plain fill soil over 5 years old can achieve a certain density and can be used as the foundation for buildings.
The advantages of plain fill soil include improving bearing capacity and reducing compressibility, as well as treating potentially liquefiable foundations. The disadvantage is that its constituent materials are relatively disordered, and it has a certain degree of collapsibility, making it unsuitable for planting flowers and plants alone.
What is suitable to plant in plain fill soil?
Plain fill soil has no nutrients, but it is loose and breathable, and also has a moisture-retaining effect. Therefore, it is very suitable for cultivating potted landscape plants. It is recommended to place it in a semi-shady and semi-sunny corner and water it according to the "water when dry and stop when wet" method.
The above is the full content regarding the functions of plain fill soil, what type of soil it belongs to, and what can be planted in it. I hope it can help you and also hope that everyone will come to see more life experience and common sense!
