Are there minerals in the soil What are the functions of soil minerals?

Yes It is located on the surface of the earth's land and has a certain fertility and is capable of growing plants. Soil is developed by rock weathering under various terrestrial conditions through the comprehensive action of natural factors such as biology and climate and the influence of human production activities. Soil is a complex and multiphase system of matter.

It is composed of mineral particles of different sizes, organic residues of various decomposition degrees, humus and living organisms, various nutrients, water and air, etc., and the volume ratio of each component is shown in the figure. The various constituent substances of soil influence, interact and restrict each other, and are in the process of complex physicochemical and biochemical transformation, and have complex physicochemical and biological characteristics. Soil has the ability to coordinate water, nutrients, part of the air and heat needed for plant growth and development, and this ability is known as soil fertility.

Soil is the base of terrestrial plants and the material basis for human agricultural production.

Soil has its unique material composition, basic properties and basic functions, has its own history of occurrence and development, is an independent historical natural body, and is one of the important components of the natural geographical environment. Soil is located at the junction of the lithosphere, hydrosphere, atmosphere and biosphere, and is the hub connecting the organic and inorganic worlds, and has become the constituent level of the biosphere. As a component of the geographical environment, soil is in the process of mutual influence and interaction with other physical geographical elements.

With the change of climatic, biological, topographic and other conditions and the passage of time, different soil types are formed accordingly. Therefore, the types of soil in nature are complex and diverse, and there are their geographical distribution laws in space and their evolution laws in time. Different soil types have different physicochemical properties, fertility conditions and utilization directions.

Soil is one of the basic means of production and the object of agricultural labor. The adoption of scientific farming systems and production measures by human beings will maintain and enhance the productive potential of the soil. Indiscriminate deforestation, grassland reclamation, and predatory land management will lead to the occurrence and development of soil degradation processes such as soil erosion, soil desertification, and soil salinization.

Therefore, it is of great significance to rationally develop and utilize soil resources and prevent soil degradation.

Yes Different things have different material compositions. However, there is a molecular composition in Ren and things, some of which are minerals and some are not, but minerals are the majority.

Absolutely, there are many kinds of minerals in the water, and there are not only water in the soil, but also mud, stones, and fertilizers.

Isn't soil made up of minerals?

Soil refers to a layer of loose material on the earth's surface, composed of various granular minerals, organic matter, water, air, microorganisms, etc., which can grow plants. Soil is composed of minerals weathered from rocks, organic matter produced by the decomposition of animal and plant and microbial residues, soil organisms (solid substances), water (liquid phase substances), air (gas phase substances), and oxidized humus.

Solid matter includes soil minerals, organic matter and nutrients obtained by microorganisms through light sterilization. Liquid matter mainly refers to soil moisture. Gases are the air present in the pores of the soil.

These three types of substances in the soil constitute a contradictory unity. They are interconnected, mutually restrictive, provide the necessary living conditions for crops, and are the material basis of soil fertility.

Soil is formed by the process of weathering, crushing, and transporting rocks over a long period of geological time. It can be said that soil is also made up of minerals.

Proof that the soil contains minerals, which can be verified by chemical testing. After the soil is dried, weigh it, add a certain amount of concentrated sulfuric acid in a closed seal, and the concentrated sulfuric acid will dehydrate the organic matter in the soil to form carbon dioxide, and the carbon dioxide will be introduced into the clear lime solution to precipitate, and the analysis can be reversed. After the soil is dried, weighed, filtered with distilled water, and weighed by residue drying, the weight will be reduced compared with that before adding distilled water, indicating that inorganic salts are dissolved in the water, resulting in weight reduction.

Soil minerals are formed by physical weathering and chemical weathering of rocks, accounting for more than 90% of the total weight of the solid part of the soil, and are an important supply of soil bones and plant nutrients. According to the genesis, it is divided into primary minerals and secondary minerals.

Soil minerals.

Primary minerals are detritus formed by the crushing of rocks through weathering, and their original chemical composition has not changed. There are mainly silicate minerals, oxide minerals, sulfide and phosphate minerals. Secondary minerals are new minerals formed by chemical weathering of primary minerals, and their chemical composition and crystal structure have changed, mainly including kaolinite, montmorillonite and illite particle size.

Soil minerals are formed by the long-term weathering of rock minerals on the earth's surface. Soil minerals generally account for about 95% of the weight of the solid part of the soil, forming soil particles of different coarseness.
