What are the main components of soil? Free of chemical fertilizers and other pollution!

It should be silicate and silica, the ratio is not very clear.

It is composed of various granular minerals, organic matter, water, air, microorganisms, etc., and 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.

The amount of organic matter is an important indicator of soil fertility, and it is closely combined with minerals. In the general cultivated layer, the organic matter content only accounts for the dry weight of the soil, and the cultivated layer is less, but its role is great, and the masses often call the soil containing more organic matter "oil soil".

Composition of nutrient soil: It is prepared by mixing fertile field soil with rotting manure.

Due to frequent fertilization and tillage, the fertility is high and the aggregate structure is good, which is one of the main raw materials for the preparation of nutrient soil. The disadvantage is that the surface layer is easy to harden when dry, and the ventilation and water permeability are poor when wet, so it cannot be used alone. Top-sandy loam soils that have been planted with vegetables or legumes are best.

It is a culture soil made by mixing leaves and weeds of various plants into the garden soil, adding water and human feces, and accumulating, fermenting and rotting. The pH is acidic. It needs to be sieved after exposure to the sun.

Humus of nutrient soils:

In the production of substrate nutrient soil, humus fermentation is a key step. In the past, the old-fashioned humus clay was made by using primitive methods, and the raw materials were piled up and fermented for up to one or two years. The operation cycle is long, the maintenance cost is high, and the labor intensity is also large, which is no longer suitable for the rapid commercial operation needs.

The use of Fuld microbial starter culture to make humus completely solves the above problems. Fuld microbial starter uses Japanese biotechnology, which contains a large number of functional microbial flora, which can quickly decompose and ferment organic materials. The humus soil is made with Fuld biological starter culture, which ferments rapidly, and can be fermented in about 20 days.

The above content reference:

1. Peat: Peat is the main component of potted nutrient soil, accounting for more than half. Peat is a non-renewable natural resource that is a non-renewable natural resource that is rich in organic matter and humic acid, light material, good water retention and air permeability, not only for cultivation soil, but also as a soil conditioning and improvement substrate.

2. Cocon: Coir is a crushed coconut shell, rich in crude fiber, due to its degradable characteristics, it is also an environmentally friendly planting substrate, water retention and air permeability, and it is cheap. At the same time, it belongs to the agricultural and sideline products of coconut processing, which solves the problem of coconut shell processing, and is used to process into coconut peat and turn waste into treasure, which is an environmentally friendly solution.

Due to its single nutrient content, its main role is to increase soil permeability and water retention, and it is generally not used alone. 3. Perlite: Perlite is an acidic lava with a porous structure, rich in trace elements such as silicon and iron, with light material, good air permeability and drainage, mainly used for drainage, aeration, and soil improvement, and can also be used with peat and vermiculite as a substrate for cuttings, which is conducive to hair roots.

However, due to its clear self-weight and easy to float after watering, the addition amount should not be too much. 4. Slow-release fertilizer: Slow-release fertilizer is mostly compound fertilizer particles, rich in nitrogen, phosphorus, potassium and other nutrients required for plant growth, the fertilizer effect is mild, easy to dissolve, volatile, sustainable release, and the fertilizer effect can be maintained for 2-3 months.

The yellow and gray particles in the nutrient soil are generally slow-release fertilizer, which is easy to use, and can be used as soil mixing or base fertilizer. In addition, the composition of nutrient soil with different functions will be slightly different, but it is still generally based on peat, coconut peat, perlite, slow-release fertilizer, and other particles such as river sand, vermiculite, maifan stone, deer bath soil, red jade soil, etc. Families raise flowers, you can collect humus, garden soil, deciduous soil, etc., after drying, sifting, to remove impurities, and then add some organic fertilizer appropriately, the effect of planting flowers is also very good.

Nutrient soil is specially formulated to meet the growth and development of seedlings, containing a variety of mineral nutrients, is loose and aerating, strong water and fertilizer retention ability, no pests and diseases of the bed soil. Nutrient soil is generally prepared by mixing fertile field soil with rotting manure.

Features: First, nutrition, with a good soil ecological environment, can meet the healthy growth of crops.

Second, it has strong water and fertilizer retention ability, which can improve the survival rate of plants.

Third, simplify operation and facilitate management.

Applicable plants: flower plants, foliage plants, fruit and vegetable crops, succulents, wood and shrubs lawns.

Soil contains minerals, organic matter, living organisms, water, and air, soil refers to a layer of loose material on the earth's surface, liquid matter mainly refers to soil moisture, and gas is the air present in the pores of the soil.

Soil minerals are mineral particles of different sizes (sand, soil and gum) formed by the weathering of rocks. There are many types of soil minerals, and the chemical composition is complex, which directly affects the physical and chemical properties of the soil, and is one of the important nutrients of crops.

The solid phase of soil is mainly composed of a variety of mineral particles of different sizes and shapes, and for some soils, in addition to mineral particles, it also contains organic matter.

Soil is a natural body composed of several layers of soil of different thicknesses, and the main component is minerals. The differences between soil and parent material are mainly manifested in morphological characteristics or physical, chemical, mineral and other properties. For engineering purposes, soils are considered to be regolith or loose rock material.

This explanation is strictly incorrect: soil is formed by weathering of the parent material (rocks), which has different properties from the parent material.

Soil is composed of a mixture of minerals and organic matter produced by various weathering and biological activities, and exists in solid, gaseous and liquid states. Loose soil particles combine to form a soil filled with gaps, and in these pores there are dissolved solutions (liquids) and air (gases). Therefore, soils are generally considered to have three states.

The density of most of the soil is 1 2 g cm. Most of the earth's soils were formed later than the Pleistocene, and only a few soil components were formed earlier than the Tertiary period.

Hello, the question you asked has been seen, I will sort out the information first, and I will reply to you immediately.

Almost half of it is glassy silica, which is caused by meteors hitting the moon. For billions of years, the rapid destruction of the moon's surface soil melted into glass, and then smashed into tiny fragments. Lunar soil is rich in nuclides and noble gases such as 3HE, helium, neon, argon-38, and other nuclides and noble gases.

The lunar soil is rich in silicon, aluminum, potassium, barium, lithium, rubidium, zirconium, hafnium and rare earth elements, and the moon is also rich in titanium. Lunar soil also contains a certain amount of meteorite components.

Hope mine is helpful to you.

The composition of the soil includes:Minerals, organic matter, moisture and air.

Soil, or soil, is a loose surface layer on the earth's land surface that has a certain fertility and can grow plants. It is the weathering of rocks formed and developed under the combined action of biological, climatic, topographic and other factors. The composition of soil includes four substances: minerals, organic matter, water, and air.

Soil-relatedThe main characteristic of the soil is its ability to continuously supply and regulate the water, nutrients, air and heat required by plants for life, i.e., soil fertility. Fertile soil can make water, fertilizer, air and heat conditions reach a stable, even, sufficient and suitable degree, and can resist the influence of harsh natural conditions to a certain extent, and adapt to the needs of plant growth.

Since the beginning of agriculture, soil has been the basic means of production for agricultural production. One.

There are some metals that are found in the soil in the form of chemical compounds.

Such as aluminum, iron, etc.

Main** Humus contains a large number of elements such as nitrogen, phosphorus, potassium, thin, calcium, etc., as well as trace elements, which can be released by microbial decomposition for crop absorption and utilization.

It generally includes particle size components, mineral components, and liquid phase components.

The structure of soil is the form of existence of soil, and it is the interrelationship of mineral particles in soil. In addition to the size, shape, surface characteristics and particle size gradation characteristics of soil particles, the structural characteristics of soil also include the arrangement and collection relationship between particles, the size of pores, and the characteristics of inter-particle connection.

The difference between soil and parent layer is manifested in morphology, physical properties, chemical properties and mineralogical properties. Due to the interaction of the earth's crust, water vapour, atmosphere and biosphere, the soil layer is different from the parent layer. It is a mixture of minerals and organic matter, in solid, gaseous and liquid states.

The loose soil particles combine to form a soil full of gaps. These pores contain dissolved solutions (liquids) and air (gases). As a result, soils are often considered to have a species.

The density of most of the soil is 1 2 g cm. Soil is also known as "Earth" in English – the name of the planet we live in, and its essence. Only a few soil components on Earth were formed earlier than the Tertiary period, and most will not be earlier than the Pleistocene.
