Question

what is a common agricultural use of a mineral

Answer 1

Organic agriculture is a production management product, without chemical agents and to protect the health of the environment, the use of farm inputs and to naturally strengthen and develop the health of ecosystems and soils.

However, organic farming organic inputs instead of simply replacing chemical agents, because improper use of conventional and non-organic materials also disrupt the biological cycle system.
In general, biological or organic agriculture on farm viability of the system in general rests with reinforced soil and soil microorganisms might also be useful.

Soil is an important component of the agricultural fields as infrastructure is important for plant growth and soil chemical and physical changes caused by human intervention disrupt the soil and the water system, and regardless of negative and dangerous consequences just trying to earn money and meet the food needs of the community.

In organic farming the soil is very important. The use of bio-fertilizers, minimum tillage, crop rotation, strengthen and improve the soil and fermentation of organic material useful animals and increase soil nutrients, improves soil texture and use of compost and organic fertilizers and animal makes the soil more fertile and thus soil erosion significantly reduced.
Apart from the minerals, soil containing organic matter and humus arise as a result of biomass decomposition. In most agricultural soils in warm areas to be included in this article only a small percentage of 1% total solids and total up the soil, which is very important for soil fertility.

Answer 2

Organisms and micro-organisms

One teaspoon of soil contains millions of active organism that some animal origin and others are derived from plants. Organisms are very different in size. Some of them are visible to the naked eye, such as earthworms, tail spring, the lead animal. Most of them are very small and can be seen only with a microscope, so called micro-organisms.
The microorganisms, bacteria, and protozoa are. Key elements of the quality and fertility of soil microorganisms are invisible, but for us humans to do the work. They are so many and the number increases, the more the natural fertility of the soil.
For example, some large soil organisms including earthworms, spiders, snails, scraper, beetle, spring tails, mites and millipedes.
Some soil microorganisms include bacteria, algae, fungi, protozoa and actinomycetes.
Most farmers all pest organisms in terms of their look and think how they can destroy them. While only a small number of microorganisms can cause damage to the product. And the main and most important function of most of the soil, fertilize the soil.

Answer 3

The effects of soil microorganisms:
microorganisms
1. to help decompose organic matter and produce humus (article useful biochemical composition of organic and inorganic substances) are.
2. The result of mixing organic matter with soil particles and this causes soil particles are stable.
3. By creating tunnels in the soil, encouraging plants take root and soil are also better ventilation and causes the release of nutrients from mineral particles are.
4. control of pests and disease organisms that affect the roots of the plants, are.
5. Most organisms are very sensitive to soil moisture and soil temperature. Since the plant roots and soil organisms from the air used to good air flow in the soil is very important for development and growth. The activity of soil organisms when the soil is too dry, too wet or too hot to be reduced. The most important role in the balance of microorganisms in soil and foods are hot and humid weather.


Soil structure
In addition to mineral and organic soil, some pores (pores) in the soil, water or air that is filled. The method of making particles and pore space as "soil structure" called. Small pores and large pores are suitable for water conservation and rain water is allowed to drain and ventilation can help.
In soils with good structure, mineral particles and organic materials soft parts are stable. Organic matter act like a glue, causing the soil clinging to each other as different parts of the process by soil organisms (organisms and micro-organisms) such as earthworms, bacteria and fungi can be supported. However, this condition can be wrong with management of soil, such as soil tillage farm in wet conditions, causing soil compaction.

 
Survey and soil testing

Simple observation test is a simple method of soil with a shovel because soil fertility due to soil structure and evaluate. By Bill garden beds, a form of clay is easily separated as far as possible avoid soil compaction or deformation. For this purpose, the shovel into the soil vertically and hole the size of the Bill do. Bill as much as 15 cm in the pits Dip. Now you can see the different layers. Distribution of humus, the number of pores (porosity) or degree of soil compaction, density and root depth, signs of earthworms and other soil organisms and the presence of soft soil in that review.

Laboratory Method: Most people have a lot of faith in science. So when we come to soil fertility, farmers may want your soil analyzed in the laboratory. Although soil tests may give specific information about some of the questions we have, but farmers should not expect much from these experiments.
For example, most of the problems to analyze the characteristics of the food is concerned, while always a general view of essential nutrients to plants is evident. For example, it may be high enough mineral nutrient uptake by the plant roots are not able to use it. Also, some of the experiments by dissolving the samples, they are threatened. In other words, reduce the food available to plants which can be a real stimulus to agriculture considered common.

Check other foods, such as nitrogen, strongly depends on the time of sampling. In some cases, the chemical analysis of soil, such as soil pH and determine the shortages of food (such as zinc and potassium) is useful.

why_organic
Agricultural producer of organic products, particularly to obtain information about the contents of the soil and measure it. The chemical analysis of soil for residual effects of pesticides are too complicated and most important part of it is that we must search for pesticides which of course would be very costly procedure. Physics experiments closely related to potential water retention and soil texture and accurate sample should be collected.
One example of an active biological degradation of soil organisms should be performed with special laboratory equipment which is extremely costly. Although the use of soil analysis laboratories in the field according to scientific methods are appropriate and cost because it is limited. If the soil test to make sure that significant aspects of the study or not and that results should be seriously discussed.
