The Organic Compost: Why You Should Be Using?
The first thing to do before embarking on the great adventure of organic composting is to know his own motivations for this activity. Each one has his reasons and these can vary from one individual to another. It is therefore important to evaluate their needs in order to be able to answer them and thus, find satisfaction personal to organic compost. But first, what is compost? The compost comes from the putrescible residues decomposed by the action of microorganisms, insects, and earthworms in the presence of oxygen, which has reached a state of equilibrium. Dark brown in color, ripe compost has the appearance and the smell of a potting soil.
And the composting activity?
It is a method of biochemical treatment that involves using the action of various aerobic organisms (under conditions where oxygen is present) to decomposes under control (aeration, temperature, humidity), and so accelerated, putrescible matters. That, with a view to obtaining an amendment organic. Stable from a biological point of view, hygienic and rich in humus, the obtained material is called compost.
Here are some of the motivations that can be evoked to transform organic matter at home:
– Have a vegetable garden, plants, and flowers that are robust and healthy;
– Return to the earth what she has given us;
– Feed the soil that will feed the plants;
– Decrease by 40% the volume of waste and thus reduce pollution;
– Substitute compost for chemical fertilizers;
– Soil composting eliminates many pathogens and diseases contained in the soil;
– Save significant amounts of costs for collection, transportation, and landfill management;
– Reduce air pollution since the decomposition of organic matter into anaerobic (in landfills) releases biogas, including methane, which is one of the main greenhouse gases;
– Use it as a gardening and outdoor activity, etc. ;
– Make ecological gardening;
– Avoid wasting resources.
But above all, there are two main reasons for composting that are order scientist. These same reasons constitute principles for which the Domestic composting is gaining momentum. It is about improving the soil quality and reduce pollution.
To improve the soil:
A handful of soil contains mostly mineral substances that are inert, dead. The soil is composed of tiny particles of rock, air, moisture, and a plot of organic matter called humus. Humus provides essential elements for soil fertility: nitrogen, phosphorus, potassium, and calcium. It stimulates the natural regeneration of the soil, which helps improve plant growth. These are healthier since they better assimilate the minerals contained in the soil and make more easily their vitamins. The more humus there is in a soil, the more it is rich in nutrients and the better it retains the moisture and air necessary for the growth of plants. Moreover, compost can serve as a barrier to unwanted. Acids organic compounds it contains, also called fatty acids, promote the control of pests and stabilize pathogens. In addition, humus can help prevent diseases in plants by reducing deficiencies that cause them to be attacked.
Compost promotes aeration and drainage of the soil and reduces the texture. This phenomenon is due to a substance called humic acid contained in the compost finished. This substance makes it possible to lighten the clay soils and therefore, to improve their drainage. Mixed with straw, compost helps control bad herbs and protects the plant roots against the sun and the wind. Compost is a good long-term fertilizer, contributing mainly to as an organic amendment and thus improves soil health. Compost acts in the short term to quickly fill important needs plants, so it is a good substitute for synthetic fertilizers. At the end of the account, it is the health of the population that will benefit from the amended soil of a good compost, because vegetables from the kitchen garden will contain more vitamins, minerals, and fiber essential for good health.
To reduce pollution:
The USA People are among the largest producers of waste in the world. The organic materials alone account for more than 40% of the volume of the bag approximately 675 kilograms (about 1,500 pounds) per family of four people, every year. These organic materials come from residues of kitchen and garden. The use and treatment of these materials determine whether they will remain a resource or they will become a waste. Composter, because of the decomposition process that this activity implies, stabilizes constituents of residual materials. The organic waste remains resources, which is not the case for landfill waste in a site.
For example, 450 grams (1 lb) of organic matter buried in a dump (which breaks down without oxygen) produce 3 meters cubes (10 cu. ft.) of biogas, especially methane, one of the main gases responsible
of the greenhouse effect. During the decomposition of materials organic acids are formed and when they come in contact with the heavy metals and other dangerous compounds, like the dirty oils they
get to dissolve them. These leaching waters are a source of significant pollution.
In addition, the transportation of these thousands of tonnes of organic waste (1,228,000 metric tonnes annually) represents 49,120 garbage trucks walk in the streets of Quebec and that involve wasting fuel, not to mention the wear and tear of roads and trucks.
But what are these leaching waters?
In a landfill, the water contained in the decaying tailings flows, bringing with it the mineral and organic compounds of all residues in the dump. To this liquid is added the rain which, infiltrating, also takes care of acids resulting from the decomposition of materials organic. The very nature of the decomposition process, namely acidification material, increases the amount of these compounds in the liquid that seeps to the bottom of the site. It’s this sauce that flows from the sites we call leachate. Leachate can contaminate groundwater and water bodies around sites. Some of the inorganic and organic compounds present in leachate can be very toxic to the surrounding flora and fauna and may result in serious disorders in neighboring ecological systems, eliminating the necessary for the life of certain species.
In addition, because landfills are full of nutrients, attracts rats and some birds that can also contribute to pollution of the environment through the transmission of pathogenic viruses. Thus, the possibility to spread diseases to living beings in the surrounding area increases, both for animals than for humans.
What are these biogas?
The decomposition of fruits and vegetables, garden residues, and any matter can decompose by microorganisms under anaerobic conditions (in a landfill, without oxygen) produces biogas. It’s about of a mixture of different gases dominated mainly by methane and carbon dioxide as well as hydrogen sulfide and some compounds volatile organic compounds. These gases can represent a real danger to health and the safety of the population and generate very unpleasant odors if the site is badly managed. Dangerous why? Because these gases are flammable and can participate in the greenhouse effect.
