The Value Of Compost For Soil Improvement
In recent years, the word "green product" has gained popularity rapidly, and consumers' desire to eat "safe food that is safe to eat" has become increasingly louder. Organic farming, which produces green food, has gained such prominence because of the heavy use of fertilisers and pesticides that have dominated modern farming since the second half of the 20th century.
The spread of chemical fertilizers has led to a great decline in organic fertilizers, followed by a decline in arable land, as well as a great impact on the quality and yield of agricultural products.The agricultural products produced in the land without land resources are not healthy and prone to pesticide residues and other problems, losing the original taste of crops.With the improvement of people's living standards, these constitute an important reason for consumers to need "safe and delicious food".
Organic farming is not a new industry.Before the introduction of fertilizer, it was common agricultural practice everywhere, especially in China, where compost is more than 4,000 years old.In the meantime, organic agriculture, dominated by composting, kept the land healthy and productive, but it was destroyed by modern agriculture, dominated by fertilizer, in less than 50 years, which led to the serious situation we have today. In order to overcome this serious situation, we should learn from history and combine modern science and technology to construct a new type of organic agriculture, so as to open up a sustainable and stable agricultural development.
Chemical fertilizer and Compost
Fertilizer has the characteristics of multiple fertilizer ingredients, high fertilizer efficiency and quick efficiency. Additional, the product with good treatment is convenient use, and a few can, labor burden is small also, advantage it may be said is great.The disadvantage of this fertilizer is that it contains no organic humus.
And although compost is generally said to be a fertilizer with little composition and late effect, its advantage is that it contains humus, amino acids, vitamins, trace elements and other substances to promote biological development, which are the elements that constitute the characteristics of organic agriculture. The active ingredients of compost are what are produced when organic matter is broken down by microorganisms, and these ingredients are absent from inorganic fertilizers.
The advantages of compost:
At present, the residues, excreta, household garbage and other "organic wastes" from human society are huge, which not only causes the waste of resources, but also brings huge social problems.Most of them have been burned or buried as useless garbage, which has turned into major causes of air pollution, water pollution and other public hazards, causing immeasurable harm to the society.
The composting treatment of these organic wastes has the possibility to solve the above problems fundamentally.History tells us that "all organic matter from the earth returns to the earth", which is the most consistent with the cycle of nature and beneficial to human beings.
Only when the "soil, plants, animals, human" these four constitute a healthy biological chain, to ensure human health.Only when the environment and health conditions are improved can the benefits to human beings be extended to future generations.
