#Agricultural Technology Science Popularization Competition # At a time when international fuel prices are soaring, domestic agricultural diesel prices are also rising rapidly, which is very unfavorable to rural machine farming machine sowing, increasing the cost of agricultural machinery farming, compressing the profit margin of farmers farming, and reducing economic income.
Therefore, many people in rural areas, in order to reduce machine farming, save fuel for machine farming, and reduce the cost of machine farming, in order to improve their planting income. Therefore, farmers are always looking for no-till technology for farmland, borrowing from other people's advanced technology and experience, but it is always difficult to find.
Recently, according to media reports, no-till is widely used in Argentina and Latin American countries to grow farmland. Argentina is the most prominent country, with 80% of the land being cultivated using no-till. Argentina's use of this no-till method has not only led to a reduction in crop yields, but has also seen a significant increase in yields.
This no-till method of planting, the land is not ploughed for a long time, after the harvest of crops, the straw is not burned, nor is it put away and disposed of separately, but is cut down, crushed and spread in the farmland. In this way, the straw is covered on the surface of the soil, natural decay and weathering, and a loose and softened tillage layer of 5 to 10 cm will be formed in the surface layer of the soil, which not only retains water but also has rich humus, making the cultivated land more fertile and ventilated, which is conducive to the growth of crop roots.
Cultivating such a soil force does not need to plough the land for a long time, and the land is not compact at all, but it is very loose and softened, and the reproduction of weeds is also reduced. Even with weeds, weeding is very easy, either mechanically or medicated.
After harvesting, the next stubble sowing, are the use of mechanical operations, crushed straw, by the machinery pushed open a gap, the soil, and then sown on the soil, do not have to worry at all, the seed does not fall into the soil and affect the germination and growth.
This no-till method mainly relies on straw return to the field, so that finely broken straw covers the soil, forming a protective layer, and under the action of a very large beneficial microbial population, to decompose the straw, create nutrients, cultivate soil, provide crops with rich nutrient substances, and reduce the amount of fertilizer.
Since the straw is covered in the soil and there is a large population of beneficial microorganisms, it is possible to inhibit the multiplication of harmful bacteria and reduce many diseases. This no-till method greatly reduces the pests and diseases of crops, which can save many pesticides and fungicides and reduce planting costs.
This no-till method of planting is to make full use of straw return as a support to cultivate beneficial microbial communities to prevent diseases and insects, and to achieve the purpose of loosening and softening the soil. This is the core part of the Argentine agricultural no-till method technology, which is worth learning and learning from farmers.
In Latin America, that is, in central America, in addition to Argentina, there are also agricultural countries such as Paraguay, Uruguay, Brazil, Chile and so on, all of which use this no-till method of cultivation. No-till farming methods are widely used in these areas, with some countries accounting for about 90 per cent of the land. This no-till planting technique not only reduces the cost of agricultural production, but also frees farmers from heavy physical labor, the labor intensity is greatly reduced, and it can also increase grain production and agricultural income.
All in all, this no-till planting technology in Argentina not only saves the cost of agricultural machinery ploughing, but also makes full use of straw for returning to the field, cultivates beneficial microbial groups, reduces pests and diseases, makes the soil more fertile, the land is more loose, is conducive to the growth of crops, reduces the use of fertilizers and pesticides, and can also retain moisture and water, prevent the harm of drought, save labor, save planting costs, improve crop yields, and increase the economic income of planting. The benefits of this method are very many, and it is worth learning and using for farmers.
