Zero No-till technology, which originated in agriculture in the 19th century, is based on the abandonment of any field operations. In this case, after harvesting the previous crop, peeling, disking, processing, as well as plowing and loosening are not performed. With this approach, a cushion of plant debris collects on the surface of the earth.
This technology is one of the most resource-saving and soil-protective. No-till allows to protect the top layer of soil from wind and water erosion. A significant amount of plant residues on the earth's surface makes it possible to better retain and accumulate moisture. Resource savings are achieved by abandoning traditional processing methods.
There are currently more than 90 million hectares of land under zero cultivation worldwide. The rapid rise in energy prices in Latin America has forced agronomists to switch to such technology en masse. As a result, the local farm has taken a leading position in the world in terms of exports.
The main differences of the technology:
1. Larger seed drills are required for sowing. This saves fuel as well as people's working time.
2. When preparing, it is necessary to take into account the basic rule - the ground in the field should be as flat as possible. Only in this case, special drills will be able to demonstrate their maximum efficiency.
3. With regard to crop rotation, the main element of zero technology is the use of green manure to replace plowing.
4. Differences also apply to mulching. In classical agriculture, the stubble is burned, after which it is plowed into the ground, and the resin is collected. In the case of zero technology, stubble straw is used as mulch. The composition is evenly distributed over the field. This technique promotes the formation of a strong protective coating for the soil, as well as protects against the destructive effects of erosion - both water and wind. In general, this approach ensures the formation of favorable microflora in the soil.
This technology has proven its effectiveness compared to traditional processing. According to experts, No-till requires no more than 7% of investments from all technological costs. Such savings are due to lower fuel and wage costs. The use of zero technology will reduce the implementation time of all major tasks.
Advantages of No-till:
• a fairly efficient business model that promotes savings;
• increase in crop volumes in areas with insufficient moisture;
• the possibility of restoring the fertility of land;
• increasing the amount of humus content.
Today in the steppe regions of our country zero technology is used to cultivate 11% of the area. According to experts in the agricultural sector, traditional agriculture is now developing quite dynamically. Most agronomists are not yet ready to learn new technologies. Despite this, the increase in prices for technical and material resources, as well as the arid climate in the future will contribute to the growth of areas for this tillage technology.
A key disadvantage of No-till is the difficulty of crop rotation. Special equipment will be required to work with the soil. In addition, there are additional costs for the purchase of protective equipment for pre-sowing technology and after ladder treatment. We can help with the choice of drugs, calculations of norms and mixtures.
