Back in antiquity, Aristotle called the bowels of the earth, but it took several centuries to earthworms systematically studied "by Charles Darwin, who wrote an entire book on the importance of worms in the layer of dead organic matter, improve the soil structure and soil aeration, drainage and fertility. Darwin calculated that earthworms in the soil add about eleven tons of organic matter per hectare (around 18 tonnes per hectare) per year, scholars Modern believe that is true in the abundance of worms can increase to 250 tonnes per hectare per year. According to Darwin, earthworms have an acid reaction in the upper digestive tract of soil and organic matter that affects the channel. calcium in their intestinal glands secrete carbonate of lime, slowly neutralize the acid particles and, finally, changing the response to alkaline soils, and traffic reaches the lower digestive tract. earthworms for food, carbon-nitrogen organic material gradually decreases. nitrogen becomes most useful forms of ammonium and nitrate, phosphorus, potassium and other nutrients are converted into forms readily available. As several mineral and organic particles pass through the earthworm's digestive tract, get very close to the mixed aggregates, drainage and soil moisture capacity is improved. The organic-mineral aggregates have plenty of water for stability and the strengthening of other soil characteristics. Some researchers believe that up to 50% of aggregates found in the surface layers of soils derived from earthworms. In addition to the aggregates, earthworms also play an important role in the formation of the soil, improving the structure and improve soil physical characteristics. Modern agriculture products using earthworms in different ways. vermiculture vermiculture the term also refers to the production of humus from organic matter by using a combination of microorganisms and earthworms land. Unlike other processes of composting, worm composting does not require heat to degrade and stabilize organic matter, replacement, makes use of the intimate interaction between worms and microbes that live in your intestinal tract and the organic material. vermiculture are two products of economic value, issued and vermi-vermi meal. Casts is to decompose the organic waste material, mucus substances and nitrogen derivatives. The texture of these models are thinner than can be found in traditional waste composting. Vermi cast is superior to inorganic fertilizers in their ability to provide nutrients for growth. In addition to normal NPK (nitrogen, phosphorus and potassium) content, vermi cast provides enzymes, beneficial microorganisms, and growth hormones. Vermi meal is a meal rich in proteins from earthworm hamburger. The protein content is approximately 62% to 11% fat. Can be used as a feed ingredient. Worm Juice Worm Juice is a special product of earthworms. It also contains a series of NPK, but the big advantage comes from the abundance of nitrogen-fixing bacteria (about 100,000 CFU / ml), trace elements and minerals, all mixed into one and aerated liquids immediately available to the plant. Usually applied to the rate of 10 liters per hectare, the worm juice helps the land back to its natural ability of plants to provide the nutrients they need in a readily available. Also used as a foliar spray and seed, as coatings to increase germination. The worm compost tea also known as worm tea, this nutrient solution is a liquid form of vermi cast of vermicompost, rich with minerals, essential nutrients, and all the different micro-organisms is necessary to improve soil health and plant growth. The application is simple, but it is important to activate the worm tea applied within 4 hours after the solution. Worm tea is usually applied to the soil, leaves and mulch the ground in the promotion of health. Continued use of earthworms and products of earthworms help to inorganic fertilizer and other chemicals to eliminate in your company.
