Organic fertilizers include all substances that can be used as fertilizer except fertilizers. They are usually human and animal waste, crop straw, and green manure. Organic fertilizer has comprehensive nutrients and a long-lasting and balanced fertilizer effect. It can improve soil structure, fertility and fertility, and promote the release of soil nutrients. It is particularly important for the development of organic agriculture, green agriculture, and pollution-free agriculture.
Human waste
Human fecal urine has a high nutrient content, and storage is mainly leak-proof, nitrogen-preserving, and harmless. First of all, it is necessary to transform the toilets. The bottom and all sides of the toilet storage tanks should be treated with anti-seepage treatment, and the top should be shaded. The second is to add soil to protect nitrogen, add fine soil in a ratio of 1:3 to 4, and store in situ. The third can produce high-temperature composting, stacking excreta and straw, killing germs and eggs, and applying them to maturity.
Human feces and urine are suitable for use in leafy vegetables, cereals and fiber crops. They should not be applied to tobacco crops such as tobacco, potato, sugar beet, etc., nor should they be applied to saline-alkali soils.
Fertilizer
The fertilizer composted by pigs, horses, cattle, sheep and other large livestock excreta and various gasket materials is collectively referred to as manure. Fresh manure will need to be accumulated and matured for a period of time before it can be used. It is suitable for various soils and crops, and the accumulation process is centered on nitrogen conservation. The first is to time the washers, ring in time, the choice of materials fine soil or firewood, soil washers, dirt ratio 1:3 to 4. The second is that when it is ready for use, it should be compacted and sealed with mud. The third is to avoid the use of alkaline ash and other material gaskets to prevent nitrogen from evaporating. After the maturity, the manure can be used as seed fertilizer, topdressing fertilizer, and base fertilizer before planting; in the sandy soil, the manure with poor maturity should be used. Each time it is not appropriate to measure more, deeper application is required; in the viscous soil, the degree of maturity should be better The fertilizer can be used more often, but it should be applied lightly.
compost
Compost is a fertilizer made from straw, weeds, garbage and other raw materials plus a certain percentage of human waste, urine and feces, etc. It is a fertilizer made by composting under the action of microorganisms. It is a high-quality fertilizer containing a lot of organic matter and is suitable for each Crops and soil.
(a) High-temperature compost production technology
1, in the summer, the lee at the shadowy place to dig round rectangular rectangular pit, deep 100 cm, depending on the size of the material, depending on the amount of rot, the removed soil in the pit to do squat, 70 to 100 cm above the ground. At the bottom of the pit, dig trenches with a depth of 20 cm and a width of 20 cm each were used to connect the pit wall to the ground.
And use straw to lay a vertical layer on it and keep the ventilation ditch in communication with the ground space.
2, the ratio of materials for composting. 500 kilograms of straw, 300 kilograms of manure, 100 to 200 kilograms of human waste, and 800 to 1,000 kilograms of water.
3, cut the straw into 5 to 6 centimeters long, spread 60 to 70 centimeters thick rectangular heap, spread all kinds of materials evenly, and then water from the side of the stack side, fully mix, will mix the material Put it in the pit, up to the soil, and seal it with soil.
4, generally a few days after the stack temperature can reach 70 °C or more, until the pile after the temperature drop, break the material, fully overturned, re-stacking, generally tipping 3 to 4 times, about 30 days can be decomposed and spared.
(B) "301" inoculum rapid rot straw technology
The "301" inoculum is a kind of high-temperature fungus with high rot. The organic matter of the compost straw is as high as 40.5%, and all kinds of nutrients are higher than those of common heap manure. It is a kind of organic fertilizer with full efficiency and high quality.
1. Select the leeward shade, dig a width of 150 cm, and a depth of 20 cm in the earth pit, depending on the amount of straw, and dig out the soil to repair the soil.
2, material ratio. For every 1,000 kg of straw, add 5 kg of "301" inoculum and 5 kg of urea (or 50 to 100 kg of fresh excrement).
3, cut the straw into 30 cm long sections, fully absorb the water, build a heap, step with the heap, water 60 cm high when watering, sprinkle the first layer of bacteria and urea (or human waste), the amount of 50%, and then When the straw is piled 120 centimeters high, it is irrigated with water, sprinkled with the remaining bacteria and urea, and piled up to 150 cm high.
4, fertilizer heap with 4 to 6 cm thin mud shading seal, plus cover film, 15 to 20 days or so turn a heap, pouring water tight seal.
5, after fermentation for a period of time, take a small amount of fertilizer from the side, if it has been black rot that has been cooked, can be applied.
Although organic fertilizers have many advantages, they are low in nutrient content, have a large amount of fertilizer, and are slow in fertilizer efficiency. Therefore, in order to obtain high yields and improve fertilizer efficiency, organic fertilizers and chemical fertilizers must be used in combination to complement one another and be suitable for each other.
A urinalysis is a test of your urine. A urinalysis is used to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease and diabetes. A urinalysis involves checking the appearance, concentration and content of urine.Clinical urine tests are various tests of urine for diagnostic purposes. A urinalysis is one of the most common methods of medical diagnosis. The word is a portmanteau of the words urine and analysis. Other tests are urine culture and urine electrolyte levels.
