Potassium nitrate is usually called pyronitrate. It is recrystallized from sodium nitrate and potassium chloride or extracted from nitroso. Its molecular formula is KNO3. It contains 13% N and 46% K2O. Pure potassium nitrate is white crystal, crude product is slightly yellow, hygroscopic, soluble in water, chemical neutral, physiological neutral fertilizer. It is easy to explode at high temperature and belongs to flammable and explosive substances.

It is suitable for dry land, generally 5-10 kg / 667 m2. It has a good effect on potato, tobacco, beet, grape, sweet potato and other crops that prefer potassium rather than chlorine frost. It has a good response in legume crops. If it is used for other crops, it should be combined with element nitrogen fertilizer to improve fertilizer efficiency. Potassium nitrate can also be used as root topdressing, and the suitable concentration is 0.6% – 1%. In arid areas, it can also be applied with organic fertilizer, the dosage is about 10kg / 667m2.
As the N: K2O ratio of potassium nitrate is 1:3.5, the content of potassium is higher, so the calculation of fertilizer should be based on the content of potassium.

In the complete set of equipment required for biological fertilizer production, fermentation stacker has gradually become a convenient tool to replace labor and forklift to deliver materials, and is the mainstream product of composting development trend with important influence.

According to the characteristics of organic fertilizer dumper, the characteristics used in composting production are: when making fertilizer, the dumper needs to adjust the carbon nitrogen ratio, pH and water content of raw materials, and some auxiliary materials must be added. add to. Depending on the lathe, the main raw materials and various auxiliary materials which are roughly stacked together in proportion can be evenly mixed to achieve the ideal granulating effect suitable for the granulator.

In the traditional stacker operation, the raw material particles are fully contacted and mixed with the air, and a large amount of fresh air can be cultivated in the stacker, which helps the aerobic microorganisms to produce spontaneous combustion fermentation heat and increase the stacking temperature.

When the temperature is high, adding fresh air to the reactor can reduce the temperature of the chimney. It forms the shape of high temperature exchange, and all kinds of beneficial microorganisms develop and reproduce in the appropriate temperature range.

The stacker system can process the material into small lumps, make the dense material pile loose and elastic, and form the appropriate porosity to promote the entry of oxygen.
After proper moisture fermentation, the moisture content of organic fertilizer is less than 40%. In the fermentation process, the biochemical reaction will produce new water, and the consumption of raw materials by microorganisms will gradually release water as carrier.

Therefore, in the process of fertilizer production, the water content is reduced in time. In addition to the evaporation caused by heat conduction, the raw materials are shifted from the stacker to form a forced water vapor distribution.

Our new organic fertilizer manufacturing equipment includes transverse device, walking device and stacking steering device. The stacking turning device consists of two reducers fixed on the frame, which are connected to the corresponding reducers through couplings and fixed with spiral blades. The utility model has the characteristics of improving the fermentation rate, rapidly decomposing the compost, preventing the generation of peculiar smell, and shortening the fermentation time.

eIt is usually applied to: farm, fertilizer fermentation, fertilizer factory, brewery, food factory and sugar factory fermentation of raw materials in fermentation waste fermentation and sugar residue crushing.

Bio organic compost production line is a kind of compost which has the function of both microbial compost and organic compost. It is composed of specific functional microorganisms and organic matter, mainly used to remove plant residues (such as livestock manure, crop straw, etc.) After harmless treatment and decomposition.

The production method and operation process of bio organic compost are as follows:

1. The first step in the production process of bio organic compost: the total dosage of selected strains is 0.2% – 0.5%.
2. Production process of bio organic compost: preparation and requirements of raw and auxiliary materials:
3. Main ingredients: fruit residue, dry bagasse, edible fungus residue, distiller’s grains, sugar residue, vinegar residue, starch residue, cassava residue, citric acid residue, soy sauce residue, monosodium glutamate residue, powder residue, bean curd residue, drug residue, oil residue, oil cake, bran, cottonseed meal, moldy feed, sludge, brewery’s residue, slaughterhouse residue, Ho water (s water), Leftover food, human and animal manure and other materials.

1. Auxiliary materials: all kinds of crop straws, leaves and weeds, melons and vines, straw, pine hull, peanut hull, sawdust, rice husk powder, rice bran, etc. can be dried, crushed and made into high carbon.
2. The proportion of main materials and auxiliary materials is 5:1-3:1.
3. The production process of bio organic compost production line is divided into three steps: the water content should be controlled at 60-65%, and the water can only come out by hand holding materials in groups. Bacteria, main materials and auxiliary materials should be mixed evenly. The ambient temperature should be higher than 15 ℃. The stacking area of materials shall not be less than 4 square meters, the width shall be 1.5-2 meters, the height shall be 0.6 meters, and the length shall not be limited.
4. The production process of bio organic compost is divided into four steps: composting should be turned at 50 ℃ once a day. If the chimney temperature exceeds 65 ℃, it will be overturned again. The temperature will be controlled below 70 ℃. The temperature of composting will be lower, the material will be loose, the material will not have the original smell, and there will be a little ammonia smell. White hyphae are produced in the pile and decompose.

Organic fertilizer production equipment should be kept in daily use to extend its service life. Let’s take a look at the skills of maintaining the organic fertilizer production equipment:

1. Keep the work site clean. After each experiment on the organic fertilizer manufacturing equipment, the particle leaves and residual mortar inside and outside the granulating pot should be cleaned, and the mortar and flying objects falling on or scattered on the organic fertilizer equipment should be cleaned. Wipe the exposed processing surface clean, apply anti rust meat paint, and cover the corresponding protective cover to prevent the second invasion of dust.

Pan Granulation Compound Fertilizer Production Line

2. There is no external oil filling hole for the organic fertilizer equipment needed for the production of biological fertilizer, and the gears and worm gears are lubricated with special grease for the organic fertilizer equipment. Top and bottom should be triple buttered every season. When refueling, the dynamic transmission cover and the transmission cover can be opened respectively.

The lubricating oil should drip into the sliding surface of the supporting gearbox and the hinge joint of the bracket frequently. The worm gear box and bearing are filled with enough transmission grease at the factory, but the machine of the gear box should be cleaned and all protective lubricants should be replaced after using once a year.

3. Always pay attention to the operation of organic fertilizer machine. There should be no serious abnormal sound or metal friction sound. If any abnormality is found, please stop using immediately and check. Use it after troubleshooting. No corresponding check was found. Cause the machine cannot be started.

If there is metal friction sound, please first check the clearance between the granulator and the granulator blade of the organic fertilizer equipment.

4. Regularly check the standard clearance between granulating pans.

5. When replacing the pelletizing pot or blade of organic fertilizer barrel, the working clearance should be re measured and adjusted for many times. It can only be used after meeting the standard.

6. If it is impossible to operate the organic fertilizer machine by pressing the program controller, please check whether the power supply voltage, power plug and socket, connecting plug and socket are normal, and check the internal fault of the controller.

The above is the maintenance work of the organic fertilizer equipment we introduced. Only by doing this, can the service life of the equipment be extended, and the equipment be used more smoothly. More detailed info go to https://organicfertilizerplants.com/

The process of compost production in the production of biological compost.

(1) The mixture of strains based on microbial fermentation was prepared.

In order to produce bio organic compost, the fermentation substrate must be used as the strain. We use HM fermentation base here. In order to make more evenly contact with chicken manure, 10 kinds of beneficial microorganisms, such as nitrogen fixing bacteria, nitrogen fixing bacteria, potassium decomposing bacteria, phosphate decomposing bacteria, yeast, actinomycetes, Bacillus Giganticus and Bacillus subtilis, are more evenly contacted with chicken manure, and 100g HM fermentation base material is divided into five equal parts. Every 20 grams, about 1-1.6 kg wheat bran or soybean meal and soybean meal are added to each HM fermentation base Other auxiliary materials, which are well mixed, are called plants. In this way, each bacterial mixture can ferment about 200 kg of chicken manure.

(2) Two manufacturing methods:

The production of bio organic compost used in livestock and poultry manure can be divided into static processing and dynamic processing.

Bio compost production line

1. static processing and manufacturing technology of bio organic compost:

Static treatment of bio organic compost is a kind of self-made bio organic compost produced by farmers in the field. The method is simple, easy to operate, and has less investment, which is suitable for small-scale professional farmers.

(1) Prepare chicken manure and accessories.

Choose an open space of about 30 square meters, flat ground, no water, and separate chicken manure from auxiliary materials.

In order to mix the mixture of strain and chicken manure evenly, we divided 1000 kg chicken manure into five equal parts. About 200 kg per serving.

Pan Granulation Compound Fertilizer Production Line

Generally, the grain or powder wheat bran, peanut shell powder and other main auxiliary materials, such as corn straw, cotton stalk, etc., must be cut into 5-10 cm long, too long will cause inconvenient mixing. The purpose of adding auxiliary materials is to regulate the water content and carbon nitrogen ratio of chicken manure and improve the permeability of fermentation materials.

(2) Fermentation platform construction.

After chicken manure and auxiliary materials are ready, fermentation platform shall be built according to the actual situation of environment and farmers.

When establishing fermentation platform, please select places with sufficient sunshine, flat, high terrain, avoiding opening of air outlets and easy to operate. First, some parallel ventilation ditches are excavated, with the width of 30 cm, depth of 30cm and width of ditch beam of 20cm. The branches, bamboo strips, straw and so on are spread on the ditch beam to form a fermenting platform with permeable bottom, which is convenient for ventilation and oxygen supply. Because the beneficial biota in HM fermentation base belongs to aerobic strain, the fermentation products can decay better only when there is enough oxygen.

After the fermentation platform is completed, we can continue to produce the bio organic compost which is still processed.

(3) Operation steps.

Evenly spread the mixture of the strain on the prepared chicken manure and mix well. During the mixing process, the moisture content of chicken manure should be adjusted to about 60%, namely holding several chicken manure in hand, holding tightly, and paying attention to the water between fingers, but not dripping water. Release your hand and gently touch to expand it. That’s enough water. If the water content is too high, add wheat bran, corn straw and other auxiliary materials to reduce the water content in chicken manure; if the water content is too low, add fresh chicken manure or sprinkle some water. Pile the mixed chicken manure on the fermentation platform.

The other four piles of chicken manure were treated in the same way, all piled together. At this time, the height is about 1-1.2m, the length and width are 1.5-2 meters, and the composting amount is generally 1.5 cubic meters.

(4) Management of fermentation process.

In the process of fermentation, temperature control is very important. If the temperature is too low, the mature standard cannot be met; if the temperature is too low, it cannot be reached. If the temperature is too high, the nutrients of compost are easy to lose. The temperature inside compost is from outside to within 30 cm. Therefore, the metal rod of thermometer used for measuring temperature must be longer than 30 cm. When measuring, it must be inserted into compost for more than 30 cm to accurately reflect the fermentation temperature of compost.

Fermentation temperature and time requirements:

After composting, chicken manure entered the first fermentation stage. It will automatically heat to above 55 ° C for 5 to 7 days, and then kill most parasite eggs and harmful bacteria to be harmless

Some odor will be produced during composting, so odor control procedures should be included in the planning, design and operation of composting facilities. These odors mainly come from three sources: odorous raw materials, ammonia released from high nitrogen materials, and composting and anaerobic conditions in composting. But raw materials with strong odors can cause most odors. Sewage sludge and animal manure usually produce peculiar smell. By using organic materials composting equipment as soon as possible and maintaining aerobic conditions, odor can be minimized.

The following recommendations will help to minimize odour:

• Make a good formula of raw materials and keep the raw materials mixed well
• Store raw materials as quickly as possible
• Keep the reactor height about 4 – 1 / 2 feet
• Keep the pile humidity about 55%
• Prevention of puddles and ponding (anaerobic activity pool)
• Minimize dust (with odor)
• Keep the stack dry
• Keep the equipment clean (compost will become anaerobic)

Quality and end use of compost

In general, the following parameters are used to indicate compost quality:

• pH（5.5 – 7.5）
• Soluble salts (< 5 mmhos / cm)
• Nutrients
• Water holding capacity
• stability
• Organic matter content
• Moisture content (35% – 55%)
• Grain size (3 / 8-1 in)
• Bulk density (< 1000 lbs / Cu YD)

The composting quality criteria for these parameters vary according to the end-user specifications. For example, it is recommended that the diameter of compost used as plant top fertilizer should be less than 1 / 4 inch. Composts less than 1 / 2 inch in diameter can be used for other purposes, such as soil amendments, potted media, or fine machining composting fertilizer to granules.

Aesthetic parameters, such as color and texture, are also important because people choose compost products mainly based on their appearance. For example, it is assumed that dark compost is better than light compost.

Compost can be used as a fertilizer mixed with soil, as topdressing for mulch, turf or other plants, as a modifier for growth mixtures, and as a mixture with topsoil. At present, the first use of compost is the planting bed. It is expected that compost will be widely used in field nursery production.

The benefits of mature compost on Soil and plants include:

• Improving soil structure
• Reducing fertilizer demand
• Improve water penetration and drought resistance
• Reduce soil compaction and crusting
• Improve root growth and yield
• Increase microorganisms in soil
• Protect plants from disease
• Slow release of nutrients to plants
• Improve nutrient capacity
• Increasing the difficulty of farming

Compost has also been shown to be useful for pollution prevention and remediation. It is used to prevent erosion on hillsides, embankments and roadsides. Composting can also combine with heavy metals in contaminated soil, degrade many pesticides, absorb odors and degrade volatile organic compounds. In addition, compost is also used to mitigate wetland damage, rainwater filtration and biofilter.
