Vermi-composting uses earthworms to produce compost from organic residues. Earthworms can practically eat all kinds of organic matter. The following are the guidelines for preparing a good quality vermi-compost.
Monoammonium phosphate (MAP) is a widely used fertilizer that provides essential nutrients to plants, particularly nitrogen and phosphorus. Here are some key points about monoammonium phosphate:
Nutrient Composition: MAP is composed of ammonium ions and phosphate ions.
It contains both nitrogen and phosphorus, making it a valuable fertilizer for promoting plant growth.
Solubility: Monoammonium phosphate is highly water-soluble, allowing for easy application as a liquid fertilizer or in irrigation systems.
pH: MAP tends to be slightly acidic, which can contribute to lowering the pH of the soil. This can be beneficial in alkaline soils or for crops that prefer slightly acidic conditions.
Fertilizer Use: It is commonly used in agriculture as a source of both nitrogen and phosphorus.
The ammonium nitrogen in MAP is readily available for plant uptake, while phosphorus is crucial for root development, flowering, and fruiting.
Application: MAP is often used as a granular fertilizer that can be broadcast on the soil surface.
It can also be dissolved in water and applied as a liquid fertilizer.
Compatibility: MAP is generally compatible with other fertilizers, and it can be used in combination with them to provide a broader spectrum of nutrients.
Uses in Different Crops: MAP is suitable for a variety of crops, including grains, fruits, vegetables, and legumes.
It is particularly useful for crops that require a balanced supply of nitrogen and phosphorus during their growth stages.
Storage: Monoammonium phosphate (MAP) should be stored in a cool, dry place to prevent moisture absorption and caking.
Environmental Impact: Like other fertilizers, the application of MAP should be done responsibly to minimize environmental impact, such as nutrient runoff into water bodies.
Safety Considerations: When handling MAP, it's important to follow safety guidelines and use appropriate protective equipment to prevent skin or eye contact and inhalation.
Vermiwash is rich in dissolved nutrients and amino acids which are easily obtainable for plants. It is a non-toxic and eco-friendly compound, which arrests the bacterial growth and forms a protective layer for their survival and growth
Diammonium phosphate (DAP) is a widely used fertilizer that provides a high concentration of phosphorus and nitrogen nutrients. It is composed of two ammonium ions and one phosphate ion. DAP is a water-soluble salt and is often used in agricultural settings to enhance plant growth. Here are some key points about diammonium phosphate:
Nutrient Composition: Diammonium phosphate is a good source of both nitrogen and phosphorus, with nitrogen content in the ammonium form and phosphorus in the phosphate form.
The nitrogen in DAP is readily available for plants, while phosphorus is essential for root development, flowering, and fruiting.
Solubility: Diammonium phosphate is highly water-soluble, making it easy to apply as a liquid fertilizer or to dissolve in irrigation systems.
pH and Acidity: DAP tends to be slightly acidic, which can contribute to lowering the pH of the soil over time. It is essential to monitor soil pH when using fertilizers to prevent overly acidic conditions.
Application: DAP is commonly used as a dry granular fertilizer that can be broadcast on the soil surface.
It can also be dissolved in water and applied as a liquid fertilizer through irrigation systems, providing quick nutrient availability to plants.
Uses: Diammonium phosphate is suitable for a variety of crops, including grains, fruits, vegetables, and legumes.
It is often used during the early stages of plant growth to promote root development.
Storage: DAP should be stored in a cool, dry place to prevent moisture absorption and caking.
Safety Considerations:
When handling DAP, it's important to follow safety guidelines and use appropriate protective equipment to prevent skin or eye contact and inhalation.
Compatibility: Diammonium phosphate is compatible with many other fertilizers and can be used in combination with them to provide a broader spectrum of nutrients.
Environmental Impact: Like other fertilizers, the application of DAP should be done responsibly to minimize environmental impact, such as nutrient runoff into water bodies.
Properties of urea
Urea, also known as carbamide, carbamide and urea. Pure urea is white, tasteless, odorless, needle shaped or prismatic crystal, with a melting point of 132.7 �¢?? under normal pressure. It is hygroscopic, deliquescent, hydrolyzable, and weakly alkaline. It is made into compound fertilizer with acid fertilizer. Urea is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal. Urea is one of the simplest organic compounds. The most important use of urea is as fertilizer. Its nitrogen content is more than 46%. After being converted into ammonium carbonate in soil, urea is hydrolyzed and absorbed by plants. It is the nitrogen fertilizer with the highest nitrogen content at present.
Molecular formula of urea: CO (NH2) 2, molecular weight 60.06, density 1.335g/cm �?�³�¯�¼? The melting point is 132.7 �¢??. Soluble in water and alcohol, insoluble in ether and chloroform. It is slightly alkaline. It can react with acid to form salt. It has hydrolysis. Condensation reaction can be carried out at high temperature to produce biuret, triuret and cyanuric acid. Heat to 160 �¢?? and decompose to generate ammonia gas and turn into cyanic acid at the same time. Urea can be hydrolyzed into ammonia and carbon dioxide under the action of acid, alkali and enzyme (acid and alkali need to be heated). Unstable to heat, heat to 150 �¢??�¯�½? 160 �¢?? to deamination to biuret. Urea is easily soluble in water, 105g can be dissolved in 100ml water at 20 �¢??, and the aqueous solution shows neutral reaction. There are two kinds of urea products: crystalline urea is white acicular or prismatic crystal with strong hygroscopicity; Granular urea is a translucent particle with a particle size of 1~2mm, which has a smooth appearance and improved moisture absorption.
Urea is a physiologically neutral fertilizer, which does not leave any harmful substances in the soil and has no adverse effects after long-term application. However, a small amount of biuret, also known as biuret, will be produced when the temperature is too high during granulation, which has an inhibitory effect on crops. Urea is molecular before conversion and cannot be adsorbed by soil, so it should be prevented from being lost with water; The ammonia formed after conversion is also volatile, so urea should also be deeply covered with soil. Urea is the first synthetic organic substance and widely exists in nature, such as 0.4% urea in fresh human feces.
The new version of national standard GB/T2440-2017 for urea has been officially implemented since July 1, 2018. Compared with the replaced 2001 standard, certain adjustments have been made.

Urea, also known as carbamide, is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen. It is a white crystal and one of the simplest organic compounds. It is the metabolic decomposition of protein in mammals and some fish. The main nitrogen-containing end product is also the nitrogen fertilizer with the highest nitrogen content.
As a neutral fertilizer, urea is suitable for various soils and plants. It is easy to store, easy to use, and has little damage to the soil. It is a chemical nitrogen fertilizer that is currently used in a large amount. In industry, ammonia and carbon dioxide are used to synthesize urea under certain conditions.
Agricultural applications:
Urea is a high-concentration nitrogen fertilizer, a neutral quick-acting fertilizer, and can also be used to produce a variety of compound fertilizers. No harmful substances remain in the soil, and long-term application has no adverse effects.
Animal husbandry can be used as feed for ruminants. However, excessively high temperature in granulation will produce a small amount of biuret, also known as biuret, which has an inhibitory effect on crops.
my country stipulates that the content of urea biuret used in fertilizers should be less than 0.5%. When the biuret content exceeds 1%, seed fertilizer, seedling fertilizer and foliar fertilizer cannot be used, and the urea content in other application periods should not be too much or too concentrated.
Urea is an organic nitrogen fertilizer. After being hydrolyzed into ammonium carbonate or ammonium bicarbonate by the action of urease in the soil, it can be absorbed and utilized by crops. Therefore, urea should be applied 4 to 8 days before the fertilization period of the crop.
