Question

На какие группы можно разделить все удобрения. Значения этих удобрений и примеры. Помогите плиз

Answer 1

Ответ:

Деление их на виды происходит:

двойные (азотно-фосфорные, азотно-калийные, фосфорно-калийные) комплексные удобрения;

тройные (азотно-фосфорно-калийные) комплексные удобрения

Удобрения улучшают развитие надземной вегетативной массы растений. Под влиянием удобрений лучше развивается корневая система растений, связывающая почву. Примеры органических удобрений: Навоз, Солома, Торф и торфяные компосты, Сухой птичий помет, Коровяк. ... Значение его для удобрения сельскохозяйственных культур огромно.

Groups of Fertilizers

Fertilizers can be divided into several groups based on their composition and purpose. The main groups of fertilizers include:

1. Organic Fertilizers: These fertilizers are derived from natural sources, such as animal manure, compost, and plant residues. They provide essential nutrients to plants and improve soil structure and fertility. Organic fertilizers release nutrients slowly over time and promote long-term soil health.

2. Inorganic Fertilizers: Also known as synthetic or chemical fertilizers, these are manufactured using chemical processes. Inorganic fertilizers are typically composed of concentrated nutrients, such as nitrogen (N), phosphorus (P), and potassium (K). They provide immediate nutrient availability to plants and are often used to address specific nutrient deficiencies in the soil.

3. Complete Fertilizers: Complete fertilizers contain a balanced combination of the three primary nutrients: nitrogen (N), phosphorus (P), and potassium (K). They are formulated to provide a well-rounded nutrient supply for plants. The ratio of these nutrients may vary depending on the specific needs of different plants or crops.

4. Specialty Fertilizers: Specialty fertilizers are designed for specific purposes or crops. They may contain additional nutrients or additives that cater to the unique requirements of certain plants. Examples of specialty fertilizers include those formulated for acid-loving plants, orchids, or specific types of vegetables.

5. Slow-Release Fertilizers: These fertilizers are designed to release nutrients gradually over an extended period. Slow-release fertilizers provide a sustained nutrient supply to plants, reducing the risk of nutrient leaching and ensuring long-term plant health. They are particularly useful in situations where frequent fertilization is not practical or desired.

6. Liquid Fertilizers: Liquid fertilizers are formulated as liquid concentrates that can be diluted with water and applied directly to plants or soil. They are quickly absorbed by plants and provide an immediate nutrient boost. Liquid fertilizers are often used for foliar feeding or as a supplement to regular soil fertilization.

Examples and Benefits

Here are some examples of fertilizers from different groups and their benefits:

1. Organic Fertilizer Example: Compost is a common organic fertilizer made from decomposed organic matter. It enriches the soil with nutrients, improves soil structure, enhances water retention, and promotes beneficial microbial activity.

2. Inorganic Fertilizer Example: Urea is a widely used nitrogen-based inorganic fertilizer. It provides a readily available source of nitrogen to plants, promoting leaf and stem growth. Urea is often used in agricultural settings to increase crop yields.

3. Complete Fertilizer Example: 10-10-10 is a balanced complete fertilizer that contains equal proportions of nitrogen, phosphorus, and potassium. It provides a well-rounded nutrient supply for various plants and can be used in gardens, lawns, or potted plants.

4. Specialty Fertilizer Example: Citrus Fertilizer is a specialty fertilizer formulated specifically for citrus trees. It contains additional nutrients like iron and magnesium, which are essential for healthy citrus growth and fruit production.

5. Slow-Release Fertilizer Example: Polymer-Coated Urea is a slow-release fertilizer that gradually releases nitrogen over time. It provides a sustained nutrient supply to plants, reducing the risk of nutrient loss and optimizing nutrient uptake.

6. Liquid Fertilizer Example: Fish Emulsion is a liquid organic fertilizer made from fish waste. It is rich in nutrients like nitrogen, phosphorus, and potassium, and is quickly absorbed by plants. Fish emulsion is often used as a foliar spray or soil drench to promote healthy plant growth.

Remember, the choice of fertilizer depends on factors such as the specific nutrient requirements of the plants, soil conditions, and the desired application method. It's always a good idea to consult local gardening experts or agricultural extension services for specific fertilizer recommendations based on your needs.
