Compound fertilizers are a type of plant nutrient that contains two or more essential elements required for plant growth and development. These fertilizers are often preferred by farmers and gardeners because they provide a balanced and complete nutrient profile, making it easier to meet the specific nutrient requirements of different plants. In this article, we will discuss the different types of compound fertilizers, their benefits, and how to use them.
Types of compound fertilizers
There are several types of compound fertilizers available, each with a unique nutrient profile and application method. Some of the most common types of compound fertilizers include:
NPK fertilizers: NPK fertilizers are the most widely used type of compound fertilizer. They contain a balanced blend of nitrogen (N), phosphorus (P), and potassium (K), which are essential macronutrients required for plant growth and development. The specific ratio of NPK in the fertilizer will depend on the specific needs of the plants being grown.
NP fertilizers: NP fertilizers contain a blend of nitrogen and phosphorus, which are essential for root development and flower and fruit formation. These fertilizers are often used for crops that require high levels of phosphorus, such as legumes, root vegetables, and fruit trees.
NK fertilizers: NK fertilizers contain a blend of nitrogen and potassium, which are essential for regulating water balance, increasing disease resistance, and improving stress tolerance. These fertilizers are often used for crops that require high levels of potassium, such as tomatoes, grapes, and citrus fruits.
NPKS fertilizers: NPKS fertilizers contain a blend of nitrogen, phosphorus, potassium, and sulfur, which is important for plant protein synthesis and the formation of amino acids. These fertilizers are often used for crops that require high levels of sulfur, such as onions, garlic, and other alliums.
Form of compound fertilizer
The compound fertilizers on the market are available in granular form and powder form.
- Granular compound fertilizer. Most of the large fertilizer manufacturers now use double roller granulator or drum granulators (also called Rotary drum granulator) to produce compound fertilizers with uniform particle size and high nitrogen content. High phosphorus and potassium content, long fertilizer effect period, easy to spread. The disadvantage is that the absorption is slow and the utilization rate is low. Long-term use will damage the soil and cause soil acidification, which will affect the growth of crops.
- The powder compound fertilizer mainly exists in the market as a water-soluble fertilizer with a large number of elements. Generally, this type of compound fertilizer has a complete content of trace elements, good water solubility, high absorption, and utilization rate, and the content of nitrogen, phosphorus and potassium is higher than that of granular fertilizers. compound fertilizer. The disadvantage is that it is not easy to spread, and the method of use is not as convenient as granular compound fertilizer.
Benefits of using compound fertilizers
Complete nutrient profile: Compound fertilizers provide a complete and balanced nutrient profile, making it easier to meet the specific nutrient requirements of different plants. This ensures that plants have access to all the essential nutrients they need for healthy growth and development.
Improved plant growth and yield: By providing plants with the essential nutrients they need, compound fertilizers can improve plant growth and yield. This can result in larger, healthier plants with higher fruit and vegetable yields.
Reduced fertilizer application: Since compound fertilizers contain a blend of essential nutrients, farmers and gardeners can reduce the number of fertilizer applications required. This can save time and money and reduce the risk of over-fertilizing, which can harm plants and the environment.
How to use compound fertilizers
Before using compound fertilizers, it is important to determine the nutrient requirements of the plants being grown. This can be done by conducting a soil test or consulting with a gardening expert. Once you know the nutrient requirements of your plants, you can choose a compound fertilizer that provides the correct blend of nutrients.
Compound fertilizers can be applied in various ways, including broadcasting, side-dressing, and foliar spraying. Broadcasting involves spreading the fertilizer over the soil surface and then working it into the soil. Side-dressing involves placing the fertilizer in a band beside the plants, while foliar spraying involves applying the fertilizer directly to the leaves of the plant.
The application rate of compound fertilizers will depend on the specific product being used and the nutrient requirements of the plants. It is important to follow the manufacturer’s instructions carefully and not to over-apply the fertilizer, as this can lead to nutrient imbalances and can harm the plants.
Precautions when using compound fertilizers
Store fertilizers properly: Compound fertilizers should be stored in a cool, dry, and secure place, away from children and pets.
Wear protective gear: When handling compound fertilizers, wear protective gear such as gloves, a dust mask, and safety glasses to prevent skin and eye irritation.
Do not over-apply: Over-applying compound fertilizers can lead to nutrient imbalances and can harm plants and the environment. Always follow the manufacturer’s instructions carefully.
Compound fertilizers are a valuable tool for farmers and gardeners who want to ensure that their plants have access to the essential nutrients they need for healthy growth and development. By understanding the different types of compound fertilizers, their benefits, and how to use them correctly, you can improve plant growth and yield while also reducing environmental harm. Whether you are growing fruits and vegetables or ornamental plants, compound fertilizers can help you achieve the healthy, vibrant plants you desire.
