Complex fertilizer ammophos contains two elements vital for plants - phosphorus and nitrogen. The components are water-soluble and are in a form easily accessible to plants. The effectiveness of the drug is associated with a high concentration of active substances and good physical characteristics. Ammophos is used as the main means for additional fertilizing during the growing season.
Description of ammophos
The fertilizer composition was developed to provide plants with a sufficient amount of phosphates in case of underconsumption or poor absorption from other fertilizers.The lack of easily digestible phosphorus is especially noticeable at the initial stage of development, during the period of intensive growth of the root system. Lack of phosphorus negatively affects the formation of reproductive organs.
The development of the entire plant is inhibited, the ripening of fruits is suspended, and as a result, the yield decreases. In addition, the lack or poor absorption of phosphorus slows down the positive effect of other, primarily nitrogen, fertilizers on plants. Therefore, for most crops, the required dose of phosphorus is first applied.
Attention! Ammophos is the best fertilizer for use in greenhouses and greenhouses.
Fertilizer composition
Ammophos - concentrated nitrogen-phosphorus fertilizer, in which the share of phosphorus is 52%, nitrogen - about 12%. Phosphorus should be considered as the main element, and nitrogen as an accompanying component. The drug also contains potassium, calcium, magnesium and sulfur.
Ammophos is significantly more effective than single-component fertilizers and mixtures, with the same nitrogen and phosphorus content. According to experts, 1 kg of ammophos can replace 2.5 kg of ordinary superphosphate and 0.35 kg of ammonium nitrate. In other words, the substance is almost three times more effective than a conventional, one-component fertilizer.
Ammophos is a complex fertilizer. It is obtained by neutralizing phosphoric acid with ammonia. The composition of ammophos is expressed by the chemical formula NH4H2PO4. Unlike superphosphate, it has a pronounced crystalline structure. It is a product that does not contain nitrates and chlorine. Let's dissolve in water.
Release form
The herbicide is produced in granular form under the brand “A” and in powder form under the brand “B”.Both brands of ammophos contain 44–52% phosphorus and 10–12% nitrogen. Shapes:
- Granulated ammophos grade “A” is recommended to be used locally before sowing, as a starter or row.
- Ammophos grade “B” is used as the main product and as a top dressing for continuous sowing crops. These are perennial grasses on forage lands, natural green lawns for park and sports purposes.
Ammophos is sold in retail stores in soft containers or plastic bags. The product is shipped in bulk to large agricultural enterprises.
Physical and mechanical characteristics
The drug has good product characteristics in the following parameters:
- The drug has a degree of hygroscopicity, in which the substance does not absorb moisture from the air during storage and transportation. This means that the fertilizer does not become damp, does not stick together, and does not lose flowability.
- The product dissolves in the aquatic environment, which significantly increases the possibilities of its use and methods of application to the soil. Fertilizer solutions are suitable for use in watering and drip irrigation.
- The granules are uniform in size and strength, and have the same shape. These qualities are especially important when applying fertilizer to the soil using a mechanized method, and allow the fertilizer to be distributed evenly over the area of the site.
- The preparation contains an optimal amount of moisture of about 1%, which ensures the strength of the granulometric composition and ensures the flowability of the product at all stages from loading to application to the soil.
The high concentration of active ingredients and the almost complete absence of ballast makes the use of ammophos very economically profitable.In the conditions of farms and agricultural enterprises, the costs of storage, transportation, and application of fertilizers to the soil are significantly reduced.
Important! Phosphorus does not move well in the soil. Bring in phosphate fertilizers should be as close as possible to the root system of plants.
Recommendations for use
The instructions for using ammophos recommend using the product for all climatic zones, applicable to both arid and fertile soils. Ammophos is equally effective in protected and open ground. Suitable for application under winter and spring-summer plantings, as a main fertilizer or additional feeding. When diluted, it can be used in drip irrigation systems. Phosphorus-nitrogen fertilizers are necessary for fruits and berries, vegetable crops, root crops, cereals, perennial herbs and flowers. As the main fertilizer, the following consumption rates per 1 square meter apply. m. area:
- When preparing the soil, apply up to 30 g for vegetables;
- for root vegetables this norm is 15–25 g;
- for fruit and berry bushes, apply at the rate of 15–30 g;
- Apply up to 15–20 g of ammophos under lawn grasses and flowers.
As a vegetative feeding, the norm is from 5–10 g for root crops, vegetables and fruit crops. When feeding flowers, berry bushes, and perennial herbs, use 4–5 g of the drug. Some correction to the standards is made by the extended action of fertilizers used previously.
Features of using ammophos
As the main fertilizer, ammophos is applied in the fall or early spring when digging the soil at the rate of 15–30 g per 1 m² of area. In a greenhouse or greenhouse, they consume 40–50 g per 1 m² of area.When growing seedlings, 1–2 g of the drug is added per 1 linear meter of planting, embedding it into the soil to a depth of 5–6 cm. Id the furrows with liquid fertilizer, diluting 20 g of ammophos in a bucket of water.
Fertilizing in autumn and early spring is carried out depending on the type of crop. Furrows are prepared along the perimeter of the root circle. The depressions are moistened and brought to a depth of 5–6 cm, mixing with soil. To quickly deliver nutrients to the roots of the plant, the granules are dissolved in normal volumes of water and used for root feeding.
It is convenient to use liquid fertilizer for automatic watering systems or drip irrigation. Initially, 1 kg of fertilizer is dissolved in a bucket of water. Allow time for the drug to dissolve and filter the mixture. The resulting solution is a highly concentrated aqueous extract. It should be diluted in a ratio of 1:50. The result should be 500 liters or 50 buckets of finished fertilizer. In a diluted state, the solution is used for simple watering from a watering can or for automatic drip irrigation systems.
Ammophos is a valuable nitrogen-phosphorus fertilizer with a high concentration of active, easily digestible substances. Proper use of the drug provides plants with a complete set of macro- and microelements.
