Technical specification
Granulated tertiary complex fertilizer, containing 14% nitrogen, 28% phosphorus, 14% potassium, and 5.5% sulfur. It has a balanced nitrogen-to-phosphorus ratio of 1:2, making it suitable for all agricultural crops for base fertilization.
NPK fertilizers are complex highly efficient combined fertilizers with contents of the main macro-nutritional elements nitrogen, phosphorus and potassium. Advantage of the combined fertilizers is the contents of micro-nutritional elements and there are contents of sulphur in some of them. The fact that all the needed nutritional elements needed by the plant in the initial phases of its development are collected in one granule makes the NPK fertilizers very productive.
Except for stock fertilization they may also be used during vegetation for provision of the crops with nutritional substances in the critical phases of their development. The forms in which the nutritional elements are placed in the NPK fertilizers do not exert any impact over the acidity of the soils. The potassium form is presented as potassium chloride.
Due to their balanced form and the comparatively low contents of active substance the NPK fertilizers are very suitable for correcting fertilization. Fertilization during vegetation with NPK predisposes to bigger percentage of assimilation by the plants than if other one- and two-components “heavy” fertilizers are used. NP is nitrogen-phosphorus fertilizer, created for feeding soils which are provided with potassium in contents. It is suitable for fertilization of almost all the crops both at pre-sewing preparation and for correcting fertilization. NP has comparatively low contents of easy to assimilate in form nutritional elements which makes it the good solution for each farm.
The balanced contents of nutritional elements contribute to the full satisfaction of the needs of the plants of macro-nutritional substances.
The contents of more than one element in the fertilizer also contribute to the better assimilation of the nutritional elements by the roots of the plants. In the presence of phosphorus the nitrogen is assimilated in greater degree by the plants and the availability of more than one nutritional element in usable form contributes to the development of the plant organism of full value.
The ratio of the elements and the easily usable form, which they are in the NPK fertilizers in, makes them suitable for satisfying the needs of the plants in each stage of their vegetative development.
The selection of the specific formulations depends on the conditions and the kind of the grown up crops. The use of NP and NPK fertilizers guarantees maximal efficiency of the input means and provides balanced supply of nutritional substances of full value.
⊳ NP and NPK fertilizers are stored in covered, cold and dry warehouse premises.
⊳ Heating and mixing with water are not desirable.
It is transported packed or in bulk. They are offered in packages of polyethylene and polypropylene, in packages of:
— 50 kg
— 500 kg
Advantages
Applied in an appropriate programme for balanced fertilization with a view to the requirements of the specific crop, the type of soil and the microclimate of the area, the complex fertilizers have the following advantages:
- Balanced Nutrient Supply: The high phosphorus content (28%) is particularly beneficial for flowering and fruiting plants, making this fertilizer ideal for crops that require robust root systems and flowering, such as vegetables and fruit-bearing plants.
- Enhanced Growth: The combination of nitrogen and potassium promotes vigorous growth and improves the plant’s ability to withstand stress, such as drought or disease.
- Sulfur Benefits: The inclusion of sulfur aids in the synthesis of amino acids and proteins, which are vital for plant metabolism and growth. This is particularly beneficial in soils that may be deficient in sulfur.
- Improved Soil Health: Regular application can improve soil structure and microbial activity, leading to better nutrient availability and uptake by plants.
- Versatility: This formulation can be used across various crops, including vegetables, fruits, and ornamental plants, making it a versatile choice for farmers and gardeners.
