NPK Powder
Woprofert NPK Soluble Powders
We are able to offer you several standard formulations (as mentioned below), also custom-made formulas are possible (min, 10 mt net). It can be packed in standard neutral or simple labeled WPP/PE-bags of 25 kg net, or in a pre-printed PE or WPP/PE laminated- bag, min. quantity of 10,000 bags.
The Woprofert NPK soluble powder is produced from premium-quality raw materials, without residues.
Guaranteed:
• a low chlorine content (< 0.5%) preventing the risk of salinity;
• homogeneity, without separation of phase;
• free-flow and anti-caking, from the factory gate;
• humidity of less then 0.2% at packaging
• anti-clogging, thanks to a pH-value from 3.3 to 4.5 inclusive, at a concentration of between 1 and 3 g/l inclusive;
• EDTA-chelated trace-elements, other than boron, preventing leaching and guaranteeing perfect absorption.
Woprofert High Nitrogen:
• a family of products with high nitrogen content and an NPK ratio of 2-1-1 or 3-1-1.
• improves the vegetative development of fast growing plants. It is recommended that it is applied from the beginning of the vegetative growth until the end of the flowering period. It is well adapted for sandy soils and those lacking in organic material. It is also recommended where plants show lack of vigor.
• We offer the following Woprofert High Nitrogen formulas corresponding to various types of culture, soil and irrigation system:
The three nitrogen sources ensure progressive availability and avoid leaching. Phosphorus derives from the M.A.P. and potassium from potassium nitrate and/or potassium sulfate. Legal tolerances as per EC-regulations.
Woprofert High Phosphorus:
• a family of products with a high phosphorus content and an NPK ratio of 1-2-1, 1-3-0.7, 1-3-2 or 1-3.8-2.5.
• well suited to soils lacking or poor in phosphorus. On well balanced oil, it is generally used just after planting out or seeding. It is also recommended that it be used just before the flowering of crops with a high charge (i.e. tomatoes).
• Phosphorus improves the rooting phase, the flowering induction and the fruit production at the end of the vegetative phase. Crops requiring phosphorus are potato, onion, strawberry, Brussels sprouts, spinach, tomato and flowers.
• We offer the following Woprofert High Phosphorus formulas corresponding to various types of culture, soil and irrigation system: 
The three nitrogen sources ensure progressive availability and avoid leaching. Phosphorus derives from the M.A.P. and potassium from potassium nitrate and/or potassium sulfate. Legal tolerances as per EC-regulations.
Woprofert High Potassium :
• a family of products with NPK ratios of 1-1-2, 1-1-3, 1.5-1-3 of 1-2-5.
• Well adapted for soils lacking in potassium and improves the fruit and vegetable ripening phase (from end of development until harvest).
• Potassium increases resistance against temperature stress. It is a key element for sugar and starch synthesis, so contributes to the quality of the harvest product.
• Particularly recommended for crops that require potassium (potato, onion, cauliflower, tomato, begonia, etc.).
• We offer the following Woprofert High Potassium formulas corresponding to various types of culture, soil and irrigation system:
The three nitrogen sources ensure progressive availability and avoid leaching. Phosphorus derives from the M.A.P. and potassium from potassium nitrate and/or potassium sulfate. Legal tolerances as per EC-regulations.
Woprofert Balance:
• a family of products with an NPK ratio of 1-1-1.
• Suited for well-balanced soils. Requirements of plants in the vegetative phase and/or fruit development are met and it guarantees you the best results.
• We offer the following Woprofert Balance formulas corresponding to various types of culture, soil and irrigation system:
The three nitrogen sources ensure progressive availability and avoid leaching. Phosphorus derives from the M.A.P. and potassium from potassium nitrate and/or potassium sulfate. Legal tolerances as per EC-regulations.
Woprofert High Potassium / Low Phosphorus:
• a family of products with a low phosphorus content and NPK ratios of 3-1-6, 4-1-6 or 4-1-11.
• Well suited to soils with a high phosphorus content, during the phase of vegetative growth.
• For well-balanced soils, apply it after flowering or at the beginning of the fruit development. It improves fruit/vegetable ripening. A supplement of magnesium is recommended at this stage.
• We offer the following Woprofert High Potassium / Low Phosphorus formulas corresponding to various types of culture, soil and irrigation system:
The three nitrogen sources ensure progressive availability and avoid leaching. Phosphorus derives from the M.A.P. and potassium from potassium nitrate and/or potassium sulfate. Legal tolerances as per EC-regulations.
Woprofert NPK soluble powders can be used in all types of fertigation systems (drip/b/drip, micro-jet, capillary, sprinkler).
For fertigations systems: 1 to 3 g/lt. of irrigation water
For foliar treatment: a 0.5% solution, either 1 kg per 200 lt. of 5 kg per 1000 lt.
The above recommendations should be adapted according to differences in climate, soil, temperature, varieties, yields and irrigation systems. In addition, the numbers of applications and the quantity per ha as well as the interval times may vary depending on the formulations.
