AMOFOSKA NPK 5-10-25+ 0,1B


AMOFOSKA NPK 5-10-25 +0,1B is a fertilizer designed for intensive cultivation of winter and spring oilseed rape, mustard, brassica crops, legumes, and small-seeded legumes grown in pure sowing.

It is characterized by a high content of potassium, sulphur and boron. At a properly selected ratio it provides a high yield of proper quality of crops. Sulphur in the fertilizer, in a form that is readily-available to plants, stimulates the uptake and correct use of nitrogen, potassium increases the winter hardiness of oilseed rape, and the addition of boron – a micronutrient responsible for cell division - ensures proper flowering and tying of pods. This fertilizer can also be used for vegetables that require a good supply of potassium and sulphur, all brassica vegetables, carrots, celery, spinach, cucumbers and lettuce.

PROPERTIES

AMOFOSKA NPK 5-10-25+0,1B is a compound granular NPK fertilizer of the following nutrient content. The high quality of the granules (i.e. uniform size of seeds with a diameter of 2,0-5,5 mm) facilitates uniform sowing.
Macronutrients:

  • 5% N ammonium nitrogen (total),
  • 10% P2O5 phosphorus pentoxide soluble in mineral acids, including at least: 5% P2O5 phosphorus pentoxide soluble in neutral ammonium citrate, at least 2.5% P2O5 water-soluble phosphorus pentoxide,
  • 25% K2O water-soluble potassium oxide,
  • 5% CaO calcium (total),
  • 14% SO3 sulphur trioxide in the form of water-soluble sulphates,
  • 0,10% B water-soluble boron.

Micronutrients(Co, Cu, Fe, Mn, Mo, Zn) derived from natural phosphate rock are a valuable addition fertilizer, improving the bioavailability of other ingredients.

This fertilizer is neutral, thus it does not make soil acid and does not create the need for additional liming. Its components, i.e. sulphur and boron in the form that is easily-assimilable for plants, support and regulate their proper development. In addition, sulphur stimulating nitrogen uptake is a valuable nutrient for sulphur-loving and high-protein plants.

Under normal conditions this fertilizer does not contain harmful levels of heavy metals such as arsenic, cadmium, lead or mercury, so it is safe for the environment.

APPLICATION RULES

AMOFOSKA NPK+B 5-10-25+0,1 is a typical pre-sowing fertilizer which, after sowing on the ploughed land, needs to be mixed with soil.

Seed sowing can be done after 7-10 days from dispersal because the ammonium form of nitrogen and boron compounds should first be absorbed to prevent damaging germ seed by these components. This fertilizer should be dispersed on green crops in early spring.

It is suitable for all soils, irrespective of their compactness and degree of acidity; it is particularly suitable for use on soil with a low content of potassium and boron.

DOSES

The main plant nutrient contained in fertilizer AMOFOSKA NPK+B 5-10-25+0.1 is potassium, so the size of the doses must be determined according to the potassium needs of fertilized plants and by the abundance of potassium in the soil. Boron contained in the fertilizer determines the plant species to be fertilized with this micronutrient:

Fertilized plants Dose *
Winter rape 250 - 450
Spring rape 200 - 350
Sugar beet (on manure) 300 - 550
Fodder beet (on manure) 400 - 650
Red beet (on manure) 200 - 450
Early-season varieties of potatoes (on manure) 200 - 350
Late-season varieties of potatoes (on manure) 250 - 450
Legumes for seeds 200 - 400
Clover and alfalfa in pure sowing (green forage) 250 - 400
Mustard (white, black, brown) 200 - 300
Crops 200 - 450
Meadows 200 - 350
Pasture 150 - 300

* The doses given in the table are indicative and should be adjusted depending on the expected yield.

Nitrogen in the fertilizer is sufficient only for the first period of plant growth, then this component needs to be supplemented by stock use of nitrogen fertilizers (preferably urea or ammonium nitrate 'Puławy') according to the needs of the cultivated crops. When fertilizing meadows and pastures, single doses of fertilizer should not exceed 300 kg/ha, and higher doses of fertilizer should be divided into two parts. Boron contained in the fertilizer promotes an increased presence of legumes in sward. In the cultivation of sugar beet or potato without spreading manure, the given doses of fertilizer are recommended to be increased by 100 kg/ha.
