Wap Mag with microelements contains 28% of calcium (CaO), in the sulfate and carbonate form, 16% of magnesium (MgO) in the sulfate and in addition the micro-elements: 0,1% of boron (B), 0,1% of copper (Cu), 0,012% of molybdenum (Mo) and 0,1% of zinc (Zn). The varied solubility of the forms of the macronutients present in the fertilizer is conducive to the systematic release of the components  from the granule throughout the period of plant vegetation.


  • Calcium - ensures the good rooting of the plant, favorable conditions for absorbing other nutrients, better health of the crops. The carbonate form of calcium additionally locally deacidifies the soil.
  • Magnesium -provides the effective absorbtion and processing of the nitrogen into the yield, high sugar content in the roots (with a simultaneous decrease of undesirable melassogenic compounds), high fat content in the seeds of legumes and oilseeds, better health of the cultivated plants.
  • Boron - participates in the carbohydrate and protein metabolism, chlorophyll synthesis and the assimilation of CO2 and the development of the meristem and the apical tip of stems and roots.
  • Zinc - participates in energy metabolism, synthesis of vitamins C, B, PP and chlorophyll, activates the growth regulators.
  • Copper - affects the development and anatomical structure of many tissues and the development of root nodules of papilionaceous plants, increases the resistance to fungal diseases.
  • Molybdenum - participates in the metabolism of nitrogen and phosphorus, facilitates the absorption of iron, is essential in the process of nitrogen fixation by Rhizobia.



The Wap Mag with microelements fertilizer is designed for use on mineral and organic soils with a very acidic, acidic and neutral pH in all agricultural crops on arable land and permanent grassland. Due to the high magnesium content, it should be primarily used on soils with low and very low magnesium content.

This fertilizer contains calcium, magnesium and micronutrients B, Cu, Zn, Mo, and therefore is also recommended for use in crops of vegetables, fruit plants and ornamental plants, especially in acidic and slightly acidic soils. In orchards, fertilizer is particularly suitable for use in the cultivation of apple varieties susceptible to calcium deficiency and bitter rot.

Principles of application

For winter crops on arable land, fertilizer should be used for medium plowing. In the case of spring plants, or planting for winter or spring plowing. In other cases it is advisable to mix the fertilizer with soil to a depth of 15 cm.
In grassland, the fertilizer should be applied in accordance with the principles of soil fertilization in the spring before or at the beginning of vegetation and after swaths or pasturage. Fertilizer should be spread evenly over the entire surface of the field in such a way as to prevent fertilization of fields and crops not intended for this purpose. Do not use higher doses than recommended.

In agriculture, it is recommended to use this fertilizer for plants which are forecrops, as well as for plants with very high or high sensitivity to acidic soil (wheat, barley, beets, corn). The maximum effect is achieved in the second year after application. The best time to use "Wap Mag with microelements" is late summer, when the forecrops are cleaned up, covering it with soil during plowing or sowing. For growing vegetables, fruit plants and ornamental plants, it is particularly recommended in acidic and slightly acidic soils. The fertilizer can also be used in spring, summer and autumn, provided that a period of 3-4 weeks is available for carrying out cultivation. Furthermore, fertilizing orchards and berry plantations involves applying the fertilizer during the fruiting period. After sowing, the fertilizer should be mixed in with soil to a depth of 15-30 cm with a plow, cultivator or harrow.



Depending on the crop and magnesium availability in the soil, the fertilizer is used in agricultural crops for arable land and permanent grasslands in doses of 20 to 60 kg MgO/ha, which makes 130-350 kg of fertilizer per hectare. The fertilizer can be used alone or in a mixture with other granulated fertilizers.

For vegetables in field crops, it is recommended to use the fertilizer in the following doses:

Cultivated plants Dosing (kg/ha)
cauliflower, asparagus, green beans, cabbage (red, Brussels sprouts, early and late head cabbage, Chinese and Italian), pumpkin, sweet corn, rhubarb 130-350
kale, broccoli, carrots, celery (celery and celeriac), endive chicory, peas 100-250
leeks, kohlrabi (early and late), beetroot, radish, onion, tomato, cucumber, parsley, scorzonera, horseradish, chicory 70-180
Lettuce, radish, spinach (early and late) 50-100

For fertilizing orchards and berry plantations, it is recommended to use the fertilizer in the following doses:

Cultivated plants Dosing  (kg/ha)
Young orchards (1-3 years) all species 10-30
Fruiting orchards (from 4 years) all species 50-100
Currant and gooseberry plantations 100-200
Raspberry, strawberry plantations (first year of cultivation) 70-140
Strawberry plantations (subsequent years) 50-100

To fertilize ornamental plants grown in the field, we recommend using fertilizer in the following doses:

Cultivated plants Dosing (kg/ha)
Chrysanthemum, peony, iris, tulip, sunflower, pansy, consolida, ageratum, dahlia, snapdragon, celosia, zinnia, pink, stock, gladiolus 100-250
Begonia, calendula, purslane, aster, lobelia, petunia, lily, marigold, sage, daffodil, daisy, thyme 70-180
Amaranth, matthiola, nasturtium, fern, geranium, bergenia 50-120
Water pepper 50-100

These doses depend on the pH (pH in 1 M KCl), and the mechanical composition of the soil, as well as the plant's need for fertilization.
