Plonagro Magnesium + Sulfur is an advanced organic-mineral fertiliser that supports the proper nutrition of plants with magnesium and sulfur and improves soil properties. HUMIACTIVE COMPLEX® provides over 200 kg humic acids in each ton of fertiliser, limiting the leaching and wasting of nutrients and allowing for more effective use of minerals, including nitrogen, by up to 50%. FASTMAG FORMULA® combines an easily absorbable form of magnesium with humic acids, while FASTCALC FORMULA® supports quick and safe optimization of soil pH. The product also improves the sorption properties of the soil and supports the development of the root system and the condition of plants.
We would like to inform you that the product Plonar Active Magnesium + Sulfur changes its name to Plonagro Magnesium + Sulfur. The change concerns the graphic design and trade name – it is a new level of professional support for your crops while maintaining the current, reliable effectiveness!
Discover the benefits
Plonagro Magnesium + Sulfur provides 4,5% MgO and 9% SO₃, supplementing fertilisation with two important nutrients. FASTMAG FORMULA® combines an easily absorbable form of magnesium with humic acids, which allows for the effective use of magnesium after dissolving the fertiliser in the soil. The humus complex also limits the loss of elements and supports better use of mineral fertilisers, including nitrogen fertilisers.
HUMIACTIVE COMPLEX® provides over 200 kg humic acids in each ton of fertiliser. Humic acids improve the structure of the soil, limit the leaching and wasting of nutrients and help keep them in the root zone. Plonagro Magnesium + Sulfur increases the soil’s sorption capacity by up to 10 times and supports better use of mineral fertilisers, including nitrogen fertilisers. The product also has a positive effect on the development of the root system and the condition of plants.
Product composition
Plonagro Magnesium + Sulfur is an organic-mineral fertiliser containing 4,5% magnesium (MgO), 9% sulfur (SO₃), 15% calcium (CaO) and 20% organic matter in dry mass. The formula combines minerals with a humus complex, supporting their effective use and limiting losses caused by leaching and retrogression.
HUMIACTIVE COMPLEX® provides over 200 kg humic acids in each ton of fertiliser. Humic acids improve the structure of the soil and limit the leaching and wasting of nutrients. The resulting humic chelates allow for more effective use of minerals, including nitrogen, by even 50%.
FASTCALC FORMULA® combines highly reactive calcium ions with humic acids, supporting the rapid and safe optimization of soil pH. FASTMAG FORMULA® uses an easily absorbable form of magnesium combined with humic acids, which allows full use of this ingredient after dissolving the fertiliser in the soil. Both technologies complement the action of the humus complex and the mineral composition of the product.
Plonagro Magnesium + Sulfur contains a minimum of 4,5% magnesium (MgO), 9% sulfur (SO₃) and 15% calcium (CaO). The formula is completed with 20% of organic matter in dry matter. The combination of minerals with a humus complex supports their use by plants and the properties and fertility of the soil.
Application method
Plonagro Magnesium + Sulfur is recommended to be used before sowing before planned cultivation, which allows the fertiliser to be moved with the top layer of soil to a depth of approximately 15 cm. The granules can be spread evenly on the field surface or used under seeding, directly under the plants. The fertiliser can also be used in reduced cultivation systems.

Plonagro Magnesium + Sulfur should be used before sowing before the planned cultivation, enabling the granulate to be moved with the top layer of soil to a depth of approximately 15 cm. The product can be spread evenly on the field surface or applied under seeding directly under the plants. The dose should be adjusted primarily to the soil’s abundance of magnesium and sulfur.
Plonagro Magnesium + Sulfur can also be used in simplified cultivation. The homogeneous form of granules allows for even application using standard fertilisation equipment. The product can be spread on the surface or used under seeding, directly under plants.
The fertiliser dose should be adjusted to the soil’s magnesium and sulfur content. Plonagro Magnesium + Sulfur is recommended to be used before sowing before planned cultivation.
| Soil content in Mg and S | Recommended dose |
| High | 100 kg/ha |
| Average | 200 kg/ha |
| Low | 300 kg/ha |
In perennial crops, the fertiliser dose can be increased, not exceeding 500 kg/ha. The fertiliser should be spread evenly on the field surface or used under seeding, directly under the plants. When applying pre-sowing, it is recommended to move the granules with the top layer of soil to a depth of approximately 15 cm.
Information
Plonagro Magnesium + Sulfur combines fertilisation with magnesium, sulfur and calcium with the action of a humus complex and organic substances. The product supports the effective use of nutrients, improvement of the sorption and water properties of the soil and the development of native positive bacterial microflora. Thanks to its granulated formula, it can be precisely used in various cultivation systems.
Plonagro Magnesium + Sulfur is available in bags 20 kg – a full pallet includes 36 pieces, and a half-pallet 12 pieces – and in Big-Bag packages weighing 500 kg. The available variants allow you to adjust the order size to the farm area and the planned fertiliser dose.

The term of application of magnesium fertiliser depends on the type of product and fertilisation technology. Plonagro Magnesium + Sulfur is recommended to be used before sowing before planned tillage, allowing the granulate to be moved with the top layer of soil to a depth of approximately 15 cm. The product can be spread on the surface or used under seeding directly under the plants, and the dose is adjusted to the soil’s magnesium and sulfur content.
The National Patronage Farm Program (OPGP) enables farmers to purchase Plonagro directly from the producer with a discount amounting to -50% price. The rules for joining the Agrizaz community are extremely clear: all you need to do is own a farm, make one minimum logistic purchase for your own use and hang up a patronage banner. The program does not contain hidden obligations or legal loopholes – if the technology does not meet your expectations, you are not obliged to continue shopping.
