Plonagro – Comprehensive Soil Fertilisation and Structure Improvement

Plonagro is an innovative organic-mineral fertiliser that combines a humus complex with minerals and organic substances. It contains over 200 kg humic acids in each ton of fertiliser, increases the sorption capacity of the soil up to 12 times and significantly increases its water capacity. The humic complex limits the loss of nutrients caused by leaching and retrogression, and humic chelates allow for more effective use of minerals, including nitrogen, by up to 50%. Plonagro improves the soil structure, activates the development of native positive bacterial microflora and supports the restoration of the natural fertility of the site.

Discover the benefits

A revolution in soil fertilisation and water retention

Plonagro supports the restoration of natural soil fertility by increasing the humus content, improving its structure and maintaining nutrients and water in the root zone of plants. The humus complex helps limit losses of elements caused by leaching and backwatering, while the increased water capacity of the soil helps limit the effects of periodic water shortages. The product also activates the development of native positive bacterial microflora and has a beneficial effect on the condition of plants.

Humus complex, minerals and lasting soil fertility

Plonagro is an organic-mineral granulate containing over 200 kg humic acids in each ton of fertiliser, as well as phosphorus, potassium and calcium. The humus complex supports the formation of humus, improvement of soil structure and retention of nutrients in the root zone. The product also contains 35% organic matter in dry matter and activates the development of native positive bacterial microflora, supporting the natural fertility of the soil.

Water retention and more efficient use of nutrients

Plonagro significantly increases the water capacity of the soil, helping to reduce losses caused by periodic water shortages. At the same time, it increases the sorption capacity of the soil up to 12 times, thus increasing the availability of nutrients for plants. The humic complex limits the leaching and depletion of elements, and humic chelates allow for more effective use of minerals, including nitrogen, by even 50%.

Product composition

Rich organic-mineral composition for maximum efficiency

Plonagro combines a humus complex with phosphorus, potassium, calcium and a high content of organic matter. The ingredients contained in the product support the proper development of plants, while the humus complex helps to increase their utilization and reduce losses caused by leaching and deterioration. The combination of the organic and mineral parts also supports the improvement of the structure, sorption properties and fertility of the soil.

Over 200 kg humic acids in each ton

Plonagro combines a humus complex with phosphorus, potassium, calcium and a high content of organic matter. The ingredients contained in the product support the proper development of plants, while the humus complex helps to increase their utilization and reduce losses caused by leaching and deterioration. The combination of the organic and mineral parts also supports the improvement of the structure, sorption properties and fertility of the soil.

Minerals: phosphorus, potassium and calcium

Plonagro contains a minimum of 3,5% phosphorus (P₂O₅), 6,5% potassium (K₂O) and 9,0% calcium (CaO). Minerals interact with the humus complex, which helps maintain the elements in the root zone and limit their losses caused by leaching and deterioration.

Organic matter and soil microflora activators

Plonagro contains 35% organic matter in dry matter and components supporting the development of native positive bacterial microflora. The combination of organic substance with a humus complex and minerals supports the reconstruction of the natural fertility of the soil, improving its structure and maintaining water and nutrients in the root zone.

Application method

How and when to use Plonagro for best results?

Plonagro is recommended to be used before sowing, before planned cultivation, allowing 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 product can also be used in simplified and organic farming. The dose should be adjusted to the type of crop and the selected annual or 5-year fertilisation cycle.

Application date: before sowing and before planned cultivation

Plonagro is recommended to be used before sowing, before planned cultivation, allowing the fertiliser to be moved with the top layer of soil to a depth of approximately 15 cm. Granules should be spread evenly on the field surface or used under seeding, directly under the plants. This method of application allows you to use the properties of the humus complex and minerals directly in the development zone of the root system.

Use in simplified and organic farming

Plonagro can also be used in simplified cultivation systems and in organic farming. The granules can be evenly distributed on the field surface or used as undersowing directly under the plants. The flexible form of granules allows application using standard disc spreaders and fertiliser spreaders.

Recommended dosage Plonagro in the annual and 5-year cycle

The Plonagro dose should be adjusted to the type of crop and the selected fertilisation cycle. In the annual cycle, the fertiliser is applied once a year before sowing, while in the 5-year cycle, once every 5 years before sowing.

Cultivation Annual cycle 5-year cycle
Cereals 60 kg/ha 300 kg/ha
Root crops 100 kg/ha 500 kg/ha
Corn 80 kg/ha 400 kg/ha
Vegetables 80 kg/ha 400 kg/ha
Strawberry 80 kg/ha 400 kg/ha
Currant / Raspberry 100 kg/ha 500 kg/ha
Fruit trees 100 kg/ha 500 kg/ha

Plonagro is recommended to be used before sowing before planned tillage, allowing the fertiliser to be transferred with the top layer of soil to a depth of approximately 15 cm. The fertiliser can be spread evenly on the field surface or used under seeding, directly under the plants.

Frequently Asked Questions (FAQ)

When to water with humic acids?

In the case of Plonagro humic acids are supplied in the form of granulated organic-mineral fertiliser, therefore the product is not applied by watering. Plonagro is recommended to be applied before sowing before planned cultivation, spreading the granules evenly on the field surface or using it as subsowing directly under the plants. When applying surface fertiliser, the fertiliser should be moved with the top layer of soil to a depth of approximately 15 cm.

The effectiveness of fertilisers containing humic acids depends, among other things, on the correctly selected dose, method of application and soil conditions. In the case of Plonagro, the dose is adjusted to the type of crop and the selected fertilisation cycle – annual or 5-year. It is best to apply the fertiliser before sowing, before the planned cultivation, so that it is transferred with the top layer of soil.

Humic acids support the improvement of the structure and sorption properties of the soil, help limit the leaching and depletion of nutrients and keep them in the root zone. In Plonagro the humus complex allows you to increase the sorption capacity of the soil up to 12 times, significantly increases its water capacity and supports more effective use of minerals by plants.

Plonagro contains over 200 kg humic acids in each ton of fertiliser, therefore the amount delivered per hectare depends on the dose intended for a specific crop. For example, the annual dose of 60 kg/ha for cereals provides more than 12 kg of humic acids per hectare, the dose of 80 kg/ha provides more than 16 kg, and the dose of 100 kg/ha provides more than 20 kg. In the 5-year cycle, appropriately higher single doses are used, adapted to the type of crop.

Plonagro is a granulated organic-mineral fertiliser which, in addition to over 200 kg humic acids in each ton, also provides phosphorus, potassium and calcium as well as 35% organic matter in dry matter. The granulated form allows for even sowing using standard disc spreaders, as well as under-sowing application directly under the plants. Unlike liquid humus preparations, Plonagro combines the action of a humus complex with mineral fertilisation in one granulated formula.
