is an organic-mineral fertilizer that focuses on three key ingredients. The choice of this fertilizer depends on the specific needs of the crop and the soil.

For traditionalists of NPK fertilizers

O-3+ is a complex organic-mineral fertilizer containing humic substances, nitrogen, phosphorus and potassium and trace elements. It is designed for foliar and soil feeding of various crops at all stages of growth.

Ensures high yield levels, improves the quality of cereals, oilseeds and leguminous crops, vegetables, ornamental and fruit crops and berries. Helps develop the growth of the plant root system and improves the utilization of nutrients from the soil.

Essential areas of O-3+ activity

Restoring soil fertility potential: O-3+ fertilizer helps restore or increase soil fertility by providing organic matter, macro- and micronutrients that promote healthy plant growth and activate soil microorganisms.

Increase seed germination and germination energy: O-3+ fertilizer can stimulate the seed germination process, increasing the number of germinated seeds and improving their germination strength and energy. This contributes to better and more uniform plant emergence.

Stimulating root formation in plants: O-3+ fertilizer promotes the development of the plant's root system, which is crucial for healthy growth, better uptake of water and nutrients from the soil.

Increasing immunity in plants: O-3+ fertilizer strengthens the immunity of plants, making them more resistant to threats and pests.

Mitigation effect on the use of pesticides: O-3+ fertilizer has a mitigating effect on the use of pesticides and alleviates possible side effects.

Promotes rapid rooting of cuttings and seedlings: O-3+ fertilizer accelerates rooting of cuttings, which is important for healthy and stable plant growth.

Activating plant growth and accelerating plant development: O-3+ fertilizer stimulates plant growth and accelerates plant development, leading to healthier and stronger plants.

Increasing the effectiveness of mineral fertilizers and pesticides: O-3+ fertilizer can improve the effectiveness of mineral fertilizers and pesticides used, allowing plants to better utilize available resources.

Gain higher yields of agricultural products: all the described characteristics of O-3+ fertilizer help plants achieve higher yields and better quality of agricultural products.

Extending the fruiting period and shortening the ripening period: O-3+ fertilizer affects plants in such a way that it extends the fruiting period and shortens the time needed for fruit mellowing.

Main characteristics of O-3+ fertilizer

  1. multicomponent with emphasis on 3 basic
    nutrients: nitrogen (N), phosphorus (P) and potassium (K)
  2. high efficiency in providing key
    nutrients to plants
  3. comprehensive, adapted to the general needs of most plants
