The essence of environmentally friendly nutrient management is to apply fertilizers and yield increasing materials in a timely manner and in such a way that the plants can utilize the nutrients in the best possible way, thus the nutrient losses are as low as possible.

In order to ensure the harmony of production and environmental aspects, it is essential to plan the economically available crop in the given production area taking into account the ecological conditions and to manage the nutrient demand of the soil and the nutrient requirements of the planned crop. Planning a nutrient management is a complex, multi-tasking task, so it is advisable to contact our colleagues specialized in nutrient management.

Soil nutrient management is determined by three factors:

Nutrient capital, which is the sum of the amounts of nutrients or one nutrient that is important to plants, varies from soil to soil. Nutrient capital can increase through bioaccumulation, application, or fertilization, and can be reduced by weathering, leaching, erosion, and by nutrients transported by the crops produced. The nutrient content that can be taken up by the plant is part of the nutrient capital. Soil nutrient supply capacity, which determines how long the uptake of nutrient content is ensured for crop production without loss of yield.

Professional nutrient replacement can be beneficial in terms of its environmental impact because:

Fertilization increases green plant production. This means making better use of natural conditions, which help to rationally manage the energy and material resources of the environment. The greater assimilation surface created by the greater green mass reduces the carbon dioxide content of the atmosphere and increases its oxygen content. As a result of industrialization, transport and urbanization, air pollution increases and vegetation plays a significant role in keeping the air clean. Water utilization studies have revealed that the better the plant's nutrient supply, the less water it uses to produce a unit of dry matter.

The environmental impact of excessive or possibly inappropriate fertilization, particularly in the long term, may be due to:

Nitrogen, leached from soil and migrating to groundwater, is harmful to the environment, increasing the nitrate content of wells and drinking water; Water erosion results in increased eutrophication of the phosphorus and nitrogen content of the soil into the surface waters; High-dose fertilization by increasing calcium leaching can lead to soil acidification in the long run, while also reducing the duration of soil remediation in limed soils.

Fertilization may also have adverse effects on the content and quality of the plants:

The high or one-sided application of fertilizers adversely affects the soil micro-nutrient content and its uptake. In the fertilized areas, weeds also develop better, which results in more intensive and frequent mechanical planting and weeding. chemical plant protection.
