Abstract
In the article are presented the investigation results, which shows the effectiveness of urea with urease inhibitor – nBPT in potato growing agroecosystems. The advantages of the new fertilizer are the yield increase, and quality improvement. Urea with nBPT lead to formation bigger tuber size what is one of the most important characteristic for marketable potato. Fertilizer was tested in experimental fields and in real farm conditions.
Highlights
Nitrogen is one of the most essential elements in plant nutrition
The application of different forms of nitrogen fertilizers did not affect the duration of the phenological phases of potato development, in all the experiments the vegetation period was 90 days from the germination period
It should be noted that the phase of flowering is characterized by decrease of nitrate nitrogen content in the treatment with application of ammonium nitrate
Summary
Nitrogen is one of the most essential elements in plant nutrition. Fertilities are the main sources of it. The most common are urea and ammonium nitrate Nitrogen assimilation of this element by plant root system occurs in the form of nitrate ion or ammonium ion [1]. Nitrogen losses in various forms – in gaseous forms (ammonia, nitrogen oxides) or as a result of leaching processes (nitrates) – have a negative impact on the environment, polluting air and water resources. All this processes leads to the deterioration of plants nutrition, and to environmental [2,3]
