Effect of urea and urea with urease inhibitor on yields and nitrogen and cadmium content in potatoes

Popis výsledku v původním jazyce

Worldwide the urea fertilisers are the fastest growing and most commonly used source of nitrogen in agriculture. The benefits of using urea as a fertiliser are due to its high nitrogen content (approximately 46 % nitrogen), non polarity, high solubility,and low costs for manufacture, storage, and transport. Among the various available mitigation tools, urease inhibitors like NBPT (N-(n-butyl) thiophosphoric triamide) have the highest potential to improve the efficiency of urea by reducing N losses, mainly via ammonia volatilization. In 2011 and 2012 a small-plot experiment was established with the potato Karin variety. The experimental locality was Zabcice, ca 30 km south of Brno, a maize-growing region. Prior to planting both mineral fertilisers (urea and urea with urease inhibitor NBPT -- UREA stabil) were applied to the soil surface. During planting these fertilisers were incorporated into the soil. The experiment involved 7 treatments: 54, 72, 90 kgN . ha--1 as urea, 54, 72, 90 kg
