| Description
| - 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 kgN . ha--1 as UREA stabil and unfertilised control. Each treatment was repeated 4 times. The focus of the experiment was to monitor the effect of two different fertilisers and different N-doses on the yields of potato tubers and content of nitrogen (N) and cadmium (Cd) in tubers and tops (stems + leaves). In 2011 the contents of nitrogen in the tubers fluctuated between 14.3 and 15.6 g . kg--1 d.m. and in the tops between 29.7 and 40.9 g . kg--1 d.m. The contents of cadmium in tubers ranged between 0.14 and 0.17 mg . kg--1 d.m. and in tops between 0.50 and 0.72 mg . kg--1 d.m. In 2011 the tuber yields fluctuated irregularly, i.e. between 17.0 and 32.9 Mg . ha--1. In 2012 the nitrogen contents in tubers ranged between 16.0 and 17.3 g . kg--1 d.m. and in the tops between 23.9 and 36.9 g . kg--1 d.m.
