Sažetak
Nitrogen is a vital nutrient that helps plants and crops to grow, but high concentrations are harmful to people and nature. Generally, farming remains responsible for over 50% of the total nitrogen discharge into surface waters. The 1991 Nitrates Directive is one of the earliest pieces of EU legislation aimed at controlling pollution and improving water quality. Determining potato N needs and predicting the fertilization rate for the duration of the growing season cannot be based only on soil tests. Many researchers have found SPAD (potato - Westcott et al., 1991, corn - Wood et al., 1992) and Cardy-ion meter readings (vegetable crops - Hochmuth, 1994) as reliable indicators of plant N status during the growing season. The objective of this paper is to estimate effectiveness of proposed tools in determining plant N status of the autochthonous potato variety Poluranka.
