O článku:
Nitrates belong to the major nutrient required for plant growth and they are generally very well soluble in water often used as fertilizers in agriculture. The higher values of nitrates concentration will occur in the case of large amounts use of fertilizer in intensive agriculture, pipe damage or damaged drainage near wells. The fertilization reduction could be one of this problem solution for health protection, environmental and economic reasons. In our study, the spectrophotometric determination of nitrates concentration in 5 times over-fertilized soil in lysimeters localized in the Eastern Slovakia Lowland showed nitrates leaching in the 40 cm layer of sandy soil, while in the silty-loam soil profile nitrates were not detected. The main goal of the experimental work was to show different nitrates leaching through two types of soil profile differing in hydraulic soil properties. Low retention capacity and high hydraulic conductivity of sandy soil (locality Poľany) were favourable for nitrate leaching in comparison with higher retention and conductivity of silty-loam soil (locality Vysoká nad Uhom) under relatively low precipitation events in the studied period from April 29th to May 28th 2019.
