SOIL-SOILN Simulations of Water Drainage and Nitrate Nitrogen Transport from Soil Core Lysimeters

Abstract With a view to determining nitrogen sink processes, if any, in streams and the factors that govern these processes, nitrogen transport was studied in a 2 km-long, perennial, spring-fed stream during the summer months of 1973 and 1974. Concentrations of ammonium, nitrite and Kjeldahl nitrogen were small but those of nitrate nitrogen were unusually high. However, as the water moved downstream it progressively lost nitrate N. This loss represented 59.4% and 46.7% of the respective inputs during 1973 and 1974. The decrease in the concentration of nitrate N could neither be attributed to dilution nor to nitrogen immobilization during decomposition of organic matter nor to the uptake by aquatic macrophytes. Laboratory experiment showed that the stream sediments have significant, capacity for denitrification of nitrate in water overlying them, even when the water is thoroughly oxygenated. Although the role of riparian plants in the uptake of nitrogen has not been fully elucidated, it seems that denitrification in the stream sediment may act as an important permanent nitrogen sink.

Nitrogen Contamination

The progress of civilization as well as the growing up process of transformative environment adversely affect individual environmental elements in the soil. In recent years the increasing pollution of the atmosphere causes more and more interest in the science of the substances contained in it and merge back to the surface of the Earth. Of great importance for the environment have the substances contained in the water drainage, as in the form of dissolved very easily reach the individual environmental elements causing their contamination. Strong acidification most soils in Poland is the main cause of weak download main nutrients in soils, and low yields. Part of important plant micronutrients: iron, copper, zinc, manganese, cobalt/an acidic soils are more available In soils acidic phosphorus being introduced in mineral fertilisers is associated with aluminum and iron, in forms not available for plants. The low pH of the soil inhibits the oxidation of ammonium nitrogen (NH4+) to nitrate (NO3-), and at the same time, poorly developed root system is not able to efficiently download ion nitrate from the soil. The result is outside the range of the washing of nitrate nitrogen contamination of groundwater and is followed by the root system. The purpose of the work was to determine the pH of precipitation and atmospheric.
