Leaching of plant nutrients in soils part 2 loss of nitrogen as influenced by the form of fertilizer



Leaching of plant nutrients in soils part 2 loss of nitrogen as influenced by the form of fertilizer



Acta Agriculturae Scandinavica 25(1): 33-41



The leaching of NO3, NO2 and NH4 was studied in outdoor lysimeters fertilized at rates of 0 N, 1 N and 3 N with Ca(NO3)2, Nitro-Chalk (NH4-N:NO3-N = 1:1), (NH4)2SO4 and urea with rape as a crop. A treatment with (NH4)2SO4 + N-Serve was also included. The soil was the upper part of the subsoil of an illitic medium clay. Two waterings after planting to simulate a heavy rain before the development of the shoots, led to large losses of N in the lysimeters with Ca(NO3)2. During the growing season the leaching was high in the 3 N treatments with NO3 fertilizers but low in the 1 N treatment and very low in the lysimeters with urea and (NH4)2SO4. The total losses of N until the harvest of the 1 N lysimeters did not exceed 0.5% for urea and were slightly above 1% for (NH4)2SO4. As a result of promoted nitrification, the leaching of NO3 after harvest increased strongly in the NH4- and urea-fertilized lysimeters after the experiment temperature was raised to 23-25.degree. C (indoors). During the growing season the NO3 concentration was very high in the leachates from the NO3-fertilized 3 N lysimeters and moderate from the 1 N lysimeters. In all treatments the leaching of NH4 was low or very low. The content of NO3 of the crop increased with the fertilizer rate, more for NO3 fertilizers than for NH4 fertilizers. Application of (NH4)2SO4 and urea increased the exchangeable and fixed NH4 of the soil. Balance calculations show that the soil after heavy N fertilization builds up a reserve of N compounds, part of which is found in root residues, and which is only slowly mobilized and lost by leaching.
