This work has as objective to evaluate the leaching of nitrogen regarding the soil particle-size. The experimental adopted was entirely randomized with arrangement factorial 5 x 2, with five soils (three Ultisol, one alfisol and one oxisol) with different particle-size (37.5; 132.5; 315.0; 491.2 e 546.0 g kg-1 of clay), collected in the region north of the Paraná State, and two nitrogen sources (potassium nitrate and ammonium sulphate) with four repetitions. One treatment witness without nitrogen was included to allow additional statistical tests. The soil were packed in columns of PVC with 25 cm of height and 4 cm of diameter, and posteriorly irrigated until the field capacity. The sources of nitrogen were applied in the quantity equivalent to 65 kg ha-1 of N and afterwards, was applied 150 cm3 of distilled water, corresponding to a precipitation of 180 mm. The use of KNO3, potassium nitrate resulted in higher N losses by leaching, compared to ammonium sulfate, presenting a negative correlation with clay content. 2010 artículo científico 1519-1125 https://www.redalyc.org/articulo.oa?id=99515218012 en http://www.redalyc.org/revista.oa?id=995 Scientia Agraria application/pdf Universidade Federal do Paraná Scientia Agraria (Brasil) Num.2 Vol.11 |
