Influence of nitrogen content in the soil solution on potential nitrogen mineralization of organic residues

Abstract: Application of organic residues to soil may supply nutrients to plant, namely, nitrogen (N). But, generally, organic residues contain mostly organic N that has to be mineralized prior to plant uptake. This process depends on several parameters such as the carbon to nitrogen ratio of the residues or the soil moisture. The aim of the present work was to assess the effect of the ammonium (NH 4 þ ) and organic N contents of the soil solution on potential N mineralization (PNM) of organic residues applied to soil. … Show more

“…It is likely that soil nutrients limit the accumulation of N to a certain degree (Guo and Li, 2012;Sammul et al, 2012). A possible explanation for the high ammonium-N content and soil EC on the shady slope is that ammonium-N remains stable at high moisture levels (Davenport et al, 2012;Fangueiro et al, 2012) because it is easily formed and can persist in the soil in a solid phase. Although soil moisture is important for limiting the movement of ammonia, it does not ultimately determine whether the NH 4 + will remain in the soil.…”

“…Es así, como Fangueiro et al (2012) reportaron que una pequeña cantidad de N orgánico y amonio (N-NH 4 + ) en la solución del suelo, mejoraba el potencial de mineralización neta de N de los residuos orgáni-cos, mientras que grandes cantidades, disminuyó el potencial de mineralización neta de N, y podría conducir a la inmovilización del mismo.…”

“…(2013) encontraron una relación negativa entre el nitrógeno disponible en el suelo y el nitrógeno mineralizado durante el ciclo del cultivo del melón. Otros autores, también han informado del efecto de la cantidad de nitrógeno en la solución del suelo, sobre la velocidad de mineralización de residuos orgánicos (Fangueiro et al, 2012) como consecuencia de un descenso de la actividad microbiana (Fog, 1988).…”
