Efecto de la fertilización fosfatada sobre la composición química de Lotus tenuis y Trifolium repens

Abstract: Una manera de aumentar el rendimiento y calidad de forraje de las pasturas nativas es a través de la inclusión de leguminosas en el tapiz. Para un establecimiento apropiado de las mismas es necesario contar con una disponibilidad adecuada de fósforo (P) en el suelo. Dados los niveles deficientes de este nutriente en muchos suelos, es necesario su aporte a través de la fertilización. El objetivo del presente estudio fue evaluar el efecto del P aplicado a la siembra en varias dosis sobre el contenido de P y nitr… Show more

“…Marandu and by Xu et al (2016), who reported that different mixtures and levels of water and fertilizer supply, mainly N and P combined, affect the N and P concentrations in different organs of B. ischaemum. However, our results are similar to those reported by Silveira et al (2015) for Trifolium repens, where there was saturation of foliar N from 38.8 kg ha -1 of P. In contrast, Silveira et al (2015) reported an increase in N contents with P at the edaphic level in Lotus tenuis.…”

“…In addition, the P. purpureum grass showed the highest accumulation of foliar K in both soils, with 38.88% and 26.59% for the V. Hermosa and Carolina soils, respectively (Figure 3a). When analyzing the K contents in the two soils, these were higher than the contents of 0.15% to 0.25% of foliar K reported by Silveira et al (2015) for Brachiaria grass. These foliar K contents may be associated with the K contents in the soils of the two sites; in Vista Hermosa, we found a K content of 1.15 cmol c kg -1 , whereas in Carolina, the K level was 0.69 cmol c kg -1 .…”
