Effect of Phosphorus Fertilization on the Chemical Composition of Lotus tenuis and Trifolium repens
One way of increasing forage yield and quality of natural pastures is through the inclusion of legumes in the grass cover. In order to achieve an appropriate crop establishment it is necessary to have an adequate availability of phosphorus (P) in the soil. Given the poor levels of this nutrient in many soils, it is necessary to fertilize. The objective of this study was to evaluate the effect of P fertilization at various doses on the content of P and nitrogen (N) in Lotus tenuis Waldst. & Kit ex. Willd. (lotus from the lowlands) and Trifolium repens L. (white clover) in a smectitic, fine, thermic Oxiaquic vertic argiudoll at Cerro Largo, Uruguay. The treatments were four phosphorus levels (0, 21,8, 43,6 and 65,4 kg P ha-1) broadcasted at seeding as triple superphosphate (0-46-0). The experimental design was randomized blocks, with eight repetitions. At 120 days post seeding, 10 plants/plot/specie were collected to determine the aerial part and root dry weight, and P and N content. P concentration in dry matter increased with P doses for both species, while N concentration showed significant differences only in T. repens.

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 nitrógeno (N) de Lotus tenuis Waldst. & Kit ex. Willd. (lotus de los bajos) y Trifolium repens L. (trébol blanco), en un Gleysol Lúvico Melánico Típico del Departamento de Cerro Largo, Uruguay. Se evaluaron cuatro niveles de P (0, 21,8, 43,6 y 65,4 kg de P.ha-1) aplicados al voleo en la siembra, como superfosfato triple (0-46-0). El diseño experimental fue de bloques al azar, con ocho repeticiones. A los 120 días post-siembra se recolectaron 10 plantas/parcela/especie, para determinar el peso seco de las partes aéreas y raíz y su contenido de P y N. La concentración de P en la materia seca aumentó con la dosis de P para ambas especies, en tanto que el contenido de N mostró diferencias significativas solo en T. repens.
