Descripción
The decanted phosphate (DP) is an environmental liability for the fertilizer industries and its use as a phosphate fertilizer has been suggested in agriculture. However, there are few researches that studies its efficiency. In this sense, this experiment was conducted in a greenhouse with the main objective to evaluate the agronomic efficiency and the relative economic efficiency of decanted phosphate (DP) in the presence and absence of lime during three growth periods of Brachiaria brizantha cv. Marandu (marandu grass). In addition, the critical levels of P were determined in soil and shoots of plants. The indices Equivalent Triple Superphosphate medium (EqTS medium) e Relative Economic Efficiency (REE) were calculated in order to evaluate the efficiency of DP and triple superphosphate (TS). The critical levels of P were set when relative production was 90%. The DP efficiency indices were more than 100% when not applied liming. The liming reduces the agronomic and economic efficiency of DP. The P critical levels in soil and shoots of the marandu grass were 15 mg dm-3 and 1.2 g kg-1, respectively.
El fosfato decantado (FD) es una responsabilidad ambiental para las industrias de fertilizantes y se ha sugerido su uso como fertilizante de fosfato en la agricultura. Sin embargo, hay pocas investigaciones que estudien su eficacia. En este sentido, este experimento se realizó en un invernadero con el objetivo principal de evaluar la eficiencia agronómica y la eficiencia económica relativa del fosfato decantado (FD) en presencia y ausencia de cal durante tres períodos de crecimiento de Brachiaria brizantha cv. Marandu (hierba marandu). Los niveles críticos de P se determinaron en el suelo y los brotes de las plantas. El índice equivalente superfosfato triple medio (EqST medio) y la eficiencia económica relativa (EER) se calcularon para evaluar la eficacia de FD y superfosfato triple (ST). Los niveles críticos de P se establecieron cuando la producción relativa fue del 90%. Los índices de eficiencia del FD fueron más del 100% cuando no se aplicó el encalado. El encalado reduce la eficiencia agronómica y económica de FD. Los niveles críticos de P en el suelo y en la parte aérea de la hierba marandu fueron 15 mg dm-3 y 1,2 g kg-1, respectivamente.
