description |
Dairy production systems produce surpluses of nitrogen (N) and phosphorus (P) that are excreted in urine and feces, which increase the risk of contamination of soil and water. The objective of this study was to evaluate the potential of the reuse of nutrients present in excreta produced in dairy farms facilities as organic fertilizers by the calculation of (N) and (P) balances and to determine which feed component has a major influence in its variability. During 2006/2007, samples from all feed components of the milking cows (MC) were collected and analyzed in two grazing dairy farms (Castelli, Buenos Aires), with 241 (T1) and 91 (T2) MC, respectively. Nutrient balances were calculated by the difference between inputs (feeds) and outputs (milk) for each mineral. Daily permanence of MC was considered, in order to establish the balance excess that is transferred to the milking area. Nutrients deposited in dairy facilities by MC were between 1.47 to 2.61 kg N/MC/month and 0.22 to 0.45 kg P/MC/month and 5,420 kg N/year and 883 kg P/year (T1) and 2,126 kg N/year and 362 kg P/year (T2). Models estimated by simple linear regression showed that more than 79 % of the variability was explained by forage.\n |

Herrero, M.A. Orlando, A.A. Flores, M. Charlón, V. 2009 Los sistemas de producción de leche originan excedentes de nitrógeno (N) y fósforo (P) vía heces y orina que incrementan el riesgo de contaminación de suelos y aguas. El objetivo fue evaluar el potencial de reutilización de nutrientes en excretas depositadas en instalaciones de ordeño como fertilizantes orgánicos, mediante el cálculo de los balances de (N) y (P), determinándose el alimento que tiene mayor influencia en su variabilidad. En dos tambos de base pastoril (Castelli, Buenos Aires), con 241 (T1) y 91 (T2) vacas en ordeño (VO), respectivamente, se recolectaron y analizaron, durante 2006/2007, muestras de alimentos componentes de la ración de VO. Los balances se calcularon por diferencias entre ingresos (alimento) y egresos (leche) para cada mineral. Para establecer la transferencia de nutrientes, se consideró el tiempo de permanenecia diario de los animales en el ordeño. Los nutrientes depositados en la instalación de ordeño fueron de 1,47 a 2,61 kg N/VO/mes y de 0,22 a 0,45 kg P/VO/mes y de 5.420 kg N/año y 883 kg P/año (T1); y 2.126 kg N/año y 362 kg P/año (T2). Los modelos estimados por regresión lineal simple mostraron que más del 79% de la variabilidad queda explicada por el forraje. application/pdf 1514-6634 (impreso) 1668-3498 (en línea) estiércol nutrientes producción lechera reutilización manure nutrients dairy farm reutilization spa Universidad de Buenos Aires.
