ABSTRACT.- The practical value of portable hand-held ion selective electrode sensors (ISE) for on-farm [NO3-] measurement to assist with crop N management of vegetable crops has been demonstrated in numerous previous studies. They provide rapid, in-situ measurement of the nitrate concentration ([NO3-]) in nutrient and soil solutions, and in petiole sap. Sample temperatures, for on-farm measurements, vary appreciably. This study evaluated the effects of sample temperature on [NO3-] measurement using two different models of a commonly used, commercially available, portable ISE meter. The temperatures (5, 10, 15, 20, and 25 °C) examined were in the range likely to be encountered in practical on-farm work. Aqueous solutions of 6, 12, and 18 mmol NO3-L-1 were prepared from KNO3, Ca(NO3)2 and NaNO3. [NO3-] was measured in three replicate samples of each of the three concentrations, made from each NO3-; compound, at each temperature. The results consistently and clearly demonstrated a strong negative linear relationship between temperature-induced errors and sample temperatures. The temperature-induced error was considerable for cooled samples, being +50% at 5 °C and +31% at 10 °C. At sample temperatures of 17-20 °C, the temperature effects were minimal. Above this range, the temperature effect caused underestimation. At 25 °C, the temperature-induced error was -24%. These results show that care must be taken to ensure that sample temperatures do not erroneously affect the measurement of [NO3-] with ISE meters. Particular care needs to be taken with both refrigerated and warmer samples.

Este trabajo compara diferentes sistemas de manejo aplicados a edad temprana sobre el desarrollo corporal, parámetros endócrinos y edad a la pubertad en terneras para carne pastoreando campo natural. Las terneras fueron asignadas a tres tratamientos: 1) Destete
precoz (DP, n = 15) a los 75±1,5 días de edad; 2) Destete tradicional (DTr, n = 14) a los 158±1,5 días de edad; 3) Destete tradicional con creep feeding (DTr+CF, n = 17). Las terneras DP y las DTr+CF recibieron un suplemento con 26±1,1 % de proteína cruda y 11,7±0,04 MJ de energía metabolizable/kg de materia seca desde los 75 a los 158±1,5 días. Las terneras DTr tuvieron una mayor ganancia de peso diario respecto a las terneras DP, asociado a mayores concentraciones de IGF-I al momento del DTr, pero la edad a la pubertad fue similar en ambos grupos. Las terneras DTr+CF (P<0,05) tuvieron una mayor ganancia de peso diario, mayores concentraciones de IGF-I al destete, fueron más pesadas y altas desde el destete hasta los 539±1,5 días (P<0,02) y la pubertad ocurrió más temprano que en las DP (P<0,05) y tendió a ocurrir antes que en las terneras DTr (P=0,06). Concluimos que la edad al destete tiene un impacto de corto plazo sobre el crecimiento corporal y las concentraciones de IGF-I, que no tienen efecto sobre la edad a la pubertad. El CF indujo un desarrollo corporal más rápido, relacionado a una manifestación más temprana de la pubertad. |
