Total phosphorus determination in agricultural amendments by dry and wet digestion

Medición de fósforo total en enmiendas agrícolas por digestión seca y húmeda

Total phosphorus determination in agricultural amendments by dry and wet digestion

Abstract

The objective was to compare wet and dry digestions for the treatment of agricultural amendments for the subsequent determination of total phosphorus. The amendments evaluated included two samples of compost, two of bokashi, one of leonardite, two of commercial substrates, and one of phosphate rock. Dry digestion involved incineration of the sample at 550 °C for 4 hours. The results suggest that both methods lead to pragmatically non-different total phosphorus values, however, those from dry digestion tend to be slightly higher than those from wet digestion. These observations are true regardless of the organic matter mass of the agricultural amendment evaluated. A greater number of experimental trials will be undertaken to reach conclusive results.

El propósito del trabajo fue comparar las digestiones húmeda y seca para el tratamiento de enmiendas agrícolas para la sucesiva determinación de fósforo total; dos muestras de compost, dos de bokashi, una de leonardita, dos de sustratos comerciales y una de roca fosfórica fueron evaluadas. La digestión seca involucró una incineración de la muestra a 550 °C por 4 h. Los resultados sugieren que ambos métodos conducen a valores de fósforo total pragmáticamente no diferentes, no obstante, los de la digestión seca tienden a ser ligeramente más altos que los de la digestión húmeda; esto es verdadero indistintamente del contenido de materia orgánica de la enmienda agrícola. Los resultados no son concluyentes; mayor indagación tendrá lugar.
