Use of basalt rock dust in comparison to dolomite to adjust the pH of a pine bark compost substrate and its response in nutrient availability
Pine bark compost substrate (SCCP) generally has a pH value below the range appropriate for container grown plants (5.3 to 6.5). In Misiones (Argentina), there are mining operations where the main residue is basaltic rock dust (PRB). The objective of this work was to evaluate the capability of PRB t...

| description | Pine bark compost substrate (SCCP) generally has a pH value below the range appropriate for container grown plants (5.3 to 6.5). In Misiones (Argentina), there are mining operations where the main residue is basaltic rock dust (PRB). The objective of this work was to evaluate the capability of PRB to adjust the pH of the SCCP in comparison to dolomite and to assess its response in the concentration of nutrients. Seven treatments were arranged: SCCP, SCCP with 1, 2 or 3 g L-1 doses of dolomite and SCCP with 0.74, 1.48 or 2.22 g L-1 of PRB. The PRB and dolomite were analysed for CaO, MgO percentage and size particles (10, 20 and 60 mesh) in order to calculate the relative power of total neutralization (PRNT). The pH and electrical conductivity (EC) for each treatment was measured at the beginning and every seven days. In addition, soluble nutrients were measured at the end of the trial. Both correctors presented high PRNT values. The suitable PRB doses to adjust the pH value were 0.74 and 1.48 g L-1. The availability of calcium, magnesium and potassium increased, and that of phosphorus, zinc, manganese, copper and iron decreased with higher pH. |

El sustrato a base de compost de corteza de pino (SCCP) generalmente posee un pH inferior al rango adecuado para las plantas cultivadas en contenedor (5,3 a 6,5). En Misiones (Argentina), existen explotaciones de rocas cuyo principal residuo es el polvo de roca basáltica (PRB). El objetivo del trabajo fue evaluar la capacidad del PRB para ajustar el pH del SCCP versus la dolomita y valorar su respuesta en la solubilidad de nutrientes. Se conformaron siete tratamientos: SCCP, SCCP con 1, 2 o 3 g L-1 de dolomita y SCCP con 0,74, 1, 48 o 2,22 g L-1 de PRB. Se analizó el porcentaje de CaO, MgO y tamaño de partículas (10, 20 y 60 mesh) en PRB y dolomita para calcular el poder relativo de neutralización total (PRNT). El pH y la CE de cada tratamiento fueron medidos al inicio y cada siete días. Se midieron los nutrientes solubles al finalizar el ensayo. Ambos correctores presentaron altos valores de PRNT. Las dosis de PRB adecuadas para ajustar el pH fueron 0,74 y 1,48 g L-1. La disponibilidad de calcio, magnesio y potasio se incrementó, y la de fósforo, zinc, manganeso, cobre y hierro disminuyó con la elevación del pH.
