| description | The use of soil in potting production difficult the crop management and involves the depletion of a nonrenewable resource. Therefore, is necessary to find alternatives for replacement. The objective of this study was to formulate substrates from pine bark (C), leaves of pine (P) and subtropical peat (T) to evaluate their physicochemical properties and quality for growing flowering plants in pots. Seven formulated substrates were evaluated: 1) 1C:1P:1T, 2) 2C:1P:1T, 3) 1C:2P:2T, 4) 2C:1P:2T, 5) 2C:2P:1T, 6) 1C:4P:2T y 7) 2C:4P:1T, one local substrate (leaves of pine + subtropical peat + mineral soil) and one commercial
substrate (Blonde and black peat + perlite + vermiculite). Bulk density, total pore space (TPS), water holding capacity (WHC), pore air (PA), particle size, pH and electrical conductivity (EC) was analyzed. Was performed a trial with Viola tricolor var . Yellow, one with Petunia hybrida var. White and one with Salvia splendes var. red. Each trial was composed of nine treatments (substrates evaluated) and 10 repetitions. At the end of the trials the number of buds and flowers, length and stem diameter, shoot and root dry mass were measured. The formulated and commercial substrate presented low bulk density (<0.4 g cm-3). The local substrate was noted for having the highest bulk density and percentage in the size fraction <1 mm due to the presence of soil in its formulation. The particle size >3.35 mm was higher in the substrate 6, 7 and commercial substrate; this explains the high percentage of PA in the first two. The substrates 6 and 7 showed the lowest values in the percentage of the fraction <1 mm, coinciding with lower CRA. All substrates had a suitable pH and EC values (pH: 5.5 – 6.3 and EC: < 1dS m-1 (1+5 v/v)). The substrates formulated obtained floral seedlings quality, but the substrates 1, 2, 3, 4 and 5 were highlighted to achieve greater absolute value in most variables. These substrates had a more balanced water/air ratio (PA <50% and CRA> 35%). |

The substrates formulated obtained floral seedlings quality, but the substrates 1, 2, 3, 4 and 5 were highlighted to achieve greater absolute value in most variables. These substrates had a more balanced water/air ratio (PA <50% and CRA> 35%). El uso de suelo para la producción en macetas dificulta el manejo del cultivo e implica el agotamiento de un recurso no renovable. Esto genera la necesidad de encontrar alternativas para su reemplazo. El objetivo de este trabajo fue formular sustratos a partir de corteza de pino (C), pinocha (P) y turba subtropical (T) para evaluar sus propiedades físico-químicas y verificar su calidad para el cultivo de plantas florales en macetas. Se evaluaron siete sustratos formulados: 1) 1C:1P:1T, 2) 2C:1P:1T,3) 1C:2P:2T, 4) 2C:1P:2T, 5) 2C:2P:1T, 6) 1C:4P:2T y 7) 2C:4P:1T, un sustrato local (Pinocha + turba subtropical + suelo mineral) y uno comercial (Turba rubia y negra + perlita + vermiculita). En todos se analizó densidad aparente, espacio poroso total (EPT), capacidad de retención de agua (CRA), porosidad de aire (PA), granulometría, pH y conductividad eléctrica (CE). Se realizó un ensayo con Viola tricolor var. Yellow, otro con Petunia hybrida var. White y otro con Salvia splendes var. rojo. Cada uno de ellos constó de nueve tratamientos (sustratos evaluados) y 10 repeticiones. Al finalizar los ensayos se contabilizaron los pimpollos y flores, longitud y diámetro del tallo, masa seca aérea y radicular. Los sustratos formulados y el comercial presentaron baja densidad aparente (<0,4 g cm-3). El sustrato local tuvo la mayor densidad aparente y porcentaje en la fracción granulométrica <1 mm debido a la presencia de suelo en su formulación. La fracción granulométrica >3,35 mm fue mayor en el sustrato 6, 7 y comercial, esto explicó el alto porcentaje de PA en los dos primeros. Los sustratos 6 y 7 presentaron los menores valores en el porcentaje de la fracción <1 mm, coincidiendo con su menor CRA. El pH y la CE de todos los sustratos fueron adecuados (pH: 5,5-6,3 y CE: <1dS m-1 (1+5 v/v)). Los sustratos formulados produjeron plantines florales de calidad, pero se destacaron los sustratos 1, 2, 3, 4 y 5 por lograr mayor valor absoluto en la mayoría de las variables. Estos sustratos presentaron una relación agua/aire más equilibrada (PA <50% y de CRA >35%). INTA, Instituto de Floricultura Fil: Barbaro, Lorena Alejandra.
