| description | The physical and chemical characteristics of the substrates are important to obtain a nursery plant with adequate morphological characteristics. Three substrates of current use in forest nurseries were characterized: S1: moss peat, vermiculite and perlite; S2: composted bark, peat moss and sawdust and S3: pine sawdust, moss peat and composted bark, all in 3: 1: 1 vol proportion, to which 8 g L-1 of Osmocote® fertilizer of 8 - 9 months of release was added. They were used to produce Pinus greggii var. australis Donahue & Lopez. The porosity, pH, electrical conductivity and carbon/nitrogen ratio were evaluated before and after plant production, while granulometry, retention curves and water release only before production. The initial and final ranges of total porosity, aeration and water retention were 77% - 83%; 19% - 27% and 54% - 63%, respectively. In all substrates the aeration porosity decreased, and the water retention increased at the end. The readily available water varied from 19% to 30%, higher in S3. According to the granulometry, the largest proportion of particles was from 0.26 mm - 0.75 mm in diameter. The initial (4.8-5.3) and final (6.3-6.7) pH values are in the acid range. The initial EC was 0.9 dS - 1.7 dS, lower than the end one of 1.7 dS - 2.4 dS. The C/N ratio was different for the three substrates; S1 presented the lowest value (159), S2 with 537 and S3 the largest (613). The alternative substrates evaluated have suitable characteristics to be used in the production of forest plant and to replace the use of peat moss. |

Las características físicas y químicas de los sustratos son importantes para obtener planta en vivero con características morfológicas adecuadas. Se caracterizaron tres sustratos de uso actual en viveros forestales: S1: turba de musgo, vermiculita y perlita; S2: corteza compostada, turba de musgo y aserrín y S3: aserrín de pino, turba de musgo y corteza compostada, todas en proporción 3:1:1 vol., a los cuales se les agregaron 8 g L-1 de fertilizante Osmocote® de 8 meses – 9 meses de liberación. Se utilizaron para la producción de Pinus greggii var. australis Donahue & López. Las características porosidad, pH, conductividad eléctrica y relación carbono/nitrógeno se evaluaron antes y después de la producción de planta, mientras que la granulometría, curvas de retención y liberación de agua solamente antes de la producción. Los intervalos iniciales y finales de porosidad total, aireación y retención de agua fueron de 77% - 83%; 19% - 27% y 54% - 63%, respectivamente. En todos los sustratos la porosidad de aireación disminuyó y la de retención de agua aumentó al final. El agua fácilmente disponible varió de 19% a 30%, S3 presentó el mayor porcentaje. En la granulometría, la mayor proporción de partículas se encontró en diámetros de 0.26 mm a 0.75 mm. Los valores de pH iniciales (4.8 - 5.3) y finales (6.3 - 6.7) fueron ácidos; la CE inicial fue de 0.9 dS - 1.7 dS, menor que la final de 1.7 dS - 2.4 dS. La relación carbono/nitrógeno fue diferente para los tres sustratos, S1 presentó el menor valor (159), S2 con 537 y S3 el mayor (613). Los sustratos alternativos evaluados presentaron características adecuadas para ser utilizados en la producción de planta forestal y sustituir al compuesto por turba de musgo.
