“…Aeration, pH and cation-exchange capacity are important aspects to be considered prior to the election of substrates for seedling production [18]. Composting of residual materials such pine bark is a common recycling practise for obtaining low-cost substrates suitable to produce ornamental and forest seedlings in nurseries [17,33]. Nevertheless, the effects of this type of substrates on the mycorrhizal status of forest seedlings produced in nursery are poorly documented.…”

-Spore inocula of Melanogaster ambiguus (Vittad.) Tul. & C. Tul., Pisolithus tinctorius (Pers.) Coker & Couch, Rhizopogon luteolus Fr., Rhizopogon roseolus (Corda) Th. M. Fr. and Scleroderma verrucosum (Bull.) Pers., and two substrates (a mixture of peat-vermiculite and a mixture of peat-composted pine bark) were evaluated for producing mycorrhizal Pinus pinea L. seedlings in a commercial nursery in NE Spain. Inocula of all fungi were effective to obtain containerised mycorrhizal P. pinea seedlings although seedling mycorrhization rates were reduced in the peat/pine-bark mixture. Neither inoculation nor the type of substrate modified the first-year growth of seedlings. Rhizopogon spp. increased the levels of N and P and, in general inoculation reduced the concentration of Mn in needles. Symptoms of chlorosis were detected in all seedlings growing in the peat/pine-bark mixture, probably due to nutritional deficiencies caused by the substrate high pH. Among the fungi tested, R. roseolus is proposed as the best candidate for its application in nursery inoculation programmes destined to produced containerised mycorrhizal P. pinea. , et deux substrats (un mélange de tourbe-vermiculite et un mélange de tourbe-écorce compostée de pin) ont été évalués pour produire des jeunes plants mycorhizés de Pinus pinea L. dans une pépinière commerciale au Nord-Est de l'Espagne. Les inoculums de tous les champignons ont été efficaces pour obtenir des semis mycorhizés de pin pignon en conteneur, bien que les taux de mycorhization ont diminué dans le substrat vermiculite-écorce de pin. Ni l'inoculation ni le type de substrat n'ont modifié la croissance en première année des jeunes plants. Les espèces de Rhizopogon ont augmenté les niveaux d'azote et de phosphore dans les aiguilles des plants et, en général, l'inoculation a réduit la teneur en manganèse de ces feuilles. Des symptômes de chlorose ont été détectés dans tous les plants croissant dans le substrat vermiculiteécorce de pin, probablement en raison des carences nutritionnelles provoquées par le pH élevé du substrat. Parmi les champignons étudiés, on propose R. roseolus comme le meilleur candidat pour son application dans des programmes d'inoculation en pépinière destinés à produire des plants de pin pignon mycorhizés en conteneur.Pinus pinea / substrat / mycorhization / champignons ectomycorhiziens / production des semis en pépinière

“…In general, all the substrates, except control (T1), showed pH and EC values higher than those established in optimal range (5.2-6.3 and < 0.5 dS m -1 , respectively; Abad et al, 2001;Noguera et al, 2003;Sánchez-Monedero et al, 2004). The increase in EC could be due to a greater concentration of soluble salts and nutrients, as shown in Table 3.…”

This experiment was designed to characterize the physical and chemical properties of six crop's media obtained by mixing different percentages (v/v) of peat, perlite, coconut coir dust, and vermicompost (end-product of the breakdown of organic matter of crop residues mixed with re-used coconut coir dust by Eisenia fetida) and to evaluate the tomato (Solanum lycopersicum cv. cumquat) seedling growth in this media. The treatments were: T1 (75% peat and 25% perlite), T2 (25% peat, 25% coconut coir dust, 25% vermicompost and 25% perlite), T3 (50% peat, 25% vermicompost and 25% perlite), T4 (25% peat, 50% vermicompost and 25% perlite), T5 (50% coconut coir dust, 25% vermicompost and 25% perlite), T6 (25% coconut coir dust, 50% vermicompost and 25% perlite). The electrical conductivity, pH, bulk density and water-soluble elements, contained in the substrate, increased with increasing amounts of vermicompost in the substrate, whereas the total porosity, easily available water and total water holding capacity decreased significantly with increasing amounts of vermicompost. Stem length and leaf area of tomato seedlings were higher in the substrate without vermicompost (T1) but no significant differences were found between substrates with vermicompost. No significant difference was found in the production of roots dry weight in all treatments; this is a very important result, because good quality of root system is the main goal in seedbeds. There are not clear relationships between the increase of vermicompost in mixtures and nutrient contents in stems and leaves.Additional key words: bioproductive variables; Eisenia fetida; seedling; Solanum lycopersicum; vegetable crop waste; water:air relationships. Resumen Caracterización y empleo de un vermicompost de residuos vegetales como componente alternativo de sustratos en semilleros hortícolasEste experimento se diseñó para caracterizar las propiedades físicas y químicas de seis medios de cultivo diferentes, obtenidos por la mezcla, en diferentes proporciones (v:v), de turba, perlita, fibra de coco y vermicompost (producto final obtenido de la degradación de restos hortícolas mezclado con fibra de coco reutilizada a través de la acción de Eisenia fetida) y evaluar el crecimiento de plántulas de tomate (Solanum lycopersicum cv. cumquat) en estos sustratos. Los tratamientos fueron: T1 (75% turba y 25% perlita), T2 (25% turba, 25% fibra de coco, 25% vermicompost y 25% perlita), T3 (50% turba, 25% vermicompost y 25% perlita), T4 (25% turba, 50% vermicompost y 25% perlita), T5 (50% fibra de coco, 25% vermicompost y 25% perlita), T6 (25% fibra de coco, 50% vermicompost y 25% perlita). La conductividad eléctrica, pH, densidad aparente y los elementos solubles contenidos en los sustratos aumentaron a medida que se aumentó la cantidad de vermicompost, mientras que la porosidad total y la cantidad de agua total y fácilmente asimilable, decreció significativamente al incrementar la cantidad de vermicompost. La longitud del tallo y el área foliar fueron mayores en el sustrato que...

“…Because environmental care and economic profit to the grower are of paramount importance, it was important to see if this re-use of alternative substrate would be viable in Mediterranean conditions. Bulk density is a relevant substrate physical propriety, because this allows easier transportation of crop units in the greenhouse industry (Abad et al, 2004). The new substrates, before reutilization, were within the limit of optimal range (Urrestarazu et al, 2005b); in fact, this is the major disadvantage for transport in comparison to other more popular substrates such as rockwool and perlite Urrestarazu et al, 2005b).…”
