“…The final products, composts and vermicomposts, can be used as sources of organic matter for soil amendment, of nutrients for soil fertilization or as growing media constituents for soilless cultivation (González et al, 2010). In fact, in recent years vegetable crop residues have been successfully recycled through composting for horticultural purposes (Kulcu & Yaldiz, 2004;Mazuela et al, 2005;Carrión et al, 2008). Both processes can be produced at the industrial scale, which allows the disposal of large quantities of waste (Lazcano et al, 2008).…”

The feasibility of composted (C), composted plus vermicomposted (V1) and straight vermicomposted (V2) tomato crop waste as component of rooting media for Euonymus japonicus ‘Microphylla’ and Lavandula angustifolia vegetative propagation was studied. Mixes of C, V1 and V2 with coir fibre (CF) at the proportions 100:0, 75:25, 50:50, 25:75, 0:100 (v:v) were assayed. Physical, physico chemical and nutritional characteristics of all materials and mixes were determined and correlated with cutting rooting and growth performances. The compost and the two vermicomposts were markedly different from CF. They had higher bulk density and lower total porosity than CF. Compost had lower water holding capacity and shrinkage in response to drying than vermicomposts and CF. Compost and vermicomposts were alkaline materials whilst CF was almost neutral. Electrical conductivity (EC) was low in CF and vermicomposts, and high in compost due to the high mineral contents, mainly of K+, SO42– and Na+ in this material. EC and the ions contributing to it (K+, SO42–, Na+) showed highly significative inverse correlations with rooting percentage for the two species and with root and shoot growth but only for E. japonicus. Due to its high EC, compost C (average rooting = 22.5%) performed worse than vermicomposts V1 (av. rooting = 97%) and V2 (av. rooting = 98%) whilst the latter performed similarly to CF control (av. rooting = 100%). Thus vermicomposts appeared to be more appropriate than compost as rooting media constituent.

“…In Spain, more than four million tons of vegetable crop residues are generated yearly and accumulated in specific regions (Carrión et al, 2008). Composting and vermicomposting, two well-known processes for solid organic waste reclamation, are good alternatives to burning or damping organic wastes.…”

“…According to Belda et al (2013), optimal pH values fall in a range between 5.0 and 6.5. However, only the commercial substrates remained in this range, possibly due to the presetting, which is common for commercial substrates (Carrión et al 2008). Conversely, in case of controlled production in nursery and with adequate availability of nutrients in each step, it can be carried out over a wide pH range (Fornes et al 2010, Mendoza-Hernández et al 2014.…”

SUMMARYThe definition of best substrates is often difficult due to variability of results observed in different measured variables. Therefore, we defined the best substrates for Piptadenia gonoacantha seedlings production through ranking, taking into account the relative importance of each variable in seedlings quality. In this regard, 13 substrates were formulated, composed of carbonized rice husk in different grain size, coconut fiber and two commercial substrates, pine bark and vermiculite base, all of which had their physical and chemical properties evaluated. Direct seeding was held in containers of 115 cm³, remaining for 90 days in a greenhouse and 30 days in a hardening area with full sunlight. After 120 days, an assessment of height, stem diameter, shoot dry mass, root dry mass, ease of container removal, and aggregation of roots to substrate was performed. As a result, we found higher seedling growth in substrates composed of pure components, which were based on different rice husk grain size. Addition of coconut fiber provided seedlings with lower quality. Pine bark-based commercial substrates occupied the sixth and 12 th positions in substrates ranking classification.Key words: pau-jacaré, seedling production, forest seedlings quality, agricultural residues, silviculture. RESUMENLa definición del mejor sustrato es a menudo difícil debido a la variabilidad de los resultados observados en las diferentes variables medidas. Basado en esto, el objetivo fue definir los mejores sustratos para la producción de plántulas de Piptadenia gonoacantha por medio de la clasificación, teniendo en cuenta la importancia relativa de cada variable en la calidad de las plantas. Para este fin, se formularon 13 sustratos a base de cáscara de arroz carbonizado en diferentes tamaños de grano, fibra de coco y corteza de pino compostada, que tenían sus propiedades físicas y químicas evaluadas. Se realizó siembra directa en tubos de 115 cm³, permaneciendo durante 90 días en invernadero de vidrio y 30 días en zona de rustificación a pleno sol. Después de 120 días, se evaluaron la altura, el diámetro del tallo, la biomasa seca aérea, la biomasa seca de las raíces, la facilidad de extracción desde el contenedor y la agregación de las raíces en el sustrato. Como resultado, hay un mayor crecimiento de las plántulas en sustratos compuestos por componentes puros a base de diferentes tamaños de grano de cáscara de arroz. La adición de fibra de coco proporcionó una producción de plántulas con calidad inferior. Los sustratos comerciales basados en corteza de pino ocuparon la posición de sexto y duodécimo en la clasificación de los sustratos.Palabras clave: pau-jacaré, producción de plántulas, calidad de plántulas forestales, residuos agrícolas, silvicultura.

“…Es necesario, por tanto, corregir el pH del sustrato, si éste se encuentra fuera de los límites del intervalo óptimo, con el fin de que los nutrientes estén en formas solubles para satisfacer las necesidades de la planta (Fisher y Argo, 2005). Existen diferentes estrategias para reducir el pH del compost: la mezcla con otros materiales de pH ácido o neutro; la adición de ácido nítrico o fosfórico antes del establecimiento del cultivo o durante éste (Mazuela et al, 2005;Raviv, 2005); y, la adición de enmiendas de azufre y sus derivados (sulfato ferroso, principalmente) (Carrión et al, 2008;García de la Fuente et al, 2007;Mahimairaja et al, 1994Mahimairaja et al, , 1995Roig et al, 2004 (Cook y Baker, 1983;Trillas, 2002). Su aplicación puede realizarse en distintas formas: como enmienda, como sustrato o componente del mismo, o en estado líquido, empleando el extracto acuoso del compost o éste fermentado aeróbica o anaeróbicamente (Koné et al, 2010;Litterick et al, 2004).…”

“…Otra posibilidad sería la adición directa de ácidos al compost, tales como ácido nítrico o ácido fosfórico, que, además de bajar el pH del medio, aportan nitrógeno y fósforo como nutrientes (Raviv, 2005); su inconveniente, especialmente en el caso del ácido nítrico, es que implica el manejo de sustancias peligrosas. Como tercera estrategia, podrían aplicarse enmiendas minerales derivadas del azufre, destacandopor su alta eficiencia-el azufre elemental (S 0 ), que, a través de la acción de microorganismos oxidadores presentes en el compost, es oxidado hasta formar ácido sulfúrico con la consiguiente acidificación del medio (Carrión et al, 2008;García de la Fuente et al, 2007;Handreck y Black, 2002 La estabilización del pH se produjo a partir del séptimo día del ensayo, obteniéndose como valor final la media de los últimos cinco días a partir de la estabilización de éste. Se partió de un pH inicial del compost en torno a 9, disminuyendo dicho valor gradualmente, según aumentaba la concentración de ácido en la mezcla de compost y disolución valorante (sulfato ferroso), hasta alcanzar un pH final de 5,8.…”
