“…Muskmelon seedlings grew adequately in compost–peat (50:50, v/v) mixtures, and even better than in peat. Similar results were observed by Blaya et al and Perez‐Murcia et al Many different authors also showed higher plant yields when composts were used as organic media, instead of peat . Composts and peat showed physical properties with values similar to those considered acceptable for ‘ideal growing media’, except for the total water holding capacity, which was lower than the acceptable value – something that could be easily overcome by the frequent addition of water in low amounts …”

Composts produced are suitable components of mixed compost-peat growing media, providing a 50% substitution of peat. Furthermore, some of these composts also showed an added value as a suppressive organic medium against Fusarium wilt in muskmelon seedling, a fact probably related to high pH and pepper wastes and high content of pruning waste as initial raw materials. © 2016 Society of Chemical Industry.

“…Aunque, los altos precios de la turba de musgo (125 USD m -3 ), así como de la perlita (114 USD m -3 ) y la vermiculita (151.5 USD m -3 ), por su importación(Aguilera et al, 2016a) generan la necesidad de buscar otras alternativas con materiales regionales que permitan reemplazar o disminuir su uso(Tian et al, 2017). Además, la extracción excesiva de turba de musgo causa daños ambientales importantes en los ecosistemas donde se recolecta(Aleandri et al, 2015).Algunas opciones de sustratos se basan en residuos ganaderos (composta de estiércol vacuno), de la industria agroalimentaria (fibra de coco y de café) y forestal (corteza y aserrín de pino)(Aguilera et al, 2016a;Aguilera et al, 2016b).Revista Mexicana de Ciencias Forestales Vol. 9 (48) Julio-Agosto (2018)…”

Asegurar el éxito de los programas de reforestación requiere el uso de planta de alta calidad. El empleo de sustratos alternativos de amplia disponibilidad y bajo costo (aserrín y corteza compostada) puede ser una opción viable para su producción. En este contexto, se evaluaron cuatro sustratos (aserrín de pino crudo, corteza de pino compostada y turba de musgo), en combinación con dos fertilizantes de liberación controlada (Multicote® y Osmocote Plus®), en el crecimiento y calidad de Pinus cooperi producido en vivero. La siembra se realizó en contenedores de poliestireno de 77 cavidades, con 170 mL por cavidad. Los sustratos fueron: S1) 46 % turba + 54 % corteza; S2) 30 % turba + 20 % corteza + 50 % aserrín; S3) 25 % turba + 25 % corteza + 50 % aserrín; y S4) 20 % turba + 30 % corteza + 50 % aserrín, con Multicote® (18-06-12, N-P-K) y Osmocote Plus® (15-09-12, N-P-K). Se aplicó un diseño experimental completamente al azar con arreglo factorial 4 × 2. A los nueve meses de edad de las plantas, los mejores resultados para diámetro, biomasa total e índice de calidad de Dickson se obtuvieron con el sustrato S1: 46 % turba + 54 % corteza, con 8 g L-1 de Multicote®. Sin embargo, el sustrato S2: 30 % turba + 20 % corteza + 50 % aserrín en combinación con 8 g L-1 de Multicote® también tuvo valores aceptables; además, redujo 39.8 % los costos de producción, debido al sustrato y al fertilizante.

“…The production system of the "on farm" compost/vermicompost/biochar/digestate can be considered as a model replicable in different nurseries and environments. However, the compost/vermicompost/biochar/digestate composition may vary after each production cycle, thus requiring basic characterization for its correct use as a component of the substrate (Aleandri et al, 2015). Continuing population growth and increasing consumption are driving global food demand, with agricultural activity expanding to keep pace.…”

The modern agricultural system is wasteful, with Europe generating some 700 million tonnes of agricultural and food waste each year. In the context of the agri-food chain, the 'circular economy' aims to reduce waste while also making best use of the 'wastes' produced by using economically viable processes and procedures to increase their value. In this paper we will try to frame the key issues associated with food waste into the emerging bioeconomy and circulareconomic mode, suggesting that these three concepts are intertwined, and considering them unitarily might provide win-win solutions that minimize wastage, promote income growth and job creation, and prompt sustainable local development. In terms of performance and economic considerations, peat is in many ways an ideal constituent of soilless growing media. Peat has become the material of choice throughout plant production systems from propagation to saleable 'finished plant' material. However, the extraction of peat has well documented negative impacts on the environment; arguably the most important of these is the release of stable, sequestered carbon into the active carbon cycle, thereby exacerbating climate change. During the last 20 years, peat extraction has come under increasing scrutiny throughout Europe and particularly in the UK. This has generated an abundance of studies examining a diverse range of alternative materials (as compost, vermicompost, digestate, biochar). In the selection of new materials, environmental considerations have become as important as performance and economic cost. In this context there has been a justifiable emphasis on organic materials derived from agricultural, industrial and municipal waste streams. For future urban sustainability it is necessary to develop integrated processes, which can be part of a circular bio-economy. However the challenge still remains of simultaneously recycling the nutrients from the waste. The greenhouse horticulture applied to nutraceutical species is the ideal sector for improving the conversion rate of organic waste into food and health friendly products. On farm composting/vermicomposting/pyrolysis/anaerobic digestion and the use of the end-product to the partial substitution of peat in nursery activity allows reducing the environmental and economic costs in the production of potted plants.
