“…Mean distribution of the aggregate media showed that fraction between 5.60 and 2.00 mm was the most abundant fraction in all types of synthetic aggregates (Table 1). An excess of fines in a substrate clogs pores, increases non-plant-available water holding capacity and decreases air filled porosity (Spiers & Fietje, 2000). Therefore, these synthetic aggregates which are having higher percentage of larger-sized particles can be utilized to enhance the properties of problematic soils having higher finer particles to improve its porosity and hydraulic conductivity.…”

“…However, the use of compost as a substrate and/or substrate component can also have certain limitations, mainly in relation to physico-chemical and/ or physical restrictions. Some of these restrictions are high salt content (Ribeiro et al, 2000;Sánchez-Monedero et al, 2004;Castillo et al, 2004), unsuitable physical properties (Raviv, 1998;Spiers and Fietje, 2000) and variable quality and composition (Hicklenton et al, 2001). However, using compost mixtures with peat can minimize these negative characteristics (Raviv et al, 1986).…”

253-264. The aim of this study was to evaluate the economic feasibility of using compost made from anaerobically digested cattle slurries in a commercial nursery. Using a comparative cost analysis, commercial peat substrate growing media has been partially substituted with increasing proportions of compost (25, 50 and 75% v/v of compost). This experiment was intended to establish the conditions under which the use of these composts is feasible and competitive relative to commercial peat, at both agronomic and economic levels. Neither the quality of germination nor the vegetative development of the seedlings selected for the experiment (tomato, melon and pepper) were compromised, which was a necessary condition of peat substitution. In addition, the economic effects of using alternative compost media instead of peat alone have been quantified. The results showed that the most suitable scenario from an agronomic standpoint is to substitute 25% of the peat with compost because higher proportions of compost in the growing media are more limiting, especially for the tomato crop. At an economic level, reductions of up to 43% of the substrate cost and a 4.6% improvement in the commercial contribution margin for a company in this sector resulted from 50% peat substitution.

“…Using waste materials, most of them locally produced, as soilless growing media has been the subject of an important number of studies, especially as an alternative to peat for ornamental potted plants (e.g., Ingelmo et al, 1997;Offord et al, 1998;Lao and Jiménez, 2004a,b), and less frequently for vegetable production (Shinohara et al, 1999;Ball et al, 2000) and even for tomato transplant production (Ozores-Hampton et al, 1999). However, it has been suggested that certain types of compost alone are unsuitable as growing media due to unacceptably high salt and pH content (Spiers and Fietje, 2000), in particular when immature, unstable compost is used (Ozores-Hampton et al, 1999). Another disadvantage of the use of compost as substrate is that it is a very heterogeneous material and therefore needs to be amended so that it can be used as substrate Urrestarazu et al, 2001;Urrestarazu et al, 2003;Sanchez-Monedero et al, 2004;Carrión et al, 2005;Mazuela et al, 2005;Mazuela et al, 2010)).…”
