| Need for reducing peat extractions together with the need for recycling organic sub-product as substrate components requires a comparation of final properties of eco-compatible substrates made of residual materials. In this work a comparation of fibrous material; coconut fiber (FC and pine bark (CP) as substrate components against a fibrous peat (TF) taken as control. Coconut fiber is made mainly of particles less than 1mm and thus has an average pore size too small resulting in a large water retention and reduced aeration. Pine bark is also dominated by particles less than 1 mm, but less than coconut fiber and with more heterogeneity what slightly reduces substrate porosity. Peat is also heterogeneous, what can lead to alteration of hydrophysic properties. FC as well as CP show a smaller aeration capacity than TF due to smaller thickness index. However, coconut fiber, with a thickness index significantly smaller than that of the pine bark presents an aeration capacity significantly higher. Both substrates under study show pH values in the recommended range. Although FC shows a higher value than CP, which is slightly acidic, peat without liming has even higher acidity. Electrical conductivity of FC has been described by some authors as a limiting factor for growth. Nonetheless EC values have been reduced due to improvement of coconut fiber processing. For this reason all the substrates under study are adequate for growing media | |
