“…The characteristics of plant residues vary depending on the plant species, plant tissues, and soil chemical and physical properties, but are generally nutrient-poor and have lower EC than animal or municipal wastes (Abad et al, 2002;Garcia-Gomez et al, 2002;Benito et al, 2003;Benito et al, 2005;Benito et al, 2006;Domeño et al, 2009;Bernal et al 1998;Ingelmo et al, 1998;Hernández-Apaolaza et al, 2005;Bardhan et al, 2008;Ostos et al, 2008). Benito et al (2006) concluded that composts obtained from pruning must be mixed with other ingredients rich in nutrients, to compensate the low-nutrient level.…”

SUMMARYDue to human activity, large amounts of organic residue are generated daily. Therefore, an adequate use in agricultural activities requires the characterization of the main properties. The chemical and physical characterization is important when planning the use and management of organic residue. In this study, chemical and physical properties of charcoal, coffee husk, pine-bark, cattle manure, chicken manure, coconut fiber, sewage sludge, peat, and vermiculite were determined. The following properties were analyzed: N-NH 4 + , N-N0 3 -, and total concentrations of N, P, S, K, Ca, Mg, Mn, Zn, Cu, and B, as well as pH, Electrical Conductivity (EC) and bulk density. Coffee husk, sewage sludge, chicken manure and cattle manure were generally richer in nutrients. The EC values of these residues were also the highest (0.08 -40.6 dS m -1 ). Peat and sewage sludge had the highest bulky density. Sodium contents varied from 0 to 4.75 g kg -1 , with the highest levels in chicken manure, cattle manure and sewage sludge. Great care must be taken when establishing proportions of organic residues in the production of substrates with coffee husk, cattle or chicken manure or sewage sludge in the calculation of the applied fertilizer quantity in crop fertilization programs.Index terms: substrate, organic residue, soil contamination, residue disposal.( de: N, N-amônio, Nnitrato, P, S, K, Ca, Zn, Cu e B; foram, também, os

“…As expected, the EC decrease along the experiment for both pine bark and coconut fibre substrates. Pine bark based substrates showed pHs around 7.0 (Table 2) and the coconut fibre ones around pH 6.0, which are typical for these type of substrate (Abad et al, 2002) and adequate for woody plant container production. At the end of the experiment, no significant differences between substrates were found due to the successive watering with deionised water.…”

“…Nowadays other materials have been used as substrate, for example coconut fibres, because they have many characteristics in common with peat (Lennartsson, 1997). During the past few years this material has become commercially popular, and it is now being successfully used in different parts of the world as peat substitute for container-grown ornamental plants (Handreck, 1993;Stamps and Evans, 1997;Offord et al, 1998;Noguera et al, 2000;Abad et al, 2002).…”

Waste products such as biosolids and wood wastes have been frequently used in container production of plants. The use of biosolids in agriculture is a beneficial mean of recycling the by-products of waste-water treatment. However, care must be taken to avoid environmental or human health problems via run-off and leaching.The objective of this work is to compare the retention capacity of cadmium, lead, zinc and nitrate between pine bark (PB) and coconut fibre (F) when mixed with increasing amounts of composted sewage sludge (CSS) (0%, 15% and 30% (v/v)). Substrates were packed into leaching columns and irrigated with deionised water every 2 days. Leachates were collected during 1 month, and nitrate, Zn, Cd, Pb, EC and pH were monitored along the experiment. PB columns leached lower amount of nitrate than the coconut fibre ones. The same trend was observed for Zn, Cd and Pb. It could be said, that in order to minimize the environmental risks of using sewage sludges our results indicate that it is preferred to mix the sludge with pine bark instead than with coconut husk.

“…Manipulation of growth media is one of the strategies introduced to increase yield of ornamental plants and botanicals in general because the quality and quantity of growth media is directly proportional to the performance of the plant. James and Michael [13] as well as Bhardwaj [14] opined that growth media have direct effects on the functional rooting system and that for a plant to perform well, the growth media used must be able to reduce water content and yet retain sufficient water to reduce watering frequency, must be able to sufficiently anchor or support the plant and must be able to serve as reservoir for nutrients necessary for growth [15]. Sansevieria liberica is an ornamental plant with high medicinal values.…”

The performance of Sansevieria liberica was determined on different growth media in the nursery. The growth media used include topsoil (TS), sandy soil (SS), rice husk (RH), topsoil plus rice husk (TS+RH), sandy soil plus rice husk (SS+RH), topsoil plus sandy soil (TS+SS) and top soil plus rice husk plus sandy soil (TS+SS+RH). The media were prepared in ratio 1:1 and their effect was observed on the height, stem girth, root length, root number and leaf number after six weeks of planting. The proximate and anti-nutritional analysis of the plant as well as the pH and mineral composition of the growth media were determined. The (TS+SS) medium showed the highest performance as regard plant height, stem girth, root length, root number and leaf number as it was significantly (p<0.05) different from other media. (TS+SS) growth medium had the highest pH value of 5.88 and the S. liberica grown on it recorded higher value of the mineral contents than those grown on other media. There was strong correlation between the performance of the plant and the pH value of the growth media as reflected by the linear regression analysis. Plant grown on RH recorded highest value of the anti-nutritional component tested. Thus, the rate at which S. liberica from different growth media contain the anti-nutritional components can be arranged as RH>SS+RH>TS+RH>TS+SS. Base on the result obtained, the growth of S. liberica can be enhanced using topsoil with sandy soil as growth media.
