“…Coffee husk (pH = 4.8), pine-bark (4.26), coconut fiber (5.41), sewage sludge (4.36), sawdust (4.16) and peat (4.7) are characterized as highly acidic, with lower pH values than recommended for agricultural residue use. According to Abad et al (2001), the pH range considered ideal for components of substrates used for seedling production in containers would be 5.3-6.5. Considering this range for the appropriateness of the use of the materials studied, only coconut fiber would meet the requirement.…”

“…Figure 4 presents the apparent density values for materials, which reached values ranging from 50.9 to 859 kg m -3 . According to Abad et al (2001), the ideal density for substrates is less than 400 kg m -3 . Thus, the bulk densities of sewage sludge and peat only (697.3 and 859.0 kg m -3 , respectively) were greater than the maximum considered ideal.…”

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

Abstract:The main objective of this work was to identify and evaluate possible substrate alternatives or amendments to peat moss. This study involves the physical and chemical characterization and growth test of wood sawdust and wood fiber in order to evaluate their use as components of horticultural media. The carbohydrate content, C/N ratio, pH, phenolic compound, total porosity and water holding capacity were 58.9%, 425.1, 4.8, 181.8 (mg･g -1 ), 82.5% and 47.1% in wood sawdust and 41.1%, 240.8, 5.9, 29.8 (mg･g -1 ), 90.6% and 56.2% in wood fiber, respectively. Wood sawdust (K, 998.0 mg･100g -1 ; Ca, 1196.0 mg･100g -1 ; Mg, 105.6 mg･100g) and wood fiber (K, 1250.1 mg･100g -1 ; Ca, 1982.6 mg･100g -1 ; Mg, 173.1 mg･100g -1 ) showed adequate mineral elements properties compared to peat moss (K, 0.02 mg･100g -1 ; Ca, 0.57 mg･100g -1 ; Mg, 0.13 mg･100g -1 ) for their use as growing media. The mixtures of the horticultural media were prepared using different substrate as wood sawdust and wood fiber to grow Chinese cabbage (Brassica campestris L.) in a greenhouse. The seed germination, leaf area and stem height were 75%, 0.50 cm 2 and 2.8 cm in PS substrate (containing 30% peat moss, 10% perlite and 60% wood sawdust) and 95%, 0.65 cm 2 and 3.3 cm in PF substrate (containing 30% peat moss, 10% perlite and 60% wood fiber), respectively. The seed germination and stem height of the PF substrate (containing 30% peat moss, 10% perlite and 60% wood fiber) was higher than those in peat moss (control). Utilization of wood by-product can be considered as an alternative media component to substitute the widely using expensive peat moss.

This research was carried out to study the characteristics and the potential utilization of coal fly ash-based synthetic aggregates (CSA) with oil palm waste as an alternative container substrate for ornamental-plant production. CSA only, oil palm waste only, and two mixing ratios of CSA with oil palm waste at the ratio of 1:5 and 1:10 (V/V) were utilized under this study. Zeolite was utilized as a standard substrate to compare characteristics of other substrates. The physical and chemical properties of all substrates were characterized. Scanning electron microscopy (SEM) of coal fly ash and CSA were conducted in order to study the structural configuration of the CSA. Developed CSA gave an alkaline pH (9.82), high electrical conductivity (96.1 mS m -1 ), high cation concentrations, high water-holding capacity, and low bulk density (0.56 g cm -3 ) compared to zeolite. Mixing of CSA with oil palm waste at the ratio of 1:10 gave enhanced physical and chemical properties such as bulk density (0.25 g cm -3 ), particle density (1.76 g cm -3 ), air space (20.6%), total pore space (85.8%), total water-holding capacity (652 mL L -1 ), pH (6.18), and electrical conductivity (42.4 mS m -1 ), which were in the established ideal substrate range. Moreover, SEM study revealed that CSA is a dual-composite material, which had well enmeshed coal-fly ash particles in the fibrous paper-waste matrix creating porous spaces within the aggregate. The growth of French marigold (Tagetes patula), which is a popular ornamental plant in Japan, was assessed using these newly developed substrates. The mixing ratio of CSA and oil palm wastes at 1:10 reported the best maximum growth and yield parameters of French marigold, with increase in shoot fresh weight, shoot dry weight, root fresh weight, root dry weight, plant height, and number of flowers per plant by 51%, 93%, 54%, 150%, 19%, and 61%, respectively, compared to the zeolite. It is revealed that a mixture of CSA and oil palm waste at the ratio of 1:10 can be successfully utilized as an alternative container substrate for French marigold production.
