Improving Harvesting Techniques to Ensure Sphagnum Regeneration in Chilean Peatlands Chilean J. Agric. Res.
Diaz,Maria F; Silva,Wladimir.
Sphagnum species, primarily Sphagnum magellanicum Brid., are used internationally as a substrate for horticulture. Market demands have promoted indiscriminate exploitation leading to a number of potentially negative ecological and social consequences, including disruption of Sphagnum ecosystems, changes in water storage capacity of moss wetlands affecting water supply to rural communities and reduction of biodiversity. This study proposes improvements in harvesting techniques to ensure moss regeneration and promote sustainability of moss cover in harvested areas. The aim of this study was to determine the maximum harvesting depth for moss regeneration. Samples were taken and divided into sections associated with different depths. We recorded and marked the...

Inclusion of various controlled release fertilizers in moss substrates(Sphagnum magellanicum) Ciencia e Investigación Agraria
Oberpaur,Christel; Fernández,Carolina; Délano,Guillermo; Arévalo,M.Eugenia.
The most frequently used substrate for the production of covered root seedlings is peat, the extraction of which is under scrutiny due to its negative environmental impact; however, the use of Sphagnum moss in adequate mixtures constitutes a possible alternative. Lettuce seeds (Lactuca sativa L.) were sown in Polystyrene trays (240 alveoli, 24 cm³) to test four substrates, 50% Sphagnum moss mixed with 50% humus or compost and 60% Sphagnum moss with 40% humus or compost, and commercial peat was used as a control. A dose (2.5 or 3.5 gL-1) of controlled-release fertilizer (CRF) was added to all substrates except for the control mix, and the substrates were subsequently irrigated with or without a fertilizer solution. The study was conducted under shaded...

Sphagnum magellanicum growth and productivity in Chilean anthropogenic peatlands RChHN
DÍAZ,MARÍA F; TAPIA,CAROLINA; JIMÉNEZ,PATRICIA; BACIGALUPE,LEONARDO.
Sphagnum peatlands are threatened at a global scale, not only by peat extraction, but also by Sphagnum harvesting. In Chile, dry Sphagnum moss is mainly exported for use as substrate for horticulture and orchids. Although the use of Sphagnum within Chile is limited, there are no data about its productivity and growth. These peatlands have a special microtopography with hummocks, hollows and lawns, which vary the distance of moss to the water table level. In these ecosystems, the water table is almost all year near the surface. We measured cumulative and relative growth rates and productivity during approximately one annual cycle in private Sphagnum peatlands that are being yearly harvested for commercial purposes. We evaluated the relationship between...

[[abstract]]In order to evaluate the possibility of using the commercial bark imported from New Zealand for cultivation of Phalaenopsis seedlings, the physical and chemical properties of bark were investigated. Orchid (Phal. Sogo Yukidian) seedling growth under different combinations of culture media, fertilization frequency and nutrient solution concentrations also were tested in the screen house. The results showed that the pH value of the bark ranging from 5.0 to 6.12 was not significantly different from that of sphagnum moss. However the electric conductivity (EC) and water holding capacity of the bark was lower than those of sphagnum moss. The growth performance of Phalaenopsis seedlings in bark and various mixed media was inferior to those in...
