Eugenia uniflora is a fruit tree of the Myrtaceae family, native to Brazil, Argentina and Uruguay that has high potential for use in landscape environmental projects, food pharmaceutical industry. However, information on production quality seedlings still scarce. The objective was identify appropriate substrate its characteristics, relation water regime E. seedlings. experiment conducted random...

Hydroponics culture have many advantages such as increased yield, health and uniform product, conservation of water and land , better protect , control of environmental pollution and reduce of workers for cultivation. So in recently years, usage of organic and inorganic substrates obtained more important for greenhouse owners and researchers. The aim of this study was Effects of culture substra...

This paper investigates how vascular plants affect carbon flow and the formation and emission of the greenhouse gas methane (CH4) in an arctic wet tundra ecosystem in NE Greenland. We present a field experiment where we studied, in particular, how speciesspecific root exudation patterns affect the availability of acetate, a hypothesized precursor of CH4 formation. We found significantly higher ...

The laboratory tests for measuring the effects of small strain to the shear strength and maximum stiffness development of post-cyclic degradation of hemic peat are reviewed in this paper. A series of laboratory testing has been conducted to fulfil the objective of this research to study the post-cyclic behaviour of peat soil and focuses on the small strain characteristics. For this purpose, a n...

The production of forest seedlings with adequate morphological and physiological characteristics is essential for the success plantations. Substrates irrigation are major factors determining seedlings’ growth. made urban agricultural residues a sustainable alternative to peat-based substrates. In this study, we evaluated how composted sewage sludge substrates affect growth gas exchange in Cedre...

As more horticultural producers in the United States transition to organic production practices, they are challenged in finding consistent and economically viable sources of suitable potting media. Commercial, peat-based media approved for certified organic production are available and custom peat-based mixes that use certified organic fertilizers could also be used. Both of these options, howe...

Natural pipes are common in many upland blanket peats, yet little is known about pipe network morphology or pipeflow processes. Most information on soil piping comes from the shallow peaty podzols of the Welsh uplands, where monitoring suggests that pipes may be important contributors to streamflow. This paper presents information on piping and pipeflow from a deep upland blanket peat catchment...

to evaluate the effect of arbuscular mycorrhiza (glomus mosseae) under salt stress on physiological and some nutrient absorption in new guinea impatiens (impatiens hawkeri), an experiment established in complete random design with three replications (three pots for each replication) in greenhouse in shahrekord university in 2014. treatments were inoculation of substrate with three levels of arb...
