The natural carbon storage function of peatland ecosystems can be severely affected by the abandonment of peat extraction, influencing peatland drainage, leading to large and persistent sources of atmospheric CO2. Moreover, these cutover peatlands have a low and variable water table position and high tension at the surface, creating harsh ecohydrological conditions for vegetation re-establishme...

Peat use in horticulture is associated with a large ecological footprint. the predominant growing media Europe. Modern cropping systems rely heavily on dynamic interactions of crop microorganisms and yet, search for sustainable peat-alternatives, microbiome has often been ignored. In mushroom cultivation, peat prime determinant productivity, form casing soil which supplies beneficial microbes. ...

to evaluate yield and some quantitave and qualitative characteristics of tomato cultivars in warm climate of southern provinces of iran and to determine suitable cultivars for these regions, sixteen cultivars were evaluated in an experiment using randomized complete block design with three replications in minab, hormozgan province. seeds were sown in 105 cells tray cultures containing peat moss...

The aim of this study was to develop a systematic quality index for application in the cultivation of Agaricus bisporus (Lange) Imbach mushrooms, based on the physical, chemical and biological properties (indicators) of the compost and casing layers (factors). The relative importance (weight) of each of the factors and indicators, their normalized scores, the quality index values and the correl...

This experiment was performed to investigate the effect of Azolla and rice straw mixed compost in peat substitution on Dieffenbachia amoena. Factorial experiment based on a completely randomized design with two factors of nutrient solution in 2 levels (1- without solution, 2- with 130 mg N/ l, 32 mg P /l and 117 mg K/ l) and 5 levels of Azolla and rice straw mixed compost (zero, 15, 30, 45 and ...

Peat moss is the most widely used source of organic matter for growing horticultural crops in the United States. The demand for peat as a substrate constituent for bedding and pot plants has remarkably increased in recent years, thus reducing the availability and increasing cost (Nappi and Barberis, 1993). Composts may serve as qualitatively and economically as competitive alternative sources o...

the dormancy characteristics and optimum conditions for seed germination of alstroemeria ligtu had not been explained. in vitro and in vivo alstroemeria (a. ligtu hybrid) seed germination tests were conducted in a randomized completely design at two different treatments (gibberellic acid (ga3) 0, 100, 200 and 400 mg/l with and without stratification in 5±1oc) in four replications. seeds were pl...

this study was conducted to evaluate different nutrient solutions effects on agria potato mini-tubers production under aeroponic system. the experiment was conducted in the laboratory and greenhouse of ardabil sabalan behparvar company in 2013. four recommended nutrient solutions including: lommen and struik (1992), kang and han (2005), otazu (2010) and hoagland and arnon (1950) were used in a ...

The specific objectives of this experiment were to investigate the effects of adding 10% or 30% corn dried distillers grains with solubles (DDGS) to the dairy cow diet and the effects of bedding type (wood shavings, straw or peat moss) in dairy slurry on fugitive CH₄ emissions. The addition of DDGS10 to the dairy cow diet significantly increased (29%) the daily amount of fat excreted in slurry ...

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...
