Growers have been searching for alternative horticultural growing media components because of their desire to use sustainable resources. Biochar is a carbon-based material that has evaluated as an aggregate in peat-based soilless substrates. Additionally, silicon (Si) examined beneficial element promote plant growth and quality variety crops. However, there limited research regarding the intera...

The production of argan seedlings in nurseries is considered a crucial step for the success any forest regeneration program since it increases rate survival and growth. Therefore, substrate container play vital role seedling production, while use shade may improve soil moisture decrease water stress plant. This study aims to determine effects these factors their interactions. For this, four lev...

Peat bogs are primarily situated at mid to high latitudes and future climatic change projections indicate that these areas may become increasingly wetter and warmer. Methane emissions from peat bogs are reduced by symbiotic methane oxidizing bacteria (methanotrophs). Higher temperatures and increasing water levels will enhance methane production, but also methane oxidation. To unravel the tempe...

Open-pollinated seed was collected in 1963 from 81 trees in natural stands along the Mississippi River between Clarkscfale and Vicksburg, Mississippi. Twenty-nine of the trees were chosen for outstanding growth and form; the remaining 52 were randomly selected. Seeds were cleaned, then stored at 38° F and 25 percent relative humidity until sown on August 5. They were sown in subirrigated plant ...

Mosses in northern ecosystems are ubiquitous components of plant communities, and strongly influence nutrient, carbon and water cycling. We use literature review, synthesis and model simulations to explore the role of mosses in ecological stability and resilience. Moss community responses to disturbance showed all possible responses (increases, decreases, no change) within most disturbance cate...

Due to geochemical processes, peat soils often have elevated concentrations of trace elements, which are gradually released following drainage for agriculture. Our objectives were to use incubation temperatures to vary microbial activity in two metalliferous peats (M7 acidic peat and M3 neutral peat) from the Elba, New York region, and to use periodic leaching to assess the extent of trace elem...

Following 4 species of Mosses are reported from Hezar Masjed mountains (north of Khorasan province) as new records to Iran: Pottia lanceolata, Grimmia alpicola, Bryum badium & Ovthotrichum schimperi.The descriptions, collecting localities (habitats) and distribution of each species in the world along with their figures are given.

Air quality monitoring by using bio-indicator currently being promoted and frequently used in studies due to their advantages compared other scientific approaches. The of as a bio-monitoring air are, it remains the cheapest, most available simplest matrix for reliable atmospheric monitoring. This study was conducted determine moss ability be when expose different environments. Four environmenta...

The present paper investigates the influence of stabilization with cement, peat ash, and silica sand on permeability coefficient (kv) of compacted clay, using a novel approach to stabilize the clay with peat ash as a supplementary material of cement in the compacted and stabilized soil. In order to assess the mentioned influence, test specimens of both untreated and stabilized soil have been te...

In restored peatlands, recovery of carbon assimilation by peat-forming plants is a prerequisite for the recovery of ecosystem functioning. Restoration by rewetting may affect moss photosynthesis and respiration directly and/or through species successional turnover. To quantify the importance of the direct effects and the effects mediated by species change in boreal spruce swamp forests, we used...
