Vermicompost produced from sugarcane bagasse (SBV) or sawdust (S) were substituted at a range of different concentration in soilless bedding plant container medium, as a peat: vermiculite: perlite (6:3:1), to evaluate their effects on the growth of Dieffenbachia amoena in the greenhouse. Dieffenbachia amoena was grown in container medium PE: VE: P (6:3:1), in that peat substituted with 0%, 10%,...

One important assumption in applying 210Pb-dating is that atmospherically deposited 210Pb is immobilized in the peat or sediment column. This assumption has been challenged widely, but has never been evaluated experimentally. We evaluated Pb mobility and the chemical forms in which Pb is stabilized in peat profiles by adding either soluble or particulate Pb to intact peat cores that were mainta...

Morphological changes that take place in peat cultures of several species of rhizobia were examined. These changes seemed to be associated with enhanced survival of cells in peat and after inoculation onto plastic beads, which were used as a model system for seeds. Cell wall changes, in which the periplasmic space appeared to be occluded with electron-dense material, were observed in Rhizobium ...

Abstract The Piedemonte Llanero Basin is located on the eastern side of Eastern Cordillera Colombian Andes. It has been subject numerous geological studies carried out for oil sector, mainly. This study presents coal-petrographical features 15 coal seams four formations from Late Cretaceous to Middle Miocene (Chipaque formation, Palmichal group, Arcillas del Limbo and San Fernando formation). A...

Background: The composition of the planting beds and its microorganisms has a very important role on the establishment, growth and phytochemical performance of medicinal plants. Objective: The aim of this study was to determine the effect of different planting beds and inoculation of mycorrhizal fungus on the changes of stevioside, rebaudioside, and morpho-physiological traits of stevia. Meth...

Due to the econemic and envaironmental limitiation in the use of peat moss as a growth medium of ornamental plants, researchers seek an apporiate alternative in flower and plants industry. Zeolite because of the high capacity of water holding and cations enchange, has an ability in the replacement  of peat moss. At this research, the posibility subtitution of peat moss by zeolite as a growth me...

casing soil is one of the most important indicators of button mushroom production, which has a direct impact on the size and performance. due to the easy availability of resources for the production of vermicompost this mix can be used alternative of peat to button mushroom production. this study was conducted with nine treatments and three replications in¬¬ a completely randomized design at th...
