Despite a growing body of research linking bioenergy cultivation to changing patterns of biodiversity, there has been remarkably little interest in how bioenergy plantations affect key ecosystem processes underpinning important ecosystem services. In this study, we compare how the processes of predation by ground arthropods and litter decomposition varied between Short Rotation Coppice (SRC) wi...
Sycamore is a valuable tree not only economically but also ecological and culturally. Even though it has vigorous regeneration system from its stump, coppice management triggered limited formal investigations. Therefore, the present study focused on finding most suitable strategy for achieving ground coverage biomass, as well developing growth yield models sycamore maples. Using series of eight...
In this study the influence of three different tillage systems in combination with eight varying weed treatments applied within the establishment year and its effect on the final above ground leafless biomass production (after the third growing season) of short rotation coppice poplar is presented. The three tillage systems included variants with ploughing and harrowing, variants with cultivati...
Carlander, A. 2006. Assessment of microbial health hazards associated with wastewater application to willow coppice, coniferous forest and wetland systems. Doctor's dissertation. ISSN 1652-6880, ISBN 91-576-7078-1 Treatment and reuse of wastewater by irrigation of willow coppice, forest or wetlands may create new exposure routes for pathogens. This thesis summarises results from a series of fie...
The management of fertilizer is an important strategy for better nutrition and productivity eucalyptus. Therefore, the objective this research was to evaluate isolated residual effect (carryover) N, P K fertilization on macro- micronutrients in soil, leaf litter, nutritional diagnosis initial growth attributes eucalyptus a coppice system. Three experiments were carried out randomized block desi...
In recent years, fundamental changes in the ecosystems of Zagros forest structure have occurred, including the decline of brant’s oak (Quercus bratii Lindl.) that is main species in this region. So this research intends to study trees decline in relation to sylviculture, topography, and soil characteristics. For this purpose, first, parts of forest that showed oak decline were identified by fie...
