The energy use of residues from agriculture, forestry, and solid waste can foster the transition towards a more renewable supply. This paper analyzes potential above-mentioned sources for applications in Kosovo. analysis is based on statistical data different studies reports, analyzing calculating them to determine theoretical biomass potential. Kosovo increase its self-sufficiency by taking advantage rich but under-utilized sources. novelty study this area, considering lignite-dominated heat electricity consumption available special literature. According our estimates, 6.13 million tons/year, while should be around 4.57 including approximately 74.6% biomass, which used needs (heating electricity). Based calculations, usable shows as an source with high Kosovo; share very low, it reasonable grow both environmental economic reasons.

This article compares different production, economic, and selected environmental aspects of agroforestry systems in a standard (alley cropping) newly proposed design with fast-growing trees grown short-rotation coppice. Our models (AFSs) are as follows: (i) alley cropping AFS cherry walnut single rows (tree strips) 28 m-wide arable fields between them (crop strips), (ii) coppiced tree belt poplars willows 25 strips). To evaluate the production characteristics trees, we used yield curves from experimental plantations conditions Czech Republic previous research projects. Cost data were collected long-term combined current operation energy prices. The presents an economic methodology for assessing competitiveness biomass AFSs under identified market conditions. results show that coppice can have similar annual crops if on suitable sites appropriate quality agronomy. In comparison, fruit would not be economically viable farmers without significant subsidy establishment maintenance first years after establishment. Concerning latest political developments, product SRC (energy woodchips) evaluated strategic, increasing producer’s independence purchased fuels.

Abstract Fine roots (< 2 mm), which play a critical role in water and nutrient uptake, are an important component of the ecosystem carbon cycle often have higher productivity than above-ground parts. The objective this study is to investigate effect soil availability on distribution fine annual production turnover rate. was conducted throughfall reduction experiment established coppiced plantation at Czech Republic. vertical root biomass were correlated with moisture early season. Low levels (i.e. 20%) corresponded greater proportion depth. Understanding these responses may be beneficial enhance input deeper layers thus potentially sequestration by manipulating topsoil through introducing phenology understory species into bioenergy or agroforestry setups.
