摘要: The aim of this study was to determine the economic, social and environmental aspects, that promote choosing an agroforestry system continuing agricultural production instead simple afforestation land. Material for collected in experimental demo field located central part Latvia (56°41 N 25°08 E) established spring 2011, nearby Skr �O veri. Two legumes - fodder galega ( Galega orientalis Lam.) 'Gale', poor-alkoloid lupine Lupinus polyphyllus L.) 'Valfrids' two perennial grass cultivars reed canary (RCG) Phalaris arundinacea 'Bamse' festulolium x Festulolium pabulare ) 'Felina' were sown between tree rows monoculture on drained mineral soil. Four different fertilisation treatments herbaceous plants control (without fertiliser), fertilisers, wastewater sludge wood ash used. Biomass, seed yield, management cost have been investigated since establishment experiment 2011. Potential benefits from growing seed, biomass possible future income non-wood goods calculated. Management system, plantation forest traditional sowing analyzed. growth together with hybrid aspen during a 5 year period has positive balance all types fertilisers. 3 had organic fertilisations at both cutting frequencies. Positive by applying fertiliser achieved only two-cut regime.
