Impact of legume intercropping on soil nitrogen and biomass in hybrid poplars grown as short rotation coppice

Original language description

The legumes white melilot (Melilotus albus ʻMebaʼ) and white clover (Trifolium repens ʻJuraʼ) were tested for their suitability as intercrops for fast growing poplar hybrids grown as short rotation coppice (Populus nigra × P. maximowiczii ʻMax-4ʼ, P. maximowiczii × P. trichocarpa ʻNE-42ʼ and P. trichocarpa × P. koreana ʻP-468ʼ). Legumes were sown in the established poplar plantation after its first harvest (5 years after the establishment of the plantation) and their effect on soil nitrogen, vegetation undergrowth and poplar growth was monitored for two years. All three parameters were influenced by the legume intercrops but the effect depended on the poplar clone, legume species and their interaction. In P-468 white clover reduced inter-year loss of soil nitrogen content, increased the Ellenberg indicator value for nutrients and promoted height increment. Such effect was not detected in the other two poplar hybrids probably due to insufficient establishment of clover. Plots sown with legumes and subjected to weeding exhibited remarkable differences of the understory vegetation compared to controls. The difference persisted even during the second year after legume growth had largely receded. Our results indicate a short-term potential of white clover to contribute to poplar growth, and N supply in poplar plantation(s). Further studies should explore the potential of clover intercropping from long-term perspective, with other poplar clones and under different climate-soil conditions.
