“…silver birch and Scots pine (Kuznetsova et al 2011)) a few years after plantation establishment are in agreement with previous studies (Uri et al 2003;Kuznetsova et al 2011). It highlights the importance of separating tree species and components for improved estimates of N storage in tree biomass.…”

“…Allometric biomass equations published by previous studies for young ash (Bunce 1968;Korsmo 1995;Alberti et al 2005) and black alder stands (Hughes 1971;Johansson 2000;Kuznetsova et al 2011) underestimated tree biomass at our forest by 15 to 53% and 7 to 47%, respectively. This indicates greater site productivity and tree height growth at our forest.…”

“…Kuznetsova et al (2011) also reported enhanced branch biomass allocation as well as greater height and diameter growth in 1 to 7 year old black alder plantations compared to silver birch (Betula pendula Roth) plantations in Northeast Estonia. Thus, considerable differences in biomass allocation and production among broadleaf tree species may already occur within the first decade following plantation establishment.…”

Background and Aims This study investigated initial land-use change effects on ecosystem biomass, carbon (C) and nitrogen (N) allocation and storage by comparing a recently afforested grassland with an adjacent intensively managed grassland in southern Ireland. Methods Soil C, N and fine root (<2 mm) stocks were determined from soil cores. Above ground biomass, C and N stocks were estimated from biomass clipping, inventory and allometric biomass equations developed for ash (Fraxinus excelsior L.) and black alder (Alnus glutinosa L.) in the 5-year-old forest plantation. Results Five years after grassland afforestation, the mean fine root stock of 0.31 kg m −2 in the forest was about half that of 0.64 kg m −2 in the grassland. This decrease was offset by an additional gain of 0.36 kg m −2 in tree biomass since afforestation. The above-to below ground biomass ratio shifted from 0.20 in the grassland to 1.59 in the forest. From May to October, mean net N mineralization was significantly lower in the forest compared to the grassland. Soil C and N concentrations in the 0-10 cm soil layer were significantly higher in the forest (62 mg C g −1 ; 5.7 mg N g −1 ) compared to the grassland (45 mg C g −1 ; 3.6 mg N g −1 ). However, the bulk density in the upper forest soil layer was lower than in the grassland. As a result, no differences existed between the respective total (0-30 cm depth) soil C and N stocks. Total ecosystem C and N storage was also similar for the forest (9.5 kg C m −2 ; 0.75 kg N m −2 ) and the grassland (9.3 kg C m −2 ; 0.77 kg N m −2 ). Conclusions A significant change in total ecosystem C and N following afforestation of this intensively managed grassland was not observed. Nevertheless, this study highlights immediate implications from such land-use change activities on biomass, C and N reallocation among the above-and belowground ecosystem pools which may subsequently affect ecosystem biogeochemical cycles.

Ecological benefits provided by alley cropping systems for production of woody biomass in the temperate region: a review

et al. 2012

In temperate Europe alley cropping systems which integrate strips of short rotation coppices into conventional agricultural fields (ACS) are receiving increasing attention. These systems can be used for crops and woody biomass production at the same time, enabling farmers to diversify the provision of market goods. Adding trees into the agricultural land creates various additional benefits for the farmer and society, also known as ecosystem services. However, tree-crop interactions in the temperate region have not been adequately substantiated which is identified as a drawback to the practical implementation of such systems. In order to bridge this gap, the current paper aims to present a comprehensive overview of selected ecosystem services provided by agroforestry with focus on ACS in the temperate region. The literature indicates that compared with conventional agriculture ACS have the potential to increase carbon sequestration, improve soil fertility and generally optimize the utilization of resources. Furthermore, due to their structural flexibility, ACS may help to regulate water quality, enhance biodiversity, and increase the overall productivity. ACS are shown as suitable land use systems especially for marginal sites. Based on the available data collected, we conclude that ACS are advantageous compared to conventional agriculture in many aspects, and therefore suggest that they should be implemented at a larger scale in temperate regions.

Mining activities leave large areas of post‐mining lands to be reclaimed. Increases in soil C and N pools and N availability are important to successfully reestablish trees on post‐mining land. In this study, we determined C and N concentrations and natural stable isotope of 13C and 15N in soil and plant in Mongolian pine (Pinus sylvestris L. var. mongolica Litv.) plantations 8 years after establishment on non‐mined land (NM), post‐mining land without soil amendment (NAM), and post‐mining land with soil amendment (AM) in a placer gold mining region of Northeast China. We found that the growth of Mongolian pine was significantly slower on NAM as compared with NM (decreasing by 73% in tree height and 63% in basal diameter), but tree growth improved on AM. Soil C and N concentrations, plant N concentration, and soil δ15N value decreased in the order of NM > AM > NAM, implying that soil N availability decreased in post‐mining land, but soil amendment could increase soil N availability. However, the values of δ15N in plant tissues of Mongolian pine were higher on NAM than on NM and AM, suggesting that soil inorganic N form absorbed by trees might be changed when trees were directly planted on post‐mining land with lower soil N availability. In addition, the values of δ13C in 1‐ and 2‐year‐old leaves of Mongolian pine were lowest when planted on NAM, indicating a decrease in intrinsic water‐use efficiency of Mongolian pine. Our results suggest that soil amendment helps us establish forests successfully on post‐mining lands. Copyright © 2015 John Wiley & Sons, Ltd.
