“…In agro-forestry systems, SOC content was higher within close proximity of trees, which was related to litter fall (Thevathasan et al 2004;Bambrick et al 2010). Hence, the choice of tree species can affect the heterogeneity of SOC distributed in the system (Bambrick et al 2010).…”

“…According to George et al (2012) plant diversity, productivity and carbon sequestration are interconnected. Carbon sequestration was found to be significantly higher in more diverse agroforestry systems compared to conventional crop systems (Thevathasan et al 2004). …”

“…In agroforestry systems higher earthworm abundance was measured near tree rows (Thevathasan et al 2004), which represent undisturbed habitats with higher SOC contents. In a wheat-clover intercropping system, with constant clover cover, found the absence of tillage but particularly a constant supply of nitrogen rich plant residues to be beneficial to earthworm populations.…”

“…Agroforestry practices that are currently being researched in North America include shelterbelts, windbreaks, silvopastoral systems, forest farming systems, integrated riparian forest systems, and tree-based intercropping systems [16][17][18]. Over the past 25 years, investigations on tree-based intercropping systems in southern Ontario have discovered several complementary biophysical interactions associated with this land-use system [18].…”

Production of biomass for bioenergy will depend on the sustainability of the production resource-base: the soil, water, air and the diversity of the ecosystem as a whole. For soil, potential sustainability indicators, including soil nitrogen and phosphorus, total organic matter, components associated with soil erosion and bulk density are discussed. Indicators related to the water resource water quality, water availability index, nitrate levels in water and biological oxygen demand are also discussed. Greenhouse gases and their sequestration potentials are discussed for maintaining atmospheric air quality. For biodiversity, a biodiversity index and soil biota index were selected as potential indicators. In addition to the production resource-base, the paper also discusses the importance of economic and social sustainability indices. To summarize, we are suggesting that a common method of visualizing the above indicated indices is to generate amoeba diagrams. This paper also provides a review on the term 'sustainability' and specific indicators, with metrics where possible, are described as candidates for inclusion as potential indicators appropriate for agroforestry based bioenergy systems in Canada. Three agroforestry based bioenergy systems are described and specific indicators are discussed within the bounds of these systems.

Bamboo‐based agroforestry system effects on soil fertility: Ginger performance in the bamboo subcanopy in the Himalayas (India)

An on-farm bamboo intercropping study was conducted near Solan, Himachal Pradesh, India. It uses a split-plot design with two bamboo species (Dendrocalamus asper and Dendrocalamus hamiltonii) and an open field condition as main plots, under which ginger (Zingiber officinale) was grown at five nutrient levels supplied through chemical fertilizers and organic sources (subplots). In the intercropping with bamboo species, ginger yield increased by 10.5-15.6% in comparison to the open field condition. Application of farmyard manure (FYM) based on N equivalent ratio showed the best (P ≤ .05) yield response of ginger (rhizome length, 7.65 cm; yield, 4,028 kg ha −1 ). Photoactive radiation was reduced by 60% under the bamboo canopy. Simultaneously, higher soil moisture (%) content was noticed for D. asper. Various soil physico-chemical properties (top 0-15 cm) were significantly higher in the FYM treatment under D. asper than under D. hamiltonii or sole ginger cropping. Maximum returns (3,595.67 US$ ha −1 yr −1 ) were realized when the ginger crop was raised under the canopy of D. asper and supplied with FYM on N equivalent ratio + plant growth-promoting rhizobacteria. Overall, the results establish that ginger production in the northwest Himalayan region of India is a viable use of land resources for improved economic returns.
