Mixed species plantations: prospects and challenges
7 About 2% of English-language literature on plantations deals with mixed-species 8 plantations, but only a tiny proportion (<0.1%) of industrial plantations are 9 polycultures. Small landholders are more innovative, with 12% of Australia’s farm 10 forestry plantations under mixed-species plantings, and 80% of Queensland’s farm 11 forestry as polycultures. We examine reasons for this discrepanc...
متن کاملComparing productivity of pure and mixed Douglas-fir and western hemlock plantations in the Pacific Northwest
We studied pure and 50/50 mixtures of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and western hemlock (Tsuga heterophylla (Raf.) Sarg.) plantations to compare attained total yields between mixed-species stands as opposed to monocultures of equal densities. Whether overall stand density influences this outcome has not been adequately investigated, and to address this we included three den...
متن کاملEfficiency of superabsorbents in improving water productivity
Agricultural residues and various other materials are currently being used as additives to improve the physical and chemical properties of soil. Iran is located in an arid and semiarid region, so using strategies to reduce water use will reduce the problem water scarcity. The use of superabsorbent to increase water uptake and retention is one of the solutions that have been applied to improve w...
متن کاملAssessing nitrogen fixation in mixed- and single-species plantations of Eucalyptus globulus and Acacia mearnsii.
Mixtures of Eucalyptus globulus Labill. and Acacia mearnsii de Wildeman are twice as productive as E. globulus monocultures growing on the same site in East Gippsland, Victoria, Australia, possibly because of increased nitrogen (N) availability owing to N(2) fixation by A. mearnsii. To investigate whether N(2) fixation by A. mearnsii could account for the mixed-species growth responses, we asse...
متن کاملProductivity, nutrient cycling, and succession in single- and mixed-species plantations of Casuarina equisetifolia, Eucalyptus robusta, and Leucaena leucocephala in Puerto Rico
Tree growth, biomass productivity, litterfall mass and nutrient content, changes in soil chemical properties and understory forest succession were evaluated over a 8.5-year period in singleand mixed-species (50 : 50) plantations of two N2-®xing species, Casuarina equisetifolia and Leucaena leucocephala, and a non-®xing species, Eucalyptus robusta. At the optimal harvest age for maximum biomass ...
