Module 1   Overview Of Agroforestry  Powerpoint Presentation Module 1 Overview Of Agroforestry Powerpoint Presentation Presentation Transcript

  • Agroforestry Training for Natural Resource Professionals in Minnesota Diomy S. Zamora Extension Educator University of Minnesota Extension
  • Overview of Agroforestry Practices
  • Motivated by: Economic decline of rural America Need for crop diversification Need for alternatives to industrial agriculture Concerns about soil erosion and environmental pollution Need to restore wildlife habitat
  • Definition and Practices Agroforestry is intensive land-use management that optimizes the benefits (physical, biological, ecological, economic, social) from biophysical interactions created when trees and/or shrubs are deliberately combined with crops and/or livestock
  • Is it Agroforestry Four defining criteria provide the key •Intentional •Intensive •Integrated •interactive
  • Intentional Combinations of trees, crops, and/or livestock are intentionally designed, established, and/or managed to work together and yield multiple products and benefits, rather than as individual elements which may occur together but are managed separately Intensive Agroforestry practices are created and intensively managed to maintain their productive and protective functions, and often involve cultural operations such as cultivation, fertilization, irrigation, pruning and thinning
  • Integrated Components are combined into a single, integrated management unit. Integration may be horizontal or vertical, and above- or below-ground, uses more of the productive capacity of the land and helps to balance economic production with resource conservation Interactive Agroforestry actively manipulates and utilizes the interactions among components to yield multiple harvestable products, while concurrently providing numerous conservation and ecological benefits
  • Agroforestry practices are designed to fit specific niches within the farm to meet specific landowner objectives

  • Five recognized agroforestry practices Riparian Forest Buffers Windbreaks Alley Cropping Silvopasture Forest Farming
  • …an area of trees, shrubs, grasses and forbs, adjacent to a streams or creeks, which is managed…. “Living Filters”
  • Windbreak / Shelterbelt / Timberbelt Definition Plantings of single or multiple rows of trees or shrubs that are established for one or more environmental purposes. Timberbelts add an economic product from the linear tree rows.
  • Alley Cropping Combines trees planted in single or grouped rows with agricultural or horticultural crops cultivated in the wide alleys between the tree rows. High-value hardwoods, e.g., oak, walnut, ash, and pecan are favored species and may provide high-value lumber. Crops grown in the alleys, and nuts from walnut and pecan trees, provide annual income from the land while the longer-term wood crop matures. Specialty crops (herbs, fruits, vegetables, nursery stock, flowers, etc) grown in alleys, microclimate created by trees boosts economic production of sensitive high-value crops
  • Alley Cropping
  • Silvopasture Practice combines trees with forage (pasture or hay) and livestock production. Established by adding trees to existing pasture, or by thinning an existing forest stand and adding (or improving) a forage component. Trees are managed for high-value sawlogs, provide shelter for livestock, protecting against temperature stresses. Forage and livestock provide short-term income while sawlogs are being grown, providing diversified economic returns.
  • Silvopasture
  • Forest Farming High-value specialty crops are cultivated under the protection of a forest overstory that has been modified and managed to provide the appropriate microclimate conditions. Shade-tolerant specialty crops like ginseng, shiitake mushrooms, and decorative ferns grown in the understory are sold for medicinal/botanical, decorative/handicraft, or food products. Overstory trees are managed to produce high-value timber or veneer logs.
