Field capacity: The maximum volume of moisture a soil can hold after drainage has occurred, An expression of the water-hotting capacity and moisture status of soils. Hand excavation: Manual sod excavation via the use of hand tools only. Use of hand toots for initial excavation should be avoided. Hand tools shall not be used in a manner that results in breakage of roots,bark penetration or separation of bark from roots. Hand tool use should be limited to small tools(e.g..spade,trowel)for minor excavations or in restricted spaces. Pte.mattocks.digging bars or similar implements requiring striking the earth shat}not be used for excavation, Hand shovels may be used for minor excavations.or where access is limited for vacuum equipment,or hydraudc slurry cannot be Rushed out of the excavation. Such usage shall not result in breakage of roots.bark penetration or separation of bark from roots. Hydraulic excavation: Soil excavation performed using pressurized,focused water via 1)pressure washer,portable fire pump.or similar equipment or 2)hydraulic truck-mounted equipment(Hydra-vac). Equipment should be used et the minimum pressure required to remove the soil from around roots and out of the resulting excavation void,without causing breakage of roots,bark penetration or separation of bark from roots. N Pneumatic excavation: Sod excavation performed via supersonic compressed air excavation with a tool called an air spade. This tool removes soil from roots(or pipes.wires,etc,)with little or no damage to the roots(or utilities). Soil is separated and blown away via highly focused.supersonic velocity compressed air,which separates the soil particles without penetrating roots. Cabling&Bracing: The installation of hardware in and/or about trees for the purpose of providing supplemental support of weak, defective or otherwise suspect limbs and/or stems;supporting of newly planted trees;bracing cracks;propping trees or tirrdhs,or otherwise providing support. The installation of cables,bolts and other hardware in trees is intended to reduce the potential for failure (breakag&uprooling)• Such bracing does not permanently remedy structural weaknesses,and is not a guarantee against failure. The trees and hardware must be inspected periodically for hardware deterioration,adequacy and changes in the tree's and see condition. Pruning standards: The following standards were developed by a consensus of representatives from various industry professional organizations; 4.American National Standards Institute,2008.Standard Practices for Tree.Shrub end other Moody Plant Maintenance (Pruning),American National Standards Institute(ANSI A300 Pad 1-2008) ♦ International Society of Arboriculture,2002. Best o Management Practices. Tree Priming.International Society of Avboricultwe 4 Current industry standards: The most current and applicable publications of 1)Beat Management PracOcss,International Society of Arboriculture;2)American National Standards Institute,A300 and 2133(all parts).
