Abstract: Experimental Project 834 (contract with W. Carr) includes four studies concerned with the rehabilitation of severely disturbed forest lands. The objective of one of these studies (E.P. 834.02) was to modify existing fire fighting equipment for use in hydraulic seeding (hydroseeding). Hydraulic seeding is a method of revegetation in which seed is applied in a water slurry. The slurry may contain fertilizer, mulch, and/or a chemical soil stabilizer. Agitation of the slurry in a holding tank is necessary to assure homogeneity. Conair Aviation Ltd. has constructed a ground-based fire retardant spreader for the Ministry of Forests, Protection Branch. Since this unit has an agitation system, it was chosen for modification. The result has been a complete redesign of the existing retardant spreader. Randy Lafferty and Nick Perkins of Conair assisted in redesigning the retardant spreader and supervised SUbsequent construction under contract with the Research Branch. The specifications for the hydraulic seeder portion of the unit were provided by the Research Branch, while the Protection Branch'was responsible for the fire fighting requirements. The new slurry applicator has 2275 liter capacity and two pumping systems, a volume pump and a pressure pump. The engine is a 7.83 kW Wisconsin EY-44W with electric start. All hoses and fittings meet standard forestry specifications. This new slurry applicator has a range of uses in the forest environment. Application of fire retardant, herbicides, and pesticides is accomplished by use of the pressure pump, .with a nozzle pressure of 3.45 MPa. The volume pump can be used for tank filling, standard fire fighting, and hydraulic seeding. The volume pump maintains a 0.345 MPa nozzle pressure, and is also responsible for the hydraulic agitation of the slurry. The Research Branch plans to use this slurry applicator for establishing demonstration and research areas of hydraulic seeding in all Regions. This will be in conjunction with general erosion control training seminars. When fire hazard is high, the slurry applicator may be loaned to the Protection Branch if required. For further information write to the Research Branch, Ministry of Forests, Parliament Buildings, Victoria, B.C. V8W 3E7. [Abstract contains full text of memo.]
