[No. 01]: Sizes and stuff.A regular (US) soccerfield (football field/pitch in the rest of the world) is 100 yards wide and 100-130 yards long, for a maximum area (300 x 390) of 117,000 square feet. An artificial infill soccer pitch/field contains between 200,000-224,000 pounds of crumb rubber. Each square foot of a soccer filed/pitch contains crumb rubber equaling 1.7-1.9 of crumb rubber. The same ought to hold true of a football field. Environment and Human Health, Inc.'s study of artifcial turf infillestimates that a square foot of a field with between two and three inches of in-fill would have between five and seven kilograms of tire crumbs, translating to 11 to 15 pounds. http://www.ehhi.org/reports/turf/turf_report07.pdf (page 16).
