z The seed mixture should not include sandsage. How- ever, we recommend that sandsage inflorescences be har- vested at seed-ripe time and broadcast along lines ori- ented from southwest to northeast and spaced about 50 feet apart. However, since it is apparent that herbi- cides will have to be used for control of broadleaf annuals during grass seedling establishment, seeding of the sandsage should be in late fall after grass establish- ment. Seeding and Mulching We recommend seeding in mid-May and then mulching with manure at about 30 tons per acre dry weight. How- ever, it is recognized that the sand topsoil placed at times other than this optimum seeding time will have to be stabilized. An approach is to spread the manure immediately after topsoil placement, then to drill seed into and through the manure mulch in mid-May. This technique will probably result in a less uniform stand than obtained by seeding and then mulching. However, with timely irrigation it should be possible to esta- bligh a satisfactory stand. With the 30 ton/acre rate of manure no commercial fertilizer should be needed. Drilling will require use of a drill adapated to feed ~ light chaffy seed and to control depth of seed place- ment (about ~") in the sand. Sewage sludge could be used to supply N and P to the seeding. However, sewage sludge would not be nearly as effective as manure as a surface mulch to control wind erosion. Irrigation Begin sprinkler irrigation immediately after seeding and continue applying about 0.25 inch daily for two to three weeks for germination and emergence. Then irriga- tion can be suspended for about three weeks, but one must watch the condition of seedlings to detect advancing drought or damage by rabbits and insects. When the seedlings are about three weeks old, one should sprinkle daily for three or four days to promote the growth of adventitious roots. During the next six to eight weeks, water weekly as needed. Then water daily once again for three or four days to promote adventitious roots. Continue watering bi-weekly in late summer. Irrigation would require a total application of about 9 inches of water to the soil surface. Assuming sprinkler irrigation is 708 efficient ~ this would require a total of 13 inches of water or slightly over 1 acre foot per acre to be revegetated.
