It is extremely level, <br />so no grading is required. The current surface soil material appears <br />adequate to support vegetation, so I do not think additional topsoil <br />will be required. The site to be seeded is basically free of <br />vegetation now, although there is some baltic rush, smooth brome, <br />slender wheatgrass, and quackgrass on the perimeter. Based on <br />surrounding open water, the water table appears to fluctuate within 2 <br />feet of the surface, and to be present year round. You have informed <br />me that there is no supplemental irrigation water available, so I will <br />plan on a dryland seeding. <br />The area appears to be very compacted from vehicle traffic, so I <br />recommend some seedbed preparation. I realize you may have limited <br />equipment, so will give you several options. The optimum would be to <br />plow, then disk at least once, then harrow, and drag. Chiseling could <br />be done instead of plowing. Basically any equipment you have on hand <br />that will loosen the soil at least 8 inches deep and then break the <br />clods up and press it back down into a fairly firm seedbed (you should <br />sink a maximum of 1/2 inch in the soil when walking through it). <br />Drilling would be the best method to seed. I believe the COOP has a <br />drill they rent. If you don't drill, then you will need to broadcast <br />the seed, in which case you need to double the rate (in most cases the <br />extra cost for seed will be more than the cost of renting a drill). <br />If broadcasting, you need to incorporate the seed into the top 1/4 to <br />1/2 inch of soil. This can be done by dragging the surface with old <br />tires, railroad iron, a harrow, etc. _ <br />The exact area is unknown, but appears to <br />recommendation is for one acre, so I will <br />multiply it by the number of acres. With <br />wheatgrass, all the grasses I recommended <br />fill in over time. The best time to do a <br />preferably early July. If you have any q <br />preceding, give me a call. <br />be 3-4 acres. My <br />leave it up to you to <br />the exception of the crested <br />are sod formers that should <br />dryland seeding is July, <br />iestions on any of the <br />Regards, <br />.,C/1~P/» ~/` <br />even L.
