A wet soil tends to <br />deform rather than shatter when decompacted which does not reduce compaction levels and can in fact <br />increase compaction and root limitations. Decompaction should be done as soon as possible at the site to allow <br />time for water to percolate through the soil and move salts to deeper depths. <br />i <br />Once the site has been ripped and the site should be seeded to a moderately tolerant saline seed mixture. A <br />proposed seed mixture can be found in Table 1. The seed mixture in Table 1 is based on saline tolerance of the <br />proposed species, identified grass species on the site, previous seeded plants and professional experience. It <br />may be necessary to change some recommended species due to seed availability. Seeding should be conducted <br />once soil temperatures have decreased to below 45 degrees Fahrenheit. The entire site should be mulched with <br />2 to 3 tons per acre of straw. The main purpose of the straw mulch is to provide carbon to reduce the quantity <br />of plant available nitrogen in i he system. By removing the plant available nitrogen weed pressure should be <br />decreased for the newly planted reclamation grasses next spring. <br />It may be necessary to spray the site to help suppress some of the annual weeds this fall. If required it is <br />recommended that the site b` sprayed around the beginning of September with a good broad spectrum <br />herbicide. If sprayed at this time there should be adequate time for the plants to uptake and translocate the <br />herbicide to their roots. Spraying in the fall is a very effective control for tough to control perennial weeds such <br />as bindweed. j <br />Table 1.
