/.'~. Domtar Gypsum Inc. 1191A Dr. Jim Feucht will be responding to this soil test report as it relates to the growing of various woody plant material. These recommendations are for the grasses which you are going to be growing. This is a very infertile soil. The nitrogen, phosphorus, potassium, and iron levels are quite low for growing grasses. As a preplant application, you may want to deeply incorporate approximately 15 lbs. per 1,000 sq. ft. of triple superphosphate along with about 5 lbs. per 1,000 sq. ft. of muriate of potash. These fertilizer should be rototilled or disked in quite well before seeding the site. Then, as a surface applied starter fertilizer, you would want to use something with a ratio of something like a 1:2:1 of N to PzOs to KzO. Fertilizer with an analysis such as 10-20-10 used to supply about 1 lb. of actual nitrogen per 1,000 sq. ft. (this would take 10 lbs. of a 10-20-10 per 1,000 sq. ft.) surface applied, and then harrowed, matted, or otherwise gotten lightly into the soil ahead of seeding should be suitable for establishment. This type of fertilizer application along with irrigation for establishment would tend to help grow more vigorous plants. Then, no doubt, for the next two or three years, at least, you will want to make fertilizer applications, probably in the spring and fall, when the weather is cool, to this grass. Use of a ratio of something like a 1:1:1 of N:PzOs:KzO analysis fertilizer should be sufficient. ' An analysis such as 10-10-10 or 15-15-15 should work quite well as a maintenance fertilizer on this site. The iron level is very low for many grasses. You may need to, after the grass is up and growing well, apply supplemental iron. Iron fertilizer may be required for normal growth. The salt level is moderately high. This can cause a problem in growing certain grasses. However, with irrigation and management, likely the salt levels will diminish. Also, the broad base grass mix should contain some grasses that would be expected to grow suitably at this salt level. The copper, boron, and manganese levels ere lower than we frequently see; consequently, problems with these elements would not likely be of much importance. The SAR indicates that sodium should not be a problem on this soil. Generally, the amount of moisture that a new planting gets is as critical as anything in getting good stands established. Consequently, you will need to manage water as well as possible, at least initially, to get a good stand. After the grass is established, then, of course, the amount of water can be cut back.
