Section A.

Establishment: Apply 25 lbs. of 6-12-12 at seeding only, or 13 lbs of 8-8-8 or 10 lbs. of 10- 10-10 or 7.0 lbs. of 15-15-15 per 1000 sq. ft. at seeding and again six weeks later if seeded before 15 in the fall or Mar.1 in the spring. Fall establishment is preferable. A slow release (60 day) form of nitrogen may give best results. Select an appropriate maintenance schedule (see section B below) and begin following that schedule the very next spring or fall season after lawn establishment, until you soil test again.

Section B.

Maintenance of Established Lawns: Choose one level of maintenance to follow. The lowest maintenance level will require less frequent mowing but may be more weedy and not always maintain the quality of lawn desired. Your soil P and/or K levels are low to medium. These fertilizer maintenance levels should, over time, build your soil out of the low testing range for P and K. However, if grass clippings are continually removed, K levels may stay in the low or medium testing range. This is normal, but increases the importance of not missing any of the fall maintenance applications.

I. Highest Level Maintenance of an established lawn (Availability and Proper Use of Irrigation is preferred when using this maintenance level): (1) Topdress annually Sept. 1 and Oct. 15 and Nov. 15 with 13 lbs of 8-8-8 or 10 lbs. of 10-10-10 or 7.0 lbs. of 15-15-15 per 1000 sq. ft. (2) Topdress annually Mar. 15 and Apr. 15 with 3.1 lbs of 16-4-8 or 1.75 lbs. of 34-0-0 or 28-3-3 or 29-3-4 or 28-4- 6 or other fertilizer material of a similar ratio (very low P and K content) per 1000 sq. ft. If the fertilizer material contains at least 30 percent of a slow release (60 day) form of nitrogen, then the Sept. and Oct. applications may be combined and spread as one application in Sept. and the Mar. and Apr. applications may be combined and spread as one application in Mar. Follow this schedule for 2 growing seasons, then soil test again.

II. Medium Level Maintenance of an established lawn: Topdress annually Sept. 1 and Oct. 15 and Mar 15 with 13 lbs of 8-8-8 or 10 of 10-10-10 or 7.0 lbs. of 15-15-15 per 1000 sq. ft. If the fertilizer material contains at least 30 percent of a slow release (60 day) form of nitrogen then the Sept. and Oct. applications may be combined and spread as one application in Sept. Follow this schedule for 3 growing seasons, then soil test again

III. Lowest Level Maintenance of an established lawn: Topdress annually Sept. 1 and Mar 1 with 13 lbs of 8-8-8 or 10 of 10-10-10 or 7.0 lbs. of 15-15-15 per 1000 sq. ft. A fertilizer containing at least 30 percent of a slow release (60 day) form of nitrogen may give the best results. Follow this schedule for 4 growing seasons, then soil test again.
