425   When growth begins in the spring, broadcast 3 lbs triple superphosphate (0-46-0) and 6 lbs 15-0-15 or equivalent fertilizer per 1,000 square feet.  In July, broadcast 6 lbs 16-4-8 or equivalent fertilizer per 1,000 square feet.  (Recommendations when phosphorus and potassium soil tests are L-L, L-M, L-S, M-L, M-M, M-S)

426   When growth begins in the spring, broadcast 3 lbs triple superphosphate (0-46-0) and 3 lbs 34-0-0 per 1,000 square feet.  In July, broadcast 3 lbs 34-0-0 per 1,000 square feet.  (Recommendation when phosphorus and potassium soil tests are L-H, L-EX, M-H, M-EX)

427   When growth begins in the spring, broadcast 6 lbs 15-0-15 or equivalent fertilizer per 1,000 square feet.  In July, broadcast 6 lbs 16-4-8 or equivalent fertilizer per 1,000 square feet.  (Recommendation when phosphorus and potassium soil tests are S-L, S-M, S-S, H-L, H-M, H-S, EX-L, EX-M, EX-S)

428   When growth begins in the spring, broadcast 3 lbs 34-0-0 per 1,000 square feet.  In July, broadcast 3 lbs 34-0-0 per 1,000 square feet.  (Recommendation when phosphorus and potassium soil tests are S-H, S-EX, H-H, H-EX, EX-H, EX-EX)

429      The extent of growth can be controlled by the amount of nitrogen fertilizer applied, low maintenance at a rate between 1 to 2 lbs nitrogen per 1,000 square feet per year, high maintenance, between 3 to 5 lbs nitrogen per 1,000 square feet per year.  If the grass clippings are removed, the amount of fertilizer applied should be increased by 25% and the turf soil tested every other fall to determine what levels of phosphate and/or potash will be needed to sustain vigorous growth.

535   Broadcast dolomitic limestone as recommended, either in the fall or early spring.
