118   Two cups (1 pint) fertilizer is equal to approximately 1 pound.  Three-quarter pint limestone weights approximately 1 pound.

300   As a precaution against fertilizer burn, water the plants immediately after the fertilizer is applied.

301   Broadcast 1-1/2 cups triple superphosphate (0-46-0) and 2 cups 15-0-15 or equivalent fertilizer per 100 square feet in early spring and then in early summer, broadcast either 2 cups 12-6-6 or 11-7-7 or equivalent fertilizer per 100 square feet.  See below for application instructions.  (Recommendation when phosphorus and potassium soil tests are L-L, L-M, L-S, M-L, M-M, M-S)

302   Broadcast 1-1/2 cups triple superphosphate (0-46-0) and either 2 cups calcium nitrate (15.5-0-0) or 1 cup 34-0-0 per 100 square feet in early spring and then in early summer, broadcast either 2 cups calcium nitrate (15.5-0-0) or 1 cup 34-0-0 per 100 square feet in early summer.  See below for application instructions. (Recommendation when phosphorus and potassium soil tests are L-H, L-EX, M-H, M-EX)

303      Broadcast 2 cups 15-0-15 or equivalent fertilizer per 100 square feet in early spring and then repeat in early summer.  See below for application instructions.  (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) 

304   Broadcast either 2 cups calcium nitrate (15.5-0-0) or 1 cup 34-0-0 per 100 square feet in early spring and repeat in early summer.  (However, if pH is greater than 7.0, use 1 ½ cups ammonium sulfate instead per 100 square feet and repeat in early summer.)  See below for application instructions.  (Recommendation when phosphorus and potassium soil tests are S-H, S-EX, H-H, H-EX, EX-H, EX-EX)

306   Uniformly spread fertilizer over the area.  Not necessary to remove the mulch before applying the fertilizer.  Brush or rinse the fertilizer from the leaves and stems.

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