Blending clover seeds with a starter fertilizer gives the seed an extra boost after germination. According to Penn State University's website, seeding clover in the spring, from April to early May, will yield up to three hay crops for the growing season. Blending fertilizer with the seed also aids in poorly drained soils or when the temperatures remain cool. Cool temperatures may post pone some of the clover seed from rapid germination.
Conduct a soil test of the pasture area. Collect soil from several locations around the field. Mix the soil together. Dry the soil sample. Take the sample to your agricultural extension service. The analysis generally takes three weeks.
Apply the recommended soil amendments based upon the soil test analysis.
Work the soil using a disk cultivator to break up the topsoil and incorporate any recommended soil amendments.
Mix the clover seed and starter fertilizer into the seed broadcaster. Add 10 to 12 lbs. of the clover seed to 1 lb. of the 20-60-20-starter fertilizer per one acre of land. Other fertilizer rates may apply if specified in the soil test analysis.
Broadcast the mixture over the field.
