When I design a Multiple Native Species Planting Mixture, (refer to talk given to Range Society under Wildlife-Prairie Buffet) I prefer to use tested, fluffy seed which has a low purity (25 to 65%)...But with a germination or TZ of 65% or better...Seeds such as Big Bluestem, Little Bluestem, Indiangrass, Side-oats Grama, Blue Grama with a lower purity have more crevices, bulk, and inert content to help the small seeds such as sand lovegrass and switchgrass to stay in suspension...AND always keep adding fresh seed mix into the seedbox whenever the agitator shaft becomes visible...
These two practices will produce a more uniformly distributed seedmix and will eliminate the need to use two seed boxes...
