Major Benefit #6 - MRBs® protect the seed from dessication.
MRB Benefit 6
Virtually all fertilizers are a form of salt, which has a strong affinity to water. If placed in too great of a concentration too close to the seed, it will draw moisture away from the seed & surrounding soil. MRBs® place these fertilizers at an ideal location – far enough to prevent desiccation even in dry conditions, but close enough to be easily accessed by the plants after conversion.
