AI summary
The present disclosure relates in general to the imbibition of grains for the agronomic, horticulture, animal feed, and malting industries. More specifically, the present disclosure relates to systems and methods for improving germination and plant seedling development rates using low volts of direct current to increase the productivity, efficiency, and economics of industries that rely on grain germination and seedling development to produce a product. The application of less than or equal to approximately 36.0 volts of direct current to grains in aqueous solutions for at least approximately thirty minutes has been found to significantly improve coleoptile length, radicle length, invitro neutral detergent fiber digestibility, germination percentage, glucose concentration, and amino acid concentration on a dry matter basis.
