In April, 2023, Tom Johnson of Kamprath Seed Co. joined me for a field day showing the results of different kinds of cover crop that we had planted in a walnut orchard the previous November. He describes the characteristics and uses of grasses, mustards, and legumes as cover crops in the context of their performance in the trial. The cover crops we tried were a winter triticale, the seeds for bees mustard pollinator mix, and the Kamprath Seeds walnut mix, a blend of legumes, mustards, and grasses.
