Today we go back to the beginning of any soil health program - or any crop for that matter - seed. We are joined by Steve Zwinger who is an agronomist at NDSU\u2019s Carrington Research Extension Center and Jason Goltz the Regulatory Manager for the North Dakota State Seed Department. Together we will explore and discover the value of seed selection and how seed labels need to be evaluated prior to making any purchases.

Steve shares that, unlike other crops, cover crop success is not tied to a high grain yield. The focus for cover crops is a quick rate of maturity resulting in putting on biomass and providing shade. Cover crops are used to augment control of erosion and weed growth. The quicker it can get to maturity the quicker it can perform its roll in the soil.

\u201cRye has been determined to be one of the number one cover crops used by farmers across the country\u2026.So one of the things I felt strongly about was the fact that we needed some pedigree or known variety, identity preserved seed out there.\u201d - Steve Zwinger

Steve is an advocate for certified or registered seed. Added regulation provides a standard of \u201chigher quality seed such as germination, seedling vigor, and purity in terms of weed seeds and other things.\u201d Having an identified variety will lead to better variety selection for example farmers in the north need to prioritize winter survivability in making their selection. Any number of goals could be focused on by the farmer to tailor the effect of the cover crop to the field it is planted in.

Steve\u2019s seed breeding work revolves around blending where varieties are blended together. He takes advantage of rye\u2019s ability to be \u201cconstantly changing itself and adapting itself to the environment.\u201d While Steve focuses on creating and certifying the variety seed purchased, Jason shares the requirements and regulations in seed..

"If it's going to be planted, it's a seed in state and federal law. Both say that all seed has to be labeled." - Jason Goltz

Just because a crop is not harvested as in the case of the cover crops, does not mean it does not need to be clearly labeled. These labels should identify the type of seed, the quality of the seed and the amount and type of weeds potentially present. Also of great importance, seed has to be labeled for the state it is sold in to comply with local state laws. The significance of this is to avoid transmission of a prohibited noxious weed that may not be illegal in a different state.

\u201cVariety evaluation and development is a very important aspect in agriculture because it's probably the easiest decision a farmer can make before he enters the field that will have the largest impact on their production.\u201d - Steve Zwinger
