Upcoming Webinars

SA231 - Seed Sampler Lecture and Laboratory

Improve You Understanding of Seed Sampling Methods

Gain knowledge in seed sampling and become an “Authorized Seed Sampler” for ISTA (International Seed Testing Association) Orange Certificates by participating in our NEW 2018 Seed Sampling Webinar Series. This is an educational course targeting seed production or laboratory staff involved in seed sampling who desire a better understanding of principles and concepts.

The course is designed to allow participants to choose their level of achievement.

Option 1 – Learn the basics of seed sampling, sampling intensity, equipment use, and sample submission techniques for collecting samples that are representative of the seed lot and ISTA Orange certificates. There will be four (4) one-hour webinar classes. Participants will be given a Seed Sampling Manual based off the International Rules for Testing Seed.

Join us via webinars on the following mornings from 10:00-11:00 AM Central time zone.


March 7 - Concepts & Definitions of Sampling
March 14 - Sampling Intensity & Practical Examples
March 21 - Demonstration & Discussion of Probes
March 28 - Preparation of Submitted Sample

Option 2- Webinars and complete a written examination to confirm understanding of the requirements of ISTA certification as an “Authorized Seed Sampler”. This would be completed during the month of April at the participant’s location.

Option 3- Webinars, written examination and participate in a Hands-On session to experience seed sampling with different species and containers. Complete a practical examination on May 9th in Brookings SD for becoming an “Authorized Seed Sampler” for ISTA Orange Certificates.

With successful completion of written and practical examinations, the seed sampler will be able to draw samples and submit samples to SoDak Labs for ISTA Orange Certificates as an “Authorized Seed Sampler”.

Course Fee: $250/location (includes sampling manual and two Seed Academy T-shirts); If you desire becoming an Authorized Sampler enroll as an individual. Please register by Thursday, Mar. 1.

SA301 - Seed Biology Course

How do seeds develop and germinate?
What prevents germination during seed dormancy?

Our Seed Biology webinar series is similar to a “300” level University course on Seed Science and Technology presented as twelve (12) one hour webinar classes. The primary references are: “Principles of Seed Science and Technology” and the “Seed Technologist Training Manual”.*

Participants will gain knowledge of seed biology, principles of seed technology and practical experiences relating to seed production and seed quality. This is an educational course for people working in the seed industry who desire a better understanding of principles and concepts. This is a great course for persons planning to become a Registered or Certified Seed Technologist.
