Get ready to learn more about agronomy, ag technology, crops, plant and soil science, weeds and pests!
What can you do?
In the plant science project, you can:
- Explore ag technology and how it has improved farming practices, changed farming, improved farmers' resources, etc.
- Investigate how cross-pollination works.
- Discover how plants are used other than for food.
- Learn about the impacts certain weeds and pests can have on the farming industry.
These are just some of the many ways you can participate in this project.

Crop Scouting
In this activity, teams of youth compete on their ability to assess crops for outcomes and risks like weeds and pests.
Teams can be only 4-H or FFA, 4-H and FFA mixed, and/or multiple clubs or counties.
- Junior division - Individuals in grades 3-5.
- Intermediate team - A team of 3-5 youth in grades 6-8.
- Senior team - A team of 3-5 youth in grade 9 and above.
4-H Agriculture Ambassadors
This opportunity is for youth in grades 10 -12. The 4-H agriculture ambassadors are a voice for youth in agriculture and 4-H.
Youth serve Oct. 1 - Sept. 30; applications open August of the current year for the following 4-H year.
4-H Agronomy Days
Experience a college classroom! Explore a college and learn from a faculty member. There will be time in the day for tours and asking all your questions about classes and college majors. This is a great way for you to learn more about the study of agronomy and college life.
4-H Agronomy Tours
If you are interested in agronomy and horticulture, you could do them as a career. Attending a 4-H agronomy tour at an ethanol plant, large-scale dairy operation or seed plant will give you an idea of jobs for you in the future.
