Power of Agriculture Lecture Series 


What is sustainable agriculture? It seems like all you hear about today is "going green". How does one go green and how can you empower yourself through agriculture. This semester-long series of events fosters openness, curiosity and dialogue about sustainable issues and topics in your community, country and world. Events will take place at the Donald F. Harris r. AgriScience & Technology Center (Bloomfield High School) and Granby Memorial High School. We challenge you to experience the "Power of Agriculture".



Aquaculture & Hydroponics


Planning for the AgriScience Spring Open House is well under way with over 600 heads of tilapia and catfish snuggled beneath lettuce and basil. Though currently in seedling form, February will be blooming' with fresh greens a part of the district Farm to School imitative. Featured magazine gets the exclusive.

Ag-Science Students Climb Mt. Everest!


The second annual trip to the highest summit in Connecticut, Bear Mountain located in Salisbury, CT, offered some spectacular views of the state and nearby Massachusetts. Starting out on the blue blazed Undermountain trail which eventually led us to the summit via the white blazed Appalachian Trail students from the environmental science class had a opportunity to investigate invasive plants and become proficient with map and compass use.          


Fall Project Oceanology Overnight Trip


First year AgriStudents complete a rite of passage with the annual Project Oceanology overnight excursion. 26 students enjoyed a two day one night educational experience in fish respiration, saltwater chemistry, and a fish harvest complete with blue crabs and flounder.

Detail of Vegetation Analysis


A plotless sampling method, called point-quarter sampling, is useful for sampling plants and other non-motile organisms. It is easy to use in the field and is ideal for sampling using teams of 3-4 students. Like plot sampling, point-quarter sampling can yield data that can be used to generate a variety of quantitative results, including importance values and several diversity indices.


Using the point-quarter sampling technique, you will find the species, point-to-plant distance, and the diameter at breast height (DBH) for the trees at each point along a defined transect. These data can be used to calculate, for a much larger area than you sampled, and importance value (IV) for each of your tree species. The IV for a species is:



Relative Frequency + Relative Density + Relative Coverage




IV = RF + RD + RC
