Progress report for FNC20-1227
In 1989, when I purchased the 26 acres, I planned an apple orchard by converting a 5 acre conventionally farmed field to cover crops. Since then I have used only non-chemical, organic and sustainable practices, i.e. cover cropping, rotations, organic matter, mulching , soil building, pollinator habitats, contour farming, drip-tape irrigation, high tunnels (2), prairie restoration, bird houses, wildlife cover and refuge. Blue Heron Orchard has been continuously certified organic since 2000. In the pasture we did pastured pigs, sheep and lambs, and chickens. We also have about an acre of market garden and a few acres of cool season and warm season pastures that are cut for garden mulch.
My proposal is to harvest on-farm mature eastern cedar trees (Juniperus virginiana) to be used as posts for an eight foot fence to keep deer and raccoons from entering the orchard and eating the apple crop. Deer cause damage to newly planted trees, making it impossible to plant new varieties or replace missing trees. Deer winter-browse the mature tree’s fruiting buds on low branches, often killing the branch which leads to more fruit loss. Eastern cedar trees in proximity to an apple orchard have the ability to infect apple trees with the disease, Cedar Apple Rust/ CAR (Gymnosporangium juniperi-virginianae). A degree-day data field recorder/weather station designed to specifically support the agricultural community will help determine conditions that precede a CAR outbreak in the orchard. Checking the orchard canopy after the possible disease outbreak by leaf symptoms will determine the efficacy of the cultural practices in controlling the disease. Cutting down cedar trees and utilizing the larger cedar trunks for fence posts reduces the possibility of disease vectors that infect apple trees. Energy spent focusing on tree health in the absence of stressing over deer in the orchard and CAR will enhance the orchard's viability to serve a greater community of consumers.
- Create a deer and raccoon exclusion fence around the orchard.
- Monitor animal evidence with a field-style motion camera.
- Track Cedar Apple Rust events utilizing a field monitor designed for determining and recording potential disease outbreak.
- Host an on-farm field day showcasing an holistic approach that includes deer and disease control management options on a certified organic farm.
- Present a report on the project at the February, 2022 Organic Fruit Growers Association (OFGA) Growers Retreat, in conjunction with MOSES Organic Farming Conference poster sessions in La Crosse, WI.
- Write an article for the Organic Fruit Growers publication, "Just Picked," in the fall of 2021 describing the project.
Utilizing Eastern Cedar trees for fence posts grown on-farm saves money for growers and is an allowable option for certified organic production, as opposed to creosote and copper - arsenate treated lumber. Often, more diversified farmsteads with marginal soils are 'infested' with Eastern Red Cedar and have tracts that have been left alone, where tall, straight cedars thrive with few side limbs, creating a perfect post. Activities necessary to carry out the project will include sizing, selecting and harvesting cedar trees for the line, corner and gate posts. Additional preservation of the rot-resistant cedar requires charring the portions of the post that will be in the ground. This process will inhibit soil bacteria from post degradation. Assistants will be hired to manage the preparation, movement and installation of the posts. A Track-Hoe fitted with a Forestry-Mulcher Head will clear the path for the fence and grind all trees and brush into mulch in situ. The farm tractor will be utilized along with hand work to prepare the site line for fence installation. The final step will be to install an eight foot deer fence onto the cedar posts and placing gates at strategic locations (for maintenance facility).
The field day will demonstrate the "charring" of the cedar wood for preservation in-ground. The Field Day Monitor will be demonstrated for the cedar apple rust disease program that tracks the weather conditions and uses a disease model program for determining when a grower takes or decides not to take an action.
