Project Information

Summary:

PROJECT BACKGROUND
We have a 13 acre farm, 10 acres tilled. For the last 22 years we have been incorporating vegetables and herbs into old wheat ground.

Poultry has long been a part of the farm, but until the grant had not been utilized in a sustainable manner. We had been good at crop rotation, but not at incorporating poultry and fallow into the mix.

PROJECT DESCRIPTION
GOALS:
• Reducing fuel cost and consumption in greenhouse used to grow herb and tomato transplants
• Managing soil quality in a chemical free system
• Controlling insects in a chemical free system

PROCESS
We incorporated a 6 plot rotational system, with rotations of herbs, vegetables, chickens and fallow, in various combinations of plastic covered, insect fabric, row covered and uncovered high and low tunnels. Chickens were used both as a means of heat, fertilization, and insect and ground maintenance.

The one epic fail was the nearly complete collapse of one tunnel during a heavy snow. None of the tunnels containing poultry ever gathered snow on the roofs due to the poultry heat. Only twice in two years did the water ever freeze over.

The one challenge that was anticipated were the chickens’ tendency to “home”. This was reasonably alleviated by making their night quarters mobile, so that when they were relocated, they still identified with the House. The most surprising and unexpected result was a hatching by one young hen, who set a nest in the previous quarters, and hatched a remarkable 13 chicks in the high tunnel. She kept them all, and we lost no birds to predators in the high tunnels.

PEOPLE
• Sanjun Gu- Instructor Lincoln University of Jefferson City, MO, High Tunnel Classes
• Rebecca McMahon- Horticulture Agent, Sedgwick County Extension, support and horticulture questions.

RESULTS
• Soil was initially damaged and generally unproductive. The first year after running poultry in Tunnel 1 generated 50 percent higher yields, planting in lettuce, Swiss Chard, and okra. Six month break down showed no significant change in acidic value, but definite growth in Nitrogen in both tunnel 1, tunnel 2 and plot 1 after the first year.
• Straw and wood chips were used as weed barrier and row cover. With the poultry clearing past plant material, the organic matter was higher at the 18 month test.
• Insect prevention was significant as to grasshopper deterrence. Other pests seemed more controlled with row cover. A difficult process to measure; the fact that we produced squash was a great tip off.
• The heat management of the tunnels was the greatest success. Tunnel 3 is used for transplants and the brooder bench kept the tunnel from freezing at all times. The heat from the chicks proved sufficient to maintain the health of the tomato transplants without additional heat in the high tunnel.

DISCUSSION/ WHAT WAS LEARNED/RECOMMENDATIONS
• Becoming more proactive rather than reactive when it comes to farm planning.
• Addressing potential problems before they arise.
• Being flexible with a plan when one avenue does not work as planned.
• Many farmers have asked about our project. We love to share the results of the past two years, trying to present the realistic problems as well as successes.
• A supportive family cannot be substituted. With every facet of the project, something needed to be built, designed, tweaked, loaded and moved. We paid for very little in the way of labor. I might rethink that were I to do another project.
