North Central SARE Ag Innovations
On-Farm Fertigation Trials in Kansas City-Area Organic High Tunnels
Farmer and Rancher Innovations
Five certified organic farms in the Kansas City area did one-year comparisons of the use of compost, fertigation and foliar feeding on high tunnel tomatoes, with respect to quantity and quality of yields. The fertilization treatments they tested included foliar feeding and fertigation with fish emulsion, and chicken-litter compost. Each farm developed its own comparison, as opposed to a single experiment replicated on all five farms. The farmers involved in this project gained general impressions about the potential usefulness of fertigation and/or foliar feeding, but no conclusive results were derived. They also discovered the difficulty of coordinating a multi-farm project without dedicated, experienced leadership.
The Kansas City area is in USDA Plant Hardiness Zones 5b and 6a.
About this series: Farmer and Rancher Innovations, part of the Ag Innovations series, capture the lessons learned from SARE-funded trials and demonstrations conducted primarily by farmers and ranchers.
