  1. Precision Ag in Horticulture Crops Mattie Crownover

  2. Objectives • Is it cost effective • Is it environmentally responsible

  3. Problems • Little research has been done • Small farms • Crops are cared for and harvested by hand

  4. Harvest method (%)Mechanically Roots, tubers, & bulb Carrot 2 98 Potato 2 98 Onions 98 2 Fruiting Vegetables Peppers - bell & chili 80 20 Tomato 100 0 Melon/vine crops 100 0 Berries 60 40 Leafy veggies and greens Lettuce 100 2  Spinach 2 98

  5. The need of Precision Ag • High per acre crop values • Need for greater yield • Lack of help

  6. Benefits • Increases yield • Improves product quality • Efficiency of crop chemical use • Conserve energy • Product Efficiency

  7. Areas of Precision Ag • Site-Specific Management • Postharvest Process Management

  8. Yield monitors Present technology is in the mass flow or mass accumulation categories. • Used where the crop harvested is conveyed on a belt or chain. Load sensors are placed on the idler wheels supporting the belt. Continues weight sampling is combined with GPS. • Load cells are under a hopper or wagon monitoring the weight of the crop. Combining weight changes in the hopper per unit times with the GPS time and position.

  9. Yield Monitoring Handheld GPS receivers & Hand-Trak • Not as accurate, but offer a means for the grower • Improvements in progress

  10. Other Areas of Adoption • Citrus crops in Florida • Working on keeping water and nutrients • in the root zone. • Commercial Blueberry fields • Real-time Slope mapping • Viticulture • Remote sensing from satellite and airborne platforms provides images depicting vineyard conditions.

  11. Nitrogen Sensing • Chlorophyll Meter • Dualex Measures polyphenic compounds that accumulate in the epidermis of leaves under N stress.
