  1. 1. Efficient use of compost/farm manure and cost-effective irrigation methods as tools to reduce the degradation of water quality through run-offs from small-scale farms. Samuel Scott, Ph.D.1, George Fitzpatrick, Ph.D.2, and Claire Elliott, BSEE, MBA3 1. Applied Economist, 2. UF-Professor Emeritus and Environmental Horticulturalist, and 3. Business Analyst
  2. 2. Project Summary This project addresses the resource concern of the degradation of water quality via working with seventy-five (75) small farmers in selected counties in Florida . The objectives were to expose these farmers and ranchers to innovative technologies and techniques to: • Reduce farm (nitrate and phosphate) run-offs • Mitigate poorly timed application of pesticides • Improve irrigation methods to enhance smart water application and cost effective irrigation • Efficiently use compost, farm manure, and • Explore the use of solar powered systems for crop irrigation and livestock watering The overall and results are (a) minimized farm land degradation, (b)reduced contamination of associated aquifers, and (c ) increased on-farm productivity and profitability.
  3. 3. Indian River County St. Lucie County Broward County The Zone of Influence included three clusters of producers covering three counties in Treasure Coast and South Florida (Broward, St. Lucie, and Indian River). Producers were exposed to training, technical assistance/outreach and on-farm demonstrations. In addition, a mix-method baseline survey and impact evaluation were implemented using small sample frameworks of farms and farmers from three locations. Project Summary – Project Coverage Area
  4. 4. Project Summary – Implemented in 3 Phases Phase I: Planning, Survey and Data Analysis • Survey and Data Analysis completed before and after implementation Phase III: Training, Outreach, and Technology Transfer • On-farm demonstrations, workshop sessions, and dissemination of technical manuals incorporated into NRCS & private sector tools and materials Phase II: Explore, Design and Demonstrate - Integrated Renewable Energy/Photovoltaics/ Solar Power Sources for Water Harvest from Wells and Open Ditches and Lay Out of low run-off Irrigation Systems (Drip and Micro - How to develop Basic Conservation Plans - How to treat Compost/Farm Manure and Pollutants for Run-Off Mitigation In the model we evaluated water and soil condition use two samples over two periods, the we conducted awareness and practice surveys over the two periods, will conducting training and outreach in basic conservation farming techniques
  5. 5. Activities and Milestones • Training, Outreach, and Technology Transfer through on-farm demonstration, workshop sessions, and dissemination of technical information incorporating into NRCS & private sector tools and information . • Implement the Baseline Survey and Surveys – focusing on awareness and practices • In response to losses due to Hurricane IRMA, we continued assistance to farmers on the Emergency Conservation Program (ECP) with FSA to recover expenses incurred for farm redevelopment and conservation practices. • Completed the retesting of the soil and irrigation water samples from two sites and advised producers in Broward and St. Lucie on soil treatment and fertilizer regime and pesticide usages for various crops. During Hurricane Irma, the Water Management District opened a major canal that flooded the St. Lucie site, which increased the run-off level of surface water. It was observed in the re-testing of the soil, that all the major levels of increased… hardness increased 10 times, calcium increased 10 times, and sodium increased 10 times. Farmers were advised to use fertilizers which would adjust for these micronutrients.
  6. 6. Activities and Milestones Over this project period, the Institute conducted • 16 Grower One-On-One meetings • 30 Field Visits for Group meetings • 49 Technical Assistance and Follow-up • 55 Consultations (in-office and by phone) Conducted solar power consultations: • 4 major group consultations with producers • A Vendor Field Day to evaluate system specification requirements for the demonstration sites. • Field demonstration with groups at farmers • A Regional Symposium and Workshop Demonstration
  7. 7. Project Outcomes and Impacts We examine the outcomes and impacts in the following areas • Performance of the Target Farmers and Results • Water and Soil Result Comparisons per Site • Soil and Organic Matter Management • Water Management and Irrigation Practices • Weed Control and Cover Crops • Environment and Run Off
  8. 8. Project Outcomes and Impacts Performance of the Target Farmers and Results: • 47 Farmers upgraded their Water Harvest System for irrigation • 65 Farmers improved Lay Out of low run-off Irrigation Systems • 7 Farmers improved farm conservation practices • Using plastic mulch and a combination of micro sprinklers and drip irrigation instead of manure and micro sprinkler irrigation and flood irrigation • 65 Farmers improved farm conservation practices • Using a combination of micro sprinklers with manure as mulch to control weeds, improve soils and reduce the frequency of irrigation

  11. 11. Favorable Developments, Challenges and Solutions Farmers are becoming more aware of improved conservation practices • Improved Irrigation Scheduling • Increased use of planting Cold Resistant Crops • Improved use of Soil Amendments – application of lime to impact soil pH • Improvement in Weed Management • Improved knowledge in the use of Cover Crops At the Broward Site farmers continue the excessive use uncomposted manure Costs of the recommended solar power system continues to be high we are now upgrading our in house capabilities to assist with installation
