U.S. Precision Ag Trends Variable-rate Technology (VRT) Variable-rate fertilizer and lime (high adoption; >50%) Variable-rate seeding of corn (>25%) Variable-rate seeding of soybeans (quickly growing in adoption) Digital Tools New summary analytics for agronomic and business evaluation (farmer have interests; >10%)
US Technology Adoption
US Technology Adoption
@OhioStatePA Over 60% of Ohio farmers conducting variable-rate P and K. (2017 Ohio Retail Survey**) Over 80% of farmers have a smartphone (2016 Multiple Surveys) Text messaging 85% Emailing 75% Online searches 72% 84% of farmers conducting on-farm research that have adopted precision ag technology & management. (2017 OSU farmer survey on Digital Technologies***) #NutrientIntel
Digital Tech Adoption by US Farmers 92% Sharing Data today o 66% sharing data with 2 or more people o Seed Rep and Agronomic Consultant (>60% sharing with both) 70% have high expectations for their data (2017 USB farmer survey on Digital Technologies)
Guidance and other technology are standard in the cab Smart phones / ipads / Tablets Guidance technology Yield monitors Rate controller (VRT) Planter technology
Planter Technology Precision Planting
In-cab Displays Monitor In-field Performance Improves field execution & on-farm research
In-cab Display Producer Value 1. Identify and correct equipment issues immediately 2. Execute prescriptions; 3. Verification of seed placement 4. Identify soil characteristics (e.g. clods, trafficked areas)

Section / Row Control for Planters Corn - SAVINGS: 4.3% - YIELD: 17% less - HARVET LOSS: >6 times higher Automatic Section Control Technology for Row Crop Planters (Auburn Extension Publication) www.aces.edu/pubs/docs/a/anr-2217/anr-2217.pdf

Active DownForce Technologies Soil physical properties vary spatially indicating planter performance could be improved by adjusting planter settings to field spatial variability. Seeding depth and downforce management are critical for optimization of planter performance (Hanna et al., 2010). Hydraulics provide quicker response and stability. Target Depth (in.) Downforce TRTS AVG Depth (in.) CV Depth (%) 2 none 0 lbs. 1.84 14.5 2 optimal 100 lbs. 2.20 5.1 2 heavy 195 lbs. 2.28 7.8
2 Target with Active DF (100 lbs with active downforce) Uniform Spacing and Emergence 192 bu/ac 2 Target with Mechanical Springs (nominal 125 lbs) Non-Uniform Spacing and Emergence 178 bu/ac
Non-uniform Seeding Depth (without active downforce technology) Seeding Depth CV = 33.5%
FIELD EXECUTION CONSIDERATIONS 2 Fertilizer Sources with 1 Pass MAP Rx --- 0 to 336 kg/ha Potash Rx --- 0 to 336 kg/ha Most companies offer solutions to carry and independently meter 2 or more products on their fertilizer application equipment today (NO need for blending fertilizer sources). #4Rs #NutrientIntel
