Comparison of OptRx and farmer flat rate
2008 Field Testing
Flat rate = 50 Lbs of N/ac
OptRx prescribedpasses
Flat rate = 50 Lbs of N/ac
OptRx prescribed rate and farmer’s flat rate alternated across entire field
• $.60 per lb N and $4 per bushel corn• Crop sensor rate and farmer’s flat rate alternated across entire field• Iowa
– Field 1 - $41.00/ac more than flat rate– Field 2 - $24.00/ac more than flat rate– Field 3 - $100.00/ac more than flat rate
• Missouri– Field 1 - $75.00/ac more than flat rate– Field 2 - $120.00/ac more than flat rate– Field 3 - $15.00/ac more than flat rate
Crop Sensor vs. Flat N Rate - 2008
• $.50 per lb N and $3.50 per bushel corn• Crop sensor rate and farmer’s flat rate alternated across entire field• Iowa
– Field 1 $21.96/ac more than flat rate– Field 2 $47.38/ac more than flat rate– Field 3 $62.82/ac more than flat rate– Field 4 ($1.09)/ac less than flat rate– Field 5 $15.03/ac more than flat rate
Crop Sensor vs. Flat N Rate - 2009
• Missouri
– Field 1 $14.09/ac more than flat rate– Field 2 $4.41/ac more than flat rate– Field 3 $7.09/ac more than flat rate– Field 4 $11.32/ac more than flat rate– Field 5 $26.78/ac more than flat rate– Field 6 $33.03/ac more than flat rate– Field 7 $35.27/ac more than flat rate– Field 8 $3.81/ac more than flat rate– Field 9 $2.70/ac more than flat rate– Field 10 $25.89/ac more than flat rate– Field 11 $41.69/ac more than flat rate
Crop Sensor vs. Flat N Rate - 2009
• Missouri
– Field 12 $22.19/ac more than flat rate– Field 13 $33.54/ac more than flat rate– Field 14 $45.00/ac more than flat rate
• Kansas– Field 1 $11.82/ac more than flat rate
• Louisiana – Field 1 $2.68/ac more than flat rate
Crop Sensor vs. Flat N Rate - 2009
List Pricing• $3000 per sensor• $1500 per master module (1 per system)• Recommend 5 sensors for 80 foot or wider boom• Recommend 3 sensors for less than 80 foot swaths
Obstacles (corn market)
• Corn farmers generally don’t believe there is anything wrong with their current flat rate N program. – Must prove sensors are better than their current N program– 2 years of good results before they start to trust it
• Application timeframe– Limited timeframe with toolbar because corn must be at V4/V5.– Longer timeframe with self-propelled applicator because of higher clearance.
How do we convince farmers their flat
rate program is deficient?• Farmer education
• Organic matter argument
