- 12. Attention to detail iskey to success in all types of farming

- 41. Precise banding willprobably be needed for ROI
- 42. What is PRECISIONCOVER CROPPING??? 1) Planting of cover crops with a precision planter 2) strategic placement of cover crop rows in relation to other cover cover rows and/or the following cash crop rows (often using GPS guidance) 3) Strategic placement of cover crops in specific fields or parts of fields 4) Selection and management of cover crops to achieve specific objectives

- 47. Attempt #3 Radishplanted on 30” rows using small milo plates in mid-August 2010
- 48. Corn following covercrop experiment (2011) Relative Cover crop system corn yield Volunteer oats 79% Radishes planted on 30” 99% Radishes drilled on 7.5” 91% Corn planted directly over radish rows
- 49.
- 50. Radish planted on30” rows with RTK guidance on August 29th right before Hurricane Isaac rolled in
- 51.
- 53. 7 days afterplanting
- 54. 10 days afterplanting
- 55. ~ 1 monthlater
- 56. Why are theinter-rows so clean?
- 57. We had justcultivated the radishes! +20 bu/a corn in plots w/ fall cultivation vs. no cultivation of radish in 2012
- 58. ~ 2 weekslater
- 60. December 2012 We are planning to plant corn directly over the radish rows in 2013
- 61. Precision radishes w/opeas Precision planted radishes w/ peas from 5 ft of row Radishes with peas were ~20% larger
- 62. Crimson Chick clover peas We are using small plots to identify cover crops that play well together Green Fava lentils beans
- 63. Sunflower Oats Rapeseed Phacelia
- 64. Do you want bothspecies to winter kill?
- 67. Planted with adrill in late September 2012 Precision planting may allow you to plant your cover crops later Radish Radish Radish Cereal Cereal Rye Rye
- 68. Little radishes can have long roots!
- 70. Would you becomfortable planting a field in this condition?
- 71. Planting right on top of ridged radishes
- 72. Last fall weset up a 6 row bar with Yetter Mavericks We plan to freshen rows before planting as needed
- 73. Why is thererapeseed on the edge of this bean field? We ran rapeseed (2 lbs/a) through insecticide boxes while planting these soybeans
- 74. 40 lbs ofcereal rye planted directly over soybean rows in 2011 The cereal rye and rapeseed both died when the crop canopied. No significant effect on yield, some in-row weed suppression in 2011
- 75. Insecticide boxes doa good job of metering small seeds
- 76. A little extraN can make a big difference +20 lbs N/a
- 77. Triple S mix Sunflowers,Soybeans & Sunnhemp
- 78. What do you thinkis in this CC cocktail?
- 79. You won’t really knowwhat is in a mix unless you design it.
- 80. Aerial seeded annualryegrass in April 2012
- 81. 10’ Howard Rotavatortilling ~ 3” deep with C blades
- 82. Annual ryegrass afterchisel plowing Chiseling before rotavating worked best!
- 83. Planting into poorlydigested red clover residues 25-50% stand loss Near perfect stands in all other corn plots on the farm this past spring
- 84. Organic No-till? Much less weed seed germination Rodale roller …but few options for weed termination Cultimulcher
- 85.
- 86.
- 87. Early November 2009 Plotyields ranged from 51.6 to 58.6 bu/ac No significant differences between systems
- 88. November 2010 Significant foxtail pressure but almost no broadleaf weeds Plot yields ranged from 42-52 bu/ac
- 89. November 2011 The NTbean plots yielded ~10 bu more than the best tillage system plots

- 92. Double drilled with4” offset
- 93.
- 94. All of July:-<
- 95. NT bean yieldsranged from ~ 30 to ~ 60 bu/a 60 b/a in wet hole 30-40 b/a in well drained areas
- 96. Our cleanest andbest yielding beans in 2012 were conventional-till but we have not been able to achieve this level of weed control every year.
- 97. Where are thesoybeans?? Traditional organic weed management often comes up short during wet years A strong stand of cereal rye was incorporated ~ 2 weeks before these soybeans were planted
- 98. CCs affect manyagronomic factors simultaneously Control erosion Feed livestock Cover Crops Adapted from Magdoff and Weil (2004)
- 99. Not all effectsare positive Host pests Tie up N ? ? Become a weed Interfere w/ equipment performance Suppress crop growth Cover Crops Dry out soil Prevent excessively soil drying Add cost Increase management Adapted from Magdoff and Weil (2004)
- 100. Greater precision infarming practices increases the likelihood of intended outcomes More positive and fewer negative effects
- 101. This is whatwe were hoping for in the field where we ended up planting our precision radish experiment in fall 2012!
- 102. This is whatwe may end up with :-<
