5 Uptake (lbs/a)

6 Spread Nutrients Out Over Time & Space Time Fall/winter Spring At Seeding In crop Space With seed Near seed Mid row On top Broadcast Streams/band

7 Mimicking Mother Nature... Fertilizer Placement and Other Strategies to Achieve Season Long Crop Nutrition

9 WUE, NUE 1 of rain N grows 130 lbs of wheat grain

10 WUE, NUE 1 lb of fertilizer N grows 40 lbs of wheat grain

12 Three most essential, but often unmanaged, inputs to crop production?

13 Maximizing Photosynthetic Efficiency Oxygen Nitrogen Hydrogen Carbon 6CO 2 + 6H 2 O C 6 H 12 O 6 + 6O 2 Nitrogen Potassium Magnesium Zinc Calcium Chloride Phosphorus Oxygen Sulfur Manganese Copper Boron Iron Molybdenum

14 Our Job Maximize the conversion of solar energy into energy stored in agricultural produce. BUT IT S MORE THAN THAT Lysine C 6 H 14 N 2 O 2 Methionine C 5 H 11 NO 2 S Cysteine C 3 H 7 NO 2 S Optimize the amount of the other essential nutrients like protein, minerals and vitamins that ends up in the foods we produce.

15 Water Use Efficiency 1 st 4 goes to the factory unless you re corn & the 1 st 8 goes to the factory Every 1 after that goes to yield Prof. Les Henry Water in the soil is $$ in the Bank! Nobody measures it!!

29 The 7R s of Yield, Quality, Maturity, Profitability and Sustainability

31 Think Like a Plant

32 The 1 st thing a young plant wants to do is..... GROW ROOTS!!

33 Growing Roots 80% of a plants biomass in below the soil surface Each plant only explores ~2% of the soil volume that supports it

34 Nutrient Mobility In Soil: In Plant: Very Mobile: Nitrate, Sulfate, Chloride & Boron Moderately Mobile: Ammonium, Potassium, Calcium, Magnesium, Molybdenum Immobile: Phosphorus, Copper, Iron, Manganese & Zinc Mobile: Nitrogen, Phosphorus, Potassiu Magnesium, Molybdenum, Chloride Immobile: Boron, Calcium, Copper, Iron, Manganese, Nickel, Sulfu

35 Nutrient Uptake

36 The 2 nd thing a young plant wants to do is..... GROW SHOOTS!!

37 Planting Considerations More Plants = More Photosynthesis Other Considerations Row Spacing SBU Yield Environment

40 Spike Count/ft2

41 Think of Your Crop as a Solar Panel Radiation Adsorption CO 2 Assimilation Focus on: Early Rooting Early Chlorophyll Results in: Improved WUE & NUE More yield & quality Rapid Maturity

42 Think Solar Panels!! Think Early Chlorophyll! Find Synergy!! Think Magnesium (Mg) Think Cu and Mn catalysts A big solar panel: hastens maturity, competes with weeds, hedges bets to higher yield & quality

43 Leaf Green Area Index What the heck is this?? How much solar panel is created quickly per unit area of soil surface being cropped/
