  1. TAKING THE PULSE OF TURFGRASS Planet Turf Winter Seminar

  2. PLANET TURF • Sales Reps • Jason Otto – W. WA, OR • Jim Connolly – E. WA, ID, MT, International • Jared Whitaker – E. WA, ID, WY, MT • Distributors • Turf Health Products, Canada • Riken Green, Japan • Total Green, Korea • Sales to… • PNW, Asia, Guam, Malaysia, Kansas, Missouri

  3. JIM CONNOLLY Owner, Planet Turf since 1999 BS Agronomy WSU, 1974 UCONN, environmental science WSU Crop Science USGA agronomist, 6 years Owner, Planet Turf since 1999 Superintendent – Oregon, Korea, Japan

  4. PRODUCT LINES • FOLIAR AND SOLUBLE POWDERS • MADE IN PASCO • HOMOGENEOUS GREENS FERTILIZER • MADE IN CALGARY BC • SOIL AND TISSUE TESTING • OTELLO WA BY KUO TESTING • GRASS SEED • JACKLIN SEED COMPANY • JACKLIN SEED • POST FALLS IDAHO, SOON TO BE OTHELLO WA • PESTICIDES • UNITED TURF ALLIANCE PESTICIDES, NUFARM, QUALIPRO, BASF, ARYSTA, MONSANTO • PLANET AIR • CERES/CTI TINES • EAGLE ONE • STANDARD GOLF, PAR AIDE, FOREPAR, WITTEK

  5. TODAY’S AGENDA Ways we try to measure and monitor factors that affect plant health Ways to directly measure the content of plant nutrients – the blood test Ways to measure the mineral content and make up of soil – environmental test Laboratory Procedures Data

  6. WHAT IS THE PULSE? THE STATE OF HEALTH BLOOD PRESSURE FLUIDS MEASUREMENT OF HEALTH MEASUREMENT OF PRODUCT APPLICATION EFFICIENCY

  7. SOIL HEALTH • The Capacity of the Soil to Function – NRCS • It is like a factory full of workers with more workers in one teaspoon of soil than people on earth • Good, Healthy Soil • Organic Matter Balance composed of 2-10% Organic Matter • Balanced Minerals • Water entry and storage – balanced capillary and non capillary • Maximize microorganism populations – absence of disease • Productive • Enhances community well being

  8. REFRACTOMETERS Refractometer $100 -$400 Useful? Probably Not Used for measuring sugar in my beer Refractive index of a glass prism to measure the refractive index of a liquid Limited use for turf

  9. INFRARED THERMOMETER $<40 at Harbor Freight

  10. CHLOROPHYL METER SPAD $2500.00 Measures Measures green color – chlorophyll - - red Leaf N content Web Mapping Used mostly by researchers

  11. MOISTURE STRESS METER, NITROGEN LEVELS $2790.00 Detects stress earlier than visual monitoring “Point-and-shoot” technology to instantly measure relative chlorophyll content

  12. PHONE APPS $99 PHONE APP Manage nitrogen needs Computes the dark green color DGCI number For corn now

  13. SOIL TOOLS $1100 $50

  14. WHEN THINGS GO WRONG …WHAT DO WE LOOK FOR? LOW YIELD - clippings DISEASE SLOW RECOVERY FROM DAMAGE YELLOW GRASS ???? WHAT ELSE???? IF YOU ARE SEEING THESE THINGS…ITS TOO LATE

  15. MANAGEMENT TRIANGLE PHYSICAL aeration Verticutting Topdressing Fertilizer Pesticides Irrigation Feed the soil Microbes CHEMICAL BIOLOGICAL

  16. HEALTHY SOILS • PHYSICAL • ISTRC Non Disturbed Soil Core • All physical parameters - - how far are you from a new USGA GREEN • Infiltration • Porosity • Layering Extent • Organic Matter

  17. CHEMICAL SOIL TESTS Calcium Magnesium Boron Copper Iron Zinc Manganese Ec Nitrate Ammonium • Total Bases or CEC • pH • Organic Matter • Base Saturation • Ca, Mg, K, Na, H • Nitrogen • Phosphorus • Potassium

  18. STATEMENT OF METHODOLOGY THE MOST IMPORTANT QUESTION

  19. OBJECTIVE OF A SOIL TEST • The estimation of bioavailabilityof nutrients is the objective of a good soil test • Capsules exchange anions (OH-)and cations (H+) for available forms of nutrients over a period of time. • Conventional soil testing uses extracts to estimate nutrient availability • Bioavailability:“Those chemicals in the soil that are present in forms and amounts that plants (or other organisms) can take up during the time they are growing.” UNIBEST International

  20. Example - -Iron exists in Fe+++, (ferric) • Must be changed to Fe++ (ferrous) • Reduced by a protein at the root surface protein Fe+++ Fe++

  21. Aug 30 1.2 lb

  22. Nitrate:ammonium ratio +1

  23. SOIL NITRATE TO AMMONIUM RATIO

  24. PLANT GROWTH HABIT VS. UPTAKE

  25. TARGET RANGES FOR TISSUE

  26. TARGET RANGES FOR SOIL

  27. How do IERC’s Measure Nutrients Resin Capsule H+ Diffusion K+ H+ K+ K+ Soil Particle K+ K+ K+ OH- Mass Flow NO3- NO3- H2O UNIBEST International

  28. Turfgrass Report Customer: Chang Gung Golf ClubDate of Sample: 3-26-12 City: State: Bar Code #: 2006064 Sample ID: This green is low in almost every nutrient, and shows a need for frequent applications, every week, of each low nutrient. Low amounts each time – do not apply high rates.
