  1. GOLF COURSE AND TURF SOLUTIONS PRESENTED BY GAVIN OLSEN

  2. WHERE ARE OUR COMPANY AND TECHNOLOGY ROOTS?

  3. HOW DO WE KNOW WHAT `SHAPPENING IN THE SOIL? DOES YOUR SOIL HAVE LOW ORGANIC CONTENT? DOES YOUR SOIL HAVE A BALANCED NUTRIENT STATUS? DOES YOUR SOIL HAVE MICROBIAL AND FUNGAL LIFE? DOES YOUR SOIL HAVE HIGH CLAY CONTENT ? DOES THE SOIL HAVE COMPACTION AND PERCOLATION PROBLEMS ? DOES YOUR SOIL HAVE A SALINITY OR ALKALINITY PROBLEM? DOES YOUR SOIL HAVE A LOW CATION EXCHANGE CAPACITY?

  4. THREE PROPERTIES OF ALL SOILS PHYSICAL : CLAY % ,CLAY PARTICLE SIZE OR 0% CLAY , SOIL PARTICLE SIZE ( SIZE COUNTS IN SOIL!) CHEMICAL : CATION EXCHANGE , CATION BALANCE PLANT TOXIC LEVELS OF SALTS ( IF YOU HAVE A SHORTAGE, HAVE IT IN BALANCE! ) BIOLOGICAL : ORGANIC MATTER , MICROBES AND FUNGAL ACTIVITY , CARBON % (IS YOUR ORGANIC MATTER FUNCTIONAL , SOLUBLE AND ACCESSIBLE TO THE GOOD GUYS!)

  5. PHYSICAL PROPERTIES CLAY % AND SIZE WILL INFLUENCE PHYSICAL QUALITIES SUCH AS : WATER HOLDING CAPACITY(PHYSICAL) :CATION EXCHANGE CAPACITY(PHYSIOCHEMICAL) :SOIL STRUCTURE AGGREGATION OR DISINTERGRATION(PHYSICAL) :WATER PERCOLATION (PHYSICAL) BUT IN 99.99% ANALYSIS OF GOLF GREENS THERE IS CLOSE TO 0% CLAY ??

  6. CHEMICAL PROPERTIES CATIONS HAVE DIFFERENT CHARGES AND SIZES(CHEM) CATIONS COMPETE ON CLAY AND ORGANIC MATTER FOR EXCHANGE SPACE(CHEMPHYSICAL) CATIONS MUST BE BALANCED , OTHERWISE DOMINATION OF OTHERS OCCUR (CHEM) CATIONS EXERT IONIC FORCES IN SOIL (CHEMPHYSICAL) INCORRECT FERTILISER CHOICE AND POOR QUALITY ARE SOMETIMES OUR BIGGEST ENEMIES ON SANDY SOIL!

  7. BIOLOGICAL PROPERTIES ORGANIC MATTER INFLUENCES ALL 3 PROPERTIES IN THE SOIL :CARBON MUST BE ACTIVE FRACTION (BIOCHEM) :INCREASES CATION EXCHANGE (CHEM) :FOOD SOURCE FOR ORGANISMS AND FUNGI (BIO) :SUBSTRATE FOR MICROBIAL ACTIVITY(BIO) :INCREASES SOIL AGGREGATION(PHYSICAL) :INCREASES SOIL MOISTURE(PHYSICAL)

  8. ORGANIC MATTER IS THE BEST SOLUTION AS IT ADRESSES ALL THREE PROPERTIES

  9. HOW AND WHY? • BUT HOW DOES ORGANIC MATTER WORK IN THE SOIL? • WHAT IS IT`S INTERACTION WITH CATIONS?

  22. Water quality deteriorated over treated period Irrigation reduced in treated period Less fertiliser applied in treated period Only 30 Kg of Ca/ha applied via CODA range over period Reduced sodium toxicity immediatley Increased water percolation Increased root growth Increased available nutrients in soil

  23. CONCLUSIONS • Sodium can be managed even at high levels • Percolation cannot be addressed with just mechanical intervention • Greens recovered quicker and maintained healthier looking root structure Good roots MEANS Good greens!!! Thank You!
