Answer to Question #252557 in Inorganic Chemistry for irene

Question

11. A golf course manager has a golf green that is thinning. A soil test indicates that the following:

CEC = 4 meq/100g            800 ppm Ca (soil)

pH = 8.4                                 48 ppm Mg (soil)

EC = 8 mmhos/cm             78 ppm K (soil)

                                                230 ppm Na (soil)

What would you recommend (lbs/1000ft²)? Show all calculations

Answer 1

CEC is an inherent soil characteristic and is difficult to alter significantly. It influences the soil's ability to hold onto essential nutrients and provides a buffer against soil acidification. Soils with a higher clay fraction tend to have a higher CEC.
