No one may sell turf fertilizer at retail that is labeled as containing phosphorus or available phosphate if the person knows that the purchaser intends to use the fertilizer for a purpose other than one of the following:
- The purchaser is establishing grass either by seed or sod, during the growing season in which the purchaser began establishing the grass.
- The purchaser is applying the fertilizer to an area that is deficient in phosphorus as shown by a soil test performed by a laboratory no more than 36 months before the application.
- For application to a pasture, land used to grow grass for sod or any other land used for agricultural production.
- Anyone who sells fertilizer at retail may not display turf fertilizer that is labeled as containing phosphorus or available phosphate. In other words, keep it off your sales floor.
- However, a fertilizer retailer may post a sign advising customers that turf fertilizer containing phosphorus or available phosphate is available upon request for uses listed above (establishing grass or a lab test shows phosphorus deficiencies in the lawn or the product will be used for agricultural production.)
- Any one who violates regulations on the sale or display of fertilizer containing phosphorus or available phosphate may be required to pay a penalty of not more than $50 for a first violation and not less than $200 nor more than $500 for a second or subsequent violation.
