How to Calibrate Your Fertilizer Spreader

Travis W. Shaddox, J. Bryan Unruh, and Laurie E. Trenholm

Fertilizer application is only effective if you ensure uniform coverage. Dry fertilizers can be applied with either a drop spreader or a rotary spreader. This publication provides step-by-step instructions for adjusting the sprtead pattern to distribute the fertilizer particles uniformly; then measuring and adjusting the amount of fertilizer spread over the desired area to equal the recommended application rate.

Urban Turf Fertilizer Rule for Home Lawn Fertilization

Laurie E. Trenholm

While a healthy lawn typically takes up and uses applied fertilizer for growth and protein production, nutrients may leach or run off into water bodies or groundwater when fertilizer is overapplied or applied to an unhealthy lawn. In an attempt to reduce this nonpoint source pollution, FDACS developed a rule to regulate the amount of N and P applied to lawns as fertilizer. The Urban Turf Fertilizer Rule regulates what can be sold and marketed as an urban turf fertilizer and requires specific wording on the fertilizer bag. This rule was enacted in response to concerns over potential pollution of water resources resulting from the nitrogen (N) and phosphorus (P) in these fertilizers.

Homeowner Best Management Practices for the Home Lawn

Alex J. Lindsey, Marco Schiavon, J. Bryan Unruh, and Laurie E. Trenholm

A healthy lawn is an important component of an urban landscape. Not only do lawns increase the value of a property, but they also reduce soil erosion, filter stormwater runoff, cool the air, and reduce glare and noise. A healthy lawn effectively filters and traps sediment and pollutants that could otherwise contaminate surface waters and groundwater. This publication is intended for those who maintain their own lawn and landscapes.
