Fall is a Great Time to Fertilize Lawns
The September issue of Purdue’s Turf Tips (http://www.agry.purdue.edu/turf/tips/2010/09102010_fertilizer.html) has a few simple and straightforward recommendations for lawn care:
The amount of nitrogen fertilizer required by turf depends on various management and environmental/management factors. A good rule to follow is to never apply more than 1.0 lb N/1000 sq. ft. in any one application.
So the question remains, what type of fertilizer to use? There are many different brand names, marketing tools, as well as different analyses of fertilizer. All these factors can make the decision on which fertilizer to use seem a bit confusing. Purdue offers the following advice:
There are many fertilizer choices available to the professional and the homeowner. Organic, inorganic, and synthetic organic products are all available. As with all plants, turfgrasses cannot tell the difference between the sources of nutrients. Some products contain high amounts of slow-release N while others contain none. Our recommendation is to use a mixture of quick and slow-release nitrogen sources in most situations. Although there are exceptions to the rule, it is good practice to use products with a greater percentage of slow-release nitrogen sources during warmer months and a greater percentage of quick-release nitrogen sources during cooler times of the year. Your soil test report will help you to choose which fertilizer might work best for your lawn.
