Farm vs. specialty fertilizers
Lawns can be fertilized with specialty turf fertilizers (normally available at local garden centers) or with farm fertilizers. The main advantages to the specialty fertilizers are:
•Normally good nutrient ratios for turf.
•Uniformity of particle size.
•Low burn potential.
•Calibration and application rate information printed on the bag.
Most farm fertilizers do not have these advantages, but farm fertilizers are usually three to five time less expensive.
