Test soil to find out what nutrients are available. Nitrogen, phosphorous, calcium and potassium are crucial to plants. Fertilizers contain varying amounts of each nutrient. Test soil by hiring a professional or by using a home testing kit.

If sod becomes yellow and appears to be growing poorly, add fertilizer no sooner than a month after putting down sod. In this case, ask the sod supplier when the sod was fertilized.

After fertilizing the first time, follow guidelines from an agricultural extension office for your area on how often to fertilize your specific type of grass.
