Shopping for fertilizer can be a little confusing. Typical fertilizer packaging consists of three numbers on the front of the bag. Each of those numbers is significant, and it is important a consumer understands the meaning behind the numbers before purchasing fertilizer. Before purchasing fertilizer, do a soil test to determine what nutrients the soil needs. Over fertilizing can essentially destroy a garden or lawn.
The first number represents nitrogen content. Nitrogen is a powerful and necessary fertilizer that all plants and lawns need. However, too much nitrogen can burn the leaves and potentially kill off a lawn. A 10-pound bag of fertilizer with the first number 20, indicates 20 percent of the 20 pounds is nitrogen or approximately 2 pounds of the bag.Confused? Here ‘s a little help .
Phosphorous is the second number. Phosphorous is needed to help plants and lawns have healthy roots. Plants lacking in phosphorous will likely be small and not produce much fruit. Roots can only absorb small doses of phosphorous.
The last number indicates potassium or potash. This is an essential nutrient to lawns and gardens. The potassium strengthens the plants and helps them withstand drought periods. Fruits and vegetable size is typically larger when the soil is rich in potassium.
