Grass quickly absorbs liquid fertilizers-both through its leaf blades and through its roots-but fertilizers also pass relatively quickly out of the soil. For the most part, turfgrass varieties react the same to synthetic fertilizers as they do to natural fertilizers. If applying an organic lawn product is important, it might be better to choose a granular grass food, which is more likely to contain ingredients such as composted manure or earthworm castings. Liquid lawn fertilizers often contain concentrated ingredients and are designed to be diluted before applying the product to the lawn. They are formulated in a lab, and the nutrients are the synthetic equivalent of nutrients found in nature. Most liquid lawn fertilizers are not organic, meaning they contain artificial and chemical ingredients. If it is, it can stimulate grass seed production, which can be helpful if the user wants the grass to reseed itself. Phosphorus may or may not be included in liquid lawn fertilizer. Potash is a form of potassium, but both serve the same purpose-to boost root growth and overall grass health. Occasionally the (K) in NPK stands for potash rather than potassium. A typical NPK ratio for liquid lawn fertilizers might be 16-0-6, which would indicate 16 percent nitrogen, 0 phosphorus, and 6 percent potassium. Most commercial fertilizers are labeled based on the amount of nitrogen (N), phosphorus (P), and potassium (K) they contain by volume. Lawn fertilizers are typically higher in nitrogen than any other nutrient in order to green up the lawn and promote robust growth. Gardeners concerned about the pH level should have their soil tested and then add amendments, such as lime or sulfur, to raise or lower the pH, depending on the results of the tests. While some fertilizers may help balance pH slightly, they won’t change the pH of soil that’s markedly too high or too low on the scale. The pH scale runs from 0 to 14, with 7 considered “neutral.” Numbers below 7 are progressively more acidic, and numbers above 7 are progressively more alkaline. Most turf grasses do best when grown in soil with a pH between 6.0 and 7.0. Consider some fundamental factors when shopping for liquid lawn fertilizer. Instead, they supplement relatively healthy soil to produce an attractive lawn. But, they’re not a cure-all for poor soil.
Most lawn fertilizers are similar-they contain the nutrients grass needs to produce rich color and grow steadily throughout the summer season.
