The first number indicates the percentage of nitrogen in the fertilizer, the second number is the percentage of phosphorus and the third is the percentage of potassium. Potassium is water soluble and so it gets washed away if too much is there which is why you have to apply a little bit 2-3 times throughout the year. When there is too much phosphorus in the soil, the plant’s ability to take up necessary amounts of iron is compromised.

Too much phosphorus can hurt the plant’s chlorophyll production which leads to yellowing leaves (called chlorosis). 6-0-4 Low Phosphorus In most cases yellow leaves which begin turning yellow at the base of the plant first are due to one Although results show a very slight reduction (1%) in samples exceeding 200 ppm Mehlich-3 P between the two 6-year increments (January 1, 2004 to December 31, 2009 and January 1, 2010 to December 31, 2015), it's too soon to determine if a trend is occurring towards reduced P in lawn soils.
