Roots are not simply smooth, long structures. In fact, they typically have tiny hairs that cover most of the roots' length. These hairs absorb water and soluble nutrients for plant success. However, some critical nutrients, like phosphorus, are not readily absorbed by plant root hairs. Soil micro-organisms, such as earthworms, consume the surrounding elements and expel castings rich in soluble elements.
  The answer is in the translation of NPK and what that means to plants. NPK is an abbreviation for nitrogen, phosphorous and potassium, the three main nutrients that stim â¦ ulate plant growth. The N of NPK relates to nitrogen, the primary nutrient that stimulates the growth of leaf and stem.Turf grass loves nitrogen because it's nothing but leaf and stem.Fertilizers blended for this purpose always have a very high nitrogen content and low phosphorous and potassium counts. There are different percentages of NPK fertilizers: For example some of them are 20-20-20 which means 20% Nitrogen 20% phosphorous and 20% Potas There are other perc â¦ entages also for example 15-15-15 or 10-20-10 or ... Base on the plants need different percentages are being used.
