Detailed explanation-1: -The fillers in fertilizers are inactive ingredients and do not affect the plant. They do, however, reduce the concentration of the nutrients so that they do not burn the plants, prevent the nutrients from clumping and drying, and make the mixture easier to spread.

Detailed explanation-2: -Milorganite is non-burning, so it won’t burn your lawn or grass when you use it. Its 6-4-0 NPK means it’s low-impact and unlikely to cause fertilizer runoff damage to the environment. Also, you don’t need to water it in, which saves you time and effort. Milorganite is eco-friendly, safe, and has decades of reliability.

Detailed explanation-3: -Nitrogen, phosphorus and potassium, or NPK, are the “Big 3” primary nutrients in commercial fertilizers. Each of these fundamental nutrients plays a key role in plant nutrition. Nitrogen is considered to be the most important nutrient, and plants absorb more nitrogen than any other element.
