How Milorganite Works
Your Plants Require Three Elements to Flourish: Sunlight, Water and Nutrients.
Sunlight is necessary for photosynthesis, which produces chlorophyll, the element that gives plants their green color. Plant roots absorb water and nutrients from the soil to keep the plant healthy and strong. Water carries chlorophyll throughout the plant and helps plants absorb nutrients.
Milorganite Releases Nutrients as Plants Need Them
Milorganite’s slow-release nutrients are available as plants need them. There’s no immediate, excessive release of nutrients after fertilizing, which causes a flush of growth.
At least 60% of the nitrogen in Milorganite is water insoluble and is delivered to the roots through microbial activity in the soil, but the conditions need to be right. Microbial activity occurs when soil moisture is adequate and soil temperatures are 55–85 F. The microbes break down the nutrients from Milorganite making them available to plants. When conditions aren’t favorable, Milorganite’s nutrients stay right where they are until there’s enough water and the temperature is within range.
Slow-release nutrients, like those in Milorganite, are gradually available for up to 10 weeks, which means fewer applications. This extended feeding provides more uniform growth, a deeper and better-established root system, and a healthier lawn. Slow-release nutrients are also better for the environment, because the nutrients are less likely to leach into waterways.
Essential Plant Nutrients
Healthy plants need more than nitrogen, phosphorus and potassium. Fortunately for your lawn and plants, Milorganite contains all 13 essential plant nutrients, including secondary nutrients like calcium and micro-nutrients such as iron and zinc.
|Primary Nutrients||Secondary Nutrients||Micronutrients|
|Nitrogen (N) 5%||Calcium (Ca) 2.1%||Iron (Fe) 2.5%|
|Phosphorus (P) 4%||Sulfur (S) .58%||Zinc (Zn) .045%|
|Potassium (K) .32%||Magnesium (Mg) 0.68%||Copper (Cu) .022%|
|Manganese (Mn) .133%|
|Boron (B) Trace|
|Chlorine (Cl) Trace|
|Molybdenum (Mo) Trace|
