Milorganite

Salt Index Chart


Quick Tips:

1. Milorganite is non-burning, you can apply in the hottest of temperatures.
2. Milorganite is a great starter fertilizer for seeding or sodding projects. It will not burn young seedlings or new roots.
3.

Non-burning Milorganite

Milorganite contains virtually no chemical salts.  Chemical salts, found in high concentrations in most synthetic fertilizers, can dehydrate and burn plants.  This is especially true in low moisture conditions.  Droughty soils add to this burn potential.

Damage from Salts

Salts can also build up in the soil to create residual concentrations.  If you are watering with “gray” or effluent water, you are adding salts to your turf.  Using Milorganite, with its low salt content, doesn’t add to the salt burden of your soil.  Plants can only tolerate a finite amount of soil salts.
