First-Mag
First-Mag liquid magnesium is a natural compound formulated with natural organic sugars of glucoheptonic acid. Sugar acids have the capacity to form multi-bond, water soluble complexes with various metal ions resulting in a very stable product that remains available in the soil or fertilizer for uptake by crop. First-Mag liquid magnesium is nonphytotoxic and safe to use as foliar application in X-0-X fertilizer grades on most plants. It is recommended for use throughout the season in a program of multiple applications for greater efficiency. This provides a continuous supply of vital nutrients at or near the time they are needed most and under all growing conditions including insect and disease pressure, leaching and drought that often interrupt nutrient supply.
