Magnesium Nitrate Fertilizer 11-0-0 is a CDFA-registered, 100% water-soluble fertilizer that delivers two essential nutrients in a single application: 11% nitrate nitrogen and 9.6% magnesium. The nitrogen is supplied entirely as nitrate, so it is immediately plant-available with no microbial conversion step and stays available even in cool soils.
Magnesium is the central atom of every chlorophyll molecule and activates key plant enzymes; deficiency typically shows as interveinal yellowing on older, lower leaves. This product corrects both nitrogen and magnesium needs at once in a pH-neutral carrier that will not acidify the root zone. It dissolves completely with no residue, making it well suited to hydroponic Tank A programs, fertigation, soil drench, and foliar correction, and it is compatible with calcium nitrate in concentrated stock.
Add the fertilizer to water and stir until clear; apply foliar sprays in early morning or late afternoon, and keep foliar rates well below soil rates. Keep separate from concentrated phosphate stock tanks.
Independently lab tested for heavy metals, with results consistently well below required limits.
