World-famous as a root soak and a foliar-applied plant fertilizer. Extracted from fresh Norwegian Ascophyllum kelp, using a process that concentrates all the goodness of the sea into a small amount of material.

1 lb of Maxicrop is created from over 200 lb of seaweed. Maxicrop is sought after primarily for its trace elements but also has an analysis of 0% N, 0% P, 17% K.

Note: Maxicrop uses two different processing facilities. The color of the maxicrop may accordingly vary from black to brownish, depending on the facility used. Beside the difference in color and a slight difference in texture, the solubility and NPK of the two different colors are the same.

  • Often combined with fish products or other high-analysis foliars.
  • Use the dry powder at 1 tsp/gal (shake to dissolve) or 1-2 lb/acre. Inject at 1-5 lb/acre.
  • For convenience, the 10.7 oz bag can be used to make one gallon of concentrated stock solution (stir or shake to dissolve thoroughly). Use the stock solution at 1-2 Tbs per gallon.
  • The dry powder will last indefinitely if keep dry. A liquid stock solution should be keep cool and used within several months.
