Abstract
A dry flowable fertilizer mixture is provided that contains soluble seaweed extract and fish solubles. Calcium silicate is added to the mixture to prevent excessive caking and thereby maintain the flowability of the fertilizer mixture. Chelated iron is also added to the mixture, preferably with EDTA. Chelated trace elements and micronutrients available from seaweed and fish solubles can thereby be made available to plants by applying a dilute solution of the fertilizer mixture.
