Zadco Synergizer Foliar NPK Liquid Fertiliser 11-19.5-4.6 18.92L at a glance

Synergizer® is a High Potency stabilised foliar Phosphorus buffered with humic acid for immediate availability. It has been formulated and designed to deliver a high potency of phosphorus to allow crops to reach their balanced nutritional requirements to maximise on yield performance and potential.

Synergizer™ contains Humax®, a concentrated humic acid, for increased uptake of nutrients through the leaves and translocation within the plants. The high levels of available NPK nutrients are recognised and absorbed rapidly. This eliminates the chance of applied nutrients, especially Phosphorous, from being fixed or tied up in the soil.

Synergizer™ can be applied at any time during the growing season, especially in accelerating early spring growth or supporting plants during extreme cold or hot weather conditions.

Benefits (manufacturer):

  • True solution of constituents NOT a solid suspension
  • Improves overall nutrient density of crop
