Ask yourself: is this the moment for Moly?

If it has been five years or more since you last applied molybdenum to pastures on acid soils, consider it as an addition to your fertiliser program this year. Moly allows you to enhance pasture production using free nitrogen. Things to consider:

  • Are your soils and pastures prone to molybdenum deficiency? (n.b. this is more likely to be the case if your soil is acidic).
  • Molybdenum deficiency is also more likely to occur on highly weathered limestone soils that are low in native phosphorus, potassium and calcium.
  • If it is considered that there is a need for molybdenum, then testing with a leaf tissue test through the Nutrient Advantage® laboratory is a very good starting point.
  • Tissue testing measures the availability of molybdenum to your pastures. It is the most reliable method for diagnosing molybdenum deficiency.
  • If you are looking for a deficiency, you’ll probably see it first in legumes such as clovers, medic and lucerne, with stunted growth and a general paleness, similar to nitrogen deficiency. Rhizobium nodules may become pale and colourless too.
