Molybdenum deficiencies are rarely a problem for gardeners. This is mainly because plants only require the nutrient in trace quantities. Areas which are more prone to such disorders include gardens possessing acidic soils. Molybdenum is responsible for the conversion of nitrate to ammonium. This takes place in the root nodules of legumes and is facilitated by symbiotic bacteria!
May affect Brassicas, including cauliflower and broccoli.
Cauliflower leaves grow elongated and twisted.
Symptoms are even more likely if the soil is acidic.
Apply lime at appropriate intervals during the year to increase the pH, taking care to follow the manufacturers' instructions.
