There is a vast array of leafy vegetable crops grown including Lettuce, Cabbage and Spinach as well as many sub-tropical salad crops. In general they need a balanced NPK nutrition but have a general requirement for higher Nitrogen fertilisers which can be in supplemented with applications of Fusion Liquid and Soluble feeds as well as Orbit foliar feeds.

Crops such as Lettuce can suffer from physiological disorders such as Tip Burn caused by Calcium imbalance. Datum Ca, Orbit Ca+Mg and Nutrical can largely overcome these problems. They can also increase head weight and keep the produce in marketable condition for longer with less wastage at the point of sale.

For Organic production the use of Joust and Protaplex can help during periods of environmental stress, whilst Celery, Broccoli and Cauliflower will benefit from applications of Indiplex Boron or Orbit Boron when soil conditions lead to deficiency.

Magnesium is a vital constituent of the chlorophyll molecule and Orbit Magnesium will ensure that mature crops are presented in an acceptable way.

Stratum N is a stabilised urea/calcium based fertiliser that promotes reproductive growth, root growth, and stress tolerance. It is highly efficient at keeping nitrogen in a form that can be taken up efficiently by the plant without being lost through leaching or volatilisation of ammonia, thereby allowing maximum productivity from minimum applied nitrogen.

The control of diseases can be problematic, particular under high temperature and humidity. Numerica formulations will ensure that plant health and resistance to disease is optimised. A number of formulations are available suitable for foliar application or inclusion in fertigation programmes.

For raising seedlings for transplanted crops Numerica NPK has proven to increase plant rooting, establishment and vigour, speeding up seedling growth and development. It is normally applied as a foliar application from very early establishment.
