Leafy vegetables are regarded as group whose leaves and stems are eaten as vegetables. They also have an abundance of vitamins and minerals within them. The primary minerals present in green vegetables are magnesium, iron, calcium, potassium, vitamins C, E and K amongst others. Studies have shown that leafy vegetables have greater potential of accumulating heavy metals in their edible parts than grain or fruit crops as fruits and seeds have low transpiration rates. Indigrow have set out several guidelines for managing soils, fertilisers and soil amendments, and always recommend the use of fertilisers low in chloride, sodium and heavy metals which might have effects on health or an environmental impact.
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 B or Solar B when soil conditions lead to deficiency.
For raising seedlings for transplanted crops Numerica Ultra 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.
Cabbage, Broccoli, Cauliflower & Celery - A well as a balanced NPK nutrition, specific products, applied at the correct time can have a considerable influence on quality. High potassium products such as Solar K and Solar K32 can lead to increasing head weight and earlier maturity in cabbage, whilst the use of Solar B or IndiPlex B in broccoli, cauliflower and celery will lead to a reduction in internal browning and stem cracking caused by deficiency.
Lettuce & Spinach - Crops such as Lettuce can suffer from physiological disorders such as tip burn caused by calcium imbalance. Solar Ca+Mg and Nutrical can help 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.
