NITROGEN DEFICIENCY IN FRUIT AND VEGETABLES
Nitrogen is essential for all plant growth - it forms part of the protoplasm of plant cells and chlorophyll.
The presence of Nitrogen in the soil promotes foliage, vigour and general growth.
Nitrogen is released into the soil as a result of bacterial activity, and is usually abundant by the end of the summer.
Nitrogen is easily lost from the soil by the effect of Winter rain.
A deficiency can also happen when woody material like sawdust, sometimes contained in horse manure, is dug into the soil. The organisms in the soil will use nitrogen to break the wood shavings down, which makes it unavailable to any plants growing in that soil..
SYMPTOMS OF NITROGEN DEFICIENCY
The main symptoms of nitrogen deficiency in all types of plants are
- Restricted or stunted root and top growth
- Stunted, thin shoots
- Upright , spindly growth
- Small pale green or yellow leaves
- Premature leaf fall
- Poor lateral growth development
These symptoms of nitrogen deficiency are common in the Brassicas - Cabbage, Cauliflower, Brussels Sprouts and Beetroot.
Potatoes affected by nitrogen deficiency are stunted and the number of tubers much reduced.
Fruit trees and fruit bushes with a nitrogen deficiency exhibit short thin shoot growth, sparse foliage in adddition to the main symptoms with few blossoms and any fruits that are produced are small and highly coloured.
CORRECTING NITROGEN DEFICIENCY IN THE SOIL
Nitrogen Deficiency can be corrected by the application of nitrogenous fertilizers and manures such as sulphate of ammonia, dried blood and sodium sulphate and well rotted farmyard manure (provided that the manure does not contain wood shavings) or chicken manure pellets
In the long term, the addition of organic material to
the soil will maintain levels of nitrogen by producing a small but steady
amount of nitrogen as it rots down..
