The success of the harvest will largely depend on how correctly you used fertilizers during the summer season.
If tomatoes have experienced a mineral deficiency, you should not expect a large number of large and sweet fruits.
In order to prevent a decrease in yield, it is necessary to determine in a timely manner what fertilizers tomatoes need, notes Anastasia Kovrizhnykh , an expert of the online publication BelNovosti, landscape designer and agronomist.
What external signs should you pay attention to?
Potassium deficiency
It is not difficult to determine the need of tomatoes for potassium. At the very beginning, the foliage begins to look dull, as if discolored. This should immediately alert the gardener.
If you don't apply fertilizer, the leaves will dry out.
Nitrogen deficiency
The problem begins to appear from the lower part of the stem, but over time other parts of the tomatoes also undergo color changes.
A characteristic sign of nitrogen deficiency is yellowing of leaves.
Phosphorus starvation
If tomatoes lack phosphorus, it will be immediately noticeable. As a rule, the green part of the tomatoes will turn a strange purple hue, which is an alarming signal.
