The yield of fruit and vegetable crops depends on the fertile soil layer, and it can be supported by adding fertilizers or top dressing.
It is known that an excess of microelements is as harmful to plants as their deficiency; it is worth distinguishing the signs of a deficiency of certain elements.
To ensure that feeding is beneficial, we will tell you how to recognize a deficiency of nitrogen, phosphorus or potassium by eye.
Experienced gardeners claim that this can be done solely by the appearance of the seedlings.
The key components for any fruit-bearing crop are three elements: nitrogen, phosphorus and potassium.
If there is not enough nitrogen
In this case, the entire above-ground part, which is popularly called simply greenery, develops extremely slowly. Shoots do not grow, the lower leaves may begin to turn yellow, the upper ones become pale green.
If nitrogen supplements are not added, the seedlings will wither.
Phosphorus deficiency
It is simply impossible to make a mistake here, because with a phosphorus deficiency in the soil, the plant stem acquires a purple hue. At the same time, the leaves become darker than usual, covered with reddish spots.
Potassium deficiency
In this case, the edges of the leaves begin to turn yellow, after which the foliage begins to dry out, holes may form. The plant itself becomes lethargic.
Gardeners solve the problem by adding these elements separately or using complex additives.
