All living things need certain micro and macro elements, vitamins and other useful substances for health and normal functioning. Plants in this matter are no exception. The lack of some elements, for example, inhibits the growth of plants, the lack of others reduces fertility. Sometimes the problem is not in the lack of necessary elements, but in their abundance, and therefore it is so important to know what elements and in what quantity are contained in a particular soil. In this article, we will describe signs that will help you determine what is in excess in the soil and what is lacking in it.
What elements are missing in the soil
Signs of a lack of nitrogen in the soil: plant leaves turn pale, turn yellow, sometimes acquire a pinkish tint, curl and fall off. The plant grows poorly, does not bloom. Nitrogen fertilizers are applied in the spring, and how much they need to be applied must be determined in advance.
Signs of an excess of nitrogen in the soil: saturated dark green color of the ground part of the plant, stems too thick with obviously slow growth.
Signs of a lack of phosphorus in the soil: the leaves seem to bend up. Sometimes blue and violet shades appear on greens.
Signs of excess phosphorus in the soil: the plant ages too quickly from an excess of phosphate fertilizers . Leaves turn yellow, spots of necrosis appear.
Signs of a lack of potassium in the soil: burns along the edges of the leaves, while the leaf plate is rolled down, the leaves wrinkle. Insufficient amount of potash fertilizer in the soil can also cause curly leaves. With a lack of potassium, fruit trees bloom profusely, but the flowers crumble, resulting in very few fruits.
Signs of excess potassium in the soil: the plant seems to stretch, while it turns pale, becomes stained.
Signs of a lack of magnesium in the soil: leaves turn yellow, starting from the edges. The reason for the lack of magnesium is the frequent introduction of potash fertilizers into the soil.
Signs of excess magnesium in the soil: the leaves are getting dark, the young leaves are curled before they have developed.
Signs of a lack of zinc in the soil: leaves become smaller, lengthen, sharpen, and apical leaves become stained. In some plants, the leaves turn yellow, and then turn brown. Enriches the soil with zinc ordinary alfalfa.
Signs of excess zinc in the soil: healthy-looking adult leaves fall off, veins on them acquire an uncharacteristic red hue, and translucent spots appear around them.
Signs of copper deficiency in the soil: white leaf tips. Citrus plants are particularly sensitive to copper shortages.
Symptoms of excess copper in the soil: the leaves are covered with yellow or gray-brown spots.
Soil indicator plants
If you take the land for indoor flowers in the garden or in the meadow, then you should know that there are indicator plants by which you can determine which trace element is missing or, conversely, too much in the soil.
For example, raspberries grow well where the soil contains a lot of nitrogen. He loves nettle nitrogen, shiritsa and hops.
Clover and sundew, on the contrary, grow where there is little nitrogen.
Ferns grow well on soil rich in calcium. In soil with a low calcium content, violets and heather feel good.
Plants that indicate rich, undeveloped soil are the Lungwort, nightshade, and ostrich fern.
Small sorrel, blueberries, lingonberries, cranberries grow quite normally on poor, depleted soil.
