If a plant lives in a wild place, it has everything it needs to live in good conditions. The earth is rich in nutrients due to the action of animals and insects and microorganisms typical of the place. Some soils also receive minerals from the waterways found in the area.
But this does not happen when the plants are grown in pots or in confined places. The soil can never be the same, thus losing a large part of its virtues. You can tell when the soil needs nutrients just by looking at it. When the earth is hard and not very spongy, it is the moment of the alert because it is a symptom of the lack of nutrients, which have been washed away with successive irrigations.
Chemical fertilizers
Let us remember that to carry out photosynthesis and grow in harmony, plants not only need the sun and water but also nutrients, among which are many minerals such as nitrogen, phosphorus, potassium, iron or zinc. When these are lacking, it is necessary to resort to a series of fertilizers in order to give the earth all that it lacks. There are of two types: chemical fertilizers and organic fertilizers.
They are the simplest and easiest to get because you just have to go to the store and buy a bottle. In addition, they are effective and achieve good results although they also have a cost since there are certain disadvantages of chemical fertilizers that appear, above all, in the long term.
Disadvantages
The chemical fertilizers are not natural y that is why its composition alters the chemistry of the earth as well as its PH affecting the microbacteria that live in it and that are largely responsible for the development of plants. This means that, in the long term, the use or abuse of chemical fertilizers ends up affecting the ecosystem and plant growthwhich end up becoming weaker and more prone to disease.
But there is another point against him and that is that it is frequent that chemical fertilizers contain a large amount of nitrogen while they do not contain other important nutrients, the consequence of which is an increasingly acidic soil.
