Natural fertilizer – Tips for my garden


natural fertilizer

Plants need essential elements to develop and grow. These are carbon (C), oxygen (O), hydrogen (H), which allow the plant to carry out “chlorophyll photosynthesis”, a chemical reaction that occurs in the green parts of the plant ( rich in chlorophyll) in the presence of light. ; the plant produces oxygen and glucose, the basis of most nutrients for itself and for all other living things. Plants are autotrophic organisms, heterotrophic animals. Other essential elements are Nitrogen (N), Sulfur (S), Magnesium (Mg), Phosphorus (P), Potassium (K), Sodium (Na), Iron (Fe), Calcium (That). They are essential elements for the growth of the plant, the production of seeds, the growth of fruits or the development of flowers. Without them, the plant could not grow. They are found naturally in the soil, in the layer called humus. In case of absence or insufficiency, a natural or chemical fertilizer is added to the soil. Natural fertilizer comes from the decomposition of plants and plant residues, so it contains the same elements as the plant but available in the form of mineral salts.

use fertilizer

Those who cultivate plants, for food or ornamental purposes, know that the success of cultivation depends fundamentally on the characteristics of the soil in which the plants grow. There are different types of soil, each suitable for the growth of various plant species. A “fertile” soil has a layer of humus, rich in all the chemical elements essential to the plant. Humus is nothing but earth mixed with dry leaves, animal and vegetable residues in decomposition, by bacteria and fungi present in the soil. Humus is a natural fertilizer. When to fertilize? Generally, the soil must be fertilized before use, to allow the plants to develop more quickly, then, depending on the type of crop, it is possible to carry out subsequent fertilizations. The fertilizer to be used must be adapted to the type of crop. Each plant has its own needs. The lack of certain elements produces effects on the leaves and on the other organs, from the stem to the flowers, passing through the fruits. Nitrogen is the most important element, its deficiency is called chlorosis, and is manifested by yellowing of the leaves due to lack of chlorophyll.

Natural fertilizer for the garden

The successful cultivation of vegetables depends on the soil. Fertile ground is a good guarantee of success. The garden should be fertilized before use because growing vegetables requires a lot of nutrition. Fertilization is done with natural or chemical fertilizers. In recent years, fertilization with synthetic products, considered more practical to use, has become widespread. Today, the increased demand for organic products and the awareness that chemical fertilizers pollute groundwater have caused a change in agricultural practices, a “return to the past”, with the use of natural methods. The natural plant fertilizer par excellence is manure, made up of farm animal excrement. Manure cannot be used fresh, but matured in the »

Natural fertilizer for plants

Most cultivated plants need fertilizer to grow. In particular, orchards and ornamental flowering plants. In late winter and early spring, the soil used for plant growth is fertilized, preferably natural, with compost, to enrich it with the necessary minerals. Compost is a natural fertilizer for plants produced with the so-called “wet” selective collection or vegetable waste. It is a product that contains all the essential elements for plants, in the right concentration and with a slow release. In home practice, other methods are also used to enrich the soil. Peat, decaying aquatic plants, which soften the soil; the ash, resulting from the combustion of plants, releases calcium, phosphorus, potassium and other elements; coffee grounds, rich in nitrogen, can be used directly mixed with soil or dissolved in water (it becomes an excellent liquid fertilizer); powdered eggshells, rich in calcium. The infusions obtained with officinal herbs are excellent liquid fertilizers.
