First, we will distinguish between the two large groups of fertilizers used organic and inorganic. Organic or natural fertilizers are born from the decomposition of animal and vegetable waste; they are better assimilated by the plant, are slow-release (long-term effect), are healthier for the soil by increasing the activity of microorganisms and improve their ability to retain nutrients.
Green fertilizer is the result of growing nitrogen-rich plants (legumes, for example) that are later cut and mixed with the soil. This type of fertilizer is very effective to enrich the soil, especially if it has suffered erosions or excess chemical fertilizers.
They can be obtained naturally, from minerals found in the earth, or they can be manufactured in laboratories. And although they do not generate any benefit to the soil or to its microfauna, thanks to its high concentration of essential nutrients and micronutrients it more efficiently supplements specific foods that the plants need. They are very enriching and especially used in gardening to replenish and maintain the fertility of the earth. Another advantage is its ease and speed to dissolve and, consequently, act.

Inorganic or chemical fertilizers:
You can use specific fertilizers for certain species, or universal, those are effective in all types of plants. The important thing is to look at the proportion of nutrients that each one has, according to the needs of your plants. For example, there are specific fertilizers of conifers, which need extra magnesium intake; or for acidophilic (hydrangeas, camellias, gardenias), which require a lot of iron; and also for cactus, rose bushes, geraniums and other flowering plants, orchids, fruit trees and even bonsai trees. Or for the lawn, which needs a slow release fertilizer especially rich in nitrogen. Each species and each season of the year has its requirements.
And as for the format of the fertilizer, we can choose it granulated (quick release, for large gardens), liquid (immediate effect, it is better absorbed and ideal for indoor plants or terrace) or soluble (recommended to meet specific deficiencies).
Some tips for fertilizing the lawn:
To get a perfect lawn, and as a general rule, the lawn should be fertilized twice a year, at the beginning of spring and in autumn, when the temperatures are milder. Thanks to the fertilizer, the lawn receives the basic nutrients it needs, especially nitrogen, which favours growth. Good fertilizers also contain potassium and phosphorus, which strengthen the lawn against possible diseases.
Before fertilizing, it is advisable to cut the grass (taking care that it does not measure less than 5 cm), clean it of weeds and aerates it using a scarified; it is important not to pay if the ground is frozen or too wet and avoid the hours with more sun. After the fertilization, you must water and let a few days pass before cutting the lawn again.
