For this reason, we have prepared a guide to buy the best fertilizer, in order to help you select the one that provides the greatest benefits to your plants.


Organic fertilizers are in high demand among gardeners and environmental groups.

However, these wastes must be processed properly so that they are not harmful. In this aspect its use and different types are derived.

One of them is the fertilizer prepared with manure, which comes from the waste of certain animals that have not ingested antibiotics in their diet, such as guano, palomina, chicken manure, manure, among others. This type of fertilizer is usually available in gradual release granules that release their nutrients over a period of 2 to 3 months.

Phosphorus allows the rapid formation and growth of roots, regulates the life cycles of plants, causes the formation of seeds and gives them the necessary strength to withstand the winter. For its part, potassium is the most important element in terms of plant production, since it provides the necessary vigor and resistance against diseases and low temperatures. Also, it facilitates protein production and transports sugar from the leaves to the fruit.

Other elements that reinforce its properties but are used to a lesser extent are boron, copper, manganese and zinc, which contribute to cell division for the creation of new plants.
