NPK fertilizer

Fertilizer

To develop in the best way, plants need to be fed and watered constantly. The nutrients they need are taken from the soil used for cultivation. Often, however, it happens that the soil does not provide all the elements the plant needs and therefore we should resort to fertilization. Fertilizers, whether chemical or organic, are indispensable for the plant because they allow nutrition and plant growth. In fact, they accompany plants in all their stages of growth and development. Remember, however, that every species of plant needs particular nutritional elements and not all soils contain the same elements. Having said that, first of all, it is necessary to analyze the soil and know the plant before choosing the type of fertilizer to buy and use. Generally, each fertilizer is made up of several elements useful for plant growth. These elements are divided into two small groups: macro elements and micro elements. In the group of macroelements there are Nitrogen, Phosphorus and Potassium; in the group of microelements there are Copper, Boron, Zinc, Manganese, Iron, Cobalt, Molybdenum, Silicon, Chlorine and Nickel. More attention is focused on fertilizers composed of macro elements.

NPK fertilizers


NPK fertilizers are those fertilizers consisting of macroelements such as Nitrogen, Phosphorus and Potassium and are called «ternary» because they are composed of three elements. The acronym NPK derives from the chemical symbol of the three elements of which the fertilizer is composed and N stands for Nitrogen, P stands for Phosphorus and K stands for Potassium. Fertilizers made up of these three macroelements are the most used and most important fertilizers for plant growth and nutrition. In the absence of these substances, the plants could find themselves in difficulty and would not have a good development. Often, potassium is an element already present in the soil used and therefore must be administered in smaller quantities than nitrogen and phosphorus. Fertilizers must be administered according to a percentage (title) which is shown on the packaging of the product we are going to buy. The title is very important because it establishes the quantity of NPK fertilizer that we will administer to the plants to ensure good nutrition and excellent development. These three elements are important because nitrogen promotes development and guarantees color to the leaves, phosphorus strengthens the root system and guarantees excellent flowering and potassium strengthens the plant to resist adversity and guarantees flavor to the fruit.

As previously written, the fertilizers must be administered following a title, or a percentage. In NKP fertilizers it is not only the percentage that must be evaluated but also the formulation. These types of fertilizers are generally chemical or mineral, that is, they are the result of industrial processes or chemical reactions. Furthermore, fertilizers can be in liquid, granular or powder form. Liquid fertilizers are those that must be assimilated more quickly by plants and therefore it is advisable to administer a low content of elements. The granular ones are fertilizers that release nutrients in a slower way and guarantee nutrition for about 90 days. Powder fertilizers are compound fertilizers, that is, in addition to containing Nitrogen, Phosphorus and Potassium, they also contain microelements. Liquid fertilizers and powder fertilizers are usually administered by diluting them in the water used for watering. In granular fertilizers, in order to avoid nutritional deficiencies, the percentages of Nitrogen, Phosphorus and Potassium must be increased compared to the others.

NPK fertilizer: Uses and consumption

From what we have been able to understand there are various types of fertilizers, each of them is suitable for some particular situation. There are various existing fertilizers because each of them must be able to cover all the development phases of each single species and each single plant. NKP fertilizers, for example, are not always suitable for all plant growth stages. For example, in the case of a lawn, during spring fertilizations it is preferable to first administer urea or ammonium nitrate (the effect lasts about twenty days) and then administer an NKP fertilizer following the formula 20:10:10. The peculiarity of NKP fertilizers is that they are fertilizers that are easily and quickly absorbed by plants and the soil. Liquid NKP fertilizers are those fertilizers that must be used in the final stages of the development of vegetable and flowering plants in the greenhouse. The formula to follow is one in which nitrogen and phosphorus will be in lower quantities than potassium. Fertilizers with higher quantities of Nitrogen and Potassium are slow release granular ones and should be used before the summer and before the winter. On the other hand, fertilizers with an average dose of Nitrogen, greater quantities of Phosphorus and fewer of Potassium are those used for young specimens of seedlings. Fertilizers with higher quantities of Nitrogen and Potassium are slow release granular ones and must be used before the summer period and before the winter one. On the other hand, fertilizers with an average dose of Nitrogen, greater quantities of Phosphorus and fewer of Potassium are those used for young specimens of seedlings.
