NPK Fertiliser

NPK fertiliser, meaning and uses in agriculture

NPK fertiliser is the most widely used fertiliser in agriculture. It is in fact a mixture that contains the three main elements needed by plants to grow.

It contains nitrogen (N), phosphorus (P) and potassium K), the three macro-nutrients that plants need to grow healthy and productive.Each of these elements has its own specific role in plant metabolism, but all three are essential.

Nitrogen (N)

It makes up 78% of the atmosphere and is essential for plant growth as it is the basis for plant cell construction and chlorophyll. It is considered the basic element for productive agriculture and for this reason it usually represents the highest percentage in NPK fertilisers.


Phosphorus (P)

The second component of NPK fertilisers and is essential for root development, photosynthesis, energy transport, and also in flowering and fruiting. Phosphorus deficiencies lead to stunted plant growth and increased vulnerability to insects and diseases.


Potassium (K)

The third element in the NPK triad. Although it does not serve to build plant tissue, it is essential for regulating plant metabolism. Potassium deficiencies lead to leaf necrosis, stunted growth and plant weakness.

The use of NPK

Before purchasing an NPK fertiliser it would be a good idea to consult a technician for advice on the best product to purchase. It should also be considered that NPK fertilisers are often sold with added trace elements, such as calcium, zinc, sulphur, iron or boron. In this way, a more complete and balanced nutrition can be provided..

When you are preparing to fertilise your field, you must always have a strategy that translates into a fertilisation recipe, which describes the type of fertiliser to be used, the dose, the time of use and the needs of the crop.

The fertilisation recipe is influenced by the type of soil, the macro-nutrients removed from the previous crop, those immobilised or dispersed in the past year, the crop being fertilised, its phenological stage and the farm's objectives. These calculations are not always easy. To avoid problems of under- or over-dosing, or inefficient wastage of resources, it is always a good idea to consult a technician..
