How to maintain a good vegetative growth: NPK Liquid

Crops need to absorb nutrients that can be mostly taken from the soil. However, it is sometimes needed to add nutrients as the plant could suffer from deficiencies.


Plants rely on the absorption of primary macronutrients such as nitrogen (N), phosphorus (K) or potassium (P) to grow and to be maintained in a proper way. Such is the importance of these macronutrients that we must be sure that our plantation does not present deficiencies if we want it to have in good health conditions.


Each nutrient provides specific benefits to the plant, in this way, we can see if our crops need some extra nutrients:

-Nitrogen deficiency.This nutrient provides vigor to plants as well as aiding the development and maintenance of their leaves. Therefore, when the crop has a lack of this mineral, it can be observed that the leaves appear clearer, almost yellow. In addition, this deficiency is first detected in the older (lower) leaves, which will fall off if the crop is not treated. 

-Phosphorus deficiency. As in the case of Nitrogen, the lack of this mineral can be observed earlier in the older leaves. When the phosphorus is insufficient, the leaves show a dark green which then turns into a reddish color. In this case the number of shoots decreases and the plant could become dry if it is not treated.

-Potassium deficiency. If the deficiency is severe, it can be observed in young shoots, which are severely affected. The overall development of the plant is affected, from souring to ripening.


In Vellsam, we have developed specific products for treating this problems.
