Yara's nitrogen fertilizer products can help boost crop yield
Main content
Of the major nutrients, nitrogen (N) is often required in the greatest quantity by crops, primarily for vigor and yield. Nitrogen plays a key role in chlorophyll production and protein synthesis. Chlorophyll is the green plant pigment responsible for photosynthesis. When nitrogen is deficient, plants develop yellow or pale leaves and their growth is stunted.
Phosphorus (P), is a vital component of adenosine triphosphate (ATP) which supplies the energy for many processes in the plant. Phosphorus rarely produces spectacular growth responses, but is fundamental to the successful development of all crops. For example, maize or other corn crops that lack phosphorus during the growing season achieve lower yields.
Potassium (K) is needed by virtually all crops and often in higher rates than nitrogen. Potassium regulates the plant’s water content and expansion. It is key to achieving good yield and quality in cotton and critical for increasing the size, juice content and sweetness of fruit.

The golden rule in fertilizer use remains simple: Apply the right amount of nitrogen at the right time. Fertilizers with a reliable nitrogen release profile and precise application characteristics reduce losses and enhance plant uptake. In European conditions, but also in many areas and worldwide, CAN and AN have proven to be more efficient than urea and UAN.
