Tell us about the role of nitrogen, phosphorus and potassium in plant development.

Nitrogen is essential for the growth and development of all parts of the plant. Part of proteins. With a lack of nitrogen in the soil, the growth of shoots slows down, the leaves lose their bright green color and die off over time. With an excess of nitrogen in the soil, the size of the leaves increases abnormally, the shoots grow very quickly, but their tissues are loose, and therefore frost resistance decreases. Slow down ripening.
Phosphorus is included in the composition of protein substances, accelerates the onset of flowering. Promotes the formation of fruits, accelerates the ripening of the crop and ripening. With its lack, violet-red spots appear on foxes.
Potassium increases the resistance of plants to drought, frost and disease, accelerates the process of photosynthesis and promotes the accumulation of carbohydrates.
Promotes accelerated ripening. With a lack of potassium in the soil, the leaves die off the edges, and they themselves acquire a pale color.
