As we all know, nitrogen, phosphorus and potassium are almost the most needed nutrients in the growth cycle of all crops.It is also the most used fertilizer by our farmers.So what do these elements do during the growing season?What’s the connection?
The main function and relation of n, P and K
Nitrogen is an important component of chlorophyll and is a major component of proteins and enzymes in crops.It can make the leaves healthy and thick, bright color, promote crop photosynthesis, improve crop yield, and further improve crop quality.
Why is nitrogen fertilizer good for leaf growth?
Nitrogen is a component of chlorophyll, which is a nitrogen compound.Green plants use chlorophyll to change light energy into chemical energy and inorganic matter (carbon dioxide and water) into organic matter (glucose) in photosynthesis.Glucose is the raw material that plants use to synthesize various organic compounds, while chlorophyll is the factory that plants use to make food from their leaves.So nitrogen has leaves.In turn, nitrogen deficiency and nitrogen supply can be determined by leaf size and color depth.
Why does phosphorus promote fruit growth?
Phosphorus is essential for the formation of nuclear proteins, lecithin.It can accelerate cell division, accelerate root and aboveground growth, promote flower bud differentiation, early ripening, and improve fruit quality.Phosphorus is mainly involved in photosynthesis, respiration, energy storage and transfer, cell division, cell enlargement and other processes in plants.Secondly, phosphorus plays an important role in the synthesis and decomposition of protein.Phosphorus also promotes fat synthesis.All of these factors are key to healthy fruit growth.The general manifestations of phosphorus deficiency in crops are: slow growth, short stature and emaciation, erect, less branching, poor root development, delayed maturation, and reduced yield and quality.
Why can’t crops lack potash?
Compared with phosphorus, potassium is one of the most mobile elements, mainly in the form of ionic or soluble potassium salts, which exist in the most active organs and tissues.Potassium can promote the utilization of light energy, enhance photosynthesis and promote the movement of photosynthetic products;Potassium is an important quality element and has many effects on improving plant quality.Potassium can also improve plant resistance, promote the development of plant epidermis and vascular tissue, strengthen cell water retention, reduce plant transpiration, and thus enhance plant drought resistance.Potassium can increase the plant body sugar reserve, improve cell osmotic pressure, enhance the cold resistance of plants.At the same time, if the crop is deficient in potassium, it will show: the plant stalk is weak, easy to lodging, drought resistance, cold resistance is reduced, protein and chlorophyll are destroyed, growth is slow, protein is destroyed, crop yield is reduced, and taste is decreased significantly.
It can be seen that the protein and chlorophyll obtained in the case of abundant nitrogen and phosphorus will be destroyed by the lack of potassium, so all three elements are indispensable.
