The functions of potassium in plant growth are numerous as potassium influences photosynthesis, respiration, translocation and many enzyme systems. Fertilization with potassium when soils are unable to supply sufficient amounts results in large yield responses. Reduced availability of potassium can lead to a reduction in plant growth and occasionally in crop quality .Response from potassium additions is first observed when the rate of regrowth is more rapid following a harvest. The rapid rate of regrowth allows the alfalfa to compete more aggressively against weeds and insects which results in longer stand life. Increased disease resistance may be another factor that can be attributed to potassium fertilization. Potassium is known to improve the level of carbohydrates stored in alfalfa roots. Greater stand persistence is the result of a combination of these factors. Potassium fertilization increases the potassium content of alfalfa and affects the concentration of other elements. It has been observed in numerous cases that whenever a nutrient addition results in large alfalfa yield increases, many, if not all other element concentrations will be reduced. Research indicates that potassium additions tend to increase protein in only a few cases and a more general result is that protein content is decreased. Potassium additions generally reduce calcium, magnesium, sodium and occasionally some of the micronutrients. Experiments including higher rates of applied potassium show that potassium concentration continues to increase long after any yield increase is observed, clearly indicating "luxury consumption".
