Potassium in cereals promotes starch biosynthesis leading to higher grain weights. Potassium restores the vital crop water balance, regulates stomatal opening to improve photosynthesis which is the key biomass production process in plants. Potassium is also a component of some enzymes that actively participate in photosynthetic reactions leading to biomass production. Potassium must be applied early in the season for root uptake or through the foliage only at later stages of growth, as roots generally do not pick up potassium after flowering/anthesis in cereals. Traditionally, potassium is often ignored in the crop production system; as a result many growers are now experiencing potassium deficiency in their paddocks. Potassium has now been widely recognised as the least available nutrient in soil due to erosion, its excessive mining by roots and non-replenishment back into the soil. As a result the buffer potassium component of soil is not enough to release potassium in top soil for plant absorption in most cropping regions of Australia.
The deficiency symptoms of potassium include
Marginal and leaf tip necrosis due to the enhanced synthesis of polyamines
Poor quality grain and grain size (screenings)
Late season blotchy chlorosis
Poorly developed root system
Plants wilt easily with imposition of marginal water stress
