POTASSIUM’S ROLE IN PLANT NUTRITION
symbol: K; available to plants as the ion K+
- Unlike N and P, K does not form any vital organic compounds in the plant. However, the presence of K is vital for plant growth because K is known to be an enzyme activator that promotes metabolism.
- K assists in regulating the plant’s use of water by controlling the opening and closing of leaf stomates, where water is released to cool the plant.
- In photosynthesis, K has the role of maintaining the balance of electrical charges at the site of ATP production.
- K promotes the translocation of photosythates (sugars) for plant growth or storage in fruits or roots.
- Through its role assisting ATP production, K is involved in protein synthesis.
- K has been shown to improve disease resistance in plants, improve the size of grains and seeds, and improve the quality of fruits and vegetables.
Potassium decreases the susceptibility of host plants up to the optimal level for growth: beyond this point, there is no further increase in resistance which can be achieved by increasing the supply of K and its contents in plants.
The high susceptibility of the K-deficient plant to parasitic disease is due to the metabolic functions of K in plant physiology. Under K deficiency synthesis of high-molecular- weight compounds (proteins, starch and cellulose) is impaired and there is accumulation of low-molecular-weight organic compounds. Also, K may promote the development of thicker outer walls in epidermal cells, thus preventing disease attack. K can also influence plant metabolism, as K-deficient plants have impaired protein synthesis and accumulate simple N compounds such as amides which are used by invading plant pathogens. Tissue hardening and stomatal opening patterns are closely related to infestation intensity. In addition, the balance between N and K affects disease susceptibility of plants.
Application of K can decrease helminthosporium leaf blight severity and increase grain yields in wheat. It has been shown that K fertilization can reduce the intensity of several infectious diseases of obligate and facultative parasites.
It has been frequently observed that K reduces the incidence of various diseases such as bacterial leaf blight, sheath blight, stem rot, sesamum leaf spot in rice, black rust in wheat, sugary disease in sorghum, bacterial leaf blight in cot- ton, cercospora leaf spot in cassava, tikka leaf spot in peanut, red rust in tea, cercospora leaf spot in mungbean and seedling rot caused by Rhizoctonia solani
The potassium cycle
Buneba K optimizes the plant absortion of potassium reducing potassium losses in the environment and reducing other sources of edaphic potassium. It can be used effectively to improve bud and fruit retention.
Potassium is released into the soil solution from clay minerals. The quantities and rates of release depend on the soil mineralogy, rainfall, and temperature, and can also be influenced by crop management.
Inorganic fertilizer K is sold in various formulations including liquid, granular, and slow-release. Relatively small amounts of K become available from decomposition of manures and crop residues.
Since plants take up large amounts of K, its removal in harvested crops can be significant. Leaching of K can occur, particularly in coarse-textured soils, if fertilizers and irrigation water are applied carelessly. K losses with eroded soil are not usually serious and can be minimized with good soil management practices.
Under conditions where K has been severely depleted from the soil minerals, K fixation can occur. K can be fixed in the structural lattices of 2:1 clay minerals, such as illite and vermiculite. Fixed K is not readily available to plants, but may be gradually released for plant uptake.
