Vaidyanathan L V and Nye P H 1966 The measurement and mechanism of ion diffusion in soils. Potassium stimulates leaf protein synthe-sis. Behavior in the soil Both phosphorus and potassium are immobile in the soil, meaning they don't move readily with water. When phosphorus fertilizer is applied to the soil it precipitates with elements like aluminum in acidic soils and calcium in soils with pH higher than 7.0. In some cases, the element is in adequate levels, but unavailable due to pH being too high or too low or the soil temperature being too low for adequate uptake. 134.

Limiting soil moisture. Soil Sci. Many sand-based soils with high leaching potential are often low in highly soluble nutrients. Soil K mobility increased significantly with soil moisture content (θv) and there was a positive curvilinear relationship between θv and effective diffusion coefficient (De), suggesting that more K+ can diffuse to the plant roots at sufficient soil moistures.

Part 1, Monograph No. The amount of potassium in a soil may be as much as 80,000 lb per acre-foot, of which only 150 lb is available for plant growth. Tax calculation will be finalised during checkout. Google Scholar. It is extremely mobile and can be lost to leaching, which is downward movement of water through the soil … The effects of lime and potassium chloride (KCl) addition on the vertical movement of potassium (K), calcium (Ca), and magnesium (Mg) were investigated in two Brazilian soils. - K inflow per unit of root surface increased with soil moisture.

Also ensure that … Potassium fixation by the soil showed a biphasic pattern under the W–D regime, with a rapid fixation within the first 2 d after re-wetting, followed by a slower fixation. 86, 263–268. Aust. For each sample, 5g of soil was equilibrated with 50 ml of 0.01 M CaCl2, amended with different K concentrations, and incubated for 24 h at 298 Kelvin. In order to relate K mobility in soil to the availability of K for plant uptake, onion plants were grown in special containers under constant water content in the range of 0.1 to 0.4 cm3 H2O cm−3 of soil.

The supernatant was filtered, and K, Ca, and Mg were determined. Colloq. It is therefore assumed that the water content of the soil influences the rate of potassium uptake by its effect on the transport of potassium from the soil to the root surface. J. 3, 113–164. Potassium does not enter 137, 147–158. Shaviv A, Mohsin M, Pratt P E and Mattigod S V 1985 Potassium fixation characteristics of five Southern California soils. Potassium occurs on the exchange complex of soils especially clayey soils. Am. Potassium is most available to plants when the soil has a pH of 6.5-7.5 but provided it's between 6 and 8, most plants should be able to obtain sufficient amounts of potassium. Am. Potassium is essential at almost every step of the protein synthesis. Activity of the enzyme glutamine synthe-tase in wheat is lower when K is deficient.
