Na improves the growth of K-deficient but not K-sufficient kale
(2022-02-15)
The decrease in the use of K fertilizers may be relevant for developing countries that depend on imports, as well as for specific groups such as patients with chronic kidney disease, who have restricted K in their diets. ...
An unusual pattern of Na+ and K+ movements across the horse erythrocyte membrane
(1986)
Marked differences in the activities of three monovalent cation transport systems in horse versus human erythrocytes are reported. Whereas horse erythrocytes exhibit a 6-fold higher sodium-lithium countertransport, the ...
Dinâmica do potássio no solo e nutrição potássica da soja
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 1993-09-01)
Potassium deficiency in soybeans has spread iii São Paulo State, Brazil, as a consequence of soil K reserve depletion. Exchangeable and nonexchangeable K dynamics in soil were investigated in order to understand the reserve ...

Photosynthetic and anatomical responses of Eucalyptus grandis leaves to potassium and sodium supply in a field experiment
(2013-06-13)
Although vast areas in tropical regions have weathered soils with low potassium (K) levels, little is known about the effects of K supply on the photosynthetic physiology of trees. This study assessed the effects of K and ...

Lixiviação de potássio em função da textura e da disponibilidade do nutriente no solo
(Sociedade Brasileira de Ciência do Solo, 2008-12-01)
O manejo correto da adubação potássica pode minimizar perdas assim como evitar o esgotamento de K do solo. Objetivou-se estudar a dinâmica do K no perfil do solo em função do teor de argila e do teor do nutriente resultantes ...
