Fijación de potasio y competencia con amonio en una arcilla expansiva

Abstract: En Venezuela existen amplias zonas en donde predominan suelos con arcillas de tipo 2.1 con capacidad para retener iones potasio y amonio en el complejo interlaminar. Como los iones K+ y NH4+ presentan el mismo estado de oxidación (valencia), al igual que similar radio iónico, ambos iones pueden competir en estas arcillas expansivas por los sitios fijos de adsorción, y uno de ellos disminuir la capacidad de fijación del otro. Estudios realizados en suelos de los Valles del Tuy, estado Miranda, señalan el predom… Show more

“…However, using K fertilizers such as potassium chloride, potassium nitrate, monopotassium phosphate, and sulfate potash can resulted in various issues such as reduced soil fertility, disruption of biochemical energy flow, formation of complex compounds, and higher levels of salinity and soil acidity (Olaniyan et al 2022). Another issue is that K can be trapped in clay minerals soil while competing with ammonium (Hernández et al 2021). Vermiculite and micaceous are types of clay minerals that function as a reservoir for K, as they have a solid attraction for K ions and can retain them effectively (Dubus et al 2023).…”
