Calcium-Ammonium Selectivity of Two Benchmark Soils from Botswana as Assessed by Competing Semi-empirical Ion Exchange Equations
(Taylor & Francis, 2015)The effectiveness of lime-ammonium-nitrate (LAN) as a nitrogen (N) fertilizer in weathered soils depends on the respective selectivity for ammonium (NH4) and calcium (Ca) by the soils. The study assessed Ca2+/NH4+ exchange ... -
Potassium→ammonium exchange of two benchmark soils from Botswana and its implication for nitrogen economy of the soils
(Taylor & Francis, 2014)Ion exchange preferences for NH4+ and K+ by soil exchanger surface can greatly affect the NO3− leaching into groundwater and nitrogen-use efficiency in agricultural production. Since NH4+ and K+ salts are usually applied ...
