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 ...

Sorghum yield and associated satellite-derived meteorological parameters in semi-arid Botswana
(African Crop Science Journal, 2015-03-15)
Africa has sparse meteorological stations, hence it is increasingly common to use satellite-derived meteorological parameters, where in-situ measuremnts are not available. The objective of this study was to determine if ...
Evaluating different soil tillage surface conditions on their rainwater harvesting potential in Botswana
(African Journal of Rural Development (AFJRD), 2015-10-03)
Rain water harvesting (RWH) is described as concentration, collection, storage and use of rain fall via runoff for various purposes such as domestic, livestock and agricultural use. RWH systems can be classified as macro, ...
An assessment of socio-economic potential for Rain Water Harvesting (RWH) in semi-arid Bobirwa Sub-district of Eastern Botswana
(African Journal of Rural Development (AFJRD), 2015-10-02)
This study assessed the socio-economic potential of the Rain Water Harvesting (RWH) techniques for crop production in the semi-arid area of Bobirwa Sub-district, Botswana. The main methods used to collect the data were the ...
