Integrating rainfall runoff and evaporation models for estimating soil water storage during fallow under in-field rainwater harvesting
(University of the Free State, 2014-07-18)
English: In-field rainwater harvesting (IRWH) is a beneficial water conservation practice. Fallowing is an important strategy to enhance water conservation. Fallowing consists of a period where no crops are grown (bare) ...
Evaluation of maize and sunflower production in a semi-arid area using in-field rainwater harvesting
(University of the Free State, 2006-11)
English: Subsistence farmers occupy a large area east of Bloemfontein around Thaba Nchu in the Free State Province of South Africa. They do not enjoy food security because the area is marginal for crop production. There ...
Quantifying evaporation and transpiration in field lysimeters using the soil water balance
(University of the Free State, 2010-05)
The main aim of this study was to determine the transpiration efficiency coefficient (TEC) for three C3 crops; canola, wheat and lucerne. TEC relates to the efficiency of water management in crop production. It is defined ...
Soil surface evaporation studies on the Glen/Bonheim ecotope
(University of the Free State, 2010-11)
The biggest challenge in semi-arid areas is finding ways of reducing the major unproductive water loss: evaporation from the soil surface. A large number of subsistence farmers east of Bloemfontein, in and around Thaba’Nchu ...
