Estimating solar radiation for water-use and yield simulations under present and projected future climate using Cropsyst.
(2003)Agricultural scientists are faced with the challenge of producing enough food for the increasing world population. Hence the need to develop tools for managing soil and plant systems to increase food production in order ... -
Estimation of reference evaporation and comparison with ET-gage evaporimeter
(2003)Accurate estimation of reference evaporation is necessary for the estimation of actual evaporation for irrigation and water resource management purposes. Estimation of reference evaporati~n using the Penman-Monteith method ... -
Frequency domain reflectometry for irrigation scheduling of cover crops.
(2003)A well-managed irrigation scheduling system needs a rapid, preCIse, simple, costeffective and non-destructive soil water content sensor. The PRl profile probe and Diviner 2000 were used to determine the timing and amount ... -
Heat and energy exchange above different surfaces using surface renewal.
(2008)The demand for the world’s increasingly scarce water supply is rising rapidly, challenging its availability for agriculture and other environmental uses, especially in water scarce countries, such as South Africa, with ... -
Investigating possible impact of climate change on sugarcane production in KwaZulu-Natal, South Africa.
(2016)The KwaZulu-Natal Department of Agriculture, Environmental Affairs and Rural Development in 2010 undertook to investigate the vulnerability of KwaZulu-Natal to climate change which identified various sectors of the economy ... -
Investigation of microclimate for human comfort in the environment and in a car parked in the open.
(2016)Abstract available in PDF file. -
Irrigation control system with a web-based interface for the management of Eucalyptus planting stock.
(2015)Commercial forestry nurseries use large quantities of water to irrigate the planting stock to meet the annual forestry industry planting demands. However, South Africa is a water scarce country and there is high competition ... -
The long-term measurement of total evaporation over Acacia mearnsii using large aperture scintillometry
(2007)A large aperture scintillometer (LAS) was operated continuously over a distance of 575 m from 19 August 2006 to 29 September 2007 in the South African KwaZulu-Natal midlands mistbelt area over Wattle (Acacia mearnsii). The ... -
Long-term measurements of spatially-averaged sensible heat flux for a mixed grassland community, using surface layer scintillometry.
(2007)Evapotransipration by vegetation cover is an important component of the water budget and energy balance in any ecosystem. A key to more improved water management therefore lies in improving our understanding of ... -
Measurement of water potential using thermocouple hygrometers.
(1982)Theory predicts that the time dependent voltage curve of a thermocouple psychrometer where there is no change in output voltage with time during the evaporation cycle defines the wet bulb temperature T[w] corresponding ... -
Microclimate modification to improve productivity of ‘Carmen®-Hass’ avocado orchards using shadenet under subtropical conditions of Limpopo Province, South Africa.
(2016)The agricultural environment is a complex and dynamic system. Microclimate, the crop, biosphere, and management practices interact to determine the best yield production. South Africa is a water-scarce country, with high ... -
Modeling variety differences in canopy growth and development of sugarcane (Saccharum officinarum L.) using Canegro.
(2003)Crop models have great potential as research tools, for crop system management and policy analysis. One of the most promising future uses of crop models is in crop improvement. The limitation in the use of models for crop ... -
Modelling the impacts of increased air temperature on maize yields in selected areas of the South African highveld using the cropsyst model.
(2014)Abstract available in PDF file. -
Modelling the soil water balance and applications using a decision support system (DSSAT v3.5).
(2003)Water is a scarce resource used by various stakeholders. Agriculture is one of the users of this resource especially for growing plants. Plants need to take up carbon dioxide to prepare their own food. For this purpose ... -
Monitoring fire danger in near real-time using field-based agrometeorological measurement systems.
(2014)Africa has been termed the ‘Fire Continent’ due to its high annual fire frequency. Wildfires are considered one of the most common disasters in South Africa resulting in a high number of human fatalities and financial loss ... -
Potential for using trees to limit the ingress of water into mine workings : a comparison of total evaporation and soil water relations for eucalyptus and grassland .
(2003)Current mining methods used to extract coal from underground mine workings disturb the natural environment and the existing stable geological structures. As a result, the ingress of water into the mines increases and the ... -
The radiation balance of Midmar Dam in KwaZulu-Natal, South Africa.
(2016)Abstract available in PDF file. -
Rainy season characteristics with reference to maize production for the Luvuvhu river catchment, Limpopo Province, South Africa.
(2017)In arid and semi-arid regions, crop yields are mainly dependent on the amount and spatio-temporal distribution of rainfall. For most smallholder farmers in rural areas of southern Africa, rainfall is a critical input to ... -
The respiratory health effects associated with particulate matter (PM₂․₅) exposure in children residing near a landfill site : a case of eThekwini Municipality.
(2015)Currently, land-filling is the main waste disposal method utilized in South Africa. However little is known about the health risk factors among children living near the landfill sites. This is a first study that sought to ... -
Runoff simulation using the SWAT model for flood frequency analysis and design flood estimations in the Luvuvhu River catchment, South Africa.
