Sugarcane is a major land use in KwaZulu-Natal and Mpumalanga and competes with other crops, as well as industrial and domestic water users, for water resources. Approximately 420 000 ha is currently under sugarcane in South Africa, of which approximately 21% is irrigated, primarily supplying the northern mills of Malelane, Komati, Pongola, Umfolosi and Felixton. In the northern areas where ann...

Limited water resources in arid and semi-arid regions are one of the major limiting factors in agricultural production. Thus, unconventional water resources, such as urban and industrial treated wastewater, may be used for irrigation. Application of wastewater to soil may cause accumulation of heavy metals (HMs). Soil pollution causes uptake of these metals by plants and their entrance to food ...

The evaporation and the thermal accommodation coefficients for water in nitrogen were investigated by means of the analysis of evaporation of pure water droplet as a function of temperature. The droplet was levitated in an electrodynamic trap placed in a climatic chamber. The levitation time was in the range of seconds, which corresponds to the characteristic time scales of cloud droplet growth...
