Farming for Tomorrow

Researchers in Argentina believe they have found the ideal stocking rate for an ecological feedlot system, which allows for optimal land use. In winter, the land is used as a feedlot and in summer for crop cultivation.

It’s not too late to restore damaged palmiet wetlands, says Alanna Rebelo of Stellenbosch University’s Department of Conservation and Entomology. Roelof Bezuidenhout spoke to her about the value of these remarkable wetlands.

Ionised gases are being used to kill food pathogens on packaged food. This method could bypass current heat treatment and chemical sanitising methods.

Plants of the brassica family can act as natural biofumigants when chopped up and worked into the soil, says plant pathologist Dr Reinette Gouws of the Agriculture Research Council.

Precision agriculture (PA) allows farmers to operate more efficiently and become better decision-makers. Australian Tim Neale and Sharon Clay from the US took part in a PA conference in Potchefstroom. Annelie Coleman compiled this report.

The use of bees as crop pollinators is well-known, but a group of scientists warns against confusing the European bumblebee with the South African carpenter bee.

Bumblebees have been used worldwide since the mid-80s to deliver pollen to flowers. Now they’ve become ‘flying doctors’. Robyn Joubert reports.

Due to underdeveloped gut microflora and immature immune systems piglets are highly susceptible to pathogenic infections which result in poor performance. To withstand these pathogens, a protective gut microflora and an optimised non-specific immune system are crucial. Feed expert Dr Thomas Volker explains why.

Activated oxygen water treatment trials in North West have shown positive results in wheat and maize yields. Annelie Coleman reports.

Australian research has shown the possibility of eliminating the horn gene in Merino sheep.

Research conducted by HortResearch SA’s Dr Steve Oosthuyse shows that timely pruning of litchi trees can produce a rich flush and yield a greater harvest.

Co-operation between South African and Argentinian agricultural organisations has led to a series of multi-year trials in selected South African localities to compare Argentinian direct planting technology and conventional systems with those used in South Africa. Pietman Botha reviews the first year of the trials, which were launched in 2011.
