Farming for Tomorrow

Bitter bush veld is a sign of overgrazing and veld degradation. Eradicating this invader will allow palatable, perennial grasses to flourish again, writes Roelof Bezuidenhout.

In the Amatola Mountains in the Eastern Cape, Cape parrots are as iconic as the giant yellowwood trees they feed on and nest in. But as Mike Burgess reports, initial fears of a deadly viral disease that had apparently infected Cape parrot populations in the area in 2008 and 2009, is now being confirmed by parrot expert Dr Steve Boyes, who believes the disease can wipe out South Africa’s only endemic parrot.

Physiological improvements in broilers haven’t changed negative consumer perception of the poultry industry. Dr Marc de Beer says the industry has to set the record straight.

Parasites’ growing resistance to anthelmintic remedies is a serious problem for smallstock farming. Field expert Dr Dave Midgley explains that the problem should be tackled through an integrated management system rather than by blanket dosing.

SANBI is starting pilot projects to develop biodiversity in the red meat industry, writes Roelof Bezuidenhout.

The selection of an appropriate base crop is vital for livestock farming on planted pasture. It forms a solid foundation for an ongoing fodder flow to ensure optimal production and profitability. The base crop will also determine additional pasture species that can be planted for the periods when its growth slows down. Jan Coetzer of Pannar explains the importance of appropriate base crops and how to use planted pasture in dairy, beef and sheep farming.

The KZN Department of Agriculture, Environmental Affairs and Rural Development’s Bioresource Programme lays a firm foundation for improved farm decision making, reports Lloyd Phillips.

One of South Africa's largest farming operations, ZZ2, needed dramatic production changes to stay sustainable. They formulated natuurboerdery, which gave them all the benefits of organic farming without a major fall in production. Glenneis Erasmus reports on how this approach is starting to pay off.

Rather than measuring the water content in the soil, Watermark soil water-potential sensors help farmers determine how much water the crop needs, says SASRI researcher Ashiel Jumman. Glenneis Erasmus reports.

Last week, soil scientist Neil Miles discussed the role animals play in the nitrogen fertilisation of pasture. This week, he tells farmers how to get the most out of soil organic matter.

Hydroponic production only really came into existence in the 1930s, making a name for itself during the Second World War when it was used in the Pacific Islands to grow food for soldiers.

'Minute molecules go right to where they're needed, giving impressive results.'

Dung beetles can restore the health of farming ecosystems, reports Cornelia du Plooy. But their survival is threatened by toxic anti-parasitics. A toxicity rating system for animal health products now gives farmers an indication of how to use these products safely.

Farmers who blame the southern springhare for destroying their chicory crops often hunt it as pest. However, a recent study indicates that the springhare is an innocent victim - the damage is more likely to be caused by the common duiker, an antelope that not only injures the leaf stock but also digs into the soil to expose the chicory root.

At a recent course on sustainable farming, Graeme Sait, CEO of Australian company Nutri-Tech Solutions, promoted natural growth stimulants and pesticides such as triacontanol and aloe vera, and more effective integrated pest management.

At a recent course on biological farming, presented by Nutri-Tech Solutions, Wilma den Hartigh found out about valuable tools used to measure soil pH and brix levels, and plant sap extractors for monitoring plant health, as well as why more farmers are using foliar feeds.

Inducing systemic activated resistance is one of the active defense systems that can protect crops against disease attack. Joel Williams said inducing systemic resistance can be effective in achieving quality without sacrificing yield.

Farmers can pick up plant nutrition deficiencies before they become visible in the field by means of a leaf analysis, says Joel Williams.

The “big four” approach Joel Williams said Zimmer's discovery, known as the “big four” approach, focuses on building maximum sugar production and microbe support.

Alongside natural vegetation, insects and small mammals, birds are the most underrated and underdeveloped resource in agricultural tourism on farms and game ranches. With skill and imagination and very little input, this resource can contribute significantly to the income of an enterprise.
