Cover crops can improve soil and crop health, says Agricol's KZN sales manager and agronomist Dustin Beckerling, who gives Lloyd Phillips some pointers on selecting appropriate cover crops.

Dairy farmers wanting to increase the number of calves and the percentage of heifers born on their farms should consider in-vitro fertilisation as opposed to artificial insemination, reports Alan Harman.

The US agriculture department now also feeds impoverished school children during the holidays. Roelof Bezuidenhout discusses what South Africa is doing for its 14 million hungry citizens.

Researchers have found that termite mound size and distribution, linked to vegetation and landscape patterns, can predict ecological shifts, writes Alan Harman.

Harvesting mistletoe is one of the most cost-effective drought survival measures available to stock farmers, writes Roelof Bezuidenhout.

Mascor held its John Deere demonstration on Masonite's Mount Desire farm, attracting almost 100 farmers, many from the Wartburg/Dalton area. Proceedings opened with an address by Prof Peter Lynne from the Sugar Research Institute.

A new trial found that camels could help control and possibly eradicate sweet thorn encroachment, which may be a far better solution than Boer Goat browsing or fire control.

Current research into caracal control, conducted on nature reserves or game reserves, isn't always the best measure of effectiveness on a farm. A new study, conducted under practical farming conditions, aims to find the best solutions for small-stock farmers.

Satellite images could soon be used in South Africa to quantify veld production, estimate livestock carrying capacity and help farmers plan fodder flow, reports Roelof Bezuidenhout.

The sugar industry is under pressure to reduce cane burning before harvesting – creating new possibilities for cane residue to cogenerate electricity. Joe Spencer reports.

When it comes to predator management, South African agricultural and environmental authorities look more like the farmer's foe than friend in comparison with the US's wildlife service.

Numbers of large mammals are dropping in national parks all over Africa - except in the continent's southern countries, where good management shows what can be achieved.

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.

The annual Boerepatente Kompetisie always showcases great ideas to improve and simplify the farming experience, including devices to conquer load shedding and the dangers it brings. Joe Spencer reports.

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.

German company Krone began making forage harvesters in 1977, selling 5 000 “Corn Chopper” tractor mounted units. In the 1980s Krone introduced its first self-propelled harvesters. The latest range of Big X models includes monsters powered by twin engines with up to 750kW of power. Krone harvesters imported into South Africa by Rovic and Leers come with the new EasyCollect 753 maize header.
