It is often assumed that implementing no-till production is the immediate next step towards restoring degraded soils. Not so, says Guy Thibaud, a veteran soil scientist with the KwaZulu-Natal Department of Agriculture and Rural Development.

Plant parasitic nematodes pose a serious threat to food security in Africa as they damage crops and hamper production. Dr Nancy Ntidi, a nematologist at the Agricultural Research Council, spoke to Annelie Coleman about the effects these pests have on African leafy vegetables, and how they can be effectively managed.

The availability of improved varieties, mandate contracts and storage infrastructure promise to turn barley into a lucrative option in the Swartland. Gert Claassen, who five years ago started producing barley on a commercial scale, spoke to Glenneis Kriel about this opportunity.

Before planting a land to any of the cucurbits, you should kill off all broad-leaved weeds nearby, preferably well beforehand.

Cotton production in North West can be extremely lucrative, according to Arno Janse van Vuuren, manager of agricultural management at agribusiness NWK. A comprehensive survey by the company shows that the province is well suited to cotton cultivation if production is managed effectively.

A unique microclimate in the southern Eastern Cape has given rise to a niche cropping industry that requires intensive precision production over a five- to seven-year cycle. Sabrina Dean paid a visit to large pineapple producer Mark Harris to find out more.

The establishment of an almond-processing facility in Robertson has the potential to turn South Africa into a leading exporter of these nuts. Stephan and Hans le Roux of Amanteco Almonds spoke to Glenneis Kriel about the opportunities and pitfalls associated with this crop.

By switching from micro-irrigation to low-flow drip irrigation, macadamia farmer Dawid de Kock has reduced his irrigation water usage by 50%. With the subsequent savings on electricity, fertiliser and labour, the system has significantly improved his bottom line.

Many people who enjoy lettuce in their salad may not be aware that it can be a fairly challenging crop to grow commercially. Dicky and Koshik Sitaram, whose family have been producing fresh produce for many years in KwaZulu-Natal, shared the lessons they learned with Lloyd Phillips.

Some growers in the Southern Cape are using nets that can easily be draped over tree rows to protect pome fruit against sunburn. Apart from their convenience and flexibility, the new nets cost a fraction of fixed net structures. Daan Brink of Two-a-Day and Ebbie Raubenheimer of Nulandis spoke to Glenneis Kriel about the technology, which was developed in Australia.

Researchers have estimated that, over the past four decades, the world has lost a third of its arable land due to erosion or pollution. Solutions are constantly being sought. Frans Joseph and Mias van der Westhuizen of the Free State Department of Agriculture and Rural Development recently tested the mitigating effect of a simple, inexpensive method to address soil erosion.

Viking Farming near East London in the Eastern Cape is a small but intensive vegetable operation that supplies supermarkets and processors across the Eastern Cape and even the Western Cape. Mike Burgess visited Valhalla farm to better understand how owner Mike Pedersen-Horn has managed to build up this adaptable and profitable business over the past 20 years.

Up-and-coming commercial farmer Daniel Maqala is diversifying further by investing in asparagus. Sabrina Dean visited him to find out more about his journey so far.

With no-till farming, you need to try to gradually increase the organic content of the soil.

Efficient in-field mechanisation is a major contributor to higher yield and lower production costs. Unfortunately, mechanisation also means that machinery wheels regularly compact the soil. According to precision farming specialist Ian Beecher-Jones, traffic-induced soil damage can be limited by implementing controlled traffic farming.

Company representatives often bombard farmers with products claimed to increase yield at little cost.

Poland is the largest producer of apples in the European Union. On a recent visit to the country, Annelie Coleman met Bartłomiej Brodzik from the Apple Factory, one of Poland’s major apple growers and exporters.

Leafroll virus is a serious threat to South Africa’s viticulture industry: it shortens the lifespan of vineyards and has a negative impact on wine quality.

When the soil contains sufficient organic material, farming becomes far easier and less risky. In contrast, in a chemically based system, the interaction between the minerals becomes critical and complex, and a farmer needs a great deal of experience and knowledge to get good results.

Johan Jacobs plants lucerne to ensure mega yields from other crops in his niche farming business, as well as a good cash flow for at least nine months of the year. Sabrina Dean visited him on his farm on the banks of the Orange River in the Northern Cape.
