Most of the irrigation systems they use are available here, but with the flood of systems available on the market, it is often difficult to choose the one most suited to your farming environment. Stockfarm spoke to a few experts in the field to find out what the options are.
Different irrigation systems
Francois Griesel of Valley Irrigation says there are many factors to consider before deciding on the right irrigation system. He divides the different irrigation systems into centre pivot, drip irrigation, micro-sprinklers, permanent sprayers on fields, quick coupling systems, cannon sprinklers, and flood and channel systems.
The factors that will influence the choice of system include the crops planted and the type of soil. “The help of an expert is needed to decide on the correct crop and cultivar for the specific soil/water combination. This will include information on planting direction, spacing, seed density, cultivation practices, water demand and climate control,” says Francois.
He also believes it is useful to conduct a thorough soil analysis that will highlight the texture, infiltration rate, water-holding capacity, depth and permeability.
Factors to consider
Gerhard Grobler of Water Pleasure agrees. However, he adds that several other factors must also be considered.
The availability of water, among other things, is paramount. According to Gerhard, it is advisable to first contact the Department of Water and Sanitation to gather information on the water source you wish to use as well as the legal aspects relating to water consumption, such as the amount of water that can be extracted during different times of the year and the maximum amount that can be stored.

Shongololo Boer Goat Stud: Only The Best Will Do
South African Boer goats have proven popular worldwide for their ability to improve indigenous goat breeds. In addition, Covid-19 restrictions necessitated the establishment of electronic auctions, making it easier for foreigners to acquire outstanding genetic material exported by agents via established channels.
Feed Additives: A Veterinary Perspective
In an already volatile environment, dairy profit margins vary as milk prices and feed costs shift annually. Feed costs represent the largest input cost (an estimated 35 to 70% of the variable cost) in the production of milk. As a group of feed ingredients, feed additives can cause a desired physiological response in a non-nutrient way, such as pH shift, growth or metabolic modifier, and will usually be cost-beneficial.
Guard Against Lumpy Skin Disease
Most parts of the country received good rains during the rain season and producers are generally very optimistic. Wet seasons unfortunately come with their own set of challenges and veterinarians have cautioned livestock producers to keep an eye out for elevated biting insect loads, which may lead to conditions such as lumpy skin disease (LSD).
Climate-Related Hazards: How Smallholders Can Mitigate Its Consequences
Rainfed crop production remains the main source of food security and livelihoods for rural communities in South Africa but presents the challenge of climate variability due to its high dependence on weather variables such as rainfall and temperature.
Tips for a successful AI programme
The success of an artificial insemination (AI) programme depends on several factors that are largely within the control of the producer. It is interesting that those producers who take a hands-on approach to their cattle and inspect them regularly are also the ones who achieve the greatest success. Before his passing, Stockfarm spoke to Koot Louw, a well-known reproduction technologist from Brandfort in the Free State, about his insights into and advice regarding the AI process.
Pay Attention To Orf In Your Flocks

Sanele Mbele: Where Passion And Skill Meet
Passion for farming runs strong in the Mbele family’s veins. Sanele Mbele, from the farm Rietspruit in the De Jagersdrift area near Dundee, has inherited this passion in huge dollops.
Land Reform: Case Studies In Kwazulu-Natal
Land reform in South Africa is complex. Land reform solutions are equally complex and within partnership and development models, this is no different – but there is hope. KwaZulu-Natal has several types of partnership models and the wide variation in farming systems, as well as their different needs, set each model up for different strengths and weaknesses.
Brahman Breeders In Limpopo Have A Winning Plan
Several breeders from the Bosveld Brahman Club in Limpopo are applying genetic excellence and genotypic correctness to stimulate the demand for their bulls. At several of the last auctions, the minimum standard of bulls was raised to achieve this goal.
A Brahman Dream Comes True
For as long as he can remember, JP Mlangeni wanted to be a farmer. It might have taken a few years, from being a teacher and later a businessman, but his dream finally took shape and today he runs a fully-fledged breeding and commercial Brahman farming enterprise in Mpumalanga.
