Today there is an unprecedented amount of data available on weather and agriculture. However, the question remains whether this data helps farmers make more informed decisions.
Janet Lowles, Marketing Manager at InteliGro, believes that the benefit of data only manifests when it is transformed into practical insights applicable at critical moments—whether it is planting, choosing a variety, combating diseases, plant nutrition, or managing specific weather events.
Lowles, who spoke at the launch event for Pessl Instruments' project to install one hundred thousand weather stations in Africa, believes that farmers and companies have not yet unlocked the full potential of meteorological data. She emphasized that the data itself does not reduce risks; rather, improving the decision-making process does. Since a farmer cannot control the weather, climate, resource or commodity prices, they can only control how decisions are made regarding these factors.
In Lowles' opinion, to respond long-term to extreme climatic conditions and smaller changes within them, all available tools must be used. She notes that in the data industry, there is an increasing need to provide information in the form of reliable analytics. This includes turning data access into a practical tool for the farm that provides actionable recommendations, such as a clear indication of whether to spray the plant and why.
Furthermore, she insists on the need for closer cooperation between various resource providers and industry organizations. When industry bodies, universities, and farmers work more cohesively and reliably, this information becomes accessible to everyone.
Dr. Ilse Trautmann, a data-driven farming expert and member of the advisory board for the Pessl Instruments weather station project, asserts that a more resilient agricultural sector begins with an informed approach to decision-making. She highlighted the growing importance of the ability to timely convert necessary information into a decision, especially under conditions of climate uncertainty, drought, and El Niño, which limit maneuverability. Trautmann added that data alone is not enough—people are needed to help in its understanding and application.
The message from Lowles and Trautmann is particularly relevant to dryland and legume farming, where one decision can determine the difference between profit and loss. Agronomist Reinhard Vessels, Technical Marketing Specialist at InteliGro, presented the results of wheat trials by Intelekt Solutions near Murrisburg as an example of how local research can improve farm decision-making.
The trials in Murrisburg began nine years ago and are part of long-term scientific field tests in the Western Cape. The current configuration compares five wheat varieties, five fungicide programs, and an untreated control across 130 plots. Vessels noted that past experience provides data and lessons that can be used in the future, and the value of historical data lies in helping to consider prospects beyond the current season.
Another example was presented at the Swartland exhibition, where soil scientist Jan van Zyl, Technical Marketing Specialist at InteliGro for plant nutrition, explained how soil conditions and local research influence management decisions. His discussion of chemical stratification in minimum tillage systems highlighted the importance of soil samples and a deep understanding of soil profiles. He reported that in some Swartland soils, calcium, potassium, and phosphate can accumulate in the top 2.5 cm, which, according to studies, occurs in about 30% of Swartland soils.
Dr. Karen Truter, Technical Marketing Specialist at InteliGro for plant nutrition, demonstrated the differences that can be observed on a single farm within a day of information. She emphasized that targeted farm trials help farmers determine what works in their specific conditions. The goal is not necessarily to achieve the highest agronomic yield, but to find the best economic return. Truter concluded that this requires a different way of thinking: the question is not only how much crop the crop can yield, but also how much it costs to achieve that yield and what ultimately remains with the farmer.
