Researchers at the XIX International Colloquium on Soil Zoology, held recently in Cape Town, highlighted the impact of agricultural production practices on soil diversity.
Guénola Pérès, an assistant professor at the Institut Agro Rennes-Angers in France, said many studies had analysed the impact of reduced mechanical soil disturbance, cover crops, crop rotation and organic matter management, but most of these focused on the impact on isolated soil properties, such as soil chemistry, biology and physiology.
The SoilMan project in Europe, co-constructed by researchers and farmers, aims to provide a comprehensive understanding of how various soil properties interact and influence soil quality, health and sustainability.
One of the project's studies, on 12 fields managed by farmers in Britany, France, compared the impact of a wheat and maize rotation system, ploughed 25cm deep with a mouldboard, to a conservation farming system in which maize and canola were rotated with two grain crops, using direct seeding.
Mineral fertiliser was used in the first treatment, and mineral and organic fertiliser in the second.
No significant difference was found between wheat yields, but the study revealed that the conservation farming practices had a positive impact on earthworm abundance, biomass and diversity, as well as anecic earthworm abundance.

Global outlook for wheat in 2024/25
In its latest estimate, the International Grains Council has adjusted global wheat production for the coming season due to poorer-than-expected harvests in the EU. However, global supplies remain strong, while global consumption is expected to increase to reach about 804 million tons. Janine Ryan reports.
From fallow land to award-winning wines: the Newstead story

Fact file of fungal diseases in wheat
Wheat is a significant crop, and like other crops, is susceptible to a range of infections. Here, we provide information on the most important fungal diseases that affect wheat.
Soil preparation for wheat and other cereals
For seed to germinate and plants to grow, soil often needs to be prepared. The manner in which it is done depends on the type of soil, the organic matter and moisture it contains, the crop to be planted, as well as the previous crop that was planted in the field. Magda du Toit spoke to cereal experts and farmers for guidance.
