Less intensive works best for agricultural soil

    The less intensively you manage the soil, the better the soil can function. Such as not ploughing as often or using more grass-clover mixtures as cover crops. These are the conclusions from a research team led by the Netherlands Institute of Ecology (NIOO-KNAW). Surprisingly, it applies to both conventional and organic farming. These important insights for making agriculture more sustainable are published in the scientific journal Science today. ‘It offers clear evidence to help farmers manage soils better.’

    Growing food more sustainably: what's the best way to do this? It is one of the big challenges: producing enough food without compromising the soil. After all, healthy soil has many functions - called multifunctionality - and for sustainable agriculture these must be preserved.

    ‘A multifunctional soil is essential for sustainable food production, because plants get their food from it,’ state the researchers from NIOO and Wageningen University & Research (the Netherlands), and the Universität Tübingen (Germany). ‘Soil also has indispensable roles in water storage, coping with climate change and disease suppression.’

    Organic vs conventional

    Research on farms across the Netherlands now shows that it is mainly the intensity of tillage that determines whether the soil can retain all its functions. Interestingly, the difference between conventional and organic farming has less of an influence. In both types of agricultural systems, a lot of variation is found in soil tillage and management.

    ‘The good news is that in conventional agriculture, which is the vast majority, there is a lot to gain,’ states soil ecologist and NIOO professor Wim van der Putten. ‘On all farms, including organic ones, it is important at this point not to cultivate the soil too intensively. For example: ploughing less. Inverting the soil during ploughing is a very big disruption for soil life.’
