Soybean seedling emergence under current and future climate across Europe and the possibility for sowing date adaptations

Abstract

Soybean (Glycine max (L.) Merr.) has potential to improve the sustainability of agricultural systems due to several advantages it offers, including its capacity to fix atmospheric nitrogen (Watson et al., 2017). In Europe, this crop is much less reliant on conventional pesticides compared to its leguminous counterparts (e.g. pea). The introduction of this crop into European cropping systems not only offers their diversification but also helps increase the protein self-sufficiency of the continent thereby reducing import dependency (Guilpart et al., 2022). However, little is known to date about i) the areas suitable for soybean emergence and seedling establishment across Europe, ii) how ongoing climate change will affect the distribution of these suitable areas, and iii) the possibility of adaptation of soybean crop by shifting sowing dates. To address these questions, a simulation study was conducted by coupling climate change scenarios (historical: 1981-2010 and RCP 4.5: 2040-2069; (Webber et al., 2018)), machine learning algorithms, a soil-crop model (STICS), and a crop emergence model (SIMPLE). Six sowing dates (from early to late) were considered. Preliminary results showed a significant shift in seedbed climatic conditions across Europe under climate change, especially due to an increased seedbed temperature. For late sowing dates, previously unsuitable areas resulted suitable for soybean establishment, across boreal and northern continental regions, but the opposite was observed across southern Mediterranean areas. In contrast, early sowings show good potential for soybean seedling establishment in Northern France, the southern Mediterranean, Alpine and southern continental regions.
