Data for: Determinants of yield variation of organic cereals in productive agricultural areas

https://doi.org/10.5878/z95f-6h51
This dataset contains data on yield, crop management, field measurements and field conditions for organic spring barley and winter wheat fields in agricultural areas of southern Sweden from 2020. The data was collected to determine yield limitations for these two crops and the relative importance and relationships between management (for example fertilisation, weeding, soil cultivation, preceding crop, crop rotation, time since conversion to organic farming) and its effects on various measurement of the field state (for example nutrient levels, weed, diseases) as well as soil characteristics and weather. The farms (56 in total) were all organically certified and located within the regions of Skåne, Halland and Västergötland, one field per farm and crop was visited. Field visits were done to take measurements in the field, these included plant nitrogen levels (through SPAD), weeds, pests and diseases measured during the growing season, and soil samples gathered in the end to analyse phosphorus and potassium levels, as well as pH and soil organic matter content. This data was gathered in four 2x2 meter observation plots in each field, and the data present averages across these four plots. After this the farmers were contacted to get information about the field's management operations and yield. Additional contextual data was gathered from landuse, weather and soil maps, averaged for the entire field and/or summed over time. Included in the dataset is both the original data and also values that have been regionally group mean centered, as used in the related publication. The data is split between spring barley (SB) and winter wheat (WW) and each row represents one field, 52 fields with spring barley and 29 with winter wheat.

Population:

Organically managed crop fields of spring barley and winter wheat in agricultural areas of southern Sweden.

Study design:

  • Observational study

Description of study design:

All farms within the studyarea (agricultural parts of Skåne, Halland and Västergötland area) that grew organic spring barley or winter wheat were asked to participate, in total 52 farms were visited. One typical field per farm and crop was selected and within each field 4 observation plots were placed to reflect the variation in soil clay content within the field.

Award title:

Constraints on the expansion of organic farming in Sweden

Funding information:

This project investigates constraints on the uptake of organic farming in Sweden, focussing on understanding reasons for low uptake in highly productive landscapes. To this end we will (1) investigate what factors constrain farmers from converting to organic farming under different conditions, (2) study how challenges resulting in yield losses, e.g. due to nutrient limitations, weed competition and limited pest control, varies with soil conditions, landscape complexity and prevalence of animal husbandry, (3) identify means such as alternative crop rotations and products, and promotion of yield-enhancing ecosystem services, to upscale organic farming where uptake is low, and (4) analyse agro-economic and environmental consequences of alternative policies affecting the uptake of organic farming. A team with agronomic, ecological and economic expertise, with documented experience in cross-disciplinary collaboration, will pursue these aims using a combination of analyses of existing data on uptake of organic farming, empirical studies across scales from fields to farms, and ecological-economic modelling and analyses. We will do this in interaction with relevant stakeholders to inform the development of policies such as the Common Agricultural Policy and actions to increase organic consumption, to optimize the uptake of organic farming for balancing agriculture’s contribution towards achieving the sustainable development goals.
