Dо nоt аnswer this questiоn - this is used to provide the two study cаses below. If you hаven't done so already, you can open/download the scorecard here. Note that you will not be asked to evaluate impacts on global diversity ("Negative impact on global diversity (Yes/No)") even though it's part of the scorecard. Word limits: 175 words should be enough to answer each question. If answers are longer than 200 words, we will not consider words added beyond 200 words. Case Study 1: An industrial grain farm in France This system is located in the Beauce region which is considered the French bread basket. It is one of the most productive regions in Europe due to its deep, well-structured and fertile clay-loam soils and because it rests on one of the largest aquifers in Europe. This aquifer allows for widespread pumping. The landscape is characterized by flat, wide open fields. The climate is relatively dry with 500-600 mm of rainfall per year, with a few strong storms every summer. The principal crop grown in this region is wheat, but there are also a variety of other cereal and oilseed crops that are produced. Typical farms are large. Farms rotate crops on a 3-year rotation that is typical for the region: Winter Wheat – Barley – Canola (or sunflower). Winter wheat is seeded late summer and harvested the following year, in late spring or early summer, whereas other crops are seeded in spring and harvested in fall. Individual farms typically have several fields, allowing them to grow each crop of the rotation every year. After harvest, the remaining stalks and dry matter are left in the field and strips are tilled in before sowing the next crop (roughly half of the field ends up being tilled). Synthetic nitrogen fertilizers are applied twice during the wheat season, at planting in late summer and in the subsequent spring upon flowering. For other crops, N inputs are also split between a dose at planting and the rest as a side-dress. Other nutrients (e.g., P & K for all, S for canola) are added based on soil testing, under synthetic form. There is no addition of organic amendments (e.g., composts or manures). No cover crops are used per se, but a clover crop is inter-seeded during the spring phase of wheat before barley, and during the late season of canola or sunflower. This gets terminated at the same time as the cash crop, and tilled in. Herbicides are applied in a preventive manner. The farmer scouts their fields for pests and applies pesticides when a disease/pest is found in the field. Most of these growers rely on supplemental irrigation from the groundwater, typically through overhead systems (pivot, linear or sprinkler systems) that are turned on as needed, based on the judgement and experience of farmers. Fields are usually cultivated to the edges in order to maximize the land use for production. Farmers will share large equipment needed for crop management, such as combines (harvesting machines), fertilizer spreaders, etc. Most of the production is sold within France once grains are processed within the region. Case Study 2: An organic grain rotation in Pennsylvania This system consists of a 3-year organic rotation: corn-soybean-winter wheat. Cover crops consist of vetch before corn and rye before soybean; winter wheat is sown right after soybean hence there is no cover crop between soybean and wheat. Vetch is planted after wheat, and it grows until corn is sown again. The area (i.e., not necessarily this specific farm) consists of a mosaic of grain cropping farms, pasture-based dairies, and some land used for forestry. Although there is some land enrolled in the Conservation Reserve Program (i.e., a program that pays farmers not to farm a fraction of their land for conservation purposes) as pollinator habitat, windbreak or riparian protection, many fields are planted “ditch to ditch”. The typical soils are alfisols, which contain a fair amount of clays, resulting in good fertility and water retention, although drainage can be poor. Average annual rainfall is high, around 1200 mm, thus these systems are entirely rainfed. Each crop is grown as a monoculture during rotation, although different fields on the farm are under different crops, allowing to grow each crop of the rotation every year. The farm features diverse tree plantings to act as a windbreak among fields, and has enrolled acreage into the CRP program as pollinator habitat. Except for N-fixation originating from legumes included in the rotation, this system does not add any fertilizers per se. However, before the corn and wheat crops, they add a large input of composted dairy manure that they get from a neighboring farm to "feed the soil" and provide organic matter. Because it is composted, their rationale is that they can add these organic inputs (and the nutrients they contain) at a high rate (i.e., beyond crop requirements) and the release of nutrients should be gradual and constant over the course of the following three years. Given the limited weed control options and multiple cropping phases (cash crops and cover crops), this system uses tillage more frequently, with a moldboard plough (i.e., soil inversion) on the whole field multiple times per year. Frequent cultivation and hoeing is used to control weeds during the season. This system is entirely based on rotation to provide pest control (i.e., no pesticides of any kind are used), although the CRP land also provides habitat for natural enemies of pests. Given the constraints of organic production, cereal yields are lower compared to nearby conventional farms, although soybean yields are similar. During drought years (every 5-6 years), cereal yields are comparable to conventional systems. Finally, as most growers in the area are conventional, they need to ship their production outside of the region to be processed according to organic certification. However, all production is consumed within the US.
