Technology, Innovative Farming Practices Advance Wheat Farm SustainabilityThu, 18 Feb 2021 14:41:57 CST
Shelbi Knisley, USW Director of Trade Policy writes In the latest issue of USwheat.org, on technology in farming.
Across the United States, farmers are producing more and better quality wheat using fewer natural resources, including land. According to an American Farm Bureau Federation report, in 2018, about 8 million fewer acres (3.24 million hectares) were needed to produce the same amount of wheat as in 1990.
With the Biden Administration establishing clear policy goals to fight climate change and reward conservation, it is more important than ever to share the success stories of how U.S. wheat farmers have employed sustainable practices for many years to protect their land and make a positive impact on the environment.
U.S. farmers are more economical and sustainable today by implementing agronomic practices and investing in technologies, research, and development. Technology plays an important role in making U.S. agriculture sustainable. When breeding techniques and advanced technologies are used to produce high-yielding, high-quality wheat varieties, it contributes to preserving the land’s natural resources through water and soil nutrient conservation that work in harmony with local conditions.
In their production, U.S. wheat farmers apply many aspects of the following sustainable tools and practices:
Reduced Tillage. The USDA Economic Research Service reports that reduced tillage has grown in popularity and is now practiced on nearly 70% of U.S. wheat acres. While at times a necessary tool, traditional plowing and other deep tillage can be concerning. Continuous wheat production with deep tillage contributed to the infamous U.S. “Dust Bowl” of the 1930s. The introduction of reduced-till and no-till practices have helped reduce soil erosion and increase water retention on dryland crops. This practice also reduces fuel use and promotes carbon sequestration. Read more about the sustainability of practicing no-till farming here.
Crop Rotation and Cover Crops. After a harvest, most wheat farmers switch to a different crop in the same fields, a practice known as crop rotation. More and more farms are planting “cover crops” after harvest that will be incorporated into the soil before the next crop is planted. Both these practices are beneficial in preserving soil health as well as conserving water. Cover crops add soil nutrients and organic matter and help prevent soil and water runoff. In one study, for example, Desert Durum® wheat farmers who rotate to lettuce crops following their durum harvest, have reduced water use on average about 30%.
Water Conservation. Wheat is a naturally water-efficient crop. In much of the United States, wheat is grown during cooler months and has a longer growing season – providing more opportunity for it to capture naturally occurring precipitation. Only about 10% of U.S. wheat acres are irrigated. Even when wheat is irrigated, it often needs less irrigation than many other crops.
Precision Agriculture. Farmers are using technologies such as crop yield monitors, soil maps and global positioning systems (GPS) as well as drones to apply inputs more precisely, monitor plant health, and collect data on soil nutrients and other natural resources. For example, such technology allows farmers to adjust seed, fertilizer and crop protection inputs with near pinpoint accuracy, ensuring the right rates are applied or seeded in the right location while on the go in their fields. Greater efficiency through precision agriculture practices means greater economic and environmental sustainability.
Oregon soft white wheat grower Bob Johns (right in the photo at the top of the page) and his farming partner Chris Williams (left) say technology from improved breeding to drones help them make better-informed decisions about how inputs and management affect their yields, soil and crop health and profitability.
U.S. Wheat Associates (USW) supports finding new ways to improve wheat quality and increase production with less impact on the environment.
