Understanding Kernza®
Kernza is a perennial grain crop developed from intermediate wheatgrass. It offers a sustainable alternative to traditional grains like annual wheat. Its deep roots and regenerative attributes make Kernza vital for environmental health.
Selective Breeding: Origins and Development of This Species of Intermediate Wheatgrass (thinopyrum intermedium)
Kernza originated from intermediate wheatgrass. It was developed by The Land Institute, located in Salina, KS, as part of an effort to make agriculture more sustainable. Kernza® is only part of many perennial agriculture projects the institute is working on. With Kernza®, the institute aimed to create a grain that could be harvested multiple times as a perennial, unlike conventional wheat.
Initially, intermediate wheatgrass had small seed heads. The Land Institute bred Kernza to improve seed size and yield. This was crucial for its viability as a commercial crop. Becoming a viable commercial crop helps incentivize more regenerative agricultural practices and addresses ecological challenges.
Characteristics of Kernza® Perennial Grain and Comparison with Annual Grain Crops
Kernza grain possesses distinct qualities that differentiate it from other grains. As a perennial crop, it regenerates, or grows back, each year without the necessity for replanting. Unlike annual crops such as wheat, which require replanting each year, Kernza reemerges from its existing roots. This characteristic minimizes the need for tilling and reduces soil disturbance.
Additionally, its extensive root system aids in preventing soil erosion and conserving water, thereby enhancing soil health Because of its roots, Kernza reduces nitrate leaching into water systems, unlike many conventional crops, in contrast to many traditional crops.
Like many other annual grains, this grain can be incorporated into a variety of food products, including flour and cereals. While its flavor is akin to that whole wheat flour, it provides greater environmental advantages. And it’s these traits make Kernza a promising candidate in the movement towards sustainable agricultural practices.
Also, it should be noted, that post-harvest, the remaining stalks can be used for forage for cattle. This eliminates the need to bring in another feed source into a farming operation.
All these distinctions underscore Kernza’s potential to enhance agricultural sustainability and improve water quality. By integrating this perennial grain, we can strive for more environmentally friendly agriculture. Learn more about Kernza’s role in perennial agriculture from The Land Institute.
Sustainable Perennial Agricultural Practices: How Kernza® Helps With Sustainability
Soil Health and Structure
We’ve already talked about Kernza®’s root structure. This helps improve soil health; healthy soil is key for sustainable agriculture. Healthy soil supports plant growth and reduces soil erosion. By using perennial grains like Kernza, farmers can maintain soil integrity. Kernza has deep roots, which helps stabilize the soil. It prevents erosion and can improve the soil’s structure. This practice increases organic matter, promoting a thriving soil food web. A diversity of soil organisms is essential for nutrient cycling.
Besides preventing degradation, Kernza’s roots enhance soil conservation. These roots reach deep into the ground. With this, the plant draws nutrients from deeper soil layers, which are often untapped by annual crops. The result is less reliance on chemical fertilizers, which is environmentally beneficial.
Water Usage and Quality
Water conservation and improved water quality are key goals of sustainable farming. Kernza®’s deep roots tap into groundwater, lessening the need for frequent irrigation. This is particularly beneficial in areas facing water scarcity. Likewise, with less irrigation, water pollutants like nitrate are reduced, contributing to cleaner waterways. Improved water quality protects aquatic life and reduces health risks for humans.
Carbon Sequestration and Climate Change
Combatting climate change through carbon sequestration is part of the approach to sustainable agriculture. Kernza’s deep roots capture carbon from the atmosphere, storing it in the soil. This process helps reduce greenhouse gas emissions, a major driver of climate change. Additionally, Kernza requires fewer inputs like fertilizers and pesticides, which reduces emissions related to agricultural practices.
By increasing carbon storage underground, perennial grains contribute to global cooling efforts. Using such plants helps mitigate climate effects, making them crucial in the quest for sustainable solutions. As droughts continue to affect the Midwest, killing trees which are huge sequesters of atmospheric carbon, perennial crops like Kernza® can play the role that trees did in carbon sequestration.
