爱荷华农民测试Kernza(一种可持续的常年粮食)在当地条件下的耐力和生存能力。 Iowa farmer tests Kernza, a sustainable perennial grain, for resilience and viability in local conditions.

位于爱荷华中部的农民Lee Tesdell(Lee Tesdell)在七英亩的地块上种植来自中间麦草的常年谷物Kernza(Kernza), Farmer Lee Tesdell in central Iowa is growing Kernza, a perennial grain from intermediate wheatgrass, on a seven-acre plot to test its viability in the state’s climate. 深根有助于减少土壤侵蚀和吸收硝酸盐,在目前对饮用水硝酸盐含量高的担忧下,有可能改善水质。 The deep roots help reduce soil erosion and absorb nitrates, potentially improving water quality amid ongoing concerns over high nitrate levels in drinking water. 特斯德尔将作物用于谷物、干草和牧羊,加工成片片或通过内布拉斯加伙伴酿造成的原料。 Tesdell uses the crop for grain, hay, and sheep grazing, processing it into flakes or brewing ingredients via a Nebraska partner. 虽然凯尔扎要求的投入和拖拉机通过量比年作物少,但其低产量和市场需求有限阻碍了广泛采用。 While Kernza requires fewer inputs and tractor passes than annual crops, its low yields and limited market demand hinder widespread adoption. 虽然在干旱地区和明尼苏达州大有希望,但仍在继续研究其在爱荷华州的表现,那里仍然是试验阶段。 Though promising in drier regions and Minnesota, research continues on its performance in Iowa, where it remains experimental.
