How forage sorghum helps preserve the Ogallala Watershed
The High Plains region of the United States has historically been an important agricultural centre. It contributes significantly to economic growth and the agricultural sector. A variety of crops, including forage sorghum, are actively grown here. However, in recent years, farmers have faced a serious problem with water shortages.
Parts of Texas, Nebraska and Kansas belong to the High Plains. This region has long been associated with livestock production. To fatten the cattle, local farmers grow a variety of crops. But sorghum is the most important.
One of the largest aquifers in the world, the Ogallala Aquifer, is located in the region. It has long served as the main water artery for agriculture and livestock. In recent years, however, the situation has deteriorated. In some areas, the canal’s irrigation capacity has declined by more than 90%. This trend threatens the further development of the region as an agricultural centre.
The main reason for the depletion of the reservoir is the intensive activity of farmers due to market difficulties. A combination of factors is forcing farmers to increase water use, accelerating the depletion of the Ogallala.
Benefits of growing the crop
One way out is to grow forage sorghum. This crop will help solve the problems of fattening livestock in water-limited environments. Sorghum production requires less water than maize. And the feed values of the two crops are almost identical.
Advantages of sorghum:
1. Sorghum requires half as much water to grow. Corn silage, on the other hand, absorbs 20 inches of additional moisture per acre. Growing sorghum reduces the amount of water drawn from the Ogallala Aquifer.
2. Forage sorghum is ideal for areas with limited irrigation.
3. Its deep root system and high drought tolerance allow it to be grown on low-fertility soils.
In addition to water management, sorghum is effectively used as a livestock feed. Grain, silage and barda after ethanol production provide a complete feed for a variety of livestock. And the crop can be used to feed both small livestock and dairy cattle. This flexibility makes sorghum an attractive option for farmers looking to optimise costs and maintain stable production.
Despite the crop’s advantages, US farmers have been slow to embrace sorghum. The process, like any change, takes time and adaptation. But the rapid depletion of the Ogallala is forcing the search for new ways to reduce negative environmental impacts. Incorporating sustainability principles into farming operations will enhance the economic component. The goal is to maintain farm profitability, which continues to be threatened by global and domestic factors.
