As harvest approaches, propane is a key ingredient for anyone using a high-temperature system to dry corn. A case study conducted by Mark Hanna, agricultural and biosystems engineering specialist for Iowa State University Extension and Outreach, can help farmers as they plan for harvest and winter storage.
The costs associated with installing solar arrays have dropped over the last several years, making them much more cost effective to install on a farm or acreage. As they become more affordable, these solar arrays are becoming a viable source of energy for farmers, especially farmers who have large barns to ventilate in the summer or fans on grain bins.
