Iowa Land Rental Prices Up

An authoritative annual survey of cash rental rates for Iowa farmland, a bellwether for the national market, shows cost per acre have increased, but by no more than the rate of inflation. However, farmland rental prices for the lower quality land are up the fastest, suggesting someone has found a way to make use of low-grade farmland.

This is the fourth successive year of relatively stable rates at levels around 18% lower than the historical peak reached in 2013 at $270 per acre. The survey was carried out in early spring so the effect of the lockdown may yet change results later in the year.
In comparison, corn and soybean prices received by farmers in Iowa declined by 49% and 45%, respectively, since mid-2013. So the underlying value of the land could be said to have increased, while yields per acre are falling in cash terms.

The 2020 Iowa cash rental rate survey was conducted this spring by Iowa State University. Iowans supplied 1,592 responses, reporting typical cash rental rates in their counties for land producing corn, soybeans, hay, oats and pasture. Of these responses, 43% came from farmers, 32% from landowners, 13% from professional farm managers and real estate agents, 6% from agricultural lenders, and 6% from other professions and respondents who chose not to report their status. Respondents indicated being familiar with a total of 1.6 million cash-rented acres across the state.

Different regions experienced different changes in cash rents: from a 4.6% increase in Crop Reporting District (CRD) 3 to a 2.4% drop in CRD 9. Northern and central Iowa (CRD 1 to 6) have, on average, 21% higher cash rents than southern Iowa (CRD 7 to 9). The chart accompanying this article compares the results for 2020.

Results available by county

The survey compares farmland rental prices for each district by the quality of land — high, medium and low. Not all land qualities have seen their average cash rents increase proportionately. Looking at statewide averages, high-quality land experienced a 0.4% increase, from $256 per acre in 2019 to $257 in 2020. Medium-quality land experienced a 1.4% increase, from $220 per acre in 2019 to $223 in 2020. Low-quality land experienced a 2.7% increase, from $183 per acre in 2018 to $188 in 2020.

Average cash rents in Iowa, in $ per acre (nominal)

Detailed results by county and crop are provided on the ISU Ag Decision Maker article Cash Rental Rates for Iowa 2020 Survey, C2-10. There was considerable variability across counties in year-to-year changes, as is typical of survey data, but 59 counties experienced increases in average rents for corn and soybeans. The report also shows typical rents for alfalfa, grass hay, oats, pasture, cornstalk grazing and hunting rights in each district.

Love those Tesla-lovers

Jason Hughes is a happy hacker – but not of computers – he is known for leaking Tesla’s plans ahead of the company’s actual announcements, and now he has revealed photos of his own Tesla battery-powered compound in North Carolina. The 4,500 square-foot home has 102 commercial-grade solar panels to capture energy from the sun which then gets stored into a home battery storage unit composed of battery modules ripped from two Tesla Model S 85 kWh packs.

The 44.4 kW home solar system produces enough energy to not only power the entire home and all of its electrical appliances, but also provides enough energy to charge a pair of his and hers Model S each day. The end result is an elaborate home-engineered system that took roughly a year to design and build, and has allowed Hughes and his family to remain 99% self-sufficient for the past two years.

The battery banks used for storing solar energy are derived from*battery packs found from a salvaged Model S. Hughes dismantled the packs to create a stacked array of battery modules. A total of 36 modules are used in the home set up which equates to 2.25x Model S 85 kWh battery packs.

Here’s a video of Hughes performing a teardown of one of the Model S battery packs.

COSTS OF SOLAR POWER

Hughes says a large portion of the overall expenditure went to the $40k cost in Tesla batteries. He admits that the project likely doesn’t make sense from a financial perspective, but it’s important to understand that the value of his project goes beyond what a cost benefit analysis may yield.

Beyond being able to show that living solely off of sustainable energy is possible, the main inspiration behind his yearlong project was his father who taught him at a young age of 9 how to build a small off-grid solar system that produced enough energy to power his bedroom light, a small TV and a PC. That became the catalyst to what would become a lifelong dream to design an off-grid system capable of powering an entire house, along with electric vehicles.
