Using the Share Rent Equivalent Model to Determine Farmland Value

Every year, the Farm Service Agency (FSA) national office reviews the Soil Rental Rates used for the Conservation Reserve Program (CRP). The FSA has recently announced that county-average rental rates will be updated based on the 2023 National Agricultural Statistics Service (NASS) Cash Rent Survey results for dryland rent estimates. When considering the prevalent farm lease arrangements and production practices, NASS survey results may not provide accurate estimates. This results in a county-average rental rate that does not reflect typical rent paid in a county. For example, Figure 1 highlights the percentage change in proposed CRP rental rates in Arkansas between 2023 and 2024, where negative values represent counties facing lower CRP rental rates than in 2023.

Several acceptable models can be used to address rental discrepancies or determine an alternative rate. One such method approved by the FSA is the “Share Rent Equivalent Model.” The model intends to infer cash rents in situations (e.g., counties) where share leases predominate available data or where share leasing is the rule rather than the exception. Acceptable supporting data sources for the model include an average of the most recent three years of yield data, including NASS county yields. When NASS yields are unavailable, RMA T-yields can be substituted. 

Arkansas counties are an example, though this model applies to any county in the southeast region of the United States. Given the prevalence of 20% and 25% share leases found in the southeast region and the limited amount of non-irrigated crop production, the model incorporates county-specific production practices and lease structures that more accurately reflect the soil value and environmental benefits of the CRP program. Table 1 utilizes the “Share Rent Equivalent Model” to determine an alternative cash rent for 20% and 25% share leases under a wheat/soybean double cropping system for Arkansas County, Arkansas.  

Table 1. Share Rent Equivalent Model for Wheat/Soybean Production, Arkansas County

CropWinter WheatNon-Irrigated SoybeansWinter WheatNon-Irrigated Soybeans
Share Rent (%)25%25%20%20%
RMA T-Yield (bu/ac) (2020-2022 avg.)63416341
RMA 2023 Harvest Price$6.60$12.84$6.60$12.84
Cash Rent Equivalent ($/acre)$103.95$131.61$83.16$105.29
Total Cash Rent Equivalent ($/acre)$235.56$188.45
Note: Share Rent (%) * RMA T-Yield * RMA 2023 Harvest Price = Cash Rent Equivalent. 
Total Cash Rent Equivalent = Cash Rent Equivalent (Winter Wheat) + Cash Rent Equivalent (Soybeans).

The results in Table 1 more closely resemble non-irrigated cash rents in the representative county, particularly in the current commodity market environment for grains. Figure 2 is a map of alternative CRP rental rates derived from the “Share Rent Equivalent Model” for 20% crop-share arrangements in predominate agricultural counties in Arkansas. Furthermore, the model’s accuracy is determined by calculating the percentage change between the 2023 effective CRP rental rate and the alternative 2024 CRP rates from the model. Figure 3 maps this percentage change for each county in Arkansas. According to Figure 3, our estimates are only marginally higher than what was stated in 2023. Therefore, we can conclude that the “Share Rent Equivalent Model” reflects existing CRP rental rates more accurately than the survey-based approach. Work with your local FSA office to determine if the Share Rent Equivalent model more accurately reflects cash rent in your county.
