“…We conducted the evaluation in two stages. First, the net returns to cereal rye in the crop system were calculated using experimental agronomic data from Marcos et al (2023) and local average prices in a partial budget framework. Partial budgets captured the differences between total profits from no-till corn production in fields planted to cereal rye in the fall, and total profits from no-till corn production in fields left fallow over the winter.…”

Unproven economic returns at the farm level are a major barrier to large-scale adoption of cover crops. The objective of this study was to evaluate the short-run private net returns to producers implementing a cereal rye (Secale cereale L.) cover crop preceding the no-till corn (Zea mays L.) phase of a US Midwest corn–soybean (Glycine max [L.] Merr.) rotation in an integrated crop and cow–calf operation. We used experimental agronomic data from six location-years in Iowa to estimate private net returns to cereal rye across alternative scenarios in a partial budget framework. Net returns in the absence of grazing averaged −$123.74 ha−1 and were negative for 82.2% of the treatments, while net returns under partial grazing averaged −$15.24 ha−1 and were negative for 54.8% of the treatments. Early-broadcast cereal rye produced higher biomass and larger net cost savings in the livestock enterprise than late-drilled cereal rye, but it also resulted in higher corn yield penalties. In the no-grazing scenario, net losses for early-broadcast cereal rye were $165.97 ha−1 larger, on average, than for late-drilled cereal rye. Our findings should raise awareness about the low probability of obtaining positive annual private net returns to cereal rye in Iowa in the absence of sizable targeted financial incentives, and inform the policy discussion on the cost-effectiveness of government-sponsored conservation programs.

The integration of grazing cover crops in combination with soybean [Glycine max (L.) Merr.] production has the potential to increase total farm revenue. The objectives of this research were to determine the effect grazing had on subsequent soybean production and the economic implications of this practice. A field trial was conducted at the Coastal Plain Branch Experiment Station (CPBES) in Newton, MS, and the Prairie Research Unit (PRU) in Prairie, MS, from 2021 to 2023 to compare three cropping systems on two distinct soil types. Cropping systems included: conventional soybean (CS); no‐till soybean + cereal rye (Secale cereale L.) cover crop (CC); and no‐till soybean + grazed cereal rye cover crop (GC). Treatments were applied in a randomized complete block design with three replications at each location. Analysis was separated by location. Cover crop, soybean production, animal performance, and economic analysis were evaluated for each treatment. Soybean grain yield varied by treatment; GC (54.6 bu acre−1) was greater than CS (52.3 bu acre−1) at CPBES. At PRU, CS (68.5 bu acre−1) had greater soybean yield than all other treatments. Cover crop forage mass (FM) was 5077 lb acre−1 at CPBES, compared to 3094 lb acre−1 at PRU, resulting in subsequent cattle revenue of $593.64 and $160.29 acre−1 for CPBES and PRU, respectively. Soybean revenue was greatest for GC at CPBES ($691.78 acre−1) and CS at PRU ($867.89 acre−1). Net returns above production costs were greatest for GC at CPBES ($811.59 acre−1) and CS at PRU ($528.58 acre−1). Findings suggest grazing cereal rye cover crop has the potential to increase net returns in a no‐till soybean system on coarse textured soils, but reduces soybean grain yield on heavy, poorly drained sites.
