This paper from India and the NW IndoGangetic Plains assesses the system productivity and soil quality in a CA-based maize-wheat rotation as an alternative to rice-wheat. They compared no-till (NT) with conventional (CT); residue mulch (M+) versus no residue (M0); three N levels, 50 (N1), 100 (N2), and 150 (N3). The soil was sampled from 3 depths down to 30cm. Various soil properties were measured. Available P and K was higher in the M+ plots as expected. NTM+ increased soil microbial biomass C. The highest soil quality index was the NTM+ N3 treatment and the lowest CTM0, N1. Adding maize in rotation with rice improves soil quality.

Cornell Conservation Agriculture Group (soilhealth.org)'s insight:
This paper from NE Himalayas, where low yielding maize-fallow is the main cropping system on the sloping hilly areas is a daunting task for increasing farm productivity, nutritional security and economic viability. The paper explains the results of a field experiment over 3 years under organic management that looks at CA vs CT and 6 diversification options. Results show CA had higher productivity than CT. Crop diversification also had higher system productivity, net returns, net energy returns than the local cropping system. They conclude that conservation agriculture improved soil health and performed better than conventional agriculture in maize-based intensive cropping systems. Crop diversification with maize-sweet corn- pea or broad bean can potentially increase calorie and protein consumption and farm profitability.

Cornell Conservation Agriculture Group (soilhealth.org)'s insight:
The paper evaluates various methods of tillage, residue management and nitrogen application on wheat yield, water use efficiency (WUE) and nitrogen use efficiency NUE). Tillage consisted of CT and NT, with (R+) and without (R0) maize residue, and 3 N levels, 60,120 and 180 kgN/ha.Tillage and residue management influenced the grain and biomass yield of wheat. Over the two years, NT exhibited a 7% higher WUE compared to CT, but the change was insignificant. However, in years with lower rainfall, crop residue mulching had a significant positive impact on WUE, while in years with higher rainfall its effect on WUE was insignificant.

Cornell Conservation Agriculture Group (soilhealth.org)'s insight:
This research used the CERES wheat model to simulate wheat growth , yield, and nitrogen dynamics in a 8-year maize-wheat CA system. They calibrated the model using field data, including plant phenological phases, leaf area index, above ground biomass, and grain yield from the 2019-20 to 2020-21 growing seasons. They conclude that the model has potential to assess the impacts of tillage and nitrogen management that will help with planning and more efficient resource management. They also have a discussion of the future implications for the successful implementation of this DSSAT-CERES wheat model.

This South Dakota study assessed the impact of tillage CT and NT); crop rotation: 2-year corn-soybean, 3-year corn-soybean-oat and 4-year corn-soybean-oat-wheat; cover crops (cover crop [CC] and no cover crop [NC]); and drainage (tile drainage [TD] and without drainage [ND]) on soil organic matter (SOM), bulk density, wet aggregate stability (WAS), and field-saturated hydraulic conductivity (Kfs). Soil samples were collected over 2 years from five depths and analyzed for SOM, bulk density, and WAS. NT increased soil bulk density, soil organic matter, and wet aggregate stability (WAS) for the 0- to 10-cm depth but decreased Kfs within the soil profile compared to CT. CC and tile drainage(TD) had minimal impact on SOM, bulk density, WAS, and Kfs.
