Effects of Gypsum Application Rate and Frequency on Corn Response to Nitrogen

Vijayasatya N. Chaganti; Steve W. Culman; Warren A. Dick; et al. Agronomy Journal 2019. doi:10.2134/agronj2018.10.0683

Other claims from this paper (8)

Intervention effect A positive corn yield response to gypsum application occurred only in 2017 at the Northwest site.
Intervention effect Gypsum applied at 4.4 Mg ha −1 significantly decreased corn yields at the Northwest site in 2017 and the Wooster site in 2016.
Recommendation The best management strategy may be to apply lower gypsum rates either annually or biannually.
Intervention effect Gypsum did not improve corn response to N at either study site.
Intervention effect Gypsum applications significantly increased tissue, grain and extractable soil S concentrations.
Association S concentrations decreased as gypsum application frequency decreased.
Intervention effect Frequent gypsum applications at lower rates were better than a one-time large application.
Recommendation Where S deficiency may occur, gypsum at a low frequency would increase S availability.

A Model–Data Fusion Approach for Predicting Cover Crop Nitrogen Supply to Corn

Charles M. White; Denise M. Finney; Armen R. Kemanian; et al. Agronomy Journal 2016. doi:10.2134/agronj2016.05.0288

Other claims from this paper (8)

Observation Model parameters suggested all winterkilled cover crops caused net nitrogen mineralization.
Method / resource The model assigned a C humification coefficient of 0.40 to winter hardy cover crop residues.
Association Yield response per potentially mineralized nitrogen was greater for winter hardy than winterkilled cover crops.
Method / resource With tillage, winter hardy cover crops had a modeled response coefficient of 0.034.
Method / resource Without tillage, winter hardy cover crops had a modeled response coefficient of 0.020.
Method / resource Winterkilled cover crops had a modeled response coefficient of 0.0084.
Association Preemptive competition for soil nitrate reduced corn yield response.
Recommendation The authors propose the model data fusion approach for guiding adaptive cover crop and nitrogen fertilizer management.

Hybrid Selection and Agronomic Management to Lessen the Continuous Corn Yield Penalty

Alison M. Vogel; Frederick E. Below Agronomy 2018. doi:10.3390/agronomy8100228

Other claims from this paper (6)

Observation Continuous corn had a 1.53 Mg ha−1 yield penalty in 2014.
Observation Continuous corn had a 2.72 Mg ha−1 yield penalty in 2015.
Intervention effect Intensive management raised grain yield across rotations by 2.17 Mg ha−1 in 2014.
Intervention effect Intensive management raised grain yield across rotations by 2.28 Mg ha−1 in 2015.
Intervention effect For selected hybrids, intensive management reduced the continuous corn yield penalty by 30 to 80%.
Recommendation The authors conclude that management and hybrid selection can improve continuous corn productivity.
