Abstract/Summary:
The project aims to expand knowledge of greenhouse gases (GHGs) in organic production by measuring N2O emissions and soil carbon storage for wheat, oat and flax grown in a variety of organic production scenarios.
Objectives are to: 1) Compare organic and conventional production in terms of N2O emissions over a growing season. 2) Compare organic and conventional production in terms of soil C storage over the long-term (32 years). 3) Determine the GHG footprints of organic wheat, oats and flax compared with conventional production. 4) Evaluate how mixing legume green manure cover crops with non-legume plant species affects N2O emission during and after the green manure phase. 5) Evaluate how reducing tillage in the legume green manure cover crop termination phase affects N2O and ammonia emissions after legume termination. 6) Determine if fall cereals reduce the post-termination N2O emissions from alfalfa hay crops.

- Abstract/Summary: Trials were established at Yorkton, Indian Head, Swift Current, Scott, Melfort, Prince Albert, and Redvers to determine if delaying the crop’s access to nitrogen could decrease lodging, increase protein, and maintain test weight and yield of milling oat. Applying a portion of the total N as dribble banded UAN (4 leaf vs boot stages) or side banded ESN was compared to side banding all the N as urea. These comparisons were made at total N levels of 110 and 140 lb/ac (soil + fertilizer). Some benefits from managing N were detected, however, they were rare and inconsistent. While yield and protein did not typically differ between levels of N management at most sites, applying a portion of the total N as UAN at the boot stage decreased both yield and grain protein at Indian Head. This highlights the environmental risks associated with split applications. However, there were a couple instances where supplying a portion of the N as ESN or dribble banded UAN did increase grain protein by providing late season N to the crop. Levels of lodging were very low at most locations, making it difficult to detect any differences between N management. However, even at sites where lodging was high, no significant effects were detected. Maintaining oat test weight with UAN at the boot with the use of ESN was detected in a couple of instances at Swift Current. However, these effects were not detected at any of the other locations despite test weight being responsive to added N at 4 of the locations. In conclusion, there was limited evidence that applying a portion of the N requirement as ESN or dribble banded UAN could maintain yield and test weight, increase grain protein, or reduce lodging. Effects were inconsistent between sites and even between levels of total N within a site.

- Principal Investigators: Bill May, Indian Head Agricultural Research Foundation (IHARF)
- Project Dates: May 2016 - Febuary 2017
- Abstract/Summary: This project aimed to: 1) validate, under local conditions, research showing that oat requires moderate amounts of N and that test weight declines as N rate is increased; 2) expose growers to new oat cultivars that may be better than cultivars currently grown in the trial area; and, 3) determine if the test weight of current oat cultivars vary in the stability of their test weight as the N rate is increased. Four oat cultivars were chosen specific to each location (two popular and two new cultivars with potential). N rates used (kg N/ha): 40, 60, 80, and 120.

- Principal Investigators: Mike Hall
- Project Dates: April 1, 2023 – Feb 28, 2024
- Abstract/Summary: This project aims to determine the yield and test weight response of oats to 15% and 30% reductions in optimum rates of N. The specific rates of soil plus fertilizer N tested will be 125 lb/ac, 106 lb/ac, 88 lb/ac and no applied N. Two varieties of oats will be used in this project – CS Camden and CDC Arborg.
