Abstract

Organic amendments have been used to restore productivity to disturbed soils such as those on abandoned oil and natural gas wellsites. A study was conducted on three abandoned wellsites in southern Alberta, Canada to examine the effects of one‐time applications of alfalfa ( Medicago sativa L.) hay or beef cattle ( Bos taurus ) feedlot manure compost on soil properties under continuous wheat ( Triticum aestivum L.). The base amendment rate (1×) [dry wt.] was 5.3 Mg ha −1 for compost and 3.1 Mg ha −1 for alfalfa. The five amendment rates of 0, 1×, 2×, 4×, and 8× were soil‐incorporated at the wellsites. Although approximately twice as much C was applied with alfalfa than with compost, final SOC content was similar for the two amendment treatments, indicating the greater stability of compost‐derived C. Nitrate N content in the 0‐ to 60‐cm depth was not affected by compost rate (mean 213 kg ha −1 ) but increased by 7.78 kg ha −1 for each Mg ha −1 increase in alfalfa rate. This result reflects the greater stability of compost‐N compared with alfalfa‐N and suggests a lower risk of NO 3 –N leaching with compost application. Compost rates >20 Mg ha −1 resulted in excessive extractable P build‐up in the topsoil (up to 95.7 mg kg −1 ), which may pose environmental risk to surface water. We recommend amending wellsites with up to 12 Mg ha −1 of alfalfa or <20 Mg ha −1 of compost during reclamation to improve C storage and nutrient cycling while minimizing nutrient loss to water systems.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
