Management practices for black lentil green manure for the semi-arid Canadian prairies

S. A. Brandt Canadian Journal of Plant Science 1999. doi:10.4141/p97-091

Other claims from this paper (10)

Intervention effect Green manure strategies did not improve succeeding wheat yield over summerfallow.
Intervention effect Green manure strategies did not improve wheat grain protein concentration over summerfallow.
Observation Standing lentil strips at bud-stage incorporation protected against wind erosion.
Intervention effect Bud-stage glyphosate without incorporation reduced available soil nitrogen.
Intervention effect Bud-stage 2,4-D amine without incorporation reduced available soil nitrogen.
Intervention effect 2,4-D did not stop lentil growth and water use soon enough to prevent a reduction in subsequent wheat yield.

Mechanism The authors attributed the lack of wheat yield gain to summerfallow filling the rooting zone with water.
Recommendation Early incorporation with standing lentil strips was recommended if green manuring is used.
Observation Green manuring lacked a consistent advantage over summerfallow even with improved water management.
