Green manure as a nitrogen source for wheat in the southeastern United States

Julia B. Nelson; Larry D. King American Journal of Alternative Agriculture 1996. doi:10.1017/s0889189300007050

Other claims from this paper (7)

Intervention effect Wheat yield with green manure only was lower than yield with 90 kg N/ha (about 65%).
Intervention effect Wheat yield with green manure plus 45 or 90 kg N/ha did not differ from yield with 90 kg N only.
Observation Soil inorganic N to a depth of 30 cm declined from as high as 40 kg/ha in fall to less than 10 kg/ha in spring during the first year.
Intervention effect Fertilizer N gave a greater potential for N leaching than green manure.
Observation An average of 80% of white clover N was recovered as soil inorganic N in a laboratory incubation at 10 °C.
Observation Field recovery of clover N (soil inorganic N plus N in wheat biomass) was only 21%.
Intervention effect Spring fertilizer N applied to green manures could decrease N leaching loss (author interpretation).

Other claims from this paper (7)

Intervention effect Cover crops did not increase the AONR compared with the no-cover crop treatment.
Observation In 2021, with near-normal precipitation, corn yield at the AONR and the AONR were the highest of the three years.
Observation In 2022, with about half the 30-year average rainfall, yield at the AONR decreased across treatments.
Intervention effect In 2023, cover crop treatments had no significant effect on the AONR.
Observation In 2023 there was a decrease in yield compared with near-normal precipitation in 2021.
Mechanism Weather was the dominant factor driving the AONR.
Recommendation The results do not support the need for higher N rates after winter cover crops.
