Perennial forage crops for improved soil nitrogen cycling in East African smallholder dairy systems
Livestock and dairy production are economically important in Rwanda, yet present challenges for
• The farmer-preferred forage Napier grass (Cenchrus purpureus) is an inefficient feed source.
• Shifting to low-nitrifying cropping systems can reduce nitrous oxide (N2O) emissions and prevent the loss of leachable mineral nitrogen (N) from low-fertility soils.
• Little is known about N dynamics resulting from the use of ‘climate smart’ perennial forages, even while they are promoted as a conservation agriculture practice
