Improving fertilizer response of crop yield through liming and targeting to landscape positions in tropical agricultural soils.

Nutrient management research was conducted across locations to investigate the influence of landscape position (hill, mid-, and foot slope) in teff () and wheat () yield response to fertilizer application and liming in the 2018 and 2019 cropping seasons. The treatments included 1) NPS fertilizer as a control treatment (42 N + 10P + 4.2S kg ha for teff and 65 N + 20P + 8.
