A combination of stratified and systematic sampling techniques was employed to draw representative soil samples.

Soil type and fertilizer rate affect wheat ( L.) yield, quality and nutrient use efficiency in Ayiba, northern Ethiopia.

The blanket NP fertilizer recommendation over the past five decades in Ethiopia did not result in a significant increment of crop productivity. The main lack of success was highly linked to the extrapolating approach of one site success to others without considering the climate, soil, and ecological setting and variations. As a result, a new fertilization approach was desperately needed, and with this premise, new blended fertilizers are now being introduced to replace the conventional approach.
