Growing Use and Impacts of Chemical Fertilizers and Assessing Alternative Organic Fertilizer Sources in Ethiopia

This paper reviews relevant facts and statistics about the benefits impacts of growing use chemical fertilizer with a focus on soil fertility, crop productivity, alternative sources biofertilizers. Agriculture in Ethiopia is main source economy, it key contributor export value provider raw materials to processing industries. However, Ethiopian agronomical production characterized by low output, lack infrastructure, level technology enormously dependent rainfall availability. In Ethiopia, fertility reduction evolving as serious contest causing yields, research findings reported that, at country level, nutrient balance indicated depletion rate 122 kg N ha−1 yr−1, 13 P 82 K yr−1. To control depletion, primarily fertilizers are used essential plant nutrients. increase was relative other developing countries; however, now, steadily increasing.
