A review of soil fertility management and crop response to fertilizer application in Ethiopia:Towards development of site- and context-specific fertilizer recommendation uri icon

abstract

  • More than 80% of the Ethiopian population isdependent on agriculture, which contributes about50% of the country?s gross domestic product (GDP)and more than 80% of its export earnings. Althoughthe agricultural sector is the engine of economicgrowth and the country has designed an ?AgriculturalledIndustrialization?, the agricultural sector is stillcharacterized by severe soil erosion, high levelsof nutrient mining, low use of external inputs, lowproductivity and limited capacity to respond toenvironmental shocks. Thus, the country is grapplingwith a daunting challenge: produce more food for afast-growing population on low fertility soils on landowned by poor smallholder farmers who are unlikelyto afford adequate input use. To address thesechallenges, several efforts are being made since the1960s to assess the potential effects of various sourcesof organic and mineral fertilizers on crop yield and soilfertility status of the differing farming systems in thecountry
