Lack of accurate information about soil nutrient requirements coupled with limited access to appropriate fertilizers could lead to mismatch between soil nutrient requirements and fertilizer applications. Such anomalies and mismatches are likely to have important implications for agricultural productivity. In this paper we use experimental (spectral soil analysis) data from Ethiopia to examine farmers’ response to soil nutrient deficiencies and its implications for yield responses. We find that farmers’ response to macronutrient (nitrogen and phosphorus) deficiencies is not always consistent with agronomic recommendations. For instance, we find that farmers in our sample are applying nitrogen fertilizers to soils lacking phosphorus, potentially due to lack of information on soil nutrient deficiencies or lack of access to appropriate fertilizers in rural markets. On the other hand, farmers respond to perceivably poor-quality soils and acidic soils by applying higher amount of nitrogen and phosphorus fertilizers per unit of land. We further show that such mismatches between fertilizer applications and soil macronutrient requirements are potentially yield-reducing. Those farmers matching their soil nutrient requirements and fertilizer application are likely to enjoy additional yield gains and the vice versa. Marginal yield responses associated with nitrogen (phosphorus) application increases with soil nitrogen (phosphorus) deficiency. Similarly, we find that farmers’ response to acidic soils is not yield-enhancing. These findings suggest that such mismatches may explain heterogeneities in marginal returns to chemical fertilizers and the observed low adoption rates of chemical fertilizers in sub-Saharan Africa. As such, these findings have important implications for improving input management practices and fertilizer diffusion strategies.

Agricultural intensification in Ethiopia: Patterns, trends, and welfare impacts available in PDF, EPUB and Kindle. Ethiopia has made substantial efforts in the last three decades to increase agricultural productivity through modern input intensification and stimulate overall economic growth. Despite the high growth rates in recent decade, Ethiopia’s overall intensification and yield levels remained below what is considered optimal. This study examines the patterns, trends, and drivers of agricultural intensification and productivity growth during the recent decade (2012 - 2019) using three rounds of representative household data collected from the four main agriculturally important regions of the country. The descriptive results indicate a positive trend in both the adoption rate and intensity of inputs and output, albeit from a low base compared to other contexts and with considerable heterogeneity by access to information, rainfall levels and variability, labor, soil quality, remoteness, among others. The econometric results show significant association between intensification, yield growth, household dietary diversity (a proxy measure for food and nutrition security), and consumer durables. However, the results on the association between current yield levels and per capita consumption expenditures are mixed (i.e., while an increase in cereal yield only improve food consumption expenditures, an increase in cash crops yield mainly improve non-food consumption expenditures). In sum, while the increasing input intensification and the resulting yield gains are associated with improvement in household diets and consumer durables, it falls short to have strong impact on incomes (as measured by total consumption expenditures), indicating that more efforts have to be made to see meaningful impacts on higher order outcomes. Additional welfare improving productivity gains through increased input intensifications may require investments to put in place appropriate fertilizer blends linked with localized soil nutrient requirements, investments to generate locally suited improved seeds and appropriate mechanisms to reach farmers, ways to mitigate production (rainfall) risk, and investments to remodel Ethiopia’s extension system to provided much needed technical support to farmers on production methods.

This book was released on 2024-07-16. Revisiting the demand and profitability of chemical fertilizers amid global fuel-food-fertilizer crisis: Evidence from Ethiopia available in PDF, EPUB and Kindle. We revisit the state of smallholder fertilizer demand and profitability in Ethiopia in the face of the recent global fuel–food–fertilizer price crisis triggered by the Russian–Ukraine war and compounded by other domestic supply shocks. We first examine farmers’ response to changes in both fertilizer and food prices by estimating price elasticity of demand. We then revisit the profitability of fertilizer by computing average value–cost ratios (AVCRs) associated with fertilizer application before and after these crises. We use three-round detailed longitudinal household survey data, covering both pre-crisis (2016 and 2019) and post-crisis (2023) production periods, focusing on three main staple crops in Ethiopia (maize, teff, and wheat). Our analysis shows that fertilizer adoption, use, and yield levels were increasing until the recent crises, but these trends seem halted by these crises. We also find relatively large fertilizer price elasticity of demand estimates, ranging between 0.4 and 1.1, which vary across crops and are substantially larger than previous estimates. We find suggestive evidence that households with smaller farm sizes are relatively more responsive to changes in fertilizer prices. We also document that farmers’ response to increases in staple crop prices is not as strong as perceived and hence appears to be statistically insignificant. Finally, we show important dynamics in the profitability of chemical fertilizer. While the AVCRs show profitable trends for most crops, the share of farmers with profitable AVCRs declined following the fertilizer price surge. Our findings offer important insights for policy focusing on mitigating the adverse effects of fertilizer price shocks.
