Book Description
World Bank Technical Paper No. 408. This report is a critical review of the technical, economic, and institutional constraints on improving soil fertility in Sub-Saharan Africa, and the actions recommended to address them. Action plans prepared for Ghana, Kenya, Malawi, and Mali examine the demand for and supply of mineral fertilizers, the exploitation of local mineral resources, the prevention of soil erosion and increasing soil-water retention, and soil fertility management using organic technologies and management practices.

Book Description
Nutrient-balance assessments are valuable tools for delineating the consequences of farming on soil fertility. Various approaches and methods for different situations have been used in the past. This bulletin presents a state-of-the-art review of nutrient balance studies. It brings out the evolution of the approaches and methods, provides for comparisons among them, features the improvements made, and highlights remaining issues. This analysis will be useful in further development of the assessment methodologies as reliable tools for devising time-scale soil fertility management interventions.

Book Description
Recent micro level data from East Africa is used to benchmark aggregate data and assess the role of agricultural inputs in explaining variation in crop yields on smallholding plots. Fertilizer, improved seeds, protection against erosion and pesticides improve crop yields in Rwanda and Ethiopia, but not Uganda, possibly associated with lack of use there. With all positive yield determinants in place, wheat and maize yields could increase fourfold. The data hints at the negative effect of climate change on yields and the benefits of accompanying measures to mitigate its adverse impact (access to finance and protection against erosion). The adverse effect of crop damage on yields varies between 12/13 percent (Rwanda, Uganda) to 36 percent (Ethiopia). Protection against erosion and investment financing mitigate these effects considerably.

Book Description
This publication provides practical guidelines on establishing composite service laboratories for the analysis of soil, plants, water and fertilisers (mineral, organic and biofertilisers). It also provides various analytical methods for assessing soil fertility and making nutrient recommendations, assessing quality of irrigation water, and details of the equipment, chemicals and glassware required for a given analytical capacity. Useful to administrators and planners in establishing laboratories, and to technicians through providing detailed and precise procedures for estimation.

Book Description
Africa can achieve self sufficiency in food production through adoption of innovations in the agriculture sector. Numerous soil fertility and crop production technologies have been generated through research, however, wide adoption has been low. African farmers need better technologies, more sustainable practices, and fertilizers to improve and sustain their crop productivity and to prevent further degradation of agricultural lands. The agricultural sector also needs to be supported by functional institutions and policies that will be able to respond to emerging challenges of globalization and climate change.

Book Description
Rhizosphere Engineering is a guide to applying environmentally sound agronomic practices to improve crop yield while also protecting soil resources. Focusing on the potential and positive impacts of appropriate practices, the book includes the use of beneficial microbes, nanotechnology and metagenomics. Developing and applying techniques that not only enhance yield, but also restore the quality of soil and water using beneficial microbes such as Bacillus, Pseudomonas, vesicular-arbuscular mycorrhiza (VAM) fungi and others are covered, along with new information on utilizing nanotechnology, quorum sensing and other technologies to further advance the science. Designed to fill the gap between research and application, this book is written for advanced students, researchers and those seeking real-world insights for improving agricultural production. - Explores the potential benefits of optimized rhizosphere - Includes metagenomics and their emerging importance - Presents insights into the use of biosurfactants

Book Description
Soil and Fertilizers: Managing the Environmental Footprint presents strategies to improve soil health by reducing the rate of fertilizer input while maintaining high agronomic yields. It is estimated that fertilizer use supported nearly half of global births in 2008. In a context of potential food insecurity exacerbated by population growth and climate change, the importance of fertilizers in sustaining the agronomic production is clear. However, excessive use of chemical fertilizers poses serious risks both to the environment and to human health. Highlighting a tenfold increase in global fertilizer consumption between 2002 and 2016, the book explains the effects on the quality of soil, water, air and biota from overuse of chemical fertilizers. Written by an interdisciplinary author team, this book presents methods for enhancing the efficiency of fertilizer use and outlines agricultural practices that can reduce the environmental footprint. Features: Includes a thorough literature review on the agronomic and environmental impact of fertilizer, from degradation of ecosystems to the eutrophication of drinking water Devotes specific chapters to enhancing the use efficiency and effectiveness of the fertilizers through improved formulations, time and mode of application, and the use of precision farming technology Reveals geographic variation in fertilizer consumption volume by presenting case studies for specific countries and regions, including India and Africa Discusses the pros and cons of organic vs. chemical fertilizers, innovative technologies including nuclear energy, and the U.N.’s Sustainable Development Goals Part of the Advances in Soil Sciences series, this solutions-focused volume will appeal to soil scientists, environmental scientists and agricultural engineers.

Book Description
Agricultural input subsidies are a prominent feature in the 2018-2024 Strategic Plan for Agricultural Transformation (PSTA 4), which is designed and implemented by the Ministry of Agriculture and Animal Resources (MINAGRI). By reducing the cost of improved seed and inorganic fertilizers, subsidies are designed to accelerate the use of these productivity-enhancing inputs, thereby increasing agricultural yields and output, increasing rural incomes while reducing food prices, and improving food security in line with PSTA 4’s targets. However, questions arise about whether the current input subsidy rates and levels are sufficient to increase crop production and meet the PSTA 4 targets, and whether the subsidy system can be expanded in the current economic climate and fiscal situation caused by the COVID-19 pandemic and spike in global fertilizer prices. This paper examines the impact of an increase in the price of fertilizer in Rwanda using seasonal production data from National Institute of Statistics of Rwanda (NISR) in a microsimulation model aimed at three priority crops—maize, rice, and Irish potato—and the three main fertilizers in use—diammonium phosphate (DAP), urea, and NPK.
