Download or read book Mismatch between soil nutrient requirements and fertilizer applications: Implications for yield responses in Ethiopia written by Abay, Kibrom A. and published by Intl Food Policy Res Inst. This book was released on 2021-06-28 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This document examines fertilizer use and marketing to small farmers in the Dominican Republic. The effort was not intended to be an in-depth country study. It was designed to assemble secondary data and opinions of those knowledgeable of the Dominican Republic small farm and fertilizer situation and to organize that data for planning purposes by the USAID Mission to the Dominican Republic and the Dominican Republic Government in developing fertilizer-related action programs designed to increase the domestic food supply.

Download or read book Improving Potassium Recommendations for Agricultural Crops written by T. Scott Murrell and published by Springer Nature. This book was released on 2020-12-14 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book highlights concepts discussed at two international conferences that brought together world-renowned scientists to advance the science of potassium (K) recommendations for crops. There was general agreement that the potassium recommendations currently in general use are oversimplified, outdated, and jeopardize soil, plant, and human health. Accordingly, this book puts forward a significantly expanded K cycle that more accurately depicts K inputs, losses and transformations in soils. This new cycle serves as both the conceptual basis for the scientific discussions in this book and a framework upon which to build future improvements. Previously used approaches are critically reviewed and assessed, not only for their relevance to future enhancements, but also for their use as metrics of sustainability. An initial effort is made to link K nutrition in crops and K nutrition in humans. The book offers an invaluable asset for graduate students, educators, industry scientists, data scientists, and advanced agronomists.

Download or read book Agricultural Research for Sustainable Food Systems in Sri Lanka written by Ranjith Premalal De Silva and published by Springer Nature. This book was released on 2020-10-06 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food systems involve a range of activities concerning food production, processing, distribution, marketing and trade, preparation, consumption and disposal. They encompass the path of food from the farm to the dinner table, meeting the food and nutritional needs of a nation. When such systems do so without sacrificing the needs of future generations, they are referred to as “Sustainable Food Systems.” The natural and physical environment, infrastructure, institutions, society and culture, and policies and regulations within which they operate, as well as the technologies they adopt, shape these systems’ outcomes. Making food systems more sustainable is a key priority for all nations, and Sri Lanka is no exception. Food systems deliver optimal performance when the policy and regulatory environment is conducive, institutions are supportive, and a combination of agricultural research investments and an efficient extension system generates the technologies and scientific evidence required for sound policymaking and agenda setting. Further, agricultural research can generate essential findings, technologies and policies for sustainable agricultural development – across disciplines, sectors and stakeholder groups. This book shares valuable insights into research conducted in the broad food and agriculture sectors in Sri Lanka. It also discusses the status quo in related disciplines, and outlines future research directions. Accordingly, it offers a valuable source of reference material for researchers, students, and stakeholders in the food and agriculture sectors, while also highlighting the types of support that policymakers and other decision-makers can provide.
