Описание: The ability of soil to sustain agricultural plant growth is referred to as soil fertility. A soil that is fertile has the ability to supply essential plant nutrients and water in appropriate amounts for the growth and reproduction of plants. It is also free of the toxic substances which could inhibit the growth of plants. A natural or synthetic material which supplies nutrients to plants which are essential for their growth is termed as a fertilizer. They generally provide macronutrients such as nitrogen, phosphorous and potassium in varying proportions. Fertilizers are broadly classified into single nutrient and multinutrient fertilizers. The topics included in this book on soil fertility and fertilizers are of utmost significance and bound to provide incredible insights to readers. Different approaches, evaluations, methodologies and advanced studies on this field have been included in it. This book will serve as a reference to a broad spectrum of readers.

Описание: 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.This book presents methods for enhancing the efficiency of fertilizer that can reduce the environmental footprint.
As part of its efforts to improve fertilizer use and efficiency in West Africa, and following the recent adoption of the West African fertilizer recommendation action plan (RAP) by ECOWAS, this volume focuses on IFDC's technical lead with key partner institutions and experts to build on previous and current fertilizer recommendations for various crops and countries in West Africa for wider uptake by public policy makers and fertilizer industry actors.
Описание: The United Republic of Tanzania has a predominantly agricultural economy, with agriculture accounting for more than two-thirds of employment in rural areas and representing 30 percent of GDP. Yet, by global standards and even by the standards of Developing Countries, crop yields in the county are low. Using improved seeds and mineral fertilizers is therefore critical to promoting growth in crop productivity, food production and sustaining the natural resource base, especially among the smallholder farmers who subsist on nutrient-poor soils.
In 2016, The Ministry of Agriculture, Livestock, and Fisheries (MALF) of the United Republic of Tanzania requested an assessment of the potential costs and benefits of a proposed Bulk Procurement System (BPS) for fertilizer imports that would consolidate international procurement to save costs, ultimately improving the affordability for farmers. This assessment was jointly carried out and submitted to MALF in 2017 by FAO and the International Fertilizer Development Centre (IFDC), and presents an analysis of the fertilizer market, the proposed BPS policy, and interviews with over one hundred public, private, and civil society stakeholders. The findings indicate that the proposed system would likely not reduce prices for farmers and could negatively affect availability and market competition – causing prices to increase in the long term. The authors therefore recommend against its implementation pending further consultations, or to pilot the system with careful review and evaluation. The report also presents alternative policy options for the short and medium term to improve overall efficiency in the value chain and ultimately make fertilizer more affordable for Tanzanian smallholder farmers.

Описание:
Controlled Release Fertilizers for Sustainable Agriculture provides a comprehensive examination of precision fertilizer applications using the 4-R approach--the right amount of fertilizer at the right time to the right plant at the correct stage of plant growth. This volume consolidates detailed information on each aspect of controlled release fertilizers, including up-to-date literature citations, the current market for controlled release fertilizers and patents. Presenting the tremendous advances in experimental and theoretical studies on sustainable agriculture and related areas, this book provides in-depth insight into state-of-the-art controlled release mechanisms of fertilizers, techniques, and their use in sustainable agriculture.
Conventional release mechanisms have historically meant waste of fertilizers and the adverse effects of that waste on the environment. Controlled release delivery makes significant strides in enhancing fertilizer benefit to the target plant, while protecting the surrounding environment and increasing sustainability.

Описание: The fertilizers can play an important role in managing soil fertility. This book presents the concept of fertilizers and their utility in crops. This book provides an impetus towards learning crop science that can be of fertilizers. The concept of the preparation of fertilizers and their use in the crop systems is illustrated. This book can help all science students who are interested in fixing their careers for agriculture research and development. This can also serve as a handbook for researchers and other academic communities.
