Extensive research on the agronomic potential and actual effectiveness of phosphate rocks (PRs) as sources of phosphorus has been carried out in Africa, Asia, Latin America and elsewhere. This publication brings together a wide range of available information on key issues regarding the use of PRs in agriculture, including world deposits; characteristics of sources; evaluation methodologies for direct application of PR (DAPR); analysis of biophysical and farming factors; development and use of decision-support systems for DAPR; soil P testing for PR application; available technologies for enhancing the agronomic effectiveness of indigenous PR sources; environmental issues; legislation guidelines; and future research priorities.

Agriculture is primarily the uppermost important sector in Sudan, contributing significantly to the country’s national economy. However, in spite of the country’s vast cultivated area, productivity remains very low. The declining agricultural production is indicative of the need for adopting sustainable agricultural development approaches to the achieve country’s food security. The attainment of sustainable agricultural production will require the proper use of all available resources such as land, water, and mineral resources, including the phosphate rock reserves. Rock phosphate deposits of potential economic value occur at more than a hundred locations in sub-Saharan African countries, including Sudan. Several geological surveys in Sudan have proven the occurrence of abundant resources of phosphate deposits in different locations in the country. For advocating the initiation of rock phosphate mining and phosphate fertilizer industry in Sudan, this book delivers sufficient and validated information on the underutilized resource of rock phosphate in Sudan and exposes its potential role in the development of sustainable agricultural production. The book presents an accurate image of the current status and prospective scenario in relation to rock phosphate deposits and the potential establishment of the fertilizer industry in Sudan. The book presents a comprehensive literature review on the history, advantages, and impacts of using rock phosphate. It also sheds light on the rock phosphate deposits in Sudan, their locations, and geological and agricultural quality as compared to rock phosphate from other global resources. The book presents two detailed case studies on assessing the agronomic value of Kurun and Uro rock phosphate rocks as fertilizers and their environmental impact assessment. The book then highlights the potential benefits of phosphate mining and the initiation of the phosphate fertilizer industry in Sudan, proposes a plan for achieving that goal, and presents recommendations to bring the Sudanese phosphate fertilizer industry to life.

This book presents recently-developed crop, soil, and management practices that can be used to improve phosphorous use efficiency in agriculture. Food security highly depends on the availability of plant nutrients such as phosphorus, yet rock phosphate reserves are expected to be exhausted in the next 50–100 years. Moreover, about 80% of the phosphorous fertilizers applied to soils become unavailable to plants due to phosphorous fixation in iron and aluminum oxides in acidic soils and with carbonates in alkaline soils. As a consequence, only 10-15% of applied phosphorous is up taken by crops. Therefore, there is a need for advanced practices for improving phosphorus use efficiency.

Phosphorus (P) stands second to nitrogen in terms of its essentiality as a plant macronutrient, as well as due to its involvement in almost all plant developmental stages, primary and secondary plant metabolisms, maintenance of membrane structures, and in the structural skeleton of major biomolecules. An optimum P-supply also helps plants combat abiotic stress impacts. Most P in soil remains unavailable for uptake by plants. P-containing fertilizers are being added to agricultural lands to sustain high yields. Only the least amount of the applied P (20%–30%) is used by most cultivated plants, and the rest remains as legacy P (P surpluses), which eventually causes eutrophication. This book, Phosphorus in Soils and Plants, reviews P in soils and plants, P dynamics in the soil–water–sediment environment, the major roles of P in the photosynthetic dark phase-biochemical pathways, major approaches for the sustainable management of P in agriculture, main mechanisms underlying the role of P in the regulation of plant–microbe interactions in the rhizosphere, literature on the role of microbial phosphate solubilization in management of soil and plant nutrients, and insights into P recovery through waste transformation. This volume is an important resource for plant biologists involved in teaching or research who wish to advance their knowledge of P in soils and plants.

Phosphorus is an essential plant nutrient, but global population growth has dramatically reduced the availability of phosphorus fertilizer resources. Despite this scarcity, there remain numerous problems associated with the excessive and inappropriate use of phosphorus leading to non-point source pollution and eutrophication of natural waters. Identifying appropriate systems for managing soil phosphorus and reducing the risks of eutrophication are needed to minimize the environmental risks. This book focuses on the availability and recycling of phosphorus; regulatory and policy issues of sustainable phosphorus use; and water quality management in agroecosystems pertaining to phosphorus. Sections are dedicated to global phosphorus reserves; cycling and pathways of phosphorus; phosphorus in agriculture; human dimensions and policy intervention; and research and development priorities. Phosphorus is a finite but crucial resource and is an essential element to all life. Sub-optimal availability and nutrient imbalance in the root zone can adversely impact plant growth, and the quality of food and feed grown on these soils. However, the proven reserves of phosphorus can hardly be adequate for a few centuries only. Yet, its misuse and mismanagement has caused severe problems of eutrophication of water and pollution of the environment. Thus, judicious management of soil phosphorus is essential. This volume is specifically devoted to availability and recycling of phosphorus, regulatory/policy issues of sustainable use of phosphorus, and management in agroecosystems in the context of maximizing the use efficiency and minimizing the environmental risks of water quality.

Sustainability of agricultural systems is a major global concern due to population growth and a number of environmental factors. This book addresses the key to the development of sustainable agriculture-management of soil fertility. Combining data from temperate and tropical regions, it presents a complete picture of how various soils can best be managed under widely different environmental conditions. Soil Fertility Management for Sustainable Agriculture is an excellent reference for environmental and agricultural professionals as well as a textbook for undergraduate and graduate students preparing for a career in agriculture or soil fertility management.
