Book (stand-alone)Technical bookEfficiency of soil and fertilizer phosphorus use
Reconciling changing concepts of soil phosphorus behaviour with agronomic information
2008Also available in:
No results found.The efficient use of fertilizer phosphorus (P) is important for three main reasons. First, phosphate rock, from which P fertilizers are manufactured, is a finite, nonrenewable resource, and it must be used efficiently in order to maximize its life span. Second, there is a need to maintain and improve the P status of many soils for the growth of crops for food, fibre and bioenergy. This is particularly important in least-developed countries (LDCs) that need to increase food production a nd improve rural livelihoods. Third, the transfer of soil P (derived from fertilizers and organic manures) is a major cause of P-induced eutrophication in surface waters. This causes undesirable changes in their ecology, resulting in a decline in the provision of eco-services, often with serious economic consequences. This report reviews, analyses and synthesizes information on the efficient use of soil and fertilizer P. It presents information on the plant availability of soil and fertilizer P, with an emphasis on soil–plant interactions. The focus is on the changing concepts of the behaviour of both soil and fertilizer P and on the need to define and assess their recovery and, thus, P-use efficiency, more appropriately. The report also outlines strategies for improving P-use efficiency. -
Book (stand-alone)Technical bookEfficient fertilizer use in summer rainfed areas 1988
Also available in:
No results found.Summer rainfall areas are extensive in the tropical and subtropical zones of the world and account for a significant proportion of world food production. they are characterized by a limited period of adequate water supply for crop growth coinciding with high summer temperatures, and they tend to supper from high evapo-transpirational loss and year to year variability in rainfall amounts. Fertilizer use would give great scope for higher crop yields.

Book (stand-alone)Technical studyFeasibility study for application of digital technologies for improved traceability and transparency along the agrifood value chains
Case studies in the Near East and North Africa Region
2023Also available in:
No results found.“Agrifood value chains of small and medium-sized producers in the Near East and North Africa region have the potential to generate more value through improved access to high-value markets. Limited logistics capacity in the region, coupled with lack of access to continuous cold chain, has resulted in weak supply chain management, high level of food loss, lack of compliance with food quality and safety standards; information asymmetries; and unfair value distribution, affecting income and livelihood of small and medium-sized producers. Improving traceability and transparency along the agrifood value chains can help building consumers' trust by better tracking the origin of food, identifying, detecting and mitigating the impact of food safety and quality issues in a timely manner and enhancing price visibility and information sharing on value distribution in each stage of the value chain. Digital technologies can play an important role in enhancing traceability and transparency by ensuring the collection of comprehensive, consistent and reliable data along the supply chain, real-time tracking, easy aggregation, integration, analysis and sharing of data. Despite the recognition of game changing potential, few studies have analysed the feasibility of application of these technologies to improve traceability and transparency of value chains, from farm-gate to market, in the region. To fill this gap in knowledge, this study was conducted to understand the digital landscape in the region, examine barriers and incentives for uptake of these technologies and to propose solutions that can improve the adoption rate and sustainability of digital technologies for small and medium-sized producers.” -
Book (series)Technical studyFinancial analysis in agricultural project preparation 1991
Also available in:
No results found.This paper grew out of a series of lectures given by the writer in April and September 1984 to FAO Investment Centre staff, mostly economists and project analysts.The paper has been written principally to meet the needs of F AO Investment Centre economists and project analysts who have no previous training in accountancy, but may be of value also to persons of a similar background working on agricultural project preparation in developing countries. Emphasis is placed on the discussion of concept s and techniques in order to provide users with an analytical framework for a systematic financial appraisal of a project. It is assumed that the user is familiar with the mathematics of discounting. The focus of the paper is on agricultural projects. The coverage is restricted to revenue-generating entities which are likely to maintain full sets of accounts, such as agro-industries, commercial farms and lending institutions. Farm budgets are thus excluded. -
Book (series)Technical studyGlobal assessment of soil carbon in grasslands
From current stock estimates to sequestration potential
2023Also available in:
No results found.Soils contribute to the achievement of the UN Sustainable Development Goals through carbon sequestration. By enhancing soil health and fertility, soils can play a crucial role in climate action, land degradation neutrality, and alleviating hunger. The present study provides a spatially explicit report on the state of grassland soils and can be used as a baseline for future work to explore the impacts of livestock management on soil carbon at regional, country and farm levels. Assessing the current state of grassland systems and their potential to sequester carbon in the soil is of key importance to understand the trade-offs between grassland services on food security, biodiversity conservation and climate mitigation.
