FAO Fertilizer and Plant Nutrition Bulletin
Author: Efficiency of Soil and Fertilizer Phosphorus Use
Author: John Keith SyersPublisher: Fao Fertilizer and Plant Nutri
ISBN: 9789251059296
Category : Science
Languages : en
Pages : 130
Book Description
The efficient use of phosphorus (P) is essential to many agricultural and environmental issues. This bulletin 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.

Languages : en
Pages : 128
Book Description
Most of the world's hunger and poverty occurs in rural areas. The use of fertilizers could improve agricultural productivity in these areas. However, many developing countries attach a low priority to the subsistence / smallholder sector, particularly in disadvantaged areas. This publication summarizes the information from 21 countries: the crops on which fertilizers are used, the social and structural context, appropriate fertilizer application rates and their profitability, arrangements for supplying fertilizers to farmers and for marketing their produce, credit facilities, and research.

Assessment of Soil Nutrient Balance
Author: Rabindra N. RoyPublisher: Food & Agriculture Org.
ISBN: 9789251050385
Category : Science
Languages : en
Pages : 104
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.
Scaling Soil Nutrient Balances
Author: Food and Agriculture Organization of the United NationsPublisher: Food & Agriculture Org.
ISBN: 9789251052372
Category : Business & Economics
Languages : en
Pages : 152
Book Description
Using data on three countries in sub-Saharan Africa, this report compares macro- and microlevel approaches to determine soil nutrient balances with an innovative mesolevel approach. It highlights the added value that a mesolevel approach can provide in terms of its usefulness to mesolevel stakeholders in articulating and targeting scale-specific soil fertility enhancing measures, and its validity as an entry point for policy-makers and private-sector intervention. Contains numerous color figures and tables.
