  • Fertilizers and Environment

    Food production remains the highest agricultural priority, subject to the constraint that it be done in harmony with nature, or at least with minimum environmental pollution. The amount of fertilizer applied can be controlled using modern application techniques, including soil and crop management, guaranteeing higher economic profit and lower ...

  • Improving Efficiency of Urea Fertilizers by Inhibition of Soil Urease Activity

    This book is a comprehensive and updated review of fundamental studies on inhibition of soil urease activity and of applied studies on improving efficiency of urea fertilizers by inhibition of soil urease activity. The general literature on these topics covers 65 years and the patent literature comprises a period of nearly 40 years. The potential ...

  • Soil fertility management in support of food security in sub-Saharan Africa (En)

    Series: Non-series TitlesThis publication reviews issues related to land degradation, with focus on problems of soil fertility management in sub-Saharan Africa. It highlights some successful experiences in the region, constraints and possible solutions specific to the major agro-ecological zones and the importance of the holistic and participatory ...

  • Soil Fertility: QUEFTS and Farmers’ Perceptions Free to Non-OECD Countries

    Soil fertility is one of many factors influencing farmers’ choices regarding agricultural production, fertilisation and soil and water conservation. However, before we can study the effects of soil fertility, we need to measure it. We use the QUEFTS model (Quantitative Evaluation of the Fertility of Tropical Soils Janssen et al, 1990) which ...

  • Is Soil Fertility Declining? Perspectives on Environmental Change in Southern Ethiopia

    The Office of Niger (ON) in Mali is one of the largest irrigation schemes in Sub-Saharan Africa and has provided a much improved source of income for rice farmers. Production in the ON has recently diversified, and farmers have started supplementing their income by growing vegetables on the rice fields in the dry season. The scheme is currently ...

  • Advances in Integrated Soil Fertility Management in sub-Saharan Africa: Challenges and Opportunities

    Food insecurity is a central concern and a fundamental challenge for human welfare and economic growth in Africa. Low agricultural production, results in low incomes, poor nutrition, vulnerability to risks and lack of empowerment. Land degradation and soil fertility depletion are considered the major threats to food security and natural resource ...

  • Economics of soil productivity in sub-Saharan Africa, (The) (En)

    Series: Non-series titlesThe increased degradation and declining fertility of sub-Saharan African soils have been recognized as critical factors in food security and poverty alleviation. This study examines the current and potential role of economic in soil productivity in sub-Saharan Africa. After examining the status of soil productivity and the ...

  • Isotopic Studies of Azolla and Nitrogen Fertilization of Rice

    Nitrogen is the most limiting element for crop production. Traditionally, expensive commercial fertilizers are used to correct soil nitrogen deficiencies. Indeed, 50% of the increase in rice yields after World War II can be attributed to increased fertilizer nitrogen use. Although an increased rate of fertilizer nitrogen application has been ...

  • Molecular Microbial Ecology of the Soil

    Grain legume crops, e.g. common bean (Phaseolus vulgaris L.), and soyabeans (Glycine max L.) are amongst the main sources of protein in Africa, Asia and Latin America. Their high protein content derive from their ability, in symbiosis with Rhizobium bacteria, to fix atmospheric nitrogen. Incorporating contributions from molecular biologists, ...

  • Stubble Over the Soil: The Vital Role of Plant Residue in Soil Management to Improve Soil Quality

    An in-depth look at no-till applications through the eyes of Chilean farmer, Carlos Crovetto. Mr. Crovetto was able to renovate his soils and obtain high wheat and corn yields using no-till and adequate fertilizers. The soil not only recuperated, but became far more productive than the original soil. This book combines a thorough treatment of the ...

  • Managing Organic Matter in Tropical Soils: Scope and Limitations

    Soil organic matter is a reservoir for plant nutrients, provides water-holding capacity, stabilizes soil structure against compaction and erosion, and thus determines soil productivity. All agriculture to some degree depends on soil organic matter. It has long been known that soil organic matter declines when land is taken into cultivation, and ...

  • Management of Biological Nitrogen Fixation for the Development of More Productive and Sustainable Agricultural Systems

    The subsistence agriculture of the pre-chemical era efficiently sustained the nitrogen status of soils by maintaining a balance between N loss and N gain from biological nitrogen fixation (BNF): the microbial conversion of atmospheric N to a form usable by plants. This was possible with less intensive cropping, adaptation of rational crop ...

  • Plant nutrition for food security. A guide for integrated nutrient management (English)

    Series: FAO Fertilizer and Plant Nutrition BulletinsFood security is a major global concern. It depends to a considerable extent on efficient plant nutrition. Extensive information on various aspects of plant nutrition has been generated in the recent past. However, this information remains scattered in several publications. This bulletin provides ...

  • Conservation agriculture. Case studies in Latin America and Africa (En)

    Series: FAO Soils BulletinsEmpirical evidence has been accumulating that sustainable intensification of crop production is technically feasible and economically profitable. Added benefits are the improvement of the quality of the natural resources and protection of the environment in currently unimproved or degraded areas, provided farmers ...

  • Amazonian Dark Earths

    Amazonian Dark Earths are not only a testament to the vanished civilizations of the Amazon Basin, but may provide the answer to how the large, sophisticated societies were able to sustain intensive agriculture in an environment with mostly infertile soils. Locally known as Terra Preta de Indio or Indian black earth, these anomalous soils are even ...

  • Tropical crop-livestock systems in conservation agriculture. The Brazilian experience (En)

    Series: Integrated Crop ManagementThis publication describes how pasture, fodder and livestock production have been integrated into conservation agriculture systems in Brazil's tropical zones. Vast areas of forest have been cleared in the tropical areas of Brazil for establishment of pastures that become unproductive once the native fertility of ...

  • Amazonian Dark Earths: Wim Sombroek´s Vision

    Amazonian soils are almost universally thought of as extremely forbidding. However, it is now clear that complex societies with large, sedentary populations were present for over a millennium before European contact. Associated with these are tracts of anomalously fertile, dark soils termed ‘terra preta’ or dark earths. These soils are presently ...
