Book (stand-alone)Improved use of Plant Nutrients. Report of the Expert Consultation on Better Exploitation of Plant Nutrients, Rome, 18-22 April 1977

No results found.FAO organized an Expert Consultation in April 1977 with participants from countries consuming both a high and low quantity of fertilizer, to identify possibilities for a more intensive and rational utilization of the valuable plant nutrients in mineral and organic fertilizers, with emphasis on conditions in developing countries. The conclusions reached should serve interested countries as a guide for follow-up activities in the more rational use of plant nutrients at the research and practical l evel. The participants were convinced that there are still ample possibilities for improvement and for making the costly and sometimes scarce plant nutrients more efficient and their use more economic. -
Book (stand-alone)Plant nutrition for food security - A guide for integrated nutrient management 2006

No results found.Of the essential material needs of humankind, the basic requirement is for an adequate supply of air, water and food. People have free access to the air they breathe. However, access to drinking-water and food, while easily obtained for some, is difficult for many. In addition to being physically available, these materials should also be of acceptable quality and continuously so. Hunger and diseases have affected humankind since the dawn of history. Throughout time, there have been p eriods of famine leading to suffering and starvation, making the fight against hunger and the diseases caused by malnutrition a permanent challenge. For many centuries until about 1800, the average grain yield was about 800 kg/ha, providing food only for a few people. The main problems were the low fertility of most soils (mainly caused by the depletion of nutrients) and the great yield losses from crop diseases and pests. -
Book (stand-alone)Organic recycling in Africa. Papers presented at the FAO/SIDA Workshop on the Use of Organic Materials as Fertilizers in Africa, Buea, Cameroon, 5-14 December 1977

No results found.Policy makers as well as scientists have started to acquire an honest appreciation of the possibilities of reducing the wastage of materials which could be profitably utilized for improving or maintaining soil productivity. In addition, the great opportunities offered by making more efficient use of the potentials of biological nitrogen fixation in farming systems are now fully recognized. A number of recommendations and suggested guidelines were made by the various Working Groups during the t wo-week Workshop. These covered: 1- Cropping systems and crop residue management 2- Biological N-fixation 3- Research, training and extension. A central theme much emphasized at the Workshop was the fact that agricultural policy makers, technicians and scientists need to study more closely the basic practices of the small farmers so that proposal for the introduction of new systems could be easily understood, integrated and accepted by these farmers.
