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
FAO Soils Bulletin 43
1980Also available in:
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. -
ProjectImproving Fertilizer Utilization and Agricultural Ecological Environment in Xinjiang - TCP/CPR/3607 2020
Also available in:
No results found.Xinjiang Uygur Autonomous Region of China has exceptionally good conditions for developing organic farming, with rich resources of water, land and photothermal resources, and a unique climate. However, until now, fertilizers have been the driving force promoting the increase of agricultural products in Xinjiang. The misuse of agrochemicals over the past three decades (e.g. excessive application of fertilizers, unbalanced use of organic and mineral compounds, uncoupling of water and fertilizers) has given rise to a decreasing margin of yield growth, as well as an increased outbreak of pests and diseases, polluted and degraded water and soil; and an excessive burden on the local agricultural ecological system. Against this background, the implementation of a long-term effective fertilizer utilization technology and strategy in Changji City, Balikun County and Gongliu County in Xinjiang was a top priority issue, in order to protect the livelihoods of poor ethnic minority farmer groups, and to safeguard agricultural ecology and biodiversity in this area. The project introduced a set of improved fertilizer utilization technologies and practices, aimed at better fertilizer use structure and efficiency, and a more sustainable agricultural ecological environment, combined with interventions to increase agricultural producers’ awareness and capacity. -
Book (stand-alone)Fertilizer use by crop in South Africa 2005
Also available in:
No results found.Only fourteen percent of the total land area of South Africa receives suffi cient rainfall for arable crop production and periodic droughts affect the rainfed arable areas. The irrigated area accounts for less than ten percent of the total arable area but provides a substantial proportion of the value of the country’s total agricultural output. Governmental support and regulation of the agricultural and fertilizer sectors have been greatly reduced, resulting in the closure of some fertilizer pla nts and in marginal cereal areas being taken out of cultivation. Forty percent of the South African population lives in poverty, mostly in rural areas. An increase in the purchasing power of this sector of the population would stimulate the demand for food and indirectly for fertilizers. A proper use of fertilizers would help to improve the productivity and income of smallholders.
