Book (stand-alone)Fertilizer use by crop in Cuba 2003
Also available in:
No results found.In this study the agro-ecological structure and the areas, yields and fertilization of the individual crops in Cuba are examined. All Cuba’s fertilizer requirements are imported and the quantities available are limited. The use of fertilizers fell by 80 percent during the 1990s and the present level is insufficient to maintain yields and soil fertility. In order to alleviate the situation the Government gives priority to certain key crops such as sugar cane because of its economic importance and potatoes as a key food crop. The use of plant nutrients from organic sources is encouraged. The use of biofertilizers has been tried but only nitrogen-fixing Rhizobium has maintained its position. -

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.
