Book (stand-alone)Fertilizer use by crop in Ghana 2005Ghana has extensive areas of land suitable for agriculture but the soils are productive only with proper management. Traditional, soil exhausting, cultivation practices are still used extensively. The average rate of fertilizer application on most crops is low and the removal and loss of plant nutrients substantially exceed their replacement. After a period of rapid increase in the 1970s, the consumption of fertilizers started to decline in the early 1980s and only recently recovered its former level. Most crops respond economically to fertilizers and organic manure. Inadequate credit facilities, unsatisfactory produce marketing arrangements and the relatively small area receiving irrigation, despite the underutilization of several large irrigation projects, are among the identifi ed constraints to increased fertilizer use.

Book (stand-alone)Fertilizer use by crop in the Syrian Arab Republic 2003
Also available in:
No results found.About half the population of the Syrian Arab Republic depends primarily on agriculture for its livelihood and agricultural exports are a major source of foreign currency for the country. Since the 1980s, agricultural production in the Syrian Arab Republic has no longer been sufficient to meet domestic demand, which is rising as a result of population growth, generally rising incomes and urbanization. Increased fertilizer use is expected as a result of the expansion of the irrigated areas, the de velopment of fertilizer use on fodder crops and increased use on fruit crops. -

No results found.The development of the agriculture sector and improvement of the living standards of small-scale farmers are priorities of the Government of Malaysia. A higher level of agricultural production requires an increased and/or more efficient use of inputs, especially fertilizers. Fertilizer purchases by smallholder farmers are subsidized. A better use of available organic wastes, organic farming and integrated farming systems is being promoted. There is a highly competitive distribution sector for fe rtilizers. Fertilizer use in Malaysia is characterized by a large consumption of directly applied phosphate rock, attributable to the acidic nature of the soils and the large area of perennial plantation crops, and of potassium owing to the large area of oil-palm. Oil-palm is by far the largest fertilizer-consuming crop in Malaysia. In this publication, the quantities of fertilizers used on thirty crops, divided into five groups, are calculated based on recommended fertilizer rates, expected and achieved yields. Information is given on fertilizer prices, crop prices and, as an indication of the profitability of fertilizer use, the crop price: nutrient price ratios for a selection of fruit and vegetable crops.
