The effect of rock phosphate on mature coconut was evaluated from 2004 to 2010 within the context of low nut yield due to phosphorus deficiency in the acidic soils of South-Western Ghana. A low reactive Togo rock phosphate containing 25.5% P205 was applied. Three application schedules based on 666 kg/ha rock phosphate and a control …
Phosphorus (P) is an essential plant nutrient and is one of the most critical elements influencing crop production throughout the world. Phosphorus deficiency is widespread in most soils of northern Ghana, and ferruginous nodules contained in some soils in the region accentuate the deficiency problem because they act as P sinks. This research focuses …
Phosphate Rock Imports Imports into Ghana. For the third consecutive year, Ghana recorded decline in overseas purchases of phosphate rock, which decreased by -X% to X tons in 2020. Over the period under review, imports continue to indicate a drastic downturn. The growth pace was the most rapid in 2013 with an increase of X% against …
Alfisols and Ultisols of the semi-deciduous forest zone of Ghana are known to be moderately acid and very low in plant available phosphorus (P). These soils need to be fertilized to increase crop production but due to economic reasons local farmers are unable to afford water-soluble P fertilizers. Instead of expensive superphosphates, the use …
Revised Date: 16 December 2020. Publish Date: 25 February 2021. Abstract. The world's phosphate ore reserve nearly totals 69.5 billion tons (2019), but …
Millions of tons of phosphate rock are transported to the Atlantic port in El Ayoun, also situated in the Western Sahara territory, on a conveyor belt stretching 150 km in length. …
Soil phosphorus deficiency is a critical constraint in crop production in Sub-Saharan Africa (SSA). Although phosphate rock (PR) deposits have been found in the region, they have not been well-utilised due to low reactivity, limited markets, lack of effective extension systems and other factors. However, previous studies indicate that …
Field experiment was conducted at Oil Palm Research Institute, Kusi from 2002 to 2007 to as-sess the effect of Phosphate Rock (PR) on soil nutrient dynamics, growth, development and yield of oil palm. The study was carried out on the soils of Nzema series classified as Ferric Acrisols and Typic Hapludult. The oil palm trees selected were …

acidulated rock phosphate (PAPR) are possibl e alternative P sources for these soils. The rate of dissolutio n of TRP, GRP, PAPR and TSP in three benchmark soils of Ghana was assessed, and the ...
Although rock phosphate (apatite) is a cheaper source of P than the conventional more easily soluble P fertilizers (e.g. triple superphosphate [calcium dihydrogen phosphate]) (Sharif et al., 2013) explaining its less use in Pakistan, however its low solubility in calcareous soils, is a major reason for its unpopularity. Enhancing the …

Commercial fertilizer it is mostly soluble P (in the form of phosphate). Within 24 hours this soluble P starts being converted to labile P and eventually to stable P. What this means is that most of the phosphorus fertilizer you add to the soil is available to plants for a short period of time, and then it gets locked away in the soil.
