Being very reactive, the Gafsa and Tilemsi PRs dissolved rapidly and their effectiveness remained unchanged or increased slightly after 4 months, while less-reactive PRs required time to express their potential effectiveness. ... The National Reactive Phosphate Rock Project from Australia provides a valid example of such a programme (Sale et al ...

This work aims to identify, isolate and characterize Tilemsi rock phosphate (TRP) solubilizing Thiobacillus strains in various agricultural soils. Obtained results showed that the analyzed soils are poor in Thiobacillus and that the quantity of acid produced and TRP solubilized is directly proportional to the growth of these bacteria.

Tilemsi Rock phosphate Tilemsi (TRP), is a good and inexpensive alternative to imported phosphate fertilizers. Thiobacillus thioparus, Thiobacillus thiooxidans and Thiobacillus ferooxidans, are known for their ability to oxidize soil sulfur and sulfides and influence the solubilization of inorganic phosphates. These bacteria have …

With the broad aim of biologically improving P uptake by wheat fertilized with Tilemsi phosphate rock (TPR), we investigated the effect of inoculation with TPR-solubilizing …

Phosphorus deficiency is known as one of the major constraints to crop production in West Africa. Farmer-managed trials were conducted in three agroecological zones of Mali to evaluate the profitability of Tilemsi phosphate rock (TPR) in different crop-rotation systems in comparison with conventional water-soluble fertilizers. Marginal analyses were used to …

The use of phosphate rock (PRs) emerges as a more sustainable alternative for agriculture. The aim of this work was to isolate phosphate rock-solubilizing bacteria (PRSB) from maize mycorrhizosphere, having growth promoting traits and that will be arbuscular mycorrhizae fungi (AMF) compatible. ... The Tilemsi PR contained less Ca, …

Biological system for improving the availability of Tilemsi phosphate rock for wheat (Triticum aestivum L.) cultivated in Mali

The objective of this study was to assess the combined effects of Tilemsi rock phosphate (PNT) with different doses of soluble fertilizers on the solubility of rock phosphate, the agronomic performance of sorghum and the chemical properties of the soil. The study consisted of the comparison of four (4) types of fertilization at three (3) levels ...

open access. Abstract. Phosphorus (P) is vital for plant growth. However, most added soluble P forms insoluble phosphates. Therefore, inorganic P (Pi) accumulates in …

The Tilemsi phosphate rock (TPR) of Mali is a good and cheaper alternative to imported phosphate fertilizers. Many soil microorganisms can also mobilize sparingly soluble inorganic phosphates, and several have a good potential to improve plant growth. With the aim of improving the response of wheat cultivated in Mali to fertilization with …

Phosphate fertilizers are dependent on phosphorus derived from phosphate rock, which is a non-renewable resource and current global reserves may be depleted in 50–100 years (Cordell et al., 2009). Therefore, exploring alternative forms of agriculture, where nutrient conservation is key, is of vital importance. ... Effect of Tilemsi phosphate ...

Characterization of Some Agricultural Soils: Presence and Activity of Tilemsi Rock Phosphate-Solubilizing Thiobacilli

the local Tilemsi phosphate rock (TPR) deposits supply the farmers with a cheaper alternative (Bationo et al. 1997). Many soil microorganisms, including bacteria and fungi, are able to mobilize sparingly soluble inorganic and organic phos-phates, and they have an enormous potential in providing soil phosphates for plant growth (Rich-

However the Tilemsi phosphate rock (TPR) deposits are estimated to be between 20 and 25 million tonnes, and are a potential inexpensive source of P for farmers (Bationo et al., 1997).

Phosphate-solubilising microorganisms have been studied widely in alkaline and calcareous soils (Wakelin et al., 2007; Meyer et al., 2017), where acidification is considered as a key mechanism for P solubilisation. Acidification leads primarily to the dissolution of Ca-P minerals, which more commonly occur in higher pH soils.
