Abstract. Soil phosphate represents the only source of phosphorus for plants and, consequently, is its entry into the trophic chain. This major component of nucleic acids, phospholipids, and energy currency of the cell (ATP) can limit plant growth because of its low mobility in soil.

· When underground mining became uneconomical, black phosphate mines were simply left abandoned and in the nineties, the underground exploitation in Youssoufia gave way to open-pit mining. In 1979, OCP began open-pit phosphate exploitation in the Benguerir mine site which is considered the most recent of the four mine sites in Morocco.

· Data mining is not another hype. Instead, the need for data mining has arisen due to the wide availability of huge amounts of data and the imminent need for turning such data into useful information and knowledge. Thus, data mining can be viewed as the result of the natural evolution of information technology.

Phosphate Works. One of Israel's major mining industries is the exploitation of the phosphates in the Negev Desert. For decades the Negev Phosphate Works have been removing these materials by open-pit mining. The result has been the creation of a desolate landscape of huge holes with adjacent waste heaps some 40 meters high.

· Strip mining is commonly used for mining coal seams and phosphate beds. In hilly terrain the mining of the overburden and the deposit (usually a coal seam) follows the contour around the hill and into the hillside up to the economic limits; hence it is called contour mining.

Phosphate (Pi) is a macronutrient that is essential for plant growth and development. However, the low mobility of Pi impedes uptake, thus reducing availability. Accordingly, plants have developed physiological strategies to cope with low Pi availability. Here, we report that the characteristic Arab …
