Waste Cement waste (the by-product of the cement industry) is produced from  a dry and wet method for manufacturing  cement. These wastes are produced in large quantities from various cement factories that are estimated in tons thrown in the land located in different places of the country, for example, Kufa cement factory in addition to a huge amount of cement dust produced by (450Tons per day) and their influence on the environment. Therefore, a safe method must be found so that can eliminate these wastes because the by-product contains heavy metals and their oxides which are harmful to the human and to the environment especially air pollution and desertification. In this research it has been utilized these wastes as major and minor nutrients for sand soils (major nutrients Ca, K, S, Fe and small nutrients (Mn, Zn, Cu)), cement dust is added in certain proportions to the sandy desert lands. The result showed significant yields by increasing the content of sandy soil from the major and minor nutrients. This enables us to gain a safe environment and solve desertification problem which has a major cause to the environmental pollution

This study investigates the difference in the effect of magnetized water on accelerating the transport of nutrients in sandy soils and on their absorption by citrus fruits [1]. The response of the fruits to irrigation with magnetized water was estimated for three successive seasons. The results showed the effect of magnetized water on the mobility of nutrients in the root zone, which differed significantly from the element to another according to the element's ability to be magnetized . The increase in the extraction of elements from the soil as a result of magnetization was the highest possible for iron, iron extraction reached 9 times the amount of extraction in the normal case from one piece of land . Zinc increased 5 times [2], phosphorous increased 3 times and the increase in manganese was only 80%.In any case, the leaves content of manganese showed the maximum increase of this element and zinc came after it in the second place, while the content of iron in the leaves was the lowest . The leaf content of phosphorous was tripled, and for potassium the increase was significant, while for nitrogen it was not affected by magnetized water . The amount of fruits reached its maximum when the water moved to a distance of 600 meters after the magnetization device on the other hand, the magnetization device stopped causing significant changes on the water that travels for a distance of more than 700 meters [3].

The main aim of this present study is to identify and detect the land use, land cover changes occurred in the Ambo Woreda of West Shewa Zone in Ethiopia and to integrate the Remote Sensing and GIS data for analyzing and evaluating the changes in land-use of study area. Based on remotely sensed data, the Land Use Land Cover (LULC) maps and field records have been considered for investigation. Landsat7 ETM+ image of 2000 and Sentinel 2A image of 2020 are the two remotely sensed images of study area used in this study. The supervised classification based on maximum likelihood classifier in ArcGIS 10.3 has been used to identify the five major categories of LULC. The observation on the period of twenty years reveals that the agricultural land and built-up areas have stretched rapidly to the adjacent fallow lands. Also, there is significant loss in Hilly Vegetation due to settlements and industrial expansion in the fastest growing region of the Oromia Zone.
