Abstract. The Biskra region in Algeria is known for the production of very good quality Deglet Nour dates. This quality is the result of the interaction of several ecological and agronomic factors. Our work aims to study the impact of hydro-edaphic parameters on the quality of Deglet Noor dates, produced in the region of Biskra. The study is carried out in three stations: Tolga, Sidi Okba and Ouled Djelel. Three farms are chosen in each station. The methodological approach is based on Soil, water, biometric and biochemical analyzes on sampled dates. The results shows that the water irrigation have a high salinity in Sidi Okba station. The statistical analyzes (ACP) shows that, the high salinity of irrigation water is the main cause of soil salinization. This salinization reduces the biometric characteristics of dates (length, width and weight), and increases their total sugar content.

In the current stage is to calculate the daily generated quantities of solid household waste, as well as to indicate the annual amounts spent on the stages of collection, transportation and landfilling of this waste, as well as to identify the practical reality of the processes and stages of solid household waste management followed by the municipal institutions of the governorate to indicate the possibility of establishing an investment project Dedicated to recycling plastic, paper and glass materials and benefiting from organic materials as fertilizers for the soil or for energy production, with the aim of activating sustainable development in the governorate.

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].
