STATISTICAL ANALYSIS OF SOIL CHEMICAL PROPERTIES In Al-Ansar district in Salah Al-Din Governorate Republic of Iraq

Abstract

This study was conducted on the cultivation of the grape crop, which is characterized by Al-Ansar sub-district of Salah Al-Din Governorate. This area is characterized by the peculiarity of its cultivation and production of this crop for a long time. The area of agricultural land allocated for this crop is (23) thousand dunums, and it includes (7) sectors distributed sparsely and with different agricultural areas among them, as well as different in their production, as shown through the study. It was summarized to research on two provinces as a model for other provinces, geographical factors. Both natural and human have a distinct role in the production of this crop. Of the natural factors, light, temperature, radiation, humidity, rain, wind, frost, and dust were studied. In addition to other natural factors related to soil and water on the physical and chemical sides. The most important diseases affecting grapes and methods of their treatment were listed in one of the chapters of the treatise. Concentrations of negative anions (chloride, sulfate, bicarbonate, carbonate, nitrate, phosphate, electrical conductivity, total dissolved salts), positive cations, and other characteristics (calcium, magnesium, sodium, ionic exchange capacity, soil reaction function, organic matter). Field and recent information was distributed to (280) farmers, not counting the information and classifying it accurately about the grape crop. The laboratory aspect is very clearly visible by reviewing the results. Soil and water samples collected from the study area were analyzed in the soil and water laboratories. The statistical aspect is also clearly prominent, as the experimental design method was used for the first time, from which (complete random sectors) were chosen. In addition to that, other statistical coefficients such as correlation coefficients to clarify the nature of the relationship between the study factors. We can point out the most important and prominent results that have been reached, which are: Through what has been discussed, it was found that the cultivation of grapes in Iraq dates back to a very ancient time. In addition to its nutritional benefits, it was found that it has great medical benefits, as indicated by ancient carvings and modern laboratory analyzes,The process of propagating grapes is done in two ways, either by layering or by cuttings, which is the most successful as it preserves the strain and quality of grapes.Chemical properties also have the most prominent goal in influencing the amount of production and its distribution, especially (calcium and magnesium salts, organic matter, sulfates, dissolved salts).
