- Abstract
Tabuk region is one of the largest regions in Saudi Arabia in terms of area. The most important challenges that can face agriculture in the region are weeds and environmental damage resulting from human activities. This study was prepared to know the relationship between the physical and chemical components of soil and the spread of weeds in the farms of the region. So field trips were conducted to the study area, then the area was divided into 4 sites, each site was divided into three parts, then divided into ten squares with an area of 1 m² . The plant species were identified and named according to the flora books of Saudi Arabia. A total of 65 samples with an amount of 1 kg of soil were collected to a depth of one foot from more than one location. The correlation between the distribution of study sites on the coordination axes (CCA), and the first axis (AX1) was positive with the phosphorous element (r = 0.58). The second axis showed a positive correlation with chlorine (r = 0.46) and calcium (r = 0.42), and a negative correlation with each of the soil organic matter (r = -0.62), soil pH (r = -0.65). The third axis also showed a negative correlation with HCO3 bicarbonate (r = -0.69) and EC (r = 0.42). The distribution of plants and their relationship to soil factors showed that there are ten plant species whose presence is associated with phosphorous. Multi-dimensional analysis trends for locations and plant species in the study area in Tabuk region using the TWA program TWINSPAN, Coordination (DCA: DECORANA) led to the division into four plant communities and their distribution was related to soil properties.
