SEASONAL VARIATIONS OF SATURATED HYDRAULIC CONDUCTIVITY, PERCENTAGE POROSITY AND ORGANIC MATTER ....

In tropical soils, the wet and dry seasons not only differ significantly in terms of precipitation, moisture content, and irradiation, but they also have the ability to impact some of the major properties that distinguish distinct soil types. In 2016 and 2017, researchers studied the seasonal effects on saturated hydraulic conductivity, percentage porosity, and organic matter status in an Ultisol in Nigeria's Imo state. The study looked at four potential land uses. During the rainy and dry seasons of 2016 and 2017, samples were gathered by sampling the horizons of land uses using different profile pits dug in the land uses. Standard methods were used to prepare the samples that were collected. The results show that the saturated hydraulic conductivity of the soil varied significantly in both the rainy and dry seasons of 2016 and 2017, with the first dry season having the highest percentage of total porosity. The dry season had the lowest moisture content, while the second dry season had the greatest percentage moisture content of 17.2. In both seasons, all of the criteria tested exhibited clear changes. As a result, having a solid understanding of seasonal fluctuations in soil hydraulic characteristics will undoubtedly inform land users about potential threats to the food supply chain. By increasing the organic matter content of the soil by mulching and fallowing, land owners will be able to reduce seasonal changes.
