Registered nursing is a large and diverse field. Its 2.7 million practitioners range from novice staff nurses to seasoned clinicians and administrators with decades of experience.
Most clay soil is considered alkaline; clay soils typically have a pH range between 7 and 8.5. In order for soil to be considered acidic, the pH levels must be below 7.

environments, soil pH decreases over time in a process called soil acidification, due to leaching from high amounts of In dry climates, rainfall. however, soil weathering and leaching are less intense and pH can be neutral or alkaline. Soils with high clay and organic matter content are more able to resist a drop or rise in pH have a (greater buffering capacity) than sandy soils. Although clay content cannot be modified, organic matter content can be changed by management. Sandy soils commonly have low organic matter content, resulting in alow buffering capacity , high rates of water percolation and infiltration making them more vulnerable to acidification . Soil pH Management Soil pH is affected by land use and management. Vegetation type impacts soil pH. For example, areas of land foresttend to be more acidic than. areas of Conversion of land from grassland. forestland or grassland to cropland can result in. drastic pH changes after a few years.
