South Africa has a wide range of marine diversity with coastline in three oceans, two major current systems, major ocean frontal systems and benthic topography extending to a maximum depth of 5 700 m. There are 179 defined marine ecosystem types, 150 of them around South Africa and 29 around the sub-Antarctic territory of the Prince Edward Islands.
Soil quality reflects how well a soil performs the functions of maintaining biodiversity and productivity, partitioning water and solute flow, filtering and buffering, nutrient cycling, and providing support for plants and other structures. Soil management has a major impact on soil quality. Soil quality relates to soil functions. Unlike water ...
It covers environmental sciences, botany, earth sciences, physical geography, ecology, and the soil sciences of relevance to agriculture. Before the 1992 split into section B (soil and plant science) and section A (animal science), the journal was published by the Royal Swedish Academy of Agriculture and Forestry from 1950 to 1955. It was then ...
Declining soil quality is a food security concern across Africa. In Zimbabwe, once a regional breadbasket, about 70% of soils are acidic, according to the government.
Kogelberg Nature Reserve is a nature reserve of 3,000 ha (7,400 acres) comprising the Kogelberg Mountain Range, to the east of Cape Town, South Africa. With about 1600 plant species, it contains a floral diversity per unit area that is greater than anywhere else in the world. [1]
Soil microbial communities experience shifts in the diversity and composition during dehydration and rehydration cycles. [5] Soil moisture affects carbon cycling a phenomenon known as Birch effect. [6] [7] Temperature variations in soil are influenced by factors such as seasonality, environmental conditions, vegetation, and soil composition.
Soil that is healthy is fertile and productive. [29] But soil erosion leads to a loss of topsoil, organic matter, and nutrients; it breaks down soil structure and decreases water storage capacity, reducing fertility and water availability to plant roots. Soil erosion is, therefore, a major threat to soil biodiversity. [30]
Plant and Soil is a monthly peer-reviewed scientific journal covering research on the relationships between plants and soil, such as relationships and interactions of plants with minerals, water and microbes, the anatomy and morphology of roots, soil biology and ecology, etc.
