Soil salinity has localised and regional effects on biodiversity, ranging, for example, from changes in plant composition and survival at a local discharge site through to regional changes in water quality and aquatic life. While very saline soil is not preferred for growing crops, it is important to note that many crops can grow in more saline ...
From soil analysis, it has been seen that one of the main compounds in the earth consumed by these primates is clay minerals that contains kaolinite, which is commonly used in medications for diarrheal and intestinal problems. [20] Geophagic behaviour plays an important role in nonhuman primates' health. [4]
In Africa, yield reduction is 2–40%, with an average loss of 8.2% of the continent. [8] Natural disasters: natural disasters such as mud flows, floods are responsible for the death of many living beings each year. This causes a cycle as floods can degrade soil, and soil degradation can cause floods.
In May, Kenya hosted an Africa-wide soil health summit to discuss declining production, climate change and other issues that have increased food security concerns. Agriculture is a key part of the ...
Plants and animals utilize soil for food and shelter, disturbing the upper soil layers and transporting chemically weathered rock called saprolite from the lower soil depths to the surface. [3] Terrestrial bioturbation is important in soil production, burial, organic matter content, and downslope transport.
Soil particles picked up during wind erosion of soil are a major source of air pollution, in the form of airborne particulates—"dust". These airborne soil particles are often contaminated with toxic chemicals such as pesticides or petroleum fuels, posing ecological and public health hazards when they later land, or are inhaled/ingested.
A catena in soil science is a series of distinct but co-evolving soils arrayed down a slope. [1] Each soil type or "facet" differs somewhat from its neighbours, but all occur in the same climate and on the same underlying parent material. A mature catena is in equilibrium as the processes of deposition and erosion are in balance.
