Podzols form under forested landscapes on coarse parent material that is high in quartz. They have a characteristic subsurface layer known as the spodic horizon made up of accumulated humus and metal oxides, usually iron and aluminum. Where are podzol soils found? These soils are found where there is goodRead More →
The soils of Maharashtra are residual, derived from the underlying basalts. In the semi-dry plateau, the regur (black-cotton soil) is clayey, rich in iron, but poor in nitrogen and organic matter; it is moisture-retentive. Is laterite soil found in Maharashtra? In India, laterite soil is widespread, covering over 10% ofRead More →
Environmental impacts of tobacco farming include massive use of water, large-scale deforestation, and contamination of the air and water systems. Many countries that grow and/or produce tobacco are low- or middle-income countries and some of them face substantive food insecurity, and even hunger. Is growing a tobacco plant illegal? IsRead More →
Regolith on Earth originates from weathering and biological processes. The uppermost part of the regolith, which typically contains significant organic matter, is more conventionally referred to as soil. What is regolith also known as? Lunar regolith (also known as lunar soil) is the loose material ranging in size from dustRead More →
Premium Soil Conditioner is immediately functional in the soil and results are visible in one season. What do soil improvers do? Soil improvers are substrates that improve soil structure and soil fertility. Soil improvers have to be mixed through the upper layer of the garden, in the root zone ofRead More →
Cow manure has an acidifying effect on soils. When aged cow manure is incorporated into clay soils, it can increase the already acidic soil to levels that will not support healthy plant development. Adding manure to alkaline soils can increase the soil’s acidity over time and help plant development. IsRead More →
Fruiting vegetables, like tomatoes, are least likely to contain lead absorbed from soil. The study found that adding organic matter—like compost—to soils changes the absorption of lead. Do plants use lead? Despite its lack of essential function in plants, lead is absorbed by them mainly through the roots from soilRead More →
Four Causes of Soil Erosion Water. Water is the most common cause of soil erosion. … Wind. Wind can also make soil erode by displacing it. … Ice. We don’t get much ice here in Lawrenceville, GA, but for those that do, the concept is the same as water. …Read More →
podzolic soil, podzolic also spelled podsolic, also called lessivé soil, soil usually forming in a broadleaf forest and characterized by moderate leaching, which produces an accumulation of clay and, to some degree, iron that have been transported (eluviated) from another area by water. What is the texture of podzol soil?Read More →
Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Activities that remove vegetation, disturb the ground, or allow the groundRead More →
