What are heavy soil and light soil?
Heavy soils are heavy, high in nutrients and wet like the clay soil. Light soils are light, dry, warm,low in nutrients and often acidic.
Why are many tropical soils poor in nutrients?
heavy rains in this climate zone can remove, or leach, nutrients from the topsoil.
Soil formation in the rainforest?
The top soil of the rainforest doesnt contain many nutrients, and the top soils minerals are washed away with the soil due to rainfall. The plants are adapted to the soil by them containing nutrients within themselves, therefore not needing soils rich in nutrients and minerals.:)- that's all i know.....
What are the properties of Georgia red clay?
Georgia's red soils are old soils that have been leached of nutrients by weathering. The high acidity is due to this leaching of previously existing bases by rainwater hydraulics, leaving a high silica content product that is also high in iron oxides, resulting in the reddish color. Red soils contain little organic matter. Plants that grow on red soils generally draw nutrients from organic material that is sitting on top of the soil layer.
What depleted the soils?
Overproduction of single crops, such as cotton or tobacco, drained the land of the nutrients needed to maintain soil fertility.
Do Tropical soils contain lots of nutrients?
No, they do not. They are "old soils" and contain very few nutrients.
Why do clay and organic soils hold nutrient better then sandy soils?
Clay and organic soils hold nutrients better then sandy soils because the sandy soils as the water drains away, the water will carry the nutrients with it. This is called leaching and the nutrients will not be available for the plants to use.
How can clear-cut ecosystems release more nutrients into surface streams?
Because soils have nutrients in them and if they clear it out, the soils doesn't have to share any nutrients.
Why clay soil are fertlie than sandy soil?
Clay soils hold more nutrients, while sandy soils quickly have their nutrients leached by rain.
What soil contains most nutrients?
Some clays and particularly organic soils (like humus) hold nutrients and water much better than sandy soils do. the soil that contains the most nutrients is the loam.
How do you fertilise sandy soil?
You should either fertilize sandy soils with slow release fertilizers, like organic fertilizers, or add nutrients slowly with irrigation water. Sandy soils have less ability to hold nutrients than other soils, and soluble nutrients can leach out very quickly.
What nutrients are in soils?
water
Why are soils generally less fertile than clayey soils?
Sandy soils are generally less fertile than clay soils because they do not hold water as well as clay soils. Clay soils are usually fertile and hold more nutrients than sandy soils.
What are heavy soil and light soil?
Heavy soils are heavy, high in nutrients and wet like the clay soil. Light soils are light, dry, warm,low in nutrients and often acidic.
What does sandy soils have?
A free draining consistency, and a lack of plant nutrients.
Why do plants grow only in the topsoil?
There are little or no nutrients in other soils.
Sandy soils does what?
A free draining consistency, and a lack of plant nutrients.
