What is the layer of plant remains at the surface of the soil is called?
The layer of plant remains at the surface of the soil is called litter. True. In contour plowing, farmers conserve soil fertility by leaving dead stalks and weeds in the ground.
How can plants can act as agents of both mechanical and chemical weathering?
Plants can cause mechanical and chemical weathering. When plants cause mechanical weathering, their roots grow into rocks and crack them.It can also happen in streets or sidewalks. When plants cause chemical weathering, there roots release acid or other chemicals, onto rocks, which then forms cracks, and breaks apart.
Which of the following is used of soil conservation?
Answer: Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility. When plants die, they decay and become part of the soil.
What do you know about soil conservation?
Soil conservation is the prevention of loss of the top most layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination. Farmers have practiced soil conservation for millennia.
How can plants play a role in the process of weathering?
Plants and animals can be agents of mechanical weathering. The seed of a tree may sprout in soil that has collected in a cracked rock. As the roots grow, they widen the cracks, eventually breaking the rock into pieces. Over time, trees can break apart even large rocks.
How do plants promote mechanical and chemical weathering but inhibit erosion?
SolutionStep 1 of 1:Plants promote both mechanical and chemical weathering of rocks, but it inhibits erosion of thesoil thanks to the roots.1.As roots of the plant grows deep, it crushes the rocks causing a mechanical weathering process. Thusinhibiting erosion of the soil.
What is soil conservation explain the methods of soil conservation?
Soil conservation is the preventing of soil loss from erosion or reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination. Slash-and-burn and other unstainable methods. Methods of Soil Conservation:- 1-Terrace farming. 2- Buffer strip.
Why is conservation of soil important suggest three ways of soil conservation?
It helps in maintaining the food security of the world. (i) By encouraging terrace farming and contour ploughing. (ii) By promoting afforestation. (iii) By controlling overgrazing by animals.
How does the country conserve and protect the soil?
Crop rotation is a process that works to conserve soil. It is accomplished by planting and growing a series of different crops in the same soil. This process prevents overgrowth of pathogens and a lack of fertility in the soil, overall.
Why is conservation of soil important?
Soil conservation is proven to increase the quality and quantity of crop yields over the long term because it keeps topsoil in its place and preserves the long term productivity of the soil. To grow enough food not only for ourselves; but also for people in third would countries where there are food shortages.
How does vegetation in the soil affect the rate of erosion?
It occurs when the soil is saturated or unable to absorb more water. Plants also help absorb some of the water in the soil. These effects make it harder for water to wash the soil away. Plants also help reduce erosion in other ways, such as breaking the wind that might blow dry topsoil away.
How do plants break down rocks and turn into soil as years go by?
Under the action of heat, cold, rain, wind, and other atmospheric factors, the rock breaks down physically into small fragments that become the parent material of the soil. In turn, plants add organic material in the form of roots and leaves to the disintegrating rock environment.
What is the importance of fire and grazing in the Prairie?
Fire and Grazing in the Prairie. Grazing animals play an important role in maintaining the ecosystem by stimulating plants to grow. This triggers biological activity and nutrient exchanges. Bison, deer, and cattle compact the soil with their hooves and open new areas for seeds and the generation of plants to take root.
Why is the Prairie important to the United States?
The prairie has long been known for its incredible fertility. Settlers eagerly plowed the soils to plant crops of corn, wheat, sorghum, and vegetables. Today it is proudly stated that one American farmer feeds 129 people. This is testimony to the rich prairie soils.
What is the role of fire in the tallgrass prairie?
The role of fire is prevalent in almost every ecosystem. However, few involve fire as frequently as does prairie. Tallgrass prairie can accumulate an enormous amount of biomass (dead plants) in one year. The leaves die in the fall and the roots go dormant during the cold winter months.
What are two factors that affect prairie maintenance?
Two factors of prairie maintenance are fire and grazing. Grazing animals play an important role in maintaining the ecosystem by stimulating plants to grow. This triggers biological activity and nutrient exchanges.
