How did the earths atmosphere change composition to become todays nitrogen and oxygen atmosphere?
your question is... How did the Earth`s atmosphere change composotion to became today`s nitrogen and oxygen atmosphere? Answer: it happend with the help of solar untraviolet (uv) radiation,the very thing what we worry about now for its cancer-causing ability
Why did World War 2 lead to the permanent end to isolationism?
The world learned it must work together to maintain peace, restore devastated countries, help those in need, restore global trade and they formed the United Nations to promote global communication and prevent future world wars. It discovered that isolationism was too idealistic. The Cold War forced the situtation anyway.
Does an earthworm have jaws?
Earthworms do not have jaws. They suck their nutrition through their mouth by the help on the pharynx and this food is churned in the gizzard after passing trough the esophagus and or being stored in the crop.
How do earthworms improve garden health?
The opening up of passageways through the soil and the leaving of nutrient rich organic matter are two ways in which earthworms improve garden health. The passages that they open in their movements through soil encourage the presence of air and water pore spaces. Pore spaces encourage appropriate levels of air and moisture below ground. They thereby discourage compaction and erosion.The matter that earthworms leave in soil comes in the form of droppings. These droppings are high in such important nutrients as nitrogen. Plants only can take nitrogen in soluble form. Nitrogen that otherwise is unavailable to plants becomes available once it passes through and out of earthworm.
What is the difference between a planet's rotation and a planet's revolution?
Earth rotates on its axis and it revolves around the sun. Both things conserve earth's angular momentum. Each rotation is a day, and each solar revolution is a year. The days and years both help us mark the passage of time. Other than that, there are not too many similarities.
What is crop rotation and how do peanuts help it?
Crop rotation is planting different crops in different years. This prevents pulling out all the nutrients by a specific type of crop. Peanuts and other legumes help return nitrogen to the soil. Rotation improves the crop yields.
Which crop is grown between two cereal crops to restore the fertility of soil?
A legume crop is typically grown to help restore the nitrogen levels.
What can you do to reduce the amount of nitrogen in the soil?
To reduce the amount of nitrogen in the soil, you can practice crop rotation, plant cover crops that absorb nitrogen, decrease the use of nitrogen-based fertilizers, and avoid over-fertilizing. Implementing these practices will help restore a healthy nitrogen balance in the soil.
Is crop rotation helpful?
Yes, extremely. When plants are planted that drain the soil of nutrients, rotating the field with a plant such as peas or peanuts, can help restore the soil.
What is the system of crop rotation used in the later middle Ages and how it increased the amount of food being grown?
In the Middle Ages, one important improvement was the three field system of crop rotation, in which a field would be planted with one crop in one year, a different crop the next year, and no crop in the third year so it could lie fallow and recover. Prior to this, a different system was used, but the three field system increased the amount of available land for farming by a third. This system of crop rotation meant that more people could be fed by each farmer, and this was one of the important factors in the growth of towns and cities.
How can crop rotation help maintain the fertility of soil?
Crop rotation can help maintain soil fertility by reducing the depletion of specific nutrients in the soil. Different crops have varying nutrient requirements, so rotating crops helps prevent the build-up of pests and diseases that can impact soil health. Additionally, certain crops can fix nitrogen in the soil, benefiting subsequent crops in the rotation.
What are the plants that help restore nitrogen to the soil?
the pea family
What is the name of the plants that help restore nitrogen to the soil?
Tulip
How can a farmer protect the nitrogen content or soil?
Farmers can protect the nitrogen content in soil by practicing crop rotation, using cover crops, and reducing the amount of synthetic fertilizers applied. These practices help to maintain a healthy nitrogen balance in the soil, which is essential for plant growth and soil fertility.
What is the name of crop that is grown alternately?
The growing of different kinds of crops on a piece of land in a preplanned succession is known as crop rotation. In the rotation of crops, leguminous crops like pulses, beans, peas, groundnut and Bengal gram are sown in-between the seasons of cereal crops like wheat, maize and pearl millet. The leguminous plants are grown alternately with non-leguminous plants to restore the fertility of the soil. When the cereal crops like rice, wheat, maize are grown in the soil, it uses up a lot of nitrogenous salts from the soil. If another crop of cereal is grown in the same soil, the soil becomes nitrogen deficient. So by rotation a leguminous crop is grown. There plants have the ability to fix atmospheric nitrogen to form nitrogen compounds through the help of certain bacteria present in their root. These nitrogen compounds go into the soil and make it more fertile. After the leguminous plants utilize some of the nitrogen compounds, the rest of it is left in the soil to enrich it. Thus, planting a leguminous plant will result in nitrogen rich soil and when a cereal is grown in this soil there is increase in food grain production.
Why is crop rotation significance?
Crop rotation is significant because it helps to maintain soil fertility by preventing nutrient depletion. It can also help control pests and diseases that are specific to certain crops. Additionally, crop rotation can improve crop yield and overall farm productivity.
Why do farmers plow a crop of legumes into the ground rather than harvest it?
They use it to restore soil nitrogen, because it improves the soil structure for better harvests.
