How is nitrogen depleted from soil?
Nitrogen can be depleted from soil through plant uptake, leaching, and runoff. Plant roots absorb nitrogen from the soil to support growth, which can lead to a decrease in soil nitrogen levels over time. Additionally, excess water can cause nitrogen to leach out of the soil and into groundwater, or runoff can transport nitrogen into bodies of water, further depleting soil nitrogen.
What is called soil that is rich in the substances?
Fertile soil.
What is an example of adding nitrogen to soil?
An example of adding nitrogen to soil is by incorporating organic matter such as compost or manure. These materials contain nitrogen-rich compounds that can be broken down by soil organisms to release nitrogen for plant uptake. Another method is using nitrogen-based fertilizers, which directly supply nitrogen to the soil for plants to use.
How can someone increase the nitrogen in the soil?
To increase nitrogen in the soil, you can use nitrogen-rich fertilizers like compost, manure, or nitrogen-based commercial fertilizers. Planting nitrogen-fixing cover crops like legumes can also help increase nitrogen levels naturally in the soil. Finally, rotating crops and avoiding over-tilling can help maintain and improve soil nitrogen levels.
How can there be a shortage of nitrogen in some soil?
Nitrogen in soil can become limited if there is an imbalance in the nitrogen cycle, where plants remove more nitrogen than is being replenished through processes like nitrogen fixation. Factors such as over-fertilization, leaching, erosion, and poor crop rotation can also contribute to nitrogen depletion in soil.
Which crop makes soil fertile?
alfalfa
What is found in soil that makes it fertile?
Organic matter.
When can you say that a soil is fertile?
A soil is considered fertile when it has a balanced pH level, good soil structure, high organic matter content, and essential nutrients for plant growth. Additionally, fertile soil should support healthy root development and have good water retention and drainage capabilities.
What makes the soil in Indonesia good for farming?
The soil is good for farming because it is fertile
What makes soil fertile in middle America?
ash and lava
Why are nitrogen-fixing bacteria contributions to the nitrogen cycle important?
The air is about 80% nitrogen- but cannot be used by plants for food. Nitrogen fixing bacteria transform nitrogen in the air to nitrogen in the soil that plants CAN use- resulting in greatly improved plant growth, and more fertile soil.
Why are nitrogen bacteria contributes to the nitrogen cycle so important?

What sediment makes soil fertile?
Organic matter, such as decomposed plant material and animal waste, helps make soil fertile by providing nutrients for plants to grow. Minerals like potassium, phosphorus, and nitrogen also contribute to soil fertility by supporting plant growth and development. The presence of these components in varying levels can determine the fertility of soil for agriculture and plant growth.

Can you lose the use of soil by soil erosion?
yes because as we mine, the top soil is washed away and this makes the soil in-fertile.
Does fertile soil lack nutrients?
No, fertile soil is rich in nutrients that are essential for plant growth. Soil fertility depends on the presence of key elements like nitrogen, phosphorus, and potassium, as well as other micronutrients. Soils that lack these nutrients are considered infertile.
Do the coastal plains have fertile soil?
Yes, coastal plains typically have fertile soil due to the accumulation of sediment and nutrients carried by rivers and streams. This fertile soil makes coastal plains ideal for agriculture and can support a variety of crops.
