NO ,it is not true...fertile soil contain nutrients
True. The Great Plains region in the United States is known for its fertile soil, which is conducive for agriculture. This soil, formed by the deposition of sediment from glaciers and rivers over time, is essential for growing crops such as corn, wheat, and soybeans.
Yes, crushed eggshells can be beneficial for the soil as they provide calcium, which helps improve soil structure and can enhance plant growth. The eggshells can also deter some pests and add nutrients to the soil as they break down.
No, unweathered rock that underlies soil is typically referred to as bedrock, not subsoil. Subsoil is the layer of soil beneath the topsoil that is rich in minerals and nutrients.
The true density of soil is important for calculating porosity and void ratio, which affect the soil's ability to hold water and nutrients. It is also used to determine soil texture and compaction levels, which can impact plant growth and stability for construction projects. Additionally, true density can provide insights into soil composition and help assess soil quality for various applications.
Yes, soil in dry areas tends to have lower moisture content, which can slow down biological activity and nutrient cycling. This can lead to slower decomposition rates and overall reduced soil fertility compared to more moist environments.

In true organic farming, the soil is built up with organic matter, which means nutrients in the soil are replenished. In non-organic farming, fertilizers are used to replenish certain nutrients only, while other nutrients may be depleted. In that sense, soil (nutrients in the soil) last longer in organic farming.
true!!!!
Yes, when nutrients are leached from the soil, they are carried away by water moving through the soil. This process can occur due to rainfall or excessive irrigation, leading to a loss of essential nutrients for plant growth.
Yes, slash and burn agriculture can temporarily improve soil fertility by releasing nutrients from burned vegetation. However, this method is not sustainable in the long term and can lead to soil degradation, erosion, and loss of biodiversity. Modern sustainable farming practices focus on preserving soil health for continued productivity.

The Nile River had incredibly fertile soil.
