Why is top soil fertile?
Topsoil is fertile because it contains organic matter, nutrients, and microorganisms that support plant growth. Organic matter provides nutrients and improves soil structure, while microorganisms help break down organic matter into forms that plants can absorb. The combination of these factors makes topsoil an ideal environment for plant roots to thrive.
What is the texture of forest soil?
Forest soil texture can vary depending on factors like the type of trees present, climate, and organic matter content. Generally, forest soil is a mix of sand, silt, and clay particles, with a high content of organic matter. This organic matter contributes to its dark color and crumbly texture.
When it rains a soil holds water well and becomes moist and sticky what does this contain?
When rainwater is absorbed by soil, it mixes with organic matter, minerals, and microorganisms present in the soil. This creates a moist and sticky environment that promotes plant growth by providing necessary nutrients and moisture for roots to absorb.
What is the best soil for farming?
The best soil for farming is loam soil, which is a combination of sand, silt, and clay. This soil type has good drainage, holds moisture well, and provides a good balance of nutrients for plant growth. Farmers often amend their soil with organic matter to improve its structure and fertility.
A soil with many nutrients that holds water poorly?
Sandy soil is typically nutrient-poor but drains well, whereas clay soil is nutrient-rich but often retains water. A soil that holds water poorly but has many nutrients may be loamy soil, which is a mix of sand, silt, and clay and offers good drainage while being nutrient-rich. Organic matter can also improve water retention in nutrient-rich soils.

Does non-organic or organic soil hold more water?
Organic soil holds more water than non-organic soil. An article written by Lara Bryant for the expert blog component of the Natural Resources Defense Council website Wednesday, May 27, 2015, provides the math for the relationship between organic matter and water holding capacity increases. It states that a one percent increase in organic matter yields an increase by 21,668 gallons (82,022.30 liters).

Organic matter can also improve water retention in nutrient-rich soils.
Which type of soil holds the least amount of water?
Sandy soil typically holds the least amount of water due to its large particles and low organic matter content, which allows water to drain through quickly.
What layer of soil holds water?
The B horizon, also known as the subsoil, typically holds more water than the A horizon. This layer is located beneath the topsoil and above the C horizon, and it contains minerals, organic matter, and nutrients that help retain water for plant roots.
Why do people use soil instead of sand?
Soil contains organic matter and nutrients necessary for plant growth, while sand does not have these properties. Additionally, soil has better water retention and aeration capabilities compared to sand, which helps in supporting plant growth. Overall, soil provides a more conducive environment for plants to thrive than sand.
How does manure help crops grow?
As the manure breaks down, it releases crucial nitrogen into the soil. It also can alter the pH of the soil, bringing it to the correct level needed for the crop. That is why you often see cattle in a field for a few months of the year, and later, a crop in that same field.
What are some factors that can affect Dissolved Oxygen?
Temperature: Lower temperatures generally result in higher dissolved oxygen levels. Salinity: Freshwater holds more oxygen than saltwater. Turbulence: Mixing and aeration from water movement can increase dissolved oxygen levels. Organic matter: Decomposition of organic matter by bacteria can deplete oxygen levels.
How do roots help make soil?
When water gets into the soil, it pours into pores. Pores are spaces in the soil that come in different sizes. The bigger the pore, the more water it holds.
