What is a soluble mineral salt occurring in arid soils?
Gypsum is a common soluble mineral salt found in arid soils. It plays a role in soil formation and can impact soil fertility and structure. Excessive gypsum accumulation can lead to soil salinity issues.
Why are sand silt and clay considered mineral soil?
Sand, silt, and clay are considered mineral soil because they are primarily composed of mineral particles derived from rock weathering. These particles are rich in essential nutrients needed by plants for growth and are an important component of most soils. Additionally, mineral soils have distinct physical properties and characteristics that differentiate them from organic soils.
Minerals move downward through soils in a process called what?
Minerals move downward through soils in a process called leaching. This occurs when water carries the minerals down through the soil layers, eventually reaching the groundwater or being deposited in lower layers of soil.
Which type of soil develops due to high temperature and rainfall?
Tropical rainforest soils, such as laterite soils, can develop in areas with high temperatures and rainfall. These soils are typically highly weathered and leached, resulting in lower fertility and mineral content.
What term refers to removal of soluble inorganic components from soils?
Leaching is the term that refers to the removal of soluble inorganic components from soils by water moving through the soil profile. This process can lead to a loss of nutrients and minerals, affecting soil fertility. Agricultural practices and excessive rainfall can increase leaching rates.

How does a plant get a supply of mineral salt?
Plants absorb mineral salts from soils and waters.

What are soluble salts and what is the damage caused by them?
Soluble salts are the halogenides of alkali metals, nitrates, sodium carbonate, sodium sulfate, etc. Soluble salts can contribute to the pollution of water and soils in the case of an accident.
How does a plant get a supply of mineral salts?
Plants extract the needed salts from soils.

Why are volcanic soils are some of the most fertile soils on earth?
volcanic rocks are made of mineral that contain a wide variety of elements that are important to plant growth.
Is soil soluble or insoluble?
Soil is a heterogeneous mixture of both soluble and insoluble components. Soluble components in soil can dissolve in water, while insoluble components do not dissolve. The solubility of different substances in soil depends on their chemical composition and properties.

Tropical rainforest soils, such as laterite soils, can develop in areas with high temperatures and rainfall. These soils are typically highly weathered and leached, resulting in lower fertility and mineral content.

What are the soil types in freshwater biomes?
The soil types in freshwater biomes are generally categorized as mineral soils, organic soils, and sand-based soils. Mineral soils are composed of clay, silt, and sand particles with various levels of organic matter. Organic soils are rich in decomposed plant and animal matter, while sand-based soils have larger particles and lower fertility levels. The specific soil type in a freshwater biome can vary based on factors such as water flow, nutrient availability, and vegetation cover.
How do you fertilise sandy soil?
You should either fertilize sandy soils with slow release fertilizers, like organic fertilizers, or add nutrients slowly with irrigation water. Sandy soils have less ability to hold nutrients than other soils, and soluble nutrients can leach out very quickly.
