From the surface down these layers are known as Soil Horizons. The top one is called leaf-litter.
Soil conductivity is a measure of a soil's ability to conduct an electrical current. It is influenced by factors such as soil moisture content, soil texture, and the presence of salts and minerals. Higher soil conductivity levels can indicate higher levels of salinity, which can impact plant growth.

Fertilizers are added to soil to increase nutrient levels. Common fertilizer types include nitrogen, phosphorus, and potassium, which are important for plant growth. Organic matter such as compost can also be added to the soil to improve nutrient levels.
Nitrate soil refers to soil that contains high levels of nitrate, a form of nitrogen that plants can take up and use for growth. While nitrate is essential for plant growth, excessive levels can lead to environmental issues like water pollution. Agricultural practices and fertilizer use can greatly affect nitrate levels in soil.
Measurements of soil acidity are called pH levels. pH levels range from 0 to 14, with levels below 7 indicating acidity, levels above 7 indicating alkalinity, and a pH level of 7 being neutral.
To increase iron levels in soil, you can add iron-rich fertilizers or amendments such as iron sulfate or iron chelates. Additionally, maintaining proper soil pH levels and improving soil drainage can help enhance iron availability to plants.

To effectively lower calcium levels in soil, you can use soil amendments like sulfur or gypsum to help reduce the pH level of the soil. This can help decrease the availability of calcium to plants. Additionally, you can also consider using plants that are known to accumulate calcium, which can help in reducing the overall calcium levels in the soil over time.
The color of the soil usually indicates the type of minerals and levels of nutrient in the soil.
Measurements of soil acidity are called pH levels. pH levels range from 0 to 14, with levels below 7 indicating acidity, levels above 7 indicating alkalinity, and a pH level of 7 being neutral.
True.
Temperature can affect pH levels in soil by influencing microbial activity and chemical reactions. Warmer temperatures can accelerate the rate of chemical reactions, potentially leading to changes in pH levels. On the other hand, colder temperatures may slow down microbial activity, which can also impact the pH of the soil.
Topsoil is darker than other levels of soil because it is rich in organic matter such as decomposed plant and animal material. This organic matter adds nutrients to the soil and contributes to its dark color.
Scientific investigations on Sudbury's soil revealed the decrease in soil pH was correlated with increased copper and nickel levels.
