Soil

Soil, by definition, is a earthly compound comprised of biotic (living) and abiotic (non-living) matter that is formed in several layers over millions of years. It is the very component of the Earth that plants need to root themselves and grow in in order to feed all animal life. There are many different types of soil across the globe for each continent and biome, and each type has its characteristics that depict what plants can grow where, when, and how. Questions and answers about soil can be asked and answered here.

What does a farmer practices when he prepares new farmland to replace fields in which soil has been exhausted?

The farmer practices crop rotation, where different crops are planted in succession to replenish nutrients in the soil. This helps prevent soil exhaustion and maintains soil fertility. Additionally, the farmer may add organic matter such as compost or manure to improve soil structure and nutrient content.

Why is loam more fertile than silt?

Loam soil is more fertile than silt because it has a balanced mixture of sand, silt, and clay particles, which provides good drainage, moisture retention, and nutrient availability for plant growth. Silt soil has smaller particles that compact easily, leading to poor drainage and limited nutrient availability, reducing its fertility compared to loam.

Is Waste is deposited into landfills and in thin layers which are then compacted and covered with soil?

Yes, waste is typically deposited into landfills in thin layers, which are then compacted to reduce the volume and covered with soil to minimize odor, pests, and the risk of contamination. This helps to manage and contain the waste effectively within the landfill site.

Which soil type gets waterlogged and floods after lots on rain?

Clay soils are more prone to waterlogging and flooding after heavy rain due to their small particle size and poor drainage characteristics. The fine particles in clay soil can compact together, making it difficult for water to percolate through the soil, leading to waterlogging and flooding.

Does compacted soil absorb less water when wet or dry?

Compacted soil absorbs less water when wet, as the pores in the soil become filled with water and limit additional water flow into the soil. When the soil is dry, the pores are more open, allowing for better water absorption.

What are the abiotic factors which affect soil formation?

Freeze / thaw action of ice & water in cracks causes breakdown of larger rock surfaces. Same with wind blown & water eroding particles. Acids in rain water (mainly carbolic - from CO2 but also others) dissolve carbonate rock so making more cracks/erosion and adding carbonates to soil.

What is best soil to grow beans in?

Beans grow best in well-draining soil with a pH between 6.0-7.0. A loamy soil rich in organic matter is ideal for beans as it provides good aeration and nutrient availability. Adding compost or aged manure to the soil can also help improve soil fertility for bean plants.

Why is soil permeability important?

Soil permeability is important to plants that lives on land. The space between soil particles are called pore spaces. Water and air filled these spaces. The size of pore spaces and the way in which the pore spaces are connected affect permeability. Because, permeability is the rate which water can pass through a porous material. Soils through which water passes quickly have a high permeability.

What happens to the seed in the soil?

When a seed is planted in soil, it germinates by absorbing water and nutrients from the soil. The seed then undergoes cell division and growth, sending up shoots and roots to establish itself as a new plant. Over time, the seed coat may decompose as the plant grows larger.

How soil as a natural body differs from soil a material used in construction?

Soil as a natural body is formed through natural geological processes over time and consists of minerals, organic matter, air, and water. In construction, soil is typically excavated and manipulated to build structures like foundations or road embankments. In construction, soil properties may be modified through compaction or stabilization methods to meet specific engineering requirements.

Which condition most likely exists when precipitation is greater than evapotranspiration and soil water storage is at its maximum?

The condition most likely to exist in this scenario is that the soil is saturated or at field capacity. This means that the soil is holding as much water as it can and any additional precipitation will result in runoff.

What are the different conservation measures?

Conservation measures include protecting habitats from destruction, enforcing regulations on hunting and fishing, creating protected areas, promoting sustainable resource management practices, and raising awareness about conservation issues. These measures aim to safeguard biodiversity, ensure the survival of threatened species, and maintain healthy ecosystems for future generations.

What must happen first for soil to form'?

The weathering of rocks must first occur, breaking down rocks into smaller particles. These particles then mix with organic matter and other materials, undergoing physical, chemical, and biological processes to form soil.

What is rich soil made up of sand and mud deposited by moving water?

Rich soil is typically composed of a mixture of sand, silt, clay, minerals, organic matter, and nutrients. These components contribute to the soil's fertility and ability to support plant growth. A balance of these elements is important for healthy soil.

Where does soil get most of its nutrient?

Possibly from decomposed matter?

Either that or it was full of nutrients to begin with.

Which type of soil dries out quickly after a rain shower?

Sandy soil tends to dry out quickly after a rain shower due to its large particle size and poor water retention capacity. The porous nature of sandy soil allows water to drain away more rapidly compared to other soil types like clay or loam.

How does the struction of soil affect its fertility?

Soil structure refers to the arrangement of soil particles and pore spaces. A well-structured soil with good aggregation allows for better root penetration, air exchange, and water infiltration, promoting overall soil fertility. Poorly structured soil with compacted layers can hinder root growth, reduce water drainage, and limit nutrient uptake, decreasing fertility.

What is the particle size of loam?

Loam soil typically has a particle size that falls between sand and clay, making it a mixture of different particle sizes. The particle size ranges from 0.002 to 0.02 mm, allowing for good drainage and moisture retention in the soil.

Why subsoil facctors can affect new and other construction project?

Subsoil factors, such as soil composition and water table level, can impact the stability and foundation of a new construction project. Different soil types have varying load-bearing capacities, which can affect the structural integrity of the building. Additionally, factors like soil settlement or expansive soils can cause issues with the long-term durability of the construction. Understanding and addressing subsoil factors is crucial to ensuring the safety and longevity of the building.

Why is the soil important to life on earth pictures?

Soil is important to life on Earth because it is the foundation for plant growth, providing nutrients, water, and support for roots. Soil also helps regulate the Earth's climate by storing carbon, filtering water, and supporting various ecosystems. Additionally, soil is crucial for food production, as it is where the majority of our food crops are grown.

When there not enough plants to hold topsoil in place water and carry the topsoil away leaving the subsoil exposed?

This is called soil erosion, where the top layer of soil is washed away by water or wind. It can lead to reduced soil fertility, loss of nutrients, and decreased ability of the land to support plant growth. Implementing erosion control measures like planting cover crops or building terraces can help prevent soil erosion and maintain soil health.

Where is clay soil normally found?

Clay soil is typically found in areas with a high content of fine particles, such as silicate minerals and decomposed rock material. It can be found in regions with a history of volcanic activity or in areas where glaciers have deposited sediment. Clay soil is often found in low-lying areas that have poor drainage.

What is soil called that is made up of equal parts of clay sand and silt?

Your answer is Loam soil or terreau and it's the healthyest for plants.

What happens when mongo seed is planted in sandy soil?

When mongo seed is planted in sandy soil, it can easily establish root systems due to the loose texture of the soil. However, sandy soil tends to drain quickly and may not retain enough moisture for optimal growth. To address this, it is important to provide frequent irrigation and incorporate organic matter into the sandy soil to improve water retention and nutrient availability for the mongo plant.

How does soil temperature influence plants growth?

Soil temperature affects plant growth by influencing metabolic processes and nutrient uptake. Warmer temperatures can enhance plant growth by increasing enzyme activity, nutrient availability, and root growth. However, extreme temperatures, whether too hot or too cold, can stress plants and affect their ability to photosynthesize and absorb water. Balancing soil temperature is crucial for optimizing plant growth and overall health.
