the dust bowl was caused partially by the great depression, due to the depression, farmers were trying to make maximum profit, so they cut down trees to get more land, planted too much, and let cattle graze too much, and that took out all the roots holding the soil together, causing the soil to loosen into dust and …

What causes soil damage and loss quizlet?

What cause soil damage and loss? When it lose fertility by water and wind erosion. How do farmers help conserve soil? By soil conservation, crop rotation and contour plowing.

What is the main mechanical method used by farmers to control soil erosion?

Crop Rotation: Rotating in high-residue crops — such as corn, hay, and small grain — can reduce erosion as the layer of residue protects topsoil from being carried away by wind and water. Conservation Tillage: Conventional tillage produces a smooth surface that leaves soil vulnerable to erosion.

What are the 2 types of soil?

Soil Types

  • Sandy soil. Sandy Soil is light, warm, dry and tend to be acidic and low in nutrients.
  • Clay Soil. Clay Soil is a heavy soil type that benefits from high nutrients.
  • Silt Soil. Silt Soil is a light and moisture retentive soil type with a high fertility rating.
  • Peat Soil.
  • Chalk Soil.
  • Loam Soil.

What is a Class 1 soil?

Class I (1) soils have slight limitations that restrict their use. Class II (2) soils have moderate limitations that reduce the choice of plants or require moderate conservation practices. Class III (3) soils have severe limitations that reduce the choice of plants or require special conservation practices, or both.

What are 2 benefits of healthy soil?

Healthy soil helps bind particles together, improves soil structure, retains water, and improves the soil fertility resulting in higher yields for farmers.

What are the disadvantages of using soil?

  • Major soil erosion. High soil moisture loss. Timeliness considerations.
  • Little erosion control. High soil moisture loss.
  • Little erosion control with more operations. High soil moisture loss.
  • No incorporation. Increased dependence on herbicides.
  • No incorporation. Must be annual row crops.

How do we use soil in everyday life?

Humans use soil as a holding facility for solid waste, filter for wastewater, and foundation for our cities and towns. Finally, soil is the basis of our nation’s agroecosystems which provide us with feed, fiber, food and fuel.

Do we need soil?

Soil plays many important roles in nature and for our wellbeing. Without soil, most plants wouldn’t be able to grow in nature. Soil provides the physical anchor that plants live in, but it is also where plants obtain important things that they need, such as nutrients and water.

Which soil absorbs most water?

Loam Soil is best. A combination of sand, silt, and clay particles, this soil absorbs water readily and is able to store it for use by plants. Loam absorbs water at a rate between 1/4 and 2 inches per hour. Sandy Soil, because it has very large spaces, absorbs water at a rate of more than 2 inches per hour.

What can I add to potting soil for drainage?

Sphagnum peat moss is mixed into sandy soils to help hold moisture and into clay soils to loosen the soil and improve drainage. Sphagnum moss is also used as a liner for hanging baskets of plants. Perlite helps aerate the soil, hold water and keep soil from packing down.

What do you put in the bottom of a planter for drainage?

Reuse your Styrofoam packing peanuts as filler for large pots. Packing peanuts create drainage and are built to last. At the bottom of a container, they will prevent your plants from drowning in too much water.

How do you fix waterlogged soil?

Strategies for Dealing with Water Logged Soils

  1. Plant Cover Crops. Cover crops are an excellent way to use excess water.
  2. Go No-Till. A more long term strategy, going no -till improves soil structure to help with drainage.
  3. Add Organic Material.
  4. Subsoil.
  5. Build Raised Beds.
  6. A Note About Sand.
