To the Learners
Looking Back
This module was designed to help you identify the different ways of
conserving and protecting the soil for future generations.
After going through this module, you are expected to:
- Give different ways of conserving and protecting the soil for future generation
Directions: Choose the letter of the correct answer. Write the chosen letter on a separate sheet of paper.
Identify what method of soil conservation plows along the curves, or contours, of a slope. A. Crop Rotation C. Contour Plowing B. Terrace Farming D. Conservation Tillage
What do you call the method of soil conservation that leaves the previous year’s residue on fields before and after planting the next crop? A. Crop Rotation C. Contour Plowing B. Terrace Farming D. Conservation Tillage
If you are a farmer and you plant different crops on the same field in different years or growing seasons, what method of soil conservation are you practicing? A. Crop Rotation C. Contour Plowing B. Terrace Farming D. Conservation Tillage
Identify what method of soil conservation is shown when rows of trees are planted between fields to “break”, or reduce, the force of winds that can carry off soil. A. Contour Plowing C. Contour Plowing B. Windbreaks D. Terrace Farming
How will you describe terrace farming? A. Rows of trees planted between fields C. Plows along the contours of a slope B. Barren land with seasonal crops D. Flat, step-like areas on hillside
From your previous lessons, you learned that soil is a non-renewable natural resource. The way people use land can affect the levels of nutrients and pollution in soil. There are different activities that humans execute that make the soil lose its quality as well as its quantity.

Expectations
Advantages of Crop Rotation increases soil fertility increases crop yield increases soil nutrients reduces soil erosion limits the concentration of pests and diseases reduces the stress of weeds improves the soil structure reduces pollution diversification and Reduced Cost of Production nutrient uptake regulation
Disadvantages of Crop Rotation involves risk improper implementation can cause much harm obligatory crop diversification requires more knowledge and skills the difference in growing conditions
- Terrace Farming
quora/What-is-terrace-farming-Where-is-it-practiced
Terrace farming uses “steps” called Andenes (Spanish term for platform), which is a step-like terrace that are built on the side of the mountain or hill. On each step, various crops are planted, and when it rains, instead of washing away all of the nutrients in the soil, the nutrients are carried down on the next level. It is one of the oldest types of land and water resource management for large- scale farming.
Advantages of Terrace Farming reduces both the amount and velocity of water moving across the soil surface permits more intensive cropping
Disadvantages of Terrace Farming requires a huge inputs of labor to construct and maintain unmaintained terraces can lead to mudslides rainwater saturation of the ground
- Contour Plowing
wattpad/111312422-ways-to-control-soil-erosion-contour-plowing
It is the practice of plowing along the curves, or contours, of a slope. The rows form slow water run-off during rainstorms to prevent soil erosion and allow the water time to settle into the soil. It helps channel rainwater so that it does not run straight downhill, carrying away the soil with it.
- Windbreaks
iowapublicradio/show/talk-of-iowa/2017-03-24/establishing-and-restoring-windbreaks
Windbreaks are rows of trees planted between fields to “break”, or reduce, the force of winds that can carry off soil. They are designed to enhance crop production, protect people and livestock, and benefit soil and water conservation.
Advantages of Terrace Farming modifies the climate in the areas they shelter reduce soil erosion increase crop yield protects livestock from heat and cold can shield buildings and roads beautifies the landscape and provide travel routes and habitat for wildlife
Disadvantages of Terrace Farming money and time are needed to plant the trees the area in which the windbreak is planted is a lost to production needs maintenance to function properly
Action Plan Making Objective: Evaluate which soil conservation method is suitable to the country’s type of soil. Direction: If you are an environmentalist and you want to protect and save the soil, how are you going to do it? Make an action plan that will show how you are planning to do it. You may choose any one of the soil conservation method to help you with your plan. ACTION PLAN to PROTECT AND CONSERVE THE SOIL Target Area/Place To Do Person Involved Time Duration
Objective: Recognize the similarities and differences of Contour Plowing and Terrace Farming. Direction: Using a Venn Diagram, compare and contrast Contour Plowing and Terrace Farming.

#######
Soil can be protected and conserved. Most soil conservation methods are designed to hold soil in place and keep it fertile. Soil conservation methods: Crop rotation, Terrace Farming, Contour Plowing, Windbreaks, and Contour Tillage. The effects of human activities on soil can be mitigated through sustainable soil management such as increasing soil organic matter content, keeping the soil
Activity 2
Remember
Activity 3
surface vegetated, avoiding excessive tillage, using nutrients wisely, promoting crop rotations, reducing erosion, and preventing soil compaction.
Directions: Supply the missing words to complete the following statements.
What Have I Learned?
