Hello, students! Welcome back to Primary 5 Pre Vocational Studies, Agricultural Science. In our previous lesson, we learned about how to grow crops, specifically thinning and supplying. Today, we’re going to learn about the important role of fertilizer and manure in helping our crops grow strong and healthy.
Objectives
By the end of this lesson, you should be able to:
- Explain the steps involved in applying fertilizer and manure to crops.
- Demonstrate appreciation for the importance of proper fertilizer and manure application.
- Work in groups to discuss and practice the application of fertilizer and manure.
How To Grow Crops; Application Of Fertilizer And Manure
What are Fertilizer and Manure?
Fertilizers and manure are like special food for our plants. They provide essential nutrients that help crops grow strong and healthy.
Fertilizers are chemical or natural substances added to the soil to increase its fertility. Think of them as vitamins for the soil! Manure is organic material, often made from animal waste, that enriches the soil. It’s like giving the soil a healthy snack.
Applying Fertilizer
There are a few important steps to follow when applying fertilizer:
- Determine the right type: Just like we need different foods for different needs, plants need different types of fertilizers. Choose the fertilizer that is best for your specific crop.
- Measure the correct amount: Too much fertilizer can harm the plants, so it’s important to measure the right amount. Follow the instructions on the fertilizer package.
- Spread evenly: Apply the fertilizer evenly around the base of the plant, making sure it doesn’t touch the stems.
- Water the soil: After applying fertilizer, water the plants well. This helps the fertilizer penetrate the soil and reach the roots.
Applying Manure
Manure is a great natural way to improve soil health. Here’s how to apply it:
- Select the manure: Use well-rotted manure, as it’s less likely to burn the plants.
- Prepare the soil: Loosen the soil around the crops before applying the manure. This helps the manure mix in better.
- Apply near the roots: Spread the manure around the base of the plants, but avoid direct contact with the stems.
- Mix and water: Lightly mix the manure with the topsoil and water it well.
Lesson Evaluation
To see how well you’ve learned about fertilizer and manure, let’s answer these questions:
- What is the difference between fertilizer and manure?
- Describe the steps involved in applying fertilizer to crops.
- Why is it important to water the soil after applying fertilizer or manure?
- What are some benefits of using manure for crops?
- Imagine you have a small garden. How would you apply fertilizer and manure to your plants?
Conclusions
Great job today, everyone! Remember, using fertilizer and manure correctly is crucial for growing healthy and productive crops. Don’t forget to ask questions if you have any, and keep exploring the world of agriculture! See you in the next lesson!
