2. What are fertilizers Fertilizer: A substance added to soil to supply one or more plant nutrients needed for the growth of the plants.

3. What are fertilizers Fertilizer: A substance added to soil to supply one or more plant nutrients needed for the growth of the plants. Types of fertilizers: -Organic: made of only living materials -Inorganic: made of nonliving materials such as rock

4. What are fertilizers Fertilizer: A substance added to soil to supply one or more plant nutrients needed for the growth of the plants. Types of fertilizers: -Organic: made of only living materials -Inorganic: made of nonliving materials such as rock -Natural: Coming from nature -Synthetic: Man Made (made in a laboratory or factory)

5. Effects on Crops 1)Faster plant growth 2)Allows healthier plants that are more resistant to pests and disease Results:

6. Effects on Crops 1)Faster plant growth 2)Allows healthier plants that are more resistant to pests and disease 3)Increased nutrients allows more plants to be grown in a smaller area Results: Increased crop yields 30%-50% more plants produced

7. Nutrients needed by plants Nutrients: Macronutrients: Used by plants in large amounts Micronutrients:

8. Nutrients needed by plants Nutrients: Macronutrients: Used by plants in large amounts -Hydrogen, Carbon, Oxygen, Nitrogen, Phosphorous, Potassium, Calcium, Magnesium, Sulfur Micronutrients:

9. Nutrients needed by plants Nutrients: Macronutrients: Used by plants in large amounts -Hydrogen, Hydrogen, Oxygen, Nitrogen, Phosphorous, Potassium, Calcium, Magnesium, Sulfur Micronutrients: Used by plants in minute amounts. -Boron, Chlorine, Iron, Magnesium, Molybdenum, Zinc, Nickel

10. Forms of Synthetic Fertilizer Quick Release -Granular (like gravel) -Powdered -Liquid Slow release: -tabs and spikes
