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)

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

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
