Effects on Crops1) Faster plant growth2) Allows healthier plants that are more resistant
to pests and disease

Effects on Crops1) Faster plant growth2) Allows healthier plants that are more resistant
to pests and disease3) Increased nutrients allows more plants to be
grown in a smaller area
Results: Increased crop yields 30%-50% more plants produced
