Introducing the latest feature in Farmville -- Crop Fertilizer. Question is where do we get this fertilizer? You can't buy the fertilizer cause it's for free! Randomly selected users will receive five bags of fertilizers per neighbor, per day so everybody has the chance!
Once you've received a fertilizer, you can use it on the crops of your neighbors' farms. Fertilized crops will appear bigger than normal crops and they will sparkle.
Fertilizer bags will be awarded when you complete a friend mission (pulling weeds, chasing crows, etc.) and removed when you visit another neighbors farm. Rewards are experience points (XP).
