Farmville Crop Whisperer

It seems that everyone is playing Farmville and I am the only one left not playing it. I have a farm in Farmville but I don't have time to till my virtual farm, it is my four-year-old son who cares for my virtual farm. My son knows a lot about farmville and now he told me about this new feature called Farmville Crop Whisperer. What is it? To be honest, I really don't know, but based on what I have gathered from my son, this new feature allows players to randomly select users gift, and recognize 5 bags of fertilizer each day. What is its implication on the game? Again, I really do not know, I'll ask my little boy about it.
