you say---"-Fertilization Process:
You need 50 manure units to fertilize a farm. To fertilize a farm, click on the Manure Spreader tool and select 'Fertilize Farm'.
Once a farm is fertilized it will remain fertilized for the next 3 days."
so in other words it does NOT FERTILIZE 4 DAY CROPS??? IT ONLY FERTILIZES THE FARM FOR 3 DAYS??? why is that????
