visit to a sod farm

This monday,we visited a sod farm-Mountain Sod Farms.it covers about 550 acres filed.This company has established their business for 49 years.   The owner recepeted us,when we arrived ,he was harvesting sod.

look at his mower,really brilliant ,this is an effective machine supported by computer.it can cut the sod precisely for a certain length and width.and then delivers it by a conveyor.


Then it rolls the sod through this special track.

After that ,it puts those rolls inside the back container.

when harvest enough rolls ,our driver will stack rolls up like this:
 
To imagine how precise this mower is ,just have a look at the sod track it just got through.


This farm uses pipe irrigation system ,the pipes are set around the field.here they are：

when watering,here will be like this:

The owner told us that the best time to cut sod should be in early morning,because at this time ,moiture will come up to the surface,so it is easier for cut and better for holding moisture in soil which have been rolled out with roots.Normally sod growing season needs two years,the first year to get prepared and sale in second year.
I think,for sod market,it mainly has something to do with sports,like football fields,golf fields.sports customers are the one who need to change their turf regular and to maitain.so for sod farm business,it is better to set nearer to areas where football or golf games are popular.
