Land renting and population increases?

[SergeantEpson]

Is there any way to mod and increase the max (useful) land you can own?

After about 150 acres the surplus thing kicks in and there isn't really a point in creating nay more land. How do I increase the cap?

Go to another town. I noticed that the amount of cultivated land grows slowly(probably with prosperity)
