Thorstein’s Fields Pack
This mod contains 34 different fields: from very small (25m x 100m; 50m x 50m) up to massive ones (1000m x 1000m; 500m x 2000m) to make your rural areas more realistic.
Big fields (over 10ha) have industrial connections to better connectivity.
Note that biggest fields will need workers – tractors and harvesters will be too slow for so big area
