It is from our national anthem.

And it means: The Czech land is my home.

@LukeAlmighty Oh, I see. Linebreaks confused me and I didn't connect Česk to mean Czech

Земля чека - дом мой
Zemlya cheka - dom moy

@applejack
BTW, our anthem has 2 parts, but we sing only the first one.. because the 2nd is:

Kde domov můj,
kde domov můj.
Znáte v kraji bohumilém
duše outlé v těle čilém,
mysl jasnou, znik a zdar
a tu sílu, vzdoru zmar?
To je Čechů slavné plémě,
mezi Čechy domov můj,
mezi Čechy domov můj!

Important part being:
mezi Čechy domov můj,
mezi Čechy domov můj!

My home is among Czech people, My home is among Czech people.
