Hello everyone i have a minor problem here.. I recruit a lord but he doesent recruit soldiers, or atleast he haven't for 2 weeks.
And I have a question to, how can i get trade agreements with other kingdoms ? 
The lord can be slow on recruiting soldiers. Be sure that he has at least one fief (village, castle or city). It can take more than 1 month before he recruits, and even longer before he is done. Try giving him marshal and see if that helps him recruit, it gives him extra money.
To have a trade agreement with other kingdoms you need to be recognized as a faction leader. You get recognized by sending an emissary with a letter of goodwill from one monarch to another, and it requires higher Right to Rule (found in character report notes), decent relations with the factions, and decent relation with the king, to work.
To get relation with the king try to duel him alot once you have high renown
