Safe, long term agriculture/trades investments for a young person looking to diversify?

I realized my (23) portfolio is mostly tech. I’ve got a good amount of Vanguard ETF and some random stuff like John Deer and BlackRock, but I’m definitely lacking in diversity.

What are some good options to safely diversify into sectors a stupid young person like me wouldnt typically think to invest in, but a well rounded portfolio “should” have?

I’m thinking things like real estate(I obviously can’t afford to buy a house), agriculture, metal work, etc.

I’m working full time at 25/h (CAD) so I’m not rolling in it but I feel I’m in a position to start thinking long term.
