I'm trying to find with my little eye, a web novel recommendation! Something similiar to https://www.novelupdates.com/series/chronicles-of-the-hardships-of-komachi-in-the-sengoku-era/ Like how it's informative, has a setting (historical sengoku in the above case), and kinda fun to read. Maybe farming related?
Not quite sure what you're looking for, but as far as farming & animal husbandry I'll recommend the manga Gin no Saji
This is an old manga, it got an anime too, it is informative, has a setting and is kinda fun to read (to borrow your words) but it is not farming related The manga is called 'Sangokushi'
