This mod is an overhaul of vanilla agriculture. This mod changes vanilla plants significantly. There are also a few changes to agricultural creatures. This mod should be installed after any mods that change the vanilla civilizations, and is likely not compatible with other mods that affect vanilla plants.

DFHack is strongly recommended to avoid issues with obtaining crop seeds and maps becoming covered in dead plants. This mod contains two automatic DFHack scripts that provide an intended gameplay mechanic (harvesting plant growths) and a quality of life feature (dead plant decay). It is still possible to play with Advanced Agriculture without DFHack, but obtaining the necessary plant growths may be a bit tedious using the vanilla "Process plant" job. Both scripts can also be disabled if desired. These scripts are active by default if a world is created with Advanced Agriculture, but will be inactive on worlds without Advanced Agriculture and will automatically disable when you quit a world.

This version of Advanced Agriculture is not compatible with DF 52.02 and before.

The Steam and Itch.io version of this mod (with graphics) can be found here.
The pre-DF52.03 version of this mod can be found here.

I recommend lowering the individual seed cap to 50 and raising the fortress total seed cap to 30000 in the game settings if intending to farm above-ground crops.

Some features include:

• Realistic biomes: Plains and marshes are grasslands and conifer forests are no longer dominated by fruit trees!
• Realist farming times: Most crops take multiple seasons to grow, and wild plants produce growths at the correct time of year.
• Dead shrubs and tree saplings decay after a month instead of cluttering the map
• Crop plots produce useful plant growths when harvested
• Added a lot of new reactions to allow selection of the types and amounts of products desired
• Added reactions to obtain seeds without having to process products from the plants or growths
• Seeds are no longer cookable, to prevent issues with job cancellation spam and loss of replanting
• Fixed certain plants being impossible to farm, notably beans
• Made all domesticated plants available to farm in all non-freezing biomes
• Wild farmable plants are still only available in their (approximate) native biomes
• Underground plants can be grown year-round
• Added the ability to make flour and plant milks to quite a few species
• Added, changed, and removed a few types of drinks based on realistic production
• Added dyes to several species
• Added the ability to obtain tree saps and process it into drinks, syrup, and sugar
• Changed the value of many plant products to be more balanced
• Changed how many plant products are processed to be more consistent and convenient
• Added value to certain types of wood based on characteristics and/or difficulty to obtain
• Removed bumblebee food materials to prevent food preferences for them
• Made honey bee products more valuable and doubled production of honey from hives, mead is cookable
• Removed royal jelly from honey bees because it was mostly an annoyance and not realistic
• Fixed feather tree eggs melting in the trading depot when brought as a trade good
• Fixed nuts having weird issues when selected on embark and in stockpiling
• Changed cattails to farmable shrubs instead of grasses
• Split bayberry into bayberry and wax myrtle trees. Bayberries have edible berries while wax myrtle can be used to produce wax.

The Steam discussions for this mod contain more detailed information about the changes included in this mod. You can also check this spreadsheet for detailed information on which plant structures produce which products and which wild plants can be found in specific biomes.

This mod includes an embark profile for starting with all of the available seeds and enough of each brewable plant to produce one barrel of drink. It also includes DFHack work order files for keeping seeds and one barrel of every drink in stock.
