This sounds like an interesting feature for the game! Having a production factory where players can create their own liquid fertilizer and herbicide adds a new level of realism and customization to the gameplay. It will also provide players with more options for managing their farms and optimizing their crop production.
The inclusion of Galpao as an optional feature is a nice touch, giving players the ability to further customize their production site to suit their individual preferences and needs. The pricing and daily upkeep costs for both the liquid fertilizer and herbicide production facilities seem reasonable, allowing players to invest in these production sites without creating a significant financial burden.
Overall, this addition should enhance the gameplay experience for players who enjoy the strategic elements of farm management and production. It will create opportunities for players to experiment with different production techniques and optimize their farming operations for maximum efficiency. I look forward to seeing how players will utilize these new features in the game!
