Farming in Tropico 6 is a crucial part of maintaining a stable economy and ensuring your island’s prosperity. However, many players encounter an issue where their high-efficiency plantations suddenly drop to single-digit efficiency levels. What went wrong? This guide will break down the mechanics of soil degradation, different plantation and ranch work modes, and strategies to maintain high agricultural productivity.

Farming Buildings in Tropico 6

At the start of the game, you have access to two primary types of agricultural buildings:

• Plantations – Used to grow various crops like sugar, tobacco, and coffee.
• Ranches – Used to raise livestock for meat and other products.

Later in the game, during the Modern Times era, you unlock two advanced structures:

• Hydroponic Plantations – These allow you to grow crops anywhere on the map, but they require electricity.
• Factory Ranches – Function similarly to ranches but allow centralized production. They require corn as an input to operate.

While these modern options offer superior efficiency and flexibility, early-game and mid-game farms must be carefully managed to avoid soil degradation.

Understanding Soil Degradation

Soil degradation occurs when the land’s ability to produce a chosen crop diminishes over time. If you’ve noticed a plantation that started at 85% efficiency slowly dropping to 0%, that’s due to soil exhaustion. This happens when you use the default work modes, which are:

• Monoculture (Plantation) – Maximizes initial efficiency but gradually depletes soil quality.
• Humane Exploit (Ranch) – Similar to monoculture, this provides high efficiency but reduces productivity over time.

If left unchecked, soil degradation can cripple your food supply and exports. Fortunately, there are several ways to mitigate this problem.

How to Prevent or Reduce Soil Degradation

1. Switching Work Modes

A simple but effective way to slow degradation is by changing the work mode of your plantations and ranches:

• Multiculture (Plantation) – Reduces efficiency by 40% but completely prevents soil degradation.
  • Bonus: Each neighboring plantation with a different crop in Multiculture mode increases efficiency by 10%.
• Pasture Prohibition (Ranch) – Lowers efficiency by 15% but stops soil degradation and generates manure, which can be used later for further soil management.

These work modes provide long-term sustainability, ensuring that your farms remain productive without suffering from diminishing returns.

2. Utilizing the Manure Spreader

The Manure Spreader is a special building that takes manure from ranches running Pasture Prohibition mode and distributes it to plantations. If a plantation is within its radius, the Manure Spreader will help regenerate the soil, effectively counteracting degradation.

Additionally, the Manure Spreader can be used on ranches still running Humane Exploit mode, helping them maintain their efficiency over time.

3. Enacting the Agricultural Subsidies Edict

The Agricultural Subsidies edict increases the efficiency of all plantations by 25%. However, this is a short-term solution because:

• It doesn’t prevent soil degradation.
• It increases upkeep costs.
• It works best when combined with other strategies, such as switching work modes or using Manure Spreaders.

Best Strategy for Long-Term Farming Success

The best approach is to balance efficiency and sustainability:

1. In the early game, use Monoculture mode for fast income but prepare for soil degradation.
2. Mid-game, transition to Multiculture mode and Manure Spreaders to preserve soil while maintaining productivity.
3. Late-game, unlock and switch to Hydroponic Plantations and Factory Ranches, which are unaffected by soil efficiency and location constraints.

By following these strategies, you can maximize your agricultural sector’s efficiency, ensuring stable food production and profitable exports.

Final Thoughts

Managing farms efficiently in Tropico 6 requires an understanding of soil degradation and work mode mechanics. While it might seem tempting to rely on high-efficiency Monoculture and Humane Exploit modes, these will eventually deplete your resources. By using Multiculture, Manure Spreaders, and advanced farming buildings in the Modern Times era, you can ensure a prosperous and sustainable economy.
