Soil Types of Northeastern Brazil

The Northeast's diverse soils include:

• Lithosols: Shallow, over hard rock (granite/gneiss); well-drained, low fertility; need fertilizers.
• Red-Yellow Latosols (Oxisols): Deep, well-drained, reddish-yellow; moderate fertility; require nutrient replenishment.
• Gleyed Latosols (Dark Red Latosols): Deep, poorly drained, grey-brown/dark red; lowlands; suit rice/wet crops.
• Podzolic Soils: Sandy, acidic, coastal; low fertility; limited to subsistence farming.
• Massapê: Heavy clay, coastal Bahia; poorly drained; difficult but good for sugarcane.
• Tabuleiro: Sandy, well-drained, low fertility; coastal & interior; used for cotton, sugarcane, fruit.

Soil management is crucial for agricultural productivity in this semi-arid region.
