The Incas developed terraced farming on Andean slopes, increasing arable land area. Their advanced irrigation techniques and understanding of microclimates led to diverse crops at various altitudes, optimizing food production.
Amazonian Soil Enrichment
Amazonian Soil Enrichment
Pre-Columbian Amazonians created terra preta, or 'black earth,' by enriching soil with charcoal, bone, and manure. This fertile soil sustained large populations and stands in stark contrast to the region's naturally infertile ground.
