Document Summary
Focus: cultivation and agriculture, landesque capital, peru-coast- early collapse study. Investment in immovable facilities like homes, food processing equipment, and storage facilities. Accumulation of material good beyond the immediate biological needs of the people. Cultivation: intentional preparation of fields; sowing; harvesting; storing seed. Agriculture: a reliance on cultivated plants, often with changes in social and economic organization. Soil is the product of a range of factors: parent material, topography, climate, organisms, time. A: much biological activity; microorganisms enrich it with decomposing matter and nutrients; dark because of organics. C: results from the weathering of underlying bedrock. Plants compete with each other, and the composition of plant communities in any particular habitat changes with time- process known as succession. Humans artificially push back the extant succession stage to one that is early in the sequence and that has a very high output radio. Agriculture landscapes represent altered recovery rates of plant ecosystems.
