Six Ways Agroecosystems Differ from Natural Ecosystems Try to stop ecological succession and keep the agroecosystem in an early successional state Monoculture: Large areas planted with a single species Crops are planted in neat rows Farming greatly simplifies biological diversity Plowing is unlike any natural soil disturbance Genetic modification of crops. Botkin and Keller Environmental Science 5e

Environmental Science 5e Botkin and Keller Environmental Science 5e

Environmental Science 5e Limiting Factors Limiting Factor: The single requirement for growth available in the least supply in comparison to the need of an organism 2 Types of Life-Important Chemicals 1. Macronutirents 2. Micronutirents Synergistic Effects: a change in availability of one resource affects the response of an organism to some other resource Botkin and Keller Environmental Science 5e

Increasing the Yield per Acre 1. The Green Revolution Programs that have led to the development of new strains of crops with higher yields, better resistance to disease or better ability to grow under poor conditions 2. Improved Irrigation Botkin and Keller Environmental Science 5e

Environmental Science 5e Organic Farming 3 Qualities It is more like natural ecosystems than monocultures It minimizes negative environmental impacts The food that results from it does not contain artificial compounds Botkin and Keller Environmental Science 5e
