Mapping the System P .3 Space Several major factors affect the spatial layout of the crops and different modules in the Polydome system. For crops alone, the primary considerations include: • • • • • • • • • • • Soil pH Soil type Water requirements Light requirements Plant Height and Spread Root Depth Nutrient requirements Labor requirements Crop Rotational Requirments Necessary Chill Hours Cold Hardiness To understand the impact of each of these factors on physical crop placement, we created maps that combined a number of the factors, arriving at progressively higher-level understandings of the interrelationships between the crops. Spatial considerations for fish, livestock, and mushrooms were made later on in the analysis - in the system optimization phase, and in considering the final layout of the greenhouse structure.
