Hydroponics, Nitrogen Cycle, Stoichiometry, Photosynthesis, and Half Reactions Test Review

advantages of hydroponics

efficient use of space with stacking and specific amount of plants per feet, different ways to grow, urban accessibility in food deserts by growing plants w artificial light/rooftops, pest avoidance, water conservation with less runoff and recycled water, no farm runoff to pollute+cause diseases from soil organisms

disadvantages of hydroponics

setup costs, constant energy consumption bc it uses more artificial light and powering the hydroponics system, dangers of power outages and technical difficulties

fill and drain systems

buckets are filled and nutrients are pubped back in with vertical NFT system with inert medium like claystones

drip systems

w medium dripped from above, traditionally for bigger plants

aeroponics

minimal root support; hanging, get nutrients from air rock; vertical system, misting with nutrient rich solution

Growing medium

plants grown in rock wool, coconut coir, or other non-soil substances that provide stability, moisture, and oxygen to plants

Haber’s equation for ammonia synthesis

N2​(g)+3H2​(g)⇌2NH3​(g)

Haber process

primary industrial method for producing ammonia with high pressure, high temperature, and an iron catalyust that mixes air nitrogen and methane hydrogen
