13
Q

challenges of irrigation

A
  • costs of setting up
  • increased water logging of soil

Q

why does aeroponics help

A
  • plants grow faster
  • easier to ensure plants have all the nutrients they need
16
Q

challenges of aeroponics

A

expensive

17
Q

what are hydroponics

A
  • plants grown in water
  • roots are planted in nutrient-rich water
18
Q

why do hydroponics help

A
  • plants get more nutrients
  • less space
  • no disease
19
Q

challenges of hydroponics

A

expensive

20
Q

the ‘new’ green revolution
