Which of these factors is associated with sustainable farming ?

D. Drip irrigation

Sustainable farming can be defined as a farming way which meets the societal norms without endangering the future generation agricultural needs.

Drip irrigation is an irrigation method that helps in saving lots of water and fertilizer. In this technique, the water drips slowly to the roots of plants through a network of valves, pipes and emitters.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
