Charging fertiliser?

Question

Referring to electrostatic crop spraying.

Why is it unlikely that a farmer would actually buy the energy (needed to positively charge the fertiliser) from an electricity board?

In what form would the farmer buy the energy needed?

Answer 1

The two previous answers are to the point, but consider the generality that the cost of food gets to be excessive when the farmer must rely on purchased items, especially power. If anyone on this planet has more potential, the farmer has it with regard to energy production. Given all the available land and biomass, an ingenious farmer should never need outside energy at a cost of a small amount of time and resource.

Answer 2

electrostatic spraying the you are referring to is most commonly used when applying pesticides to crops not fertilizers but to answer your question the power supply would come from the alternator on the sprayer so the form of energy the farmer would buy would be diesel fuel

Answer 3

First of all, you don't really want the fertilizer sticking on the leaves.  Larger amounts can burn the leaves.  The power supply would be from the sprayer's alternator.
