Barriers, bulldozers, controls, fires, mulches and row covers appear among the reasons why weeds do not spread from one farmer's land to another's. Weeds can grow by such reproductive means as rhizomes, roots, seeds and stolons. Bulldozing and fire control root and root-like expansions whereas barriers, non-organic and organic mulches, organic and synthetic treatments and row covers obstruct dispersal of seeds by weather, wildlife and wind.
Some farmers like to keep their farm from weeds. So they buy weed killers so weeds can't enter into their soil and grounds.
They often produce it themselves or they could be selling it on behalf of another producer.
They didn't. Most times there was not water available to stop the fires, and if there was it was on a rare occasion that the fire could be stopped. If a farmers was lucky he could get to his water pump before the fire spread and extinguish the flames. But like I said RARELY the fires could be stopped.
By farming this way, farmers could farm a lot longer on the same land as well as produce a variety of different crops.
One is monsoons which destroyed crops, and another is that farmers in the Indus Valley could only plant crops in the areas where the water from the Indus was direct.
Farmers could produce more. (APEX)
It could be as soon as they moved out, or as soon as they moved into another residence.
Potentially. AIDS is spread through infected blood, so if you pick at the scab enough to draw blood, that blood could infect another person.
Small farmers could lose their farms
Farmers could use the water to water the crops
Farmers that could not pay their debts, the amount of land they had was used to paythem off.

Farmers could organize to fight against railroads and corporate interests
