How do farmers have Fields of crops with practically no weeds?
Question:
Answers:
They don't use roto tillers. Most now plant Round-Up Ready seed than can you can spray Round-Up directly on top of the crop and kill the weeds but not the planted material. It costs a whole lot more than conventional seed, but you don't have spend a whole lot of money targeting specific weeds as Round-Up kills most anything.
chemical weed killers.
Most farmers use weed killers and rototillers to get rid of weeds. Some use the black plastic and yet others use the black cloth. There are several ways. Check with your local garden center.
because they dont have any weeds
if you keep them out they cant spread
Roundup...Chemical that kills broadleaf weeds.
Chemicals and illegal immigrants
lots of chemicals
They plant "frankestein food" ( TM of Mosanto Corporation )ie it has been genetically modified so as when they spray highly toxic, poisonous chemicals on the crop to kill the weeds, the original seed crop ( like gm-canola or gm-corn ) is not killed, but lives. So the crop absorbs the poison in its cells and when you, dear consumer eat the gm-food , you absorb amounts of weed killing poison that will slowly over time help to kill you. Unless, of course you choose to not eat genetically modified food and choose normal food that god himself made for you.
Most of the farmers I know plow between the rows to dig up the weeds before they can take over the fields. Really large commercial farms probably use weed killers, but I don't know for sure. I have always lived on a small farm of only 150 acres.
They spray with a weed killer/fertilizer mixture. It controls the weeds and makes the crop grow better and faster.
Herbicides but also if you keep a field plowed and clean long enough then there are not many weed seeds to grow.
Another thing that might help you in a garden is the way row crops like cotton are cultivated. When cotton is planted it sprouts and comes up and with it often come many tiny grasses ( like Hoo-raw). The cotton will reach 4 or 5 inches tall in a short time. Like a week or two. At that time a farmer will cultivate the crop. That means he plows it with a plow leaving a gap for the rows of cotton plants and on the cultivator or plow are adjustable metal shields that run along each side of the plants. These are set so that they are about 2 inches above the ground. As the plow moves quickly through the field loose soil is thrown up beside the cotton plants. This soil essentially smothers the small grass plants leaving the taller cotton there alone. Two weeks to four weeks later the cultivator again is plowed through the cotton. This time the cotton is much taller and the shields or fenders are all the way up or missing. Much more soil is thrown around the cotton. Done properly the cotton is realtively weed free.
In the garden take your hoe and throw loose soil around the plants that are taller and the weeds and grass is covered and dies. The tomatoe, squash or whatever thrives.
Three ways that all work great together. Bio-mechanics, can be as simple as over seeding to keep the battle for space of what your trying to grow. Manual, is physically removing the weeds.(Pulling,trimming,and mowing.) And last but least is Chemical treatments, Using pesticides, herbicides, and fertilizer.
Herbicides. Also, when the plants get bigger, a cultivator is ran down the rows to loosen weeds.
Ever notice how organic gardens are full of weeds that have to be pulled.
