Why agriculture in South America is not as efficient in the US?

In some parts of South America agriculture is every bit as efficient as in the US. It depends on a lot of factors. Economics of the farmers has a lot to do with the technology available. Also the political environment can have a lot to do with agriculture efficiency or even the incentive to produce. The land and rainfall has much to do with the ability to have successful agriculture production. In the US there are many areas that cannot produce crops efficiently or at all. So comparing agriculture in one country or area to another it is not really a valid comparison unless all things are taken into consideration.

Where in South America? Are you talking about savannahs, or rainforest, or? Might be interesting to contrast and compare : Mechanization Fertilization Pesticide use General (base) soil fertility Climate Crop Genetics Average Farm size

ive read that brazil is more efficient than the u.s. there are million acre farms. they have all of the technology that we have they sometimes substitute with smaller low end machinery because labor is cheap. foreign investors provide all of the money needed some american farmers are diversifying by starting farms in south america. the climate is like a green house land is cheap the biggest obsticle is transportation but its being improved rapidly. they are using the amazon like we use the mississippi except the amazon is bigger and deeper allowing larger barges. the railway they are building will use trains that are much larger than ours.

South america is not as efficient because of technology,and a varieance of temperature,water supply is not as efficient and they dont have the finacing available to get equipment needed to make and harvest a crop properly. plus the local farmers dont have the education available that we have here in the USA

I have been to Brasil 8 times The biggest problem Brasil has with their growing is getting it out of the farm land and into the many ports or airlines for distribution. THE RAIL SYSTEM IF ANY IS ALMOST NIL. Brasil is larger the the Continental U.S.. What transportation there is is done by trucks and most of the roads are horrific. I travelled by car from Sao Paulo to the Pantanal in Mato Grosso do Sol and only saw one rail line that travelled to the northern shipping ports. I think in Sao Paulo we crossed one rail road crossing. Brasil could become the Bread Basket for the world without destroying any of the Rainforest. They have the capability for labor,climate and knowledge to compete with the world. It won't happen over night. We drove for hours and all we saw was Sugar Cane Fields for miles upon miles. Talk about being able to develop Bio- diesel refineries. Right now the alcohol is being used to make "Capirinas" Brazilian national drink. There's an awful lot of coffee in Brasil, as well as bananas, oranges and tons of other food. Cattle farming, dairy and beef are very large and they have to get the dairy and beef to market and fast. If you can't get it to market why grow it. More than two thirds of Brasil is tropical or subtropical There is only a couple of the states in the south with any winter. I would think the same for the other parts of South America. I think Bolivia and Paraguay are the only two countries without a coast line. The back bone (Andes Mt. Range) hinders some growing. I would imagine there is coffee to be grown in the mountains

hotter summers,colder winters and no money to buy fertilizer and mechanical aids.

A lot of the mechanization isn't as availabe to South america that it is in North america. A lot of product spoils before it gets to market. Just a poorer economy can't function as smoothly for the most part.
