This process may be accomplished by having less successful players imitate the more successful strategies, or by eliminating less successful players from the game, while multiplying the more successful ones.
Print By Science Buddies on March 30, For some, tilling their fields is a thing of the past. By Kim Mullin Photo: USDA Natural Resources Conservation Service When you think of a farmer at work in the fields, do you picture a tractor pulling a plow and turning the soil?
In my mind, it is a red tractor, and the soil is rich and dark. For many people, turning the soil may be an obvious part of growing crops.
Of course it is required! Isn't that what farmers do!?! It turns out that the answer to that question isn't easy. Yes, many farmers turn, or till, the soil. But increasing percentages of farmers are opting not to till some or all of their fields, for a variety of reasons.
As farmers prepare to plant new crops this spring, they must weigh the pros and cons of till and no-till farming. On the one hand, tilling a field in preparation for planting aerates and warms the soil, and also buries weeds, animal waste, and leftover crops. However, once the soil is turned, it is much more vulnerable to erosion from wind and water and is likely to have increased run-off of soil and chemicals into local waterways.
On the other hand, leaving a field untilled allows leftover crops to act as mulch and helps protect the soil from erosion and run-off. However, planting seeds through this layer of mulch is more difficult and requires expensive machinery.
This method also may require more herbicide to control weeds, and, in some places, crop yields may be lower because the mulch keeps the soil cooler and seeds germinate later in the season. Can you Dig It?
Science and Farming So what is a farmer to do? With no one right answer, farmers must experiment to learn what works best with their soil and the crops they choose to grow. Do you have an interest in the science behind farming?
Try out these Science Buddies Project Ideas: Run your own till vs. Earthworms do their own tilling and aerating of the soil. With worms, grass clippings, and a few pots of soil, you can see for yourself how effective they are at this job.
May the Best Plant Win! Experiment with Genetically Modified Seeds: What type of seed to use—conventional or genetically modified—is another choice that many farmers face.
When fertilizers are applied to farm crops or gardens, how much of it is absorbed by plants and soil, and how much makes its way into local waterways?
Create a run-off simulator to find out! Bacteria Can Fix It! Plants need nitrogen to grow, but what is the best way for a farmer or gardener to deliver it?
Grow clover with nitrogen fertilizer and nitrogen-fixing bacteria and compare your results. Getting Dirty in the Name of Science Spring is a great time to talk with kids about plant life cycles.
Dig in the dirt, plant a few seeds, or just head outside and observe how plant life is changing as the weather changes where you live.When you think of a farmer at work in the fields, do you picture a tractor pulling a plow and turning the soil?
In my mind, it is a red tractor, and the soil is rich and dark. Banks controlled the farmer by the neck, casting their shadow on the farmer's every step and relentlessly taking over the mortgages of farmers who couldn't make payments on their loans(doc d).
Generally speaking, the average farmer struggled during the period in part to the enormous increase of agriculture worldwide. First, the farmer travels across the river with the chicken, leaving the fox with the bag of corn on the other side.
When he gets across the river, he leaves the chicken. When he travels back across the river, he retrieves the fox. A farmer’s dilemma There is a saying that goes "The best thing about the good old days - is the fact they are not coming back".
Being the sixth generation farmer on the old family property, Mogens Haugaard Nielsen is a modern farmer with a long running history of farming the soils of Stevns in Denmark.
The farmer's dilemma is game-theoretically equivalent to chicken. Both of us choose to either cooperate by digging the ditch ("swerve" in chicken), or defect by sitting at home ("straight" in chicken).
