Positive Effects of Conservation Tillage
For centuries farmers have used plowing as a tool for weed control, and
in some cases to promote plant growth. At first man had used animals to pull
plows and other equipment, with the invention of the tractor work that would
normally be done with animals could be done more easily and quickly. Although
plowing has been a common and widely used tool for managing weed control,
there are many negative impacts associated with this method. Conservation
tillage is a method where some of crop residues, if not all of crop residues,
are left on the surface of the soil. Conservation tillage methods have become
popular in many areas around the world, and while many of the effects of
conservation tillage are still under research, many farmers have found that
it helps to not only protect the health of their fields, but also that it
saves both time and money.
Research shows that conservation tillage has many beneficial effects
such as the reduction of soil compaction, increases in biodiversity, higher
crop yields, decreases in erosion, reductions in fuel requirements and other
capital inputs for machinery, and up to a seventy percent reduction of preharvest
labor. Researchers are not the only ones that are noticing that
conservation tillage has a promising future which combines low labor
requirements with low erosion rates (Giere, 2002). In America, eighteen
percent of crop fields are managed using conservation tillage methods, and in
Paraguay ninety percent of fields are managed with conservation tillage
methods (Karasov, 2002). Though the percent of conservation tillage in the
United States may not be as high as other areas in the world, it is projected
that nearly eighty ...

Grazing Cattle as Being Less Efficient than Growing Crops "The beef in just one Big Mac represents enough wheat to make five loaves of bread. " This just shows that growing wheat is more efficient than grazing cattle as the five loaves lasts, on average for a family of four, about three weeks whereas a Big Mac only lasts one person a matter of ten minutes, if that! In this essay I am going to discuss whether or not grazing cattle is less efficient than growing crops. There are many perspectives to this argument. From a biologists point of view, plant foods are far more energy efficient than animal products because when you eat meat, a vast amount of energy is lost through the food chains, whereas when you eat plant foods such as wheat, no energy is previously lost because plants are the producers of the food chains.

They take pride in caring for the land, water and natural resources in several ways. One way is by using cover crops which are plants grown to protect the soil and put healthy nutrients back into it, while slowing erosion, controlling pests, and increasing organic matter. They also use crop rotation by planting different crops in the same field but during different times. This keeps the land fertile because not all of the nutrients are being used with each crop. Buffer zones are another technique farmers use to plant strips of vegetation between the fields and bodies of water to keep the soil out of the water source. No till fields are used to keep the soil in place when it rains, helping moisture stay in the

This is a form of rotational grazing. It is considered the best method of grazing. It involves the farmer dividing grazing areas into 20-25 paddocks. The paddocks depend on the size of our herd. Every day cows will graze one paddock. This method is based on the idea that each tiller has three actively growing leaves at an...
Farming has evolved from providing food only for your family to providing food for your whole community. This aspect really kicked off in Europe during the middle ages when a new crop rotation plan emerged. Crop rotation is necessary. If every year the same crop is grown on the same soil the plants will keep taking the same nutrients needed for its survival. Previously the farmers used the Roman system, which is a two crop rotation. With this system the soil never had a break, there was always a crop being grown (“Feeding” par. 8). The new crop rotation plan was a three crop rotation. This system is very different from the Roman system. Every third year the field will lay fallow being used for pasture. When the field is used for pasture, the animals waste is spread out all over the field while they graze...

Organic farming has mushroomed drastically in importance and influence worldwide from its modest beginnings in the first half of the last century. Organic farming is production of food and livestock without the use of herbicides, pesticides, weedicides, fertilizers or genetically modified organism and use natural resources such as manure and compost instead. In other words, it is a production system which maintains the quality of soil ecosystem as well as human beings. According to IOWA State University, “the chemicals were not used for farming before World War 2. A number of munitions used in farming have contributed to field of agriculture.
