Crop residue

Sediment can clog water pathways, reducing the useful life of reservoirs and increasing dredging costs. “By raising streambeds and burying streamside wetlands, sediment increases the probability and severity of floods.” (Aillery et al.) Vital crop nutrients like nitrogen and phosphorus that are applied to fields each year in large volumes can runoff or leach into water sources. A major environmental concern is eutrophication of surface water, resulting in decreased oxygen levels and death of…

structure, and no other chemical inputs. Hemp can be grown in already existing agricultural land, it can be a part of a farm’s crop rotation, it can grow in a diversity of soil conditions and climates. All other crops can’t grow this easy nor help as profoundly. Growing Hemp causes very low environmental impact. For instance, Hemp uses low fertilizer, reduced agrochemical residues, replaces unsustainable raw materials, reduce use of trees, replace…

Crossing certain crops to induce certain traits in offspring is not a new process. In fact, farmers around the world have used conventional breeding practices such as artificial selection to produce higher-yielding crops for centuries. Those practices were not frowned upon, but instead considered necessary if agriculture was to continue to support the world’s growing population. Today, we face a similar problem. The Earth’s population is expected to reach 9 billion by 2050, and world…

Since the dawn of time, agriculture has been the centre of humanity, where there was fertile land, there were humans. As time went on, this has not changed significantly, the biggest threat to crops now or thousands of years back in time, is still insects. As technology as improved, techniques for eliminating these insects has changed substantially. The most populate method in today’s age is insecticide; chemicals which kill insects, however as sometimes due to gene mutation some insects are…

great to live in the present but sometimes we have to put the future first. Genetic engineering (or GE) food started in the late 1990’s; 1996 to be more precise. We have been told that it’s better for the world, that it can help us produce more crops that are bigger and healthier; that it’s low cost, and we don’t need to use extremely harmful pesticides on them. We’ve been told that these GE foods have been developed in such a way that they have improved nutritional content and longer shelf…

consult their crops and get them out before erosion occurs. Livestock makes a very muddy field and then it rains. There go all kinds of danger down the creek bed. Soil structure influences the ease which soil can be eroded. Soil with a medium to fine texture, a low of organic matter content, and weak structural development are most easily eroded. Typically these soils have low water infiltration rates and therefore are subject to high rates of water. Soil structure is bad for damaging crops out…

chances of developing certain cancers. Organic crops contain far fewer pesticide residues than conventional…

Bees are insects that have a major job in the ecosystem, they collect pollen and nectar and pollinate flowers which in return provides many fruits and vegetables that are consumed on a daily bases, they are one of earth's most essential and diligent species of animals.Without them humans would not be able to survive as efficiently as when there are bees. Unfortunately, over the years the population of the bees has been declining in numbers for multiple reasons. The very existence of bees is what…

about pros and cons of genetically modified crops mentioned: The more a pesticide—or in this case a GM crop that produces its own toxins—is used, the more likely insects are to develop a resistance. Insect that become resistant to these toxins are harder to kill. While companies like Monsanto have advised farmers to rotate their crops every year to try and keep resistance at bay, many farmers do not follow these guidelines. As a result, certain GM crops are starting to lose their effectiveness,…

uneven geographical resources doomed some cultures to failure, but some to stardom. For example, Papua New Guinea was too wet to grow efficient crops crops, had no domesticable animals and because of that were stuck in the stone age until sixty years ago. In contrast, because of Europeans geographical location and climate, they had reliable and nutritious crops, nearly all the domesticable animals on earth (which just happened to provide immunity to diseases).…
