The sweet potato industry, although a high value industry, is becoming increasingly competitive. This underlines the importance of efficiency in minimising the loss of valuable soil. Large amounts of rainfall can result in the loss of soil on cultivated farmland. The loss of soil does not just affect the farmers it also affects the community The aim of the project was to increase awareness of soil health and to develop the best soil management practices for the Cudgen plateau. Figure [ 2 ] Water Way On the Cudgen Plateau, three adjoining landholders implemented soil conservation measures and strategies.
| Soil Erosion | Tree major practices | Rosa Flores 2/18/2013 | Three major practices that expose soil to erosion and how they can be corrected. Soil erosion is the loss of soil caused by particles being carried away by wind or water. Erosion moves the smaller particles first and hence degrade the soil to a coarser, sandier, stonier texture. The major causes of soil erosion are over-cultivation, overgrazing, and deforestation. They are creating problems to create a more sustainable society but it can be corrected.
Abstract Intraspecific and interspecific competition plays a major role in stabilizing environments. These mechanisms ensure that no species can go beyond its environments carrying capacity. The purpose of this lab is to determine the effects of density on biomass of plants and the effects of predators and abiotic factors in an environment. This will be tested with the spinach plant Spinacia vulgaris of varying densities in the same sized pots and with the use of P. aurelia, P. bursaria and P. caudatum divided into control and experimental groups. The results showed that the increasing of the density leads to a decrease in the biomass of plants and that the experimental groups are not much different than the control groups.
These machines were created not just to cultivate the land, but to also apply large quantities of chemicals to the crops to prevent insect infestations. However, this then caused the crop to have a tolerance to many chemicals, and ultimately these chemicals that have seeped into the
The major problems with cotton are that the plantations require a lot of herbicides and pesticides, they use a lot fertilizer and they use up massive quantities of water. Hemp however makes a stronger material than cotton that can be grown in several different climates, requires no herbicides or pesticides, needs no fertilizers and would consume a lot less water. Because hemp is more durable then cotton I would throw away less cloths and I would reduce my methane as well as my nitrogen emissions. The growing, harvesting and production of hemp textiles create significantly less greenhouse gases then the cotton industry and would be a fast and easy alternative to
and Weed control experts. Hypothesis If home-made and commercial herbicides are sprayed on weeds then the commercial herbicides will be more effective, because the chemicals are made by experts who know what chemicals kill and prevent weeds. Experiment Fill 2 different boxes and fill then with soil make sure to use the same type and amount of soil. Measure around one cup of grass seed and sprinkle it on the soil. Water the seeds daily until the grass is at least 1.5 inches tall.
It is also a weed suppresser to prevent other weeds from growing because it grows so fast and densely, it blocks out sunlight to other weeds that are trying to grow. This allows farmers to use hemp as a replacement for herbicides and reducing toxins into the ground and surrounding water sources. Hemp can be used to replace petroleum and plastic products and are still biodegradable so it reduces the amount dumped into landfills. Since hemp can be used to replace gasoline and petroleum essentially replacing oil this reduces the environmental risks and impacts of oil drilling. This is a major environmental impact made when off shore drilling accidents happen made seen to the public by the BP accident in April of 2010 where 200 million gallons of crude oil was “spewed” into the ocean.
They were masters of restoring nutrients to the ground and producing a great deal of food from their soils. Mayan peasants would slash and burn the rainforest and then wait for the ashy nutrients to go deep into the soil before they would farm. When farmers let the land rest, they are trying to make it fallow (fallow means the land was well rested and nutrient rich). These farmers knew that over-farming could ruin the soil and make it impossible to grow on again. When scientists look at dirt today, they can tell a lot about what happened in the past.
Based on your data, which type of soil do you think is best for agriculture? Explain your answer. Loam would be the best kind of soil to plant crops in because it is permeable but it takes low amounts of water to irrigate the soil. Farmers often have problems with soil erosion when they clear their fields after the growing season. Soil type is one factor that influences erosion.
Compare JVTF methods (such as crop rotation, pest management, or use of cover crops) with more traditional farming methods that have a negative impact on the environment. . They don’t use pesticides so not a good chance that the food will be tainted. Crop rotation is nice because its makes sure that you have room for your next seasons crops and they also can have sells on the leftover crops from last harvest. 8.
