Both plots received a total of 116cm of rainfall by the end of the year as measured by the rain gauges. By the end of the year, a total of 200kg of soil was collected from the plot B soil-collection devices and a total of 200kg of soil was collected from the plot C devices. Describe a practice or agricultural method that could have been used at plot B to obtain these results.

The missing data is as follows:

Local officials are concerned that agricultural fields at site B are increasing sedimentation in the river because of soil eroding from the fields. They hire an environmental consulting company to perform a study to determine if this is true. The company marks out two one-hectare plots at point B and point C in the diagram. The characteristics of the land in both plots are identical except that plot B is covered by agricultural fields and plot C is covered by undisturbed forest. Rain gauges are set up at the up-slope edge of the plots, and devices that collect eroded soil are set up along the down-slope edge of the plots. The environmental consultants hypothesize that more soil will be eroded from plot B than from plot C. Data are collected at the rain gauges and soil-collection devices at the end of each month for a year.

To measure the precipitation or the amount of rainfall, Rain gauges is one of them which is used to collect the rainwater. The type of soil can also be determined by the various tools and kits available. By the soli and its characteristic and composition soil can help in the practice of agriculture.

At plot B the results could have been obtained by developing a rainwater harvesting system that runoff on the surface, along the downslope edge which can show the rate of sedimentation caused by erosion.

the correct answer is c
