Question
ding to a University of Nebraska-Lincoln study that was cited in your textbook, agricultural soil loss was reduced from over 5000 lbs per acre to less than 1000 lbs per acre during rainfall amounts over 2 inches by switching to what practice? (3pts) a. Cover crops b. Crop Rotation c. Planting GMO crops d. No-Till Agriculture 21. What are the two things that healthy soil has the ability to store or "bank' for the benefit of plants? (4pts) a. b. 22. One of the single most effective things that you can do improve soil qu (4pts) a. Fertilizer b. Water c. Organic Material d. Sand 23. During the 1800s in the into eastern United States, significant amounts of land were changed fre States, signi 14pts) a. b. c. d. Forest, Agriculture Agriculture, Urban Areas Forest, Urban Areas Pasture, Urban Areas and decrease 24. Urban Development can significantly increase rainfall compared to a forested condition.(4pts) a. Organic matter, temperatures b. Friability, Salinity c. infiltration, runoff d. runoff, infiltration 25. Which of the following is not one of the problems that affect soil quality? (4pts) a. Compaction b. Erosion c Urban Development uination with chemicalsExplanation / Answer
20. (d) no tillage farming,
no tillage farming technique in agricuture prohibit soil erosion and control soil loss. this technique is also usefull to increase infilterated water in the soil
21. soil provide all necessary element to plants to grow. there are two important and necessary things which are helpful for the growth of the plant are
a. water
b nutrients
22. plant needed a high soil quality for growth, with the time soil quality decreases because of frequent crop rotations. soil lack of nutrient because of it . so we need to increase the soil quality. one of the most effective single thing is organic material, which is useful to imrove soil quality. so the right option is
(C) organic material
23. during the 1800 in the eastern United States significant amount of land were changed from agriculture into urban area.
so the right option is (B) agriculture , urban areas
24. urban development significantly increase __runoff__and decrease _infiltration___ rainfall compared to a forested condition
because of urban development , concrete roads and structure prohibit the infiltration of rainwater into the ground. and runoff increases.
25. erosion ie leading soil loss, urban development leanding lack of soil watere and chemiscals affect the soil quality so there is only one option compaction which is not a problem for soil.
(A) compaction
