Question
Miley Greenjeans, Pedro Greenjeans’ daughter, lives at the top of a gentle-sloping hill in southern New England. She has a few trees and a nice lawn in the front yard. Miley is concerned about bacteria from dog poop in her yard, and sprays her lawn regularly with a bactericide. She applied a squid-based fertilizer (which contains only organic forms of N) to her lawn. Miley uses a mulching mower, so the grass clippings stay on her lawn. Use this information as necessary to answer
91. The soil organisms benefitting directly from the organic carbon compounds in the lawn clippings are:
92. Which group of nematodes is most affected by application of the bactericide?
93. Which of the following will not be affected by application of the bactericide?
94. Could the application of bactericide affect the release of plant-available N from the squid fertilizer?
95. How might bactericide application affect the decomposition of plant debris in Miley's Lawn
97. Which soil organisms will not be involved in biodegradation of the bactericide?
98. Miley majored in TWERK (Turf, Water, Environmental Resources and Kinesiology) at Ol’ State U. She knows that earthworms are good for her lawn, especially for removal of thatch, as well as nutrient cycling and aeration. She would like to increase the number of earthworms in her yard. Which kind of earthworm would do all the things Miley wants?
99. Which activities will the earthworms in Q. 98 carry out in Miley’s front lawn?
100. Which of the following represents a trophic transfer of C, nutrients and energy?
Explanation / Answer
91) all Nitrogen auxotrophs present in soil are benefitting directly from Organic nitrogen sources because they are unable to fix the various forms of Nitrogen
92)Beneficial nematodes belong to one of two genera: Steinernema and Heterorhabditis are commercially available in the U.S. Steinernema is the most widely studied beneficial nematode because it is easy to produce. Heterorhabditis is more difficult to produce but can be more effective against certain insects, such as th white grubs, and Japanese beetles.he Nematodes are effective against grubs and the larval or grub stage of Japanese Beetles, Northern Masked Chafer, European Chafer, Rose Chafer, Fly larvae, Oriental Beetles, June Beetles, Flea beetles, Bill-bugs, Cut-worms, Army worms, Black Vine Weevils, Strawberry Root Weevils, Fungus Gnats, Sciarid larvae, Sod Web-worms, Girdler, Citrus Weevils, Maggots and other Dip-tera, Mole Crickets, Iris Borer, Root Maggot, Cabbage Root Maggot and Carrot Weevils
93)Fungal and viruses are not affected by bactericidal sprays
94)Squis fertilizer promotes the growth of bacteria and other microbial organisms, while providing supplementary macro and micro nutrients
