The practice of crop rotation uses nitrogen fixation to create fertile fields. First, aplant without a nitrogen-fixing relationship. such as corn, is planted. After theharvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting thenitrogen-fixing plant, however, it is plowed under. The cycle continues in thismanner. Crop rotation would allow the farmer to reduce which of the following?O Planting seeds.O Watering the fields.O The use of manufactured fertilizer.O The burning of fossil fuels by farm equipment.In the year 2000. specimens of Caulerpa taxifolia,a green alga used in tropicalaquariums, were found off the coast of California. Native to the indian Ocean, C.taxifolia is known for aggressive growth and an ability to compete with seagrasses.Jt is currently on an intemational list of invasive species. Which of the

The practice of crop rotation uses nitrogen fixation to create fertile fields. First, a plant without a nitrogen-fixing relationship, such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner. Which of the following is not an abiotic factor that affects plants being used in crop rotation? a) NH3 availability b) Soil temperature c) Herbivore density d) Oxygen concentration
The practice of crop rotation uses nitrogen fixation to create fertile fields. First, a plant without a nitrogen-fixing relationship, such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner. Why would nitrogen-fixing plants be plowed under instead of harvested? a) To increases usable nitrogen in the soil. b) To increase water retention. c) Nitrogen-fixing plants are not a food crop. d) To decrease bacteria in the soil.

denitrification occure in wetland soil because - 1 - The top thin layer of soil is oxidized and the soil layer below is reduced. 2 - The top thin layer of soil is reduced and the soil layer below is oxidized 3 - The top thin layer of soil is oxidized and the soil layer below is also oxidized. 4 - The top thin layer of soil in reduced and the soil layer below is also reduced
A farmer growing maize in Eastern Cape under rainfed and marginal soils approaches you and tell you that maize is no longer doing well under his farm. Some of the soil characteristic in his farm include waterlogging, high pH and low water holding capacity. Advise the farmer on why you believe grain sorghum will do well under his farm conditions.
Micronutrient deficiency is, or may be:Group of answer choices A.) pH dependent B.) affected by excess macro and secondary nutrients. C.) Is not as typical in acidic soil environments as in alkaline soil environments. D.) All of the above
Nitrogen availability is a limiting factor in crop production. * D. Disagree, because atmospheric nitrogen is about 80% and therefore nitrogen is readily available. A. Agree, because almost 80% of the atmospheric nitrogen (N2) is readily available. C. Agree, because atmospheric nitrogen must first be reduced to ammonia through N-fixation. B. Disagree, because only a small fraction of the atmosphere is composed of nitrogen gas.
