- To acquire immobile nutrients, the root system must be:Group of answer choices A.)Actively growing B.) in an environment with adaquate available moisture C.) In an unsaturated soil environment D.) All of the abovearrow_forwardWhat are the main elements that determine soil capacity to produce higher yields? If a plant shows stunted growth as well as yellow leaves then what type of nutrients would be deficient? How to address the issue? Please please answer thatarrow_forwardThe 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.arrow_forward
- 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 abovearrow_forwardCrop rotation is a sustainable practice of agriculture in which different crops are successively planted on the same land to improve soil fertility and reduce pests and diseases. How is this practice sustainable across the three dimensions?arrow_forwardIf you were breeding cotton plants to have increased water uptake in dry soils, you could breed plants that contain more amino acids and carbohydrates in the root cells. Why would this be effective and why might it also negatively affect crop yield?arrow_forward
