He claims to always apply the same amount of fertilizer to the plants but he suspects the difference in crop yield may have something to do with the amount of water the crops receive. The farmer has observed that the soybeans on his farm usually receive between 0 to 0.5 inches of water per day, but he is unsure of the optimal amount of water with which to irrigate. Question: state a research question that will directly address the farmer’s problem.arrow_forwardWhich three soil colours would suggest the following conditions in the soil 1. Poor drainage 2.

- Considering the concepts of hydraulic lifting and water potential, which of the following statements is like not true about the figure/illustration below? * DRY DRY WET The water generally moves from wet soil patches to dry soil patches because the latter have lower water potential. A deep-rooted plant can send water to dry soil patches with lower water potential O while simultaneously absorbing water from deep soil layers with higher water potential. The plant has higher water potential than the wet soil patches, but lower water potential than the dry soil patches. The plant has lower water potential than the wet soil patches, but relatively higher water potential than the dry soil patches.arrow_forwardWhen Chris mows the grass, she faces a choice between discarding the clippings and leaving them on the lawn.

In the field, you determine that the water potential in your soil is -1.68 MPa while the water potential of your crop is -1.62 MPa. Question A. Is your crop able to take up water from the soil? Explain. Question B. It is now late August and your soil water potential is -2.10 MPa, fortunately, you have been granted one magic wish in altering the physiology of your crop to increase its ability to take up water, however, you must choose from one of the options below. Fill in the values denoted by the ? as needed, and select the option that will cause the greatest water uptake by your crop.
