A farmer has noticed that his soybean plants produce more beans in some years than others. 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.

- It is June in Fresno and the officials at the water district have just reduced your irrigation ration by 26%. 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. Option Vs (MPa) Vp (MPa) Vw (MPa) -1.90 0.00 -2.59 +0.13 -2.4 -2.09 -2.05 -2.28 +0.17 4.Why is the Nitrogen content of Fertilizers so important?Explain what’s the big deal about fertilizer entering water bodies? Be sure to describe the entire process.
- Which soil mineral is most likely to be leached away during heavy rain? O hydrogen ion (H+) O Potassium ion (K+) O chloride ion (Cl-) O Calcium ion (Ca2+) O Sodium ion (Na+)What 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 thatWhy is most nitrogen fertilizer added as ammonium ion?
- Plants absorb dissolved nitrates from soil and convert them into : Free nitrogen Urea Proteins AmmoniaCollege students have conducted an experiment to determine the deficiency symptoms of tomato plants that is placed in a hydroponic solution. Each bottle out of the six bottles except for the positive control has lacked a certain micronutrient. In the positive control, all the nutrients were provided. However, the control setup showed symptoms of micronutrient deficiency unexpectedly. College students later found out that the room has a very high relative humidity and the transpiration was affected. Theoretically, how will the thermoregulation of tomato plants be affected of transpiration will not occur?The high acidity of the soil means less capacity to bind positively charged ions. True or False?
- If you have an orchard having a soil with high infiltration rate then which irrigation method you will adopt for better plant growth and profit maximization?An extremely acid soil generally limits the availability of many nutrients in the soil. True or FalseHigh buffering capacity means the soil will retain more nutrients than soil with low buffering capacity. True or False
