Fertile soil is one of the keys to good yield.
(i)
Explain the roles of clay and organic matter in contributing to soil fertility and cation
exchange capacity (CEC).
(ii)
Name ONE (1) negative effect of low CEC and high CEC soils respectively. Suggest
ways to improve low CEC and high CEC soils.
(iii)
Suggest ONE (1) suitable type of crops for high CEC soil, low CEC soil and loam soil
respectively.
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.

- 43. Two soil samples, A & B, at same soil moisture levels are placed in contact with each other. Water will more likely move from soil B to soil A if their osmotic potentials, expressed in kPa, are: O A=-30; B=-70 O A=-10; B=+10 O A=-60; B=-10 O A=-50; B=-100 OA=-20%; B=-20arrow_forwardSoil organic matter (SOM) samples have charge that is pH-dependent, and measurements for the cation-exchange capacities (CECS) of soil organic matter average around 150 cmol(+)/kg SOM at neutral pH. Meanwhile, smectite clay minerals have CECS that average approximately 100 cmol(+)/kg clay. Since these two phases are the dominant contributors to soil CEC, we can use SOM content and smectite content (if we can measure it) to estimate total soil CEC. What would be your estimate for the total CEC (in cmol(+)/kg soil, to the nearest 0.1 cmol(+)/kg soil) of a soil that contained 3.28 % SOM and 1.0 % smectite clay by weight?arrow_forwardA corn farmer has approached you with various leaf samples with symptoms shown as below.

- Malathion is an organophosphate pesticide that is used often in residential and commercial landscaping. A landscaping company came and applied the pesticide to a lawn and after a couple of days. An environmental science student sampled the soil and analyzed the pesticide content. The student found the soil concentration of malathion to be 6.26 ppm. Assume a soil organic content of 1.5%, a soil particle density of 2.0 mg/L, and a soil porosity of 45%. If it rains the next day and water mixes well with the soil, estimate the concentration of malathion in the soil water.arrow_forward(a) Fertilizer X is a complete fertilizer with a fertilizer grade of 25-25-25, it is the only fertilizer material needed to satisfy a recommendation of 120-50-60 kg/ha; (b) Fertilizer X (25-25-25), Fertilizer Y (0-0-62) and fertilizer z (0-50-0) are the fertilizer materials needed to satisfy a recommendation of 120-50-60 kg/ha.

- A genetically modified corn crop that is resistant to the herbicide glyphosate ("Round-Up") may contribute to conservation agriculture practices because: O The plants would thrive with less water, so they would not need to be irrigated as frequently. O It is not possible for any other organisms, such as weeds, to develop a resistance to glyphosate. O The plants would be resistant to pests, such as the corn borer, so would not need to be treated with pesticides. O All of these answer choices are correct. Because they could be sprayed with glyphosate, the soil would not require tilling to control weeds.
