- Please follow the discussion in the photo upon answering the problem below. Please provide an explanation for me to understand. Thank youuuu. Problem: A three bottom 40 cm Disc plough has a working depth of 20 cm, field efficiency is 80% and working speed is 4 km/h. Find the actual field capacity of the plough.1.1 Microbes in the soil could be beneficial to plants and one way to evaluate this is by determining the R/S ratio. Define the R/S ratio. 1.2 Both rhizospheric and root-free soils were collected from five (5) plants before (BT) and after (AT) treatment. Using the microbial biomass that appear in Table 1, the R/S ratios before (BT) and after (AT) can be determined. Use these values to determine the respective R/S ratios. Kindly show all workings. Microbial population Before Treatment (BT) Plants R/S Microbial population After Treatment (AT) R/S ratio ratio (BT) (AT) Rhizospheric Non- soil (CFU) Rhizospheric Non- rhizospheric soil (CFU) soil (CFU) rhizospheric soil (CFU) Typha sp. 764 168 988 186 Pistia sp. 286 86 386 112 Salvinia 397 132 528 166 sp.

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=-20
- Draw the NPK economy by showing how these nutrients are being added and lost in the soil system (Just a simple illustration-Boxes and Arrows with labels/descriptions - is enough to illustrate the soil nutrient economy) Each of the soil nutrient, N-P-K, should have a separate hand-drawings. Thus, there will be three (3) drawings.According to the water potential values shown in the image, which ones are wrong and why? W air (22 °C, 50% HR) -100 MPa Cas V sheet -0.2 MPa W stem -0.01 MPa to -0.1 MPa W soil -1 MPa to -0.51 MPa -4 MPa W root -0.1 MPa to(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.

- Sheep and cow manure are used as inorganic fertilizers by farmers and gardeners. Question 12 options: True FalseSoil 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?Which criteria helps determine which fertilizer to use.Group of answer choices a. Does it contain the needed nutrients? b. Does it readily release those nutrients? c. Expense d. Side effects e) All of the above
