Q2: Wheat is to be grown in a field having a field capacity equal to 27% by weight and the permanent wilting point is 13% by weight. Find the maximum storage capacity in 80 cm depth of the soil (root zone depth), if the apparent specific gravity of the soil is 1.5. If irigation water must be supplied when the average soil moisture falls to 18%, find the water depth required to be supplied to the field if the water application efficiency is 80%

b) The open-air crop beds are 7952 ft2 in area. The soil is prepared to a depth of 24 inches. The soil is clay-loam, which on average has a water holding capacity of 3.2 mm water per cm depth. What is the total volume of water holding capacity in the prepared crop beds, in gallons?
Eggplant is planted in a well-drained, fertile, sandy loam soil. It has a maximum effective rooting depth of 2 feet. Soil samples were taken from the root zone to determine the moisture status of the soil at the time of irrigation. The apparent specific gravity of the soil is 1.6. The fresh weight and dry weight of soil sample is 100.2 g and 94.3 g, respectively. Determine the following: a. Moisture content in dry weight basis b. Moisture content in volume basis c. Depth of water in mm

1. 60,000 lb of shelled corn at 22 per cent moisture content (wet basis) are to be dried to 13 per cent moisture content. Determine: a. The dry-basis moisture contents. b. The amount of dry material. e. The gallons of water to be removed.
Ground cherry seeds need to be planted at a depth of 1-cm below the surface and will only germinate if their surrounding soil is at a temperature of 24-30°C. Farmer Joe wants to know whether adding straw mulch (mulch = 0.05 W/m K, Lmulch = 10 cm) on top of his soil will increase the odds of germination. The topsoil in Deleware is sandy loam (soil = 0.5 W/m K), with a thickness of 1 m. Immediately beneath the topsoil is the subsoil, which is at a constant temperature of Tsubsoil = 10°C. You can assume that the air in Deleware is fairly calm, with a heat transfer coefficient of h = 10 W/m².K. deleware (a) Sketch the system (with and without mulch), labeling all temperatures, dimensions, and proportionality constants. You may assume that the subsoil, topsoil, mulch, and air are at steady state. You should have two sketches. On separate graphs, sketch the heat flux and temperature as a function of position (from the air to the subsoil), with and without mulch. Make sure that your sketches…

After how many days will you order irrigation in order to ensure healthy growth of crops, if the field capacity of soil is 29%, PWP is 11%, Density of soil is 1300 kg/m³, Effective RZ is 700 mm, daily Cu is 12 mm. For healthy growth, moisture content must not fall below 25% of the water holding capacity of soil.
