<br />fD <br />: 1 <br /> <br />. .. <br /> <br />(2) Border - The same as furrow and corrugation for all items <br />except 3b. (l)(b) furrow evaluation. <br />(b) Border evaluation. <br />a. Time checked. <br />b. Time of advance. <br />c. Water distribution across border. <br />d. Water height in relation to borders - any problem? <br />e. Time input the same as for furrows. <br />(3) Sprinklers. <br />(a) Flow rate entering system. <br />(b) Sprinkler evaluation. <br />1. Set up can test and gather data as per require- <br />ments for type of sprinkler checked. <br />2. Check for runoff from irrigated area. <br />3. Check for translocation of water in irrigated <br />area - movement of water further than 10 feet <br />after it hits the ground. <br />4. Check for eroding areas. <br />5. Check for soils having water penetration problems. <br />6. Time of set. <br />7. Acreage covered by sprinkler. <br />8. Pressure at 1st sprinkler and last sprinkler. <br />(c) Weather conditions. <br />1. Approx. wind velocity and direction. <br />2. Temperature - minimum and maximum for day and at <br />time of evaluation. <br />3. Rain. <br />~. Humidity - upward and downwind. <br />(d) Check operation of installed equipment. <br />1. Check nozzles for wear. <br />2. Use volt meter for safety. <br />3. Do sprinklers turn right? <br />4. Nozzle inserts right size. <br />S. Conditions of equipment - wheels, flow control <br />valves, pressure regulators, air vacuum valves, <br />leaks, other. <br />(e) Manday estimates. <br />1. Side roll, soil set, etc., estimate usually <br />3 inch net irrigation. <br />2. Center pivot - may have 1 to 2 inch net <br />irriga tion. <br />3. Estimate 10 irrigations per year. <br />4. Equipment levels 1,2,3, and 4 are not much <br />different. The level of accuracy required is <br />different. <br />a. Equipment level 1 10 days <br />1 man per irrigation. <br />b. Equipment level 2 15 days <br />1 man per irrigation - pick up <br />additional information the next day. <br />c. Equipment levels 3 and 4 15 days <br />1 man per irrigation and pick up <br />additional information before irri- <br />gations and after irrigations. <br /> <br />. -, <br />I. _ <br />'\.._~ <br /> <br />,'-. <br /> <br />52 <br />
