A number of management decisions are based on the annualized costs of owning and operating an irrigation system. Before developing land for irrigation, the first decision should be to determine whether the irrigation system will be economically feasible. In other words, Will the net income from the increased yields achieved by irrigation development exceed the additional ownership and operating costs of owning and operating the irrigation system over the expected life of the various system components.
After deciding to proceed with irrigation development, one is faced with many alternative design choices, including selection of which energy source to use for pumping the irrigation water, the type of distribution system, etc.
The IrrigateCost app models center pivot and gated pipe irrigation systems and the most commonly used energy sources on separate tabs making side to side comparisons between alternatives possible.
When computing a fair crop-share rental arrangement, one procedure is to list all the contributions that are required for crop production in a table (land, irrigation system, machinery, labor, crop inputs, etc.). Next to each input listed, the contribution each party is making is shown in adjacent columns; one for the landowner and one for the tenant. The columns are tallied and the percentage of the total cost that each party is contributing is calculated. The “fair” rental arrangement would be to divide the crop on the same percentage as the contributions that each party has made. Alternately, after the initial listing is done, changes are sometimes made in the percentage the two parties contribute toward certain inputs until contributions match a pre-determined crop share arrangement (e.g. 60/40 or 50/50).
The costs of owning and operating the irrigation system are some of the most difficult to identify when analyzing irrigated crop share arrangements. Much of the total cost of irrigation results from ownership costs and a large percentage of ownership costs are not annual out-of-pocket costs but rather are sunk costs, such as return on capital investment, depreciation, and taxes and insurance.
A complicating factor in some rental agreements results from who owns the various components. In some cases, the landowner may furnish the entire irrigation system; in other cases the landowner may furnish the well, pump and gear head; while the tenant may furnish the power unit and/or the distribution system. A need therefore exists for the analyst to easily estimate the ownership and operating costs for each major component in various irrigation systems so each party is credited with a fair estimate of the contribution he/she is making.
The data and formulas behind this app were developed by UNL Extension Educator Emeritus, Thomas W. Dorn, who most recently served in the University of Nebraska-Lincoln Extension Lancaster County Office. He initially developed this data for an Excel spreadsheet (IRRIGCOST)
The app allows multiple people associated with the same farm to access an emergency response plan. The app also allows for record keeping in the areas of rainfall, manure storage capacity, mortality disposal, waterline inspections, and maintenance of manure handling equipment.
This calculator is designed to do three things:
1) calibrate manure spreading equipment (calculate the amount of manure applied)
2) determine the amount of nutrients applied in the manure
3) estimate the economic value of that manure
This calculator is useful for farms of all sizes that utilize manure or compost as a nutrient source on their crop fields. The app also provides a mechanism for saving and emailing a record of each calibration and nutrient calculation for the purposes of farm record keeping. The nutrient calculations can be done using results from a lab analysis of a sample of manure from the farm or can be estimated using average values for different types of manure.
With the Nebraska 4-H State Fair app, you can...
* view the schedule
* check out all the results by project type, name, city or even county
* share your results from the app on Facebook
* view photos and videos
* keep updated on the latest happenings
* find your way with the fair maps
The State Fair is also a prime opportunity for 4-H'ers to:
* cultivate skills they've learned in 4-H projects
* put their life skills and good character to work
* discover areas they'd like to learn more about
* meet other kids and adults
We look forward to seeing you at the 2013 fair!
Market Journal is an educational outreach effort presented by the University of Nebraska-Lincoln's Department of Agricultural Leadership, Education and Communication and UNL Extension. Hosted by Jeff Wilkerson and produced by Kurtis Harms, Market Journal provides:
*current grain/livestock market commentary and analysis;
*weather, climate, and soil moisture updates;
*proven marketing and management ideas;
*risk management strategies;
*updates on current agricultural policy issues;
*practical advice from seasoned, working producers;
*opportunities to share information and ideas; and
*access to the resources of the University of Nebraska-Lincoln Extension
The app is made possible by University of Nebraska-Lincoln Extensions and the Nebraska Soybean Board.
Next, note the meter reading at the beginning of a time period (for example, when you turn the irrigation motor on) and at the end (for example, when the pivot has completed a circle). Enter only the numbers visible on the totalizer (rolling numbers, no decimals). If your meter totalizer has rolled over, you may need to enter a 1 in front of the ending reading to make the calculations work.
The app will calculate the amount of water applied to the given field over the given time period.
The content of this app is based upon the Nebraska Pumping Plant Performance Criteria (NPPPC) that is cited by irrigation design engineers worldwide (Scheusener and Sulek, 1959). Defining the original criteria involved manufacturer’s and Nebraska Tractor Test data and field evaluations of pumping installations. Since 1959, the diesel fuel standard was updated by Fischbach and Dorn, (1981).
A new pumping plant testing program is under way to update the Nebraska Pumping Plant Performance Criteria for all energy types. Average pumping plant test results conducted previously in Nebraska and elsewhere have been near 80% of the NPPPC. Tests conducted on relatively new installations in 2009 produced results that ranged from 82% for Diesel powered units to 92% for electric units. The project will continue and the update of the NPPC will be based on data collected by the UNL and other entities across the country (Kranz, 2010).
The app is funded by the University of Nebraska-Lincoln Extension in Lancaster County. The app is adapted from an Excel spreadsheet developed by Thomas Dorn, Extension Educator Emeritus, UNL Extension, available at: http://lancaster.unl.edu/ag/crops/Long_Term_Pump.xls
The Flint Hills International Children’s Festival is one of the largest children’s festivals of its kind in the nation and takes place in downtown Saint Paul on May 31-June 1, 2014. The festival features local, regional and international professional artists representing more than 25 countries on seven indoor and outdoor stages.
