Crop Sequence Calculator Version 3.1

    The Crop Sequence Calculator software is an interactive program for viewing crop sequencing information. The Crop Sequence Calculator program is designed to assist agricultural managers determine workable cropping sequences for the northern Great Plains. Version (3.1) contains the previous version (3.0) and adds new information gathered from additional cropping sequence research, as well as supplemental information related to use of annual crops as cover crops.

    AgroEcosystem Performance Assessment Tool

      The AgroEcosystem Performance Assessment Tool is a computer program used to evaluate the agronomic and environmental performance of management practices in long-term agroecosystem experiments. The program employs a simple scoring method to quantify the performance of management practices using indicators grouped within agroecosystem functions. Management practices are evaluated on a relative basis using the method, thereby internalizing comparisons. Because of its specialized application to long-term experiments, the program is designed primarily for use by agricultural researchers.

      SPUR2

        SPUR2 DOS ver. 2.2 is a general grassland ecosystem simulation model designed to determine beef cattle performance and production by simultaneously simulating production of up to 15 plant species on 36 heterogeneous grassland sites. SPUR2 simulates grassland hydrology, nitrogen cycling, and soil organic matter on grazed ecosystems as well as rangeland production under different climatic regimes, environmental conditions, and management alternatives.

        SHOOTGRO

          SHOOTGRO emphasizes the development and growth of the shoot apex of small-grain cereals such as winter and spring wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.). To better incorporate the variability typical in the field, up to six cohorts, or age classes, of plants are followed using a daily time step.

          RZWQM2

            Root Zone Water Quality Model 2 (RZWQM2) is a whole-system model for studying crop production and environmental quality under current and changing climate conditions. It emphasizes the effects of agricultural management practices on physical, chemical and biological processes. RZWQM2 is a one-dimensional model with a pseudo 2-dimensional drainage flow. Crop simulation options include the generic plant growth model, DSSAT-CSM 4.0 and HERMES SUCROS models. It also can simulate surface energy balance with components from the SHAW model and water erosion from the GLEAMS model. An automated parameter estimation algorithm (PEST) was added to RZWQM2 for objective model calibration and uncertainty analysis.

            PhenologyMMS

              PhenologyMMS is a simulation model that outlines and quantifies the developmental sequence of different crops under varying levels of water deficits, provides developmental information relevant to each crop, and is intended to be used either independently or inserted into existing crop growth models.

              PAL

                Profit and Loss (PAL) Farm Budgeting Economic Software for Colorado Agriculture is a windows desktop software for analyzing farm operations budgets. The software was developed in cooperation with Colorado State University.

                iFEAT

                  iFEAT (iFARM Economic Analysis Tool) is a spreadsheet based tool developed to allow the user to assess current and potential management options for economic sustainability. The user can evaluate lease arrangements, input costs, government programs, and insurance options to arrive at the best economic combination of these variables.

                  iFarm Record Keeper

                    The easy to use iFARM Field Record Keeper spreadsheet-based tool was designed to help farmers keep track of field operational records. The tool is designed to be farm specific allowing the user inputs to be specific to their operation. Drop down menus are created from user input including field names, crops, tillages, fertilizer, chemicals, landlords, and storage locations. This information needs only to be entered once. After initial setup each field will be saved as a file with the completed information. Up to four spray operations can be entered per field with the spray reports satisfying current Colorado Department of Agriculture and EPA requirements for Restricted Use Pesticide (RUP). The one page field report meets the fundamental requirements for the current Conservation Security Program (CSP) requirements for record keeping.

                    HIRO2

                      HIRO2 (Hortonian Infiltration and Run-Off/On) is a spatially distributed rainfall-runoff model for event-based studies of space-time watershed processes. A grid-based routing hierarchy was defined over the watershed using the D-infinity contributing area algorithm. Computation of ponding time was included to handle variable run-on and rainfall intensity. The Green-Ampt model was adopted to calculate surface infiltration, and the kinematic wave model was used to route Hortonian runoff and channel flow. The model can handle input rainfall, soil parameters, surface roughness, and other properties that vary in space and time.
