Crop Sequence Calculator 3.1 for the WebWelcome to Version 3 of the Crop Sequence Calculator. This program is designed to assist agricultural managersdetermine workable cropping sequences for the northern Great Plains. Cropping systems need to be inherentlyflexible to take advantage of economic opportunities and/or adapt to environmental realities. Therefore, thisprogram applies the principles of Dynamic cropping systems to help users select cropping sequences best suitedto their particular situation. The research data used to develop the Crop Sequence Calculator were collectedfrom no-till farming experiments conducted near Mandan, ND from 1998 to 2005. This version (3.1) contains theprevious version (3.0) and adds new information gathered from additional cropping sequence research, as well assupplemental information related to use of annual crops as cover crops. Users are asked to select the appropriatedata set for answering questions unique to their enterprise. The first data set is what we call Phase II. ThePhase II experiment consisted of predominantly cool-season crops, and the weather conditions were considerablywetter than average. The ten crops used for this phase are shown in the Phase II Crops box below. The Phase IIIexperiment used some of the same crops as the Phase II, but included other crops considered to be warm-seasoncrops. These crops are listed in the Phase III Crops box below. The crops used in both phases are highlighted.Precipitation received during the Phase III experiment was below average.
To use the program, the user should select the appropriate data set to use. This is done by selecting eitherthe Phase II or Phase III button beside the crop lists.*** Run Phase II ***
