File List Data.txt Description The data.txt file is a tab-delimited ascii file. It contains all response variables presented in this article. The first row contains the capitalized variable names used in column definitions below. Column definitions: 1. PLOT – An integer to identify the 32 experimental plots 2. N – A value of 1 (one) identifies an N addition plot. A value of 0 (zero) identifies a plot that did not receive added N. 3. P – A value of 1 (one) identifies a P addition plot. A value of 0 (zero) identifies a plot that did not receive added P. 4. K – A value of 1 (one) identifies a K addition plot. A value of 0 (zero) identifies a plot that did not receive added K. 5. BLOCK – An integer to identify the two blocks within each replicate. In the balanced, incomplete blocks design, one block in each replicate includes the treatments +N, +P, +K and +NPK and the second block in each replicate includes the treatments CONTROL, +NP, +NK and +PK.
