Variate Description Units
treatment N fertilizer treatment, see experimental design: https://lter.kbs.msu.edu/research/long-term-experiments/resource-gradient/
group number unique groupings of treatment by irrigation
replicate replicates within irrigation treatment. 4 replicates (blocks) of all 9 fert levels rainfed, and another 4x9 irrigated
plot plot number
block experimental block
is irrigated 't' if the plot is irrigated, 'f' if it is not.
irrigated mm growing season total mm of irrigation if irrigated millimeter
year calendar year
crop crop rotation: corn, soy, wheat
nfertcorn N fertilizer kg/ha treatment in corn years (listed as corn year for all years) kg/ha
nfert actual N fertilizer kg/ha treatment specific to crop kg/ha
limeton "ton/acre lime received (coded for 2012 only, all other years 0) tons/acre
lime kg kg/ha lime received (coded for 2012 only, all other years 0) kg/ha
lime full lime ton/acre received, 2012 level coded every year tons/acre
has lime applied received lime in 2012? 't'= true, 'f' = false
pH pH dimensionless
hconc H in H concentration, [H+]= 10^(-pH) mole/liter
harvest date date the crop was harvested
crop yield crop yield kg/ha
