Strock ----------------------------------------- DATA-SPECIFIC INFORMATION FOR: Full_Buffer.xlxs ----------------------------------------- This is the main experimental data. Each row is a unique plot each column is an experimental design or response variable. Blank cells indicate that no measurement was taken. 1. Number of variables: 21 2. Variable list: a. LOC: Location data. WAS (Waseca) and ROS (Rosemount) b. Year: Experiment year. 2018 and 2019 c. Rep: Experimental block according to field map d. Plot: Experimental plot according to field map e. Crop: Crop species. SB= soybean, PCG = Prairie Cordgrass AC= alsike clover, IWG= intermediate wheatgrass, IG=indiangrass, BB= big bluestem, Switch = Swtichgrass, PolyH= High diversity polyculture PolyL= low diversity polyculture, Corn = Corn (Zea mays L), Alfalfa = Alfalfa f. TRT: Crop species, numbered. 1= Switch 2= BB 3= IG 5= PCG 4=IWG 6=Corn/SB 7= alfalfa 8= AC 9 = PolyH 10= PolyL g. Site: Landscape position. Hill, Hillslop Dep, Deposition h. Dmkgha: sampleled dry biomass. kg per ha i. plantN: plant tissue uptake. kg per ha j. Date: recorded date of volumetric soil moisture reading k. Jdate: Julian date of volumetric soil moisture reading. l. %volume, 100-1000: volumetric soil moisture. Depths are in mm. m. NO3 0-50 (mg/kg): soil NO3_N reading from plots sampled at 0-50cm. values reported in mg/kg n. NH4 0-50 (mg/kg)soil NH4_N reading from plots sampled at 0-50cm. values reported in mg/kg o. NO3 50-100 (mg/kg): soil NO3_N reading from plots sampled at 50-100cm. values reported in mg/kg p.NH4 50-100 (mg/kg):soil NH4_N reading from plots sampled at 50-100cm. values reported in mg/kg 4. Notes: a. no biomass data was collected for prairie cordgrass as none established over winter. b. cells for soil NO3-N NH4-N at 0-50cm and 50-100 cm reading <0.1 mg/L*, < 0.10 ppm**, < 0.05 ppm* were considered as 0 in analysis due to extremely low values. Values for soil NO3-N NH4-N at 0-50cm and 50-100 cm where 2 values are reported (ie {Sheet' Fall soil 2018 SROC} cell E2) were averaged in analysis.
