Herbicide Application Log — Main Cropping System Experiment (MCSE)
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
A record of herbicide usage and its rate of application to MCSE Treatments in all Replicate Blocks (1-6) at the LTER Main Site. Consult table KBS004-008 or browse the aglog at https://aglog.kbs.msu.edu,/a>, if needed. Application rates are generally in the amount of commercial herbicide solution per hectare
This datatable is part of the Agronomic Practices of the Main Cropping System Experiment dataset.
This dataset includes information on the agronomic practices of the Main Cropping System Experiment (MCSE), including the LTER Main Site treatments (T1-T8) and the Mid-successional (TSF) and Forested (TCF, TDF) sites.
Most long-term hypotheses of the KBS LTER are tested within the context of the MCSE. The LTER Main Site contains 7 different cropping systems (T1-T7) established in 1988 on a 48-ha area divided into 6 replicate blocks (R1-R6) of seven 1-ha plots. Each system is replicated in each block. The eighth system (T8) is a mown grassland on never-tilled soil, located 200 m off-site and replicated in four 0.06 ha plots.
Current MCSE treatments at the LTER Main Site include:
- Conventional (T1): standard chemical input corn/soybean/wheat rotation conventionally tilled (corn/soybean prior to 1992)
- No-till (T2): standard chemical input corn/soybean/wheat rotation no-tilled (corn/soybean prior to 1992)
- Reduced Input (T3): low chemical input corn/soybean/wheat rotation conventionally tilled (ridge till prior to 1994), with a center prairie strip planted in each replicate in 2019
- Biologically Based (T4): zero chemical input corn/soybean wheat rotation conventionally tilled (ridge till prior to 1994), with a center prairie strip planted in each replicate in 2019
- Poplar (T5): Populus clones on short-rotation (6-7 year) harvest cycle
- Switchgrass (T6): planted in 2019 and converted in 2018 from continuous alfalfa, replanted every 6-7 years)
- Early Successional (T7): early successional community on historically tilled soil abandoned in 1989 and burned annually since 1997
- Mown Grassland (Never Tilled; T8); successional community on never-tilled soil, mown annually since 1960
In 1993 three additional successional sites were added to the MCSE to provide reference communities for population and process comparisons. All are within 3 km of and share the same soil series as the LTER Main Site. These include:
- Mid-successional (TSF): three old-field sites on historically tilled cropland abandoned in the 1950s and 1960s
- Coniferous Forest (TCF): three conifer long-rotation plantations established in 1965
- Deciduous Forest: three deciduous forest stands, two old-growth and one logged once ca. 1960
For each treatment (and for some, microplots nested within treatment plots) the following variates are routinely measured (described in greater detail in associated datasets):
- plant characteristics including species distributions and abundances, aboveground net primary production by function;
- soil chemical and physical characteristics, including soil moisture, pH, inorganic N pools, total C and N, and bulk density;
- soil biological characteristics including greenhouse gas fluxes, soil leachate, N mineralization potential (buried bags); and
- insect dynamics including distributions and abundances of major insect pests and predators.

2023-07-03 | T8 | R1 | T8ntR1 | Herbicide Roundup PowerMAX 3 | 2.11 | Herbicide application to GLBRC G1 all reps(1, 2, 4, 5, 3), Bait Crop area (corn and soybean), LTER T8nt plots, LTER CE Study corn (CE1 and CE3), and planted area of the Lysimeter field. RoundUp Power Max 3 at 30 oz per acre and Ammonium Sulfate at 3.4 lbs per acre were applied post-emergence to control grass weeds. Application in the GLBRC began at 10:15 am and concluded in LTER at 12:45 pm. Rate of spray was 20gal/acre on JD rate controller. John Deere 7420b tractor was used instead of 5220 due to concerns over the current height of the corn. REI is 4 hours, safe re-entry on Monday July 3 at 4:45 pm.
