JECAM | Joint Experiment for Crop Assessment and Monitoring

USA - Michigan

Project Overview

Areas of investigation
We propose two scales of investigation; large plot and landscape.
For the large plot scale, two experimental sites in Michigan are proposed:

For the landscape scale, we propose to investigate the

This area covers nine counties in Michigan and four counties in Wisconsin. The Michigan counties encompass the large plot scale sites.

KBS LTER MCSE

Site Overview
A general site description of the KBS LTER and surrounding area can be found at http://lter.kbs.msu.edu/research/site-description-and-maps/general-description/.
 
The dominant soil series in the area are the Kalamazoo (fine-loamy, mixed, mesic Typic Hapludalfs) and Oshtemo (coarse-loamy, mixed, mesic Typic Hapludalfs) series. These soils occupy nearly level to rolling slopes. The Kalamazoo series consists of well drained soils that are moderately permeable in the upper part of the
profile and rapidly permeable in the lower part. More information is available at: http://lter.kbs.msu.edu/research/site-description-and-maps/soil-description/.
 
The Main Cropping System Experiment (MCSE) is the signature long-term experiment at KBS LTER. It was established in 1989 and is comprised of 4 annual crop treatments, 3 perennial crop treatments, and 4 successional communities. Seven treatments are located at the main site complex (http://lter.kbs.msu.edu/research/long-term-experiments/main-cropping-system-experiment/). Successional and Forest sites are located nearby (http://lter.kbs.msu.edu/research/long-term-experiments/successional-andforest- sites/).
 
 
GLBRC Scale-up Experiment
 
Site Overview
The GLBRC Scale-up experiment includes seven fields at two locations (Marshall Farm and Lux Arbor Reserve).
All Marshall Farm fields were in the USDA Conservation Reserve Program (CRP; since 1987).
An eddy covariance flux tower is positioned at each of the seven sites. These towers measure the flow of CO2 into and out of the crop canopy and soil, allowing a complete carbon budget to be constructed. This provides information on rates of carbon sequestration and loss from these different systems.
 
GLBRC RIMAs - Great Lakes Bioenergy Research Center Regional Intensive Modeling Areas
 
Site Overview
The GLBRC RIMAs are multi-county areas in Michigan and Wisconsin used for quantitative modeling of biofuel
cropping systems at landscape scales.

Implementation Plans

KBS LTER MCSE

All 11 treatment plots are assigned to a ~1 ha plot in 1 of 6 replicate blocks for the main site complex (87m x 105m) and 1 of 3 or 4 replicate blocks in off-site forest and successional treatment plots. Each plot also contains a permanent set of 5 sampling stations at which most within-plot sampling is performed.
 
The four annual ecosystems are corn – soybean – winter wheat rotations managed using:
(i) Conventional chemical inputs and tillage
(ii) Conventional chemical inputs and no-tillage
(iii) Reduced chemical inputs, and
(iv) No chemical inputs, i.e., biologically.
 
The latter two treatments include winter cover crops: red clover inter-seeded in the spring into the wheat phase of the rotation prior to corn, and annual rye planted following corn harvest prior to soybeans.
 
The three herbaceous and woody perennial ecosystems are:0
(i) Alfalfa
(ii) Poplar clones, and
(iii) Coniferous forest plantation.

The four successional ecosystems with herbaceous and woody perennial vegetation are:
(i) Early successional ecosystem (abandoned from agriculture 1989; periodically burned after 1996)
(ii) Never-tilled grassland (herbaceous perennial vegetation mown annually)
(iii) Mid-successional ecosystem (herbaceous annual and woody perennial vegetation)
(iv) Deciduous forest (woody perennial vegetation)

KBS LTER MCSE

Biovariables, instrumentation and measurement frequency

A list of all the research protocols used at KBS LTER is at: http://lter.kbs.msu.edu/protocols


Parameters measured at the MCSE (with technique) include:

Soil

Plant/crop

Water hydrochemistry:

Includes: Ca, Mg, Na, K, nitrate, total alkalinity, chloride, sulfate, ammonium, PO4-P, TDP, DOC


Weather
A fully equipped weather station is located at the KBS LTER MCSE. Campbell Scientific sensors connected to a CR1000 datalogger takes readings every 10 seconds and stores hourly integrated values.

Parameters (and model/instrumentation details) include:

GLBRC Scale-up Experiment

Biovariables, instrumentation and measurement frequency
Eddy covariance system
Each of the seven towers are equipped with continuous measurements of major microclimate variables at 30- min intervals, including air and soil temperature, relative humidity and VPD, precipitation, photosyntheticallyactive radiation (PAR), soil moisture (0-25 cm, Ms), soil heat flux and net radiation. The flux is measured at 10Hz
frequency and processed for 30-min means following the standard protocols of the FLUXNET using the ECProcessor including WPL corrections, planar rotation, and u* correction.”

Leaf photosynthesis
Measurements that are directly measured or determined from photosynthesis light and CO2 response curves (AQ and A/Ci curves) in dominant and co-dominant species at each site include:

Leaf gas exchange

Soil respiration

Plant sampling

Specific Project Objectives & Deliverables

Large plot scale experiments
Goals and Deliverables as a JECAM site

KBS LTER MCSE
http://lter.kbs.msu.edu/

Overall Site Goal
To make agriculture more profitable and provide environmental benefits by studying how agronomic
management can better utilize biological resources in cropping systems to control pests, provide nitrogen, and
build soil fertility.

GLBRC Scale-up Experiment
(http://lter.kbs.msu.edu/research/long-term-experiments/glbrc-scale-up-fields/)

Overall Site Goal
These KBS commercial fields were established to provide a larger context for addressing biodiversity and
biogeochemistry questions associated with biofuel production, and are managed to replicate biofuel treatments
at landscape scales. The crops grown are similar to three of the GLBRC main site treatments
(http://lter.kbs.msu.edu/research/long-term-experiments/glbrc-intensive-experiment/).

GLBRC RIMAs - Great Lakes Bioenergy Research Center Regional Intensive Modeling Areas

Goals and deliverables as a JECAM site
To link imagery with crop models to help understand the economic, environmental, and social impacts of
alternative bioenergy cropping systems and the associated biorefining systems.
