Goodbye, Sarah!

After five fun and action-packed years, Sarah is off to greener pastures! She has recently begun a position as the Research Specialist in Organic Cropping Systems in our sister-lab, run by PI Chris Reberg-Horton. What a perfect fit for her! Below are pictures from Sarah's going away party in the Soil Science department. We will miss you, Sarah!

Sarah received lots of love from the lab!

A table highlighted some of the funnies from our experiences over the years

A 'thumbprint tree' was made in her honor

Lots of blue thumbs! (and pinkies for those of the group who thought their thumb was too fat)

National conference on cover crops and soil health

Greetings from Omaha!  I am here at the National Conference on Cover Crops and Soil Health with 299 other invitees to celebrate the contributions of cover crops towards enhancing soil health. And what an amazing bunch of folks it is!

Intended not only to highlight the latest information on cover crops and soil health practices, but also for participants to discuss the role of industry leaders, government agencies, farm organizations, scientists, and educators in advancing soil health and the use of cover crops, this event has been inspiring, to say the least. Both plenary and breakout sessions have focused on progress and prospects for further conservation advancements and the benefits for farmers and farm industries that are engaged with these practices. I can't express how exciting it is to have discussions with growers, funders, researchers and industry reps about what we love best - cover crops. The passion for furthering understanding of legume cover crops for nitrogen, carbon and overall soil health contributions is evident in every session. Smart folks.

A heartfelt thanks to the Howard Buffet Foundation and to SARE for having the vision to bring everyone together in one place!

A special day

The day was started by a "surprise" birthday party for Natalie. Even though, Natalie cannot eat cake but WE can so we decided to celebrate her day with a yummy carrot cake anyway and give her a bag of sweet potato chips home.

The celebration was followed by a small group meeting with Dr. Snapp, who was visited for Mary's defense.

And yes, later in the afternoon, Mary had turned herself into Dr. Parr!! Congratulations!!

Notables from the SSSNC Annual Meeting 2014

The annual NC Soil Science Society meeting was on January 21-22 at the McKimmon Center. This year, Sarah contributed her hard work and time to be on the committee of the meeting. Julie and JiJY gave oral presentations. Our graduate students, Sarah, Peyton and Natalie attended the poster competition for which cash prizes were given!!!

Please join us in congratulating Peyton and Sarah for their award winning in the graduate student poster competition!!!

1st place - Peyton Ginakes

4th place - Sarah Seehaver

2nd place- Boris Droz (our lab neighbor)

Sarah and JiJY happened to wear similar dresses.
No, we did not plan on doing that.

The Initiation

It has certainly been an interesting few months. Upon arrival at NCSU to study soil science I figured I would have some time to absorb information about my project, sit down to plan out a timeline of events, and THEN actually start working.

Getting to this point was the easy part. See more below.
Nope. Turns out that's not how graduate studies work - especially not mine. I had a couple of weeks to plan, but between classes, reading, research, and familiarizing myself with the locality I felt like I didn't spend nearly enough time learning what I was doing. Combine that with the impending shutdown of all of the facilities I was using and you get a rush to complete the initial stages of a project. I was basically learning as I was doing. That's a sometimes fun, sometimes dangerous approach. Thankfully I had the help great lab technicians and researchers who had already been in the trenches and could walk me through the important research procedures.

My project studies the symbiosis between soil bacteria and plants - specifically rhizobia and legumes (Fabaceae family). Rhizobia enter the roots of legumes and grow inside plant tissue that forms what are referred to as "nodules". Plants provide food (sugar) to the rhizobia while the rhizobia provide nutrition (nitrogen) to the plants. Most of the time rhizobia are already present in the soil, but sometimes the soil is inoculated with rhizobia to improve the chances of nodule formation.

It seems simple at first, but as I read more about nodulation, I learned that it is anything but that. I used to read about nodulation in my undergraduate studies and think about it at a macrobiology scale. My current research, however, is focused on nodulation from a microbiology scale. It is an interesting switch in perspective that has made me gain more of an interest in microbiology. When I really think about it, people don't truly understand things until they are able to break them down into their simplest components, and my current focus on microbiology has certainly been enlightening.

On one hand I am reading things about applications of nodulation as it applies to agriculture and on the other hand I am reading about microbial metabolism and genetics. Over the past 50 years agriculture has gained more of a focus on genetics and microbiology and I feel that current rhizobia research is going in that direction. Just as some researchers were able to apply microbiology to make breakthroughs in plant resistance and growth, I think a breakthrough in rhizobia research could help improve soil fertility - at least in a way that is more natural than dumping chemicals all over it.

This is generally the point where people get distracted by other things so before you go you should know that I am done with the first stage of my research. I am specifically looking at competition between individual rhizobia strains for nodulation of Hairy Vetch. That is, if such competition exists. For all I know the nodulation could be a first-come-first-served occurrence. I won't know much until I actually begin the analysis. Now I see first-hand why news stories about scientific research can say one thing one month and something different the next month. Research results can be fickle even if you are doing things properly.

2013/11/04 - Entering the growth chamber

One week in the growth chamber
Thanks to Mary I was able to use these adorable mini-trellises to support the plants.

A few weeks in the chamber. Thankfully all the units contained a growing plant

Last day in the growth chamber was 2013/12/18. Some visible variation, but not enough to make reliable predictions.

Non-inoculated control - Inoculated treatment - Nitrogen enhanced

Some plants have 50 nodules. Some have Over 150. It depends on what kind of mood they were in.

That's it for now. The next step is heavily focused on molecular biology. I will likely be bothering the other lab researchers as much as possible to make sure I get things right.

A typical fun day

Mary started her day with lab inventory and found this old piece of equipment that came with the lab way before we moved in. It is now looks perfect to be used as a home of cute little flowers.

I saw it again in my office.
I guess Natalie came up with some cool ideas for it.

We're so excited to receive some TaqPolymerase samples but didn't think that they would be this generous!!

Dry ice came with the package is always fun.


I think December is the best month of the year to celebrate birthdays.
This time we gathered to wish for Payton.
Happy birthday!!!

End in Sight

Friday was JiJY’s birthday!  We managed to surprise her by celebrating a day early, and Sarah even made awesome pink cupcakes.  

I always associate the end of fall semester with festivities, and between Thanksgiving, a few lab birthdays, and winter break coming up, it definitely seems like it’s time.  This week is finals, so we’re almost there!  And while winter break may be a chance for some students to give their brains a vacation for a while, most of us in the Grossman Lab will probably be scurrying around with time to finally dedicate solely to research.  Lots of new projects are coming along, and this will be a great time to give them more attention.  Good luck on finals!
