I wanted to write and let you know that you may want to visit the new blog over at http://www.c.Optmzr.co
Although Blogger helped me prove a point to a co-worker, it doesn't have the depth and sophistication to support multiple authors and a richer long term experience. As such, I invite you to cruise over there and check it out.
I'm not going to "kill" this blog, but my contributions will be less often here. Over there, we hope to post multiple times per week and create a rich environment for others to contribute as well.
Cheers! and thanks for reading!

Indiana's Conservation Consulting Initiative
Indiana farmers lead agriculture in so many fascinating ways... notill, precision ag and cover crops. Certainly other states in the US have massive acreage of each of these but it appears to me that Indiana has an amazing foundation for these practices to gain deeper and wider adoption faster.
First, Indiana has good but not great soil and weather. I joked with several Illinois and Iowa customers this summer, that Indiana would fare well with the extra rainfall... we have small valleys! Between these small valley's we have lots of clay, timber soils as well as sands, depending on the area of the state. Rolling terrain increases erosion but also sparks creativity around reduced tillage and cover crops.
While this terrain varies, we are also fortunate to receive ample rainfall. Different than some of our western counterparts or even far eastern farmer friends, we tend to get ample rainfall to capitalize on soil health management. (I would argue that the more severe the climate the more response you get from soil health management but that's another topic.) Anyways, rain makes grain and thus, well managed clays can quietly yield 200+ bushels per acre and cost far less to purchase or rent, again accelerating creativity.
Finally, this variability, yield potential and field size, afford the Indiana farmer technology investments and experimentation that outpaces other areas with less variability and scale. No doubt, an Illinois or Iowa farmer can achieve massive scale, but the variability within their fields has struggled to justify the on-farm experimentation behind precision ag thinking.
This all adds up to some exciting people making a real difference around the globe. I'm proud that Advanced Ag Solutions is among the approved mentors for CCSI. http://ccsin.iaswcd.org/
Next week we share some of what we've learned with the "hub farmers" who are doing on-farm research around the state. I'm sure they'll have some great roundtable discussions!

Audio Interview about Optimizer 2.0
A former college intern stopped by the office this morning to interview me for his sales class. He asked if he could record it. I said sure. After he left, I happened to think "that'd be fun to publish." So, here it is!

Everyone Wants One Device
At a recent dinner meeting a CEO of a prominent company was saying how everyone wants a single software package that consolidates
all their activities. He said this is true in agriculture the same as it is other places. He told a
story of carrying a PDA and phone and how he wished they were one in the
same. I remember those days and thoughts
myself quite clearly. Everyone told me I
was crazy... first for carrying the Palm Pilot and secondly for thinking people
would like such a combined device.
Ironically, it was pointed out that he was carrying two
smartphones now... or should I say, had two smartphones sitting on the dining
table of the restaurant. He laughed and
went on to talk about tablets and laptops and how at one point he had so many
devices he couldn't fit them in a single briefcase.
I didn't want to write a blog post about devices
however. What I wanted to reflect on was
the desire of people to use technology to consolidate, streamline and simplify
their lives. This is a noble ideal,
however, almost every disruptive technological wave is wrought with desire to do something that was either a) not capable before or b) totally new way of doing what was done before. Example... now that you've got a wireless connection on your PDA, what type
of programs can you build now? It's
revolutionary stuff.
Combining devices or software is a bode to creative
intellect and ambitious visionaries. The
trouble with this however is the new device or software is much like the main
character in a Shakespearean tragedy. He
suffers from an undeniable ending...
whereby that which defines you, destroys you. In some modern movies the same rings
true. We love these stories because we
see it coming but can't stop it. It
relates to our lives in a very personal and frightening way.
In precision ag and modern farming I often hear requests
for a single display in the tractor cab.
Or, perhaps a single software that would manage both their financials,
their grain marketing and their variable rate precision ag files. There have been a few programs that strived
relentlessly to obtain this nirvana.
However, they just never quite have "enough" features... and
ultimately the feature creep in trying to obtain this vision ultimately kills them.
Instead of bemoaning the
hopelessness of our state, I believe we can learn from other
industries. How is it that Google, Apple
and Microsoft can all share calendar apps and yet compete with each other? They use API's issued by their
competitors. The original goliath builds
an API so that smaller innovators can build on their foundational
technology. But in so doing, they open
up gates to giant competitors in other industry segments. Why
would they do this? Because it is
ultimately in their best interest to do what they do best and provide
opportunity for customers to start swimming in their pool, regardless of what
device or software platform is currently the customer's favorite.
For precision ag to "go mainstream" at the farm
level, we need both goliaths and startups cross-referencing each other's
API's. In so doing farmers themeselves
can stitch together systems that work well for themselves and access the best
features of each... and do so fairly easily. Sure there will always be problems to solve but this simply creates opportunities for new
innovators to step in and fill those new gaps.
Who is in the best position to promote this culture? Software purist companies. They have no incentive to move product
through their software, but instead must move their software for the sake of
the software's value in and of itself.
With that said, it probably is NOT going to be a software company that
aimed at being all inclusive themselves.
I'm personally on the look out for software companies that want to do one thing
really, exceptionally well and are open to playing well with others. Those fine companies will reach more users
faster, and deliver greater value propositions versus their price.
Here is another way to think about this "one device" desire... we already have just one device! Our own brain and body. We stitch together various technology and hardware to accomplish our goals at the appropriate value. I urge you to look for components that talk to others as a core requirement.

Ultra High Yield Soybeans
I've written a lot about precision management of corn lately, so I figured I'd give soybeans a nod of the hand. Here are the building blocks to insanely high soybean yields.
1. Start with good soil. If you haven't got any then improve it.
2. Rotate with other crops. Multiple years of corn, then cereal rye cover crop.
3. Plant early. Yield potential is established AFTER you plant and you need flowering sites.
4. Time fertility for ~20# soil nitrates prior to V3. This can be from variety of sources... no more, no less.
4. Plant very long season variety. Again, more flowering sites increase max potential.
5. Adjust population to expected lodging and shade. Tall beans never yield.
A) Lower populations where soil nitrogen is expected to be higher than desired early.
B) Lower populations in wider rows for less plant to plant competition.
C) Lower populations with longer maturity (they'll make it up)
6. No weeds allowed. Spray early and often.
6. Track soil moisture and only augment late if possible. No irrigation? Pray for rain.
7. If you have soil moisture late, top dress with N at beginning of seed fill to meet yield goals.
8. Treat pests and disease according to scouting.
9. Consider desiccant for harvest aid.
10. Harvest timely and with proper settings.
11. Sow cover crop to soak extra high N load from vibrant plants.
This is over simplified and highly opinionated. It's also proven with experience on about a zillion field observations and various trials. I left out some things that should be obvious, and also some details about things that will make this all automatic. We're working on software that will help. In the mean time, this should guide you.
The key to high yielding soybeans is having an environment that is rich for the plant's needs at each time of its life cycle. There are two primary stages. Vegetative and Reproductive. They overlap from flowering until the end of new leaf development. You want to maximize the nodes and thus flowering sites per acre based on your environment. This changes across the field and throughout your planting window. You need to adjust according to these things! Furthermore, you should augment your available nitrates to stimulate bacteria to get to work early (a little N boosts leaf surface and juices the roots for faster and greater nodulation.) But, you don't want too much N early as the bacteria get lazy. This might mean reducing your tillage and growing a high C:N cover to soak and tie up N early. Sounds funny to suggest augmenting N levels to DECREASE nitrogen levels but it's truly important. In fact, studies show too much N early can delay N fixing and ultimately crush yields. Be careful.
Once healthy, evenly spaced plants have taken off in a nitrogen balanced environment, your job is to protect them so they can develop an insanely high number of flowering sites. This means protecting their water source (soil), root development (compaction), and leaf surface (insect and disease.) With crop rotation most of that is taken care of free of charge. The planter becomes increasingly valuable as your populations become lower. You cannot skimp here. Try treating them with same affection as corn... seriously, try it. Some people are known to time their row units so they drop equally spaced soybean seeds... and raise 160+ bpa records.
Ultra long season varieties have longer vegetative periods. In fact, we have proven that the day length sensitive talk is bogus. That's right... it's garbage. Instead, focus on GDD heat units prior to flowering. After flowering the soybean marches to maturity based on the fact that there is a night and not necessarily the length of the night (can anyone say, street lamp green beans?) So, the plant sees the light switch, takes a nap and then wakes up to grab sunlight again. You should focus on selecting a variety that will march to maturity close to or even after anticipated frost given your planting date and temperature outlook. (obviously, you don't want to harvest every field after frost, but this post is talking about ultra high yield, okay!)
Soybeans grow like a cube. Their geometry is much different than corn (a cylinder). They will canopy at about the same height as their row width. This isn't exact but it's a decent rule of thumb. Given their ability to add flowering sites at an exponential rate, your exact population is highly influenced by your row width, planting date and maturity. What is the best row width? Tell me your planting date, seed variety and soil properties and I'll have an opinion.
As your tree-like soybeans sprawl out with tons of flowers and massive nodules on their roots, you'll want to know what your soil moisture profile looks like late in the season. You should have well over 100 bushel potential based on node count per plant. As such, you'll need to feed the seeds developing in all these pods! History shows that good bean years favor dry early and wet late with good soil N mineralization happening late. Soybeans require around 5# per bushel of N and can produce 60-70% from atmosphere. This means that if your soil contributes 80# (3.5% OM soil) your cover crop releases some late and you want more than 100 bpa, you're going to need an additional 50-80# N top dressed. How do you apply it and what source? That's up to you but do as little crop damage as possible and get it into the root profile. Foliars are not going to be enough.
For most of my midwest farmer buddies, the idea of spraying soybeans in October with a descecant sounds crazy. I might get made fun of... but this won't be the last. The truth is, a crazy lush, full season soybean plant is going to want to hang on and keep pumping late into the fall. It really doesn't care that you have empty grain bins. It wants more and more seed and will push the plant right up until you or mother nature say stop. That's totally okay given your yield goals and investment here. I can't advise trying this on every acre but with some experience you could probably uncover a means to justify harvesting 90+ bpa soybeans in October after a sprayer trip.
Oh, and I should run a budget on this... I'm pretty sure that seed rate adjustments could cover late N application costs (besides deferring rate decision until knowing exactly what soil moisture looked like.)
So that's it. My nod to our poor secondary crop. I love chatting about plant growth so drop a comment below. There's so much I left out that others have tried with good success. This is just my preferred crop plan for high yields. What is yours?

Why Notill Farmers Dig Precision Ag
I've been running a precision ag crop consulting and software company since 2006. Prior to that I farmed full time. Fortunate for me, my father and I practiced notill farming and utilized yield monitors and variable rate technology. For me, it was normal... but since then, I've learned that the two practices go hand in hand. Now, I'm fortunate to work with several of the best in class for both of these practices. Here are my top reasons as to why these practices tend to converge.
1. Early adoption... Both practices are relatively new in the whole scheme of farming. Leaders make decisions that result in change and these leaders are moving early.
2. Management... let's face it, full width tillage is easier... and so is doing what you did last year. Both notill and precision ag require more management. Some say they adopt one or the other just for the challenge, while others say profit motivates them. I would agree with Farm Futures survey (need to get link) that shows highest profit farmers practice and enjoy both ...and reap the profit reward for their management.
3. Speed... High profit farms tend to get more bushels in less time... both labor and machinery. This is accelerated by both techniques and multiplied when used together.
4. Timing... Time is money, and timing is priceless. Notill and cover crops emphasize timing field operations with natural environment. Alongside this is data quest to understand what is working, both NOW (in field sensor), and what happen prior (yield monitor and rate trials.)
I firmly believe the most important element to farm profitability is timing. Making hay when the sun shines is about leveraging your brain and brawn to lower risks and increase rewards. It costs almost nothing to do it at the right time versus the wrong time... and with advances in notill machinery and precision technology the cropping system as a whole is more "forgiving" on timing. What do I mean by that? A well managed notill field can support machinery traffic before tillage can be performed and then the system loses less moisture to the atmosphere and soil to erosion all while increasing equipment speed per acre... and decreasing time spent per acre. This all adds up to better timing by the farmer.
This is by no means comprehensive but were just a few things on my mind this evening. (plus, I was due for a blog post... my timing was getting behind!)
Cheers and thanks to my readers for following!

Building Rx while in the Field
I'm pretty pumped that planting is underway in Indiana. Since I can't resist sharing ideas on this blog, I thought I'd throw one out there for you all to chew on. Share it! (links are embedded so you could make it work while you are planting if so inclined!)
I’m
going to field now to test it on a 20/20.
(UPDATE: Well, the farmer was kind enough to spend three minutes and go through steps with me... the trouble is the FieldView app does not allow you to pick from the DropBox folder. I grabbed my Chromebook, connected to my iPhone hotspot and downloaded zip files. The grower then logged into his FieldView app and we uploaded the zip folder without extracting... then, synced his iPad and "bam" he had it on his 20/20. Very slick... but not yet totally doable via iPad only. Please comment if we missed something!)
I just used my iPhone to create a VR Seed map in Optmzr,
download, extract and post to Dropbox! What does this mean?
If a farmer has an iPad connected to a 20/20 they can create and
get fresh Rx while in the field. (not quite yet... see below for UPDATE.) Here is how:
2. Select
“Open With…”
3. Extract
contents into a new folder using iZip app.
4. With
iZip still open, navigate to files you want to send to Dropbox, ignoring
Nitrogen files, or vice versa with seed depending on what you are doing. (Optmzr downloads all VR applications to that field every time since they can change with the weather.)
a. Highlight
appropriate files (need .shp, .dbf and .shx)
b. Select
“Send” from iZip app and chose Dropbox as the destination (install Dropbox app on iPad if haven’t already.)
c. Select
desired folder to place files in.
5. Files
appear in DropBox.
With this complete you may “Share” the folder to customer
(or use your own FieldView if you’re a farmer) and download files to your
iPad and port rates files into your 20/20 per FieldView steps.
All of this can be done with the iPad while in the field if
you have an internet connection. And, the shapefiles are small so they move easy.
