August 30, 2017 - Quiz #99

Folks, 

We're going to put an end to CT Crop Quiz #99 right now due in part to the flurry of comments, concerns and wrong answers that came in, - everything from “This quiz is too hard,” to “You're too tightfisted with the $100 awards.” So to end this one now, - which I said was a bit of a weird one anyway, - here are the answers to the quiz questions. We'll need to wait for quiz #100 for a possible winner, I guess.

Folks,

OK. We've got a bit of a weird one here today in CT Crop Quiz #99.

Everyone by now knows the rules. Be the first to answer the following questions correctly and you'll receive our Workgroup's legendary $100 cash award at an upcoming event. Any CASI members directly associated with this quiz photo or any of their family members are not eligible to take part in the quiz process and will be disqualified from consideration.

What form of CT is shown in the attached photo?

An odd one here maybe. Following an early-season corn silage harvest, it was a one-pass harrowing tool and then a corn planter going right back over the planting beds and corn stubble line to establish the double corn crop. So, technically, - the spouse of the farmer who did this told me that they ‘clawed' the sparse residue from the first corn crop with a spike-toothed harrow to just loosen up the surface soil a bit, and then planted right into the first corn crop's stubble.

 

What is the CT-planted crop shown in this photo?

corn

 

How was this CT crop actually established? (What specific operation(s) were used?)

Following a harrow operation to loosen up the soil surface, the second corn crop was planted into existing corn lines and beds

 

Name the nearest US town to where this CT crop photo was taken.

Kingsburg, CA

 

What is the nearest street intersection adjacent to the field where this photo was taken?

SE corner of Mendocino Avenue and Kamm Avenue

 

Using the old definition for “CT,” would this field even be considered “CT?”

No. There is not much surface residue at all in this field. It therefore wouldn't conform to the old definition for “CT” that talked about the need for > 30% surface residue after planting time. In fact, it was pointed out to us by longstanding good colleague and CASI supporter, Don Reicosky, that we out to move forward and update ourselves with these “CT Crop Quizzes” a bit and not hang onto the outdated and confusing “CT” terminology. Please see Don's suggested reading that is attached. – I fully agree and henceforth, we'll move forward with the broader term, “conservation agriculture.” But this field and these photos are still then not a true representation of CA, as we know.

 

All the best,

Jeff
