Thanks Alexander.  I'm glad you enjoyed the post.

Yes, this is our first season with the wheat crop.  Actually we have been working with the farmer and his wheat crop through this season's life cycle to "prove out" the technology and the NDVI imaging.  I and the farm owner, Ronald, reviewed the NDVI composite image from the 3/24 survey and I was pleased that he explained each area that showed no growth (black to grey).  Back in October, he had sheared off the top soil in some lower areas and moved it up to higher ground.  He had also cut some irrigation paths.  The wheat that was planted in these areas with no good soil or nutrients, showed bad growth.  You can see in the 4/24 NDVI how after the nitrogen application got into the soil that the total area looks healthy.  We are both excited that the technology is proving out.

As for disease, as the wheat matures, we hope to be able to spot any areas affected by below average growth (indicated by the NDVI color indexing).

Once we trust the technology, we will be using it on Ronald's big money making crop, tobacco...  which he is preparing to plant in two weeks.  I'm not a farmer, but am excited about learning so much with Ronald as we start with the Tobacco acreage.  He said that because of the nature of the Tobacco pricing, yield, and its lifecycle that any indication of a poor area in his fields that the NDVI imaging give him early notice, he would take action to remedy even a small area.

I hope that are we begin the surveys over his tobacco crop next month that we can demonstrate some value to Ronald and the rest of his many farmer friends in our area.

I would welcome any feedback you may have or learn about using other sensors, etc. to spot diseases in crops, other than using the NDVI processed images.

By the way, we also have a FLIR thermal camera that we may survey with to maybe indicated irrigation issues, etc.  When we do so, I'll post any good results.

Hope this might help you.

Thanks for your interest,

Mike G.
