#36 is looking great. I think we could do something with the letters though to give a new feel to it. I like the graphic in the background that looks like the sun. I think the triangles could look better though. A gold triangle represents the fruit of the tree which is how we make our money so we like the gold triangle.
#40 #41 #42 #43 have solid tree areas which is an interesting idea. That could be something that works for us.
I like some of the word art that was done on some of the others but none of those were the right fit.
A few ideas:
in agriculture, what makes a plant grow is the sun,water, and soil. It would be interesting to see some ideas of how to incorporate at least sun and water (#36 gave a good start). I'm not sure if brown soil would be easy to represent, nor am I sure if it would look good.
The lettering or word art could still be somewhat traditional and conservative, but also new, refreshing, modern, etc.
The triangles in our current logo have very distinct edges and corners giving the whole logo somewhat of a blocked shape. It would be interesting to see some change there.
