In western NE with light sandy loam soils, we average 15 inches of precipitation a year with a very wet year being 20 inches. In Indiana for example, this likely would be considered a disastrous drought.
Is there information out there that gives a "recommended/minimum" precipitation for plant types. It would be nice to look at a quick reference and see what kale, Winfred brassica, Egyptian wheat, milo, soybeans, corn, radishes, turnips, millet, canola, etc. need for minimum/adequate growth so one does not waste a year (or more) trying different plantings. Is there more scientific information out there instead of this plant is "more drought resistant? The local COOPs have expertise with corn, soybeans, wheat and milo; however, I get blank stares when I mention nontraditional plants.
Lets assume soil test, proper fertilizing/liming, field preparation, and other farming stewardship is completed.
Using only precipitation (or lack thereof) requirements as your guide, what is your a top 5 list of plants for year round deer nutrition with only 15 inches of precipitation?
Better said than I. What does well with an expected rain fall of 15 inches...
The same thing can happen if you get too much rain and delay planting. You might have the same rainfall, but it isn't at the right time.
I am aware of a "movement" toward no till planting. I do not see me getting a no till drill.
I am learning about hardpan and soil compaction. I do not know if that is a big issue for me based on my soil. Anyway,....small burnet is the only crop I know of that can grow with less than 15" of rain. Chicory may be a good choice to plant with it because of the taproot. Small burnett is not recommended to be planted in a monoculture.
