ON the days that I do not travel this summer, I will post a nutrient of the day. Todays nutrient is water. Water, sunlight and carbon dioxide are needed for basic photosynthesis. The only one we can do anything about is water, although in the midwest we rely on what nature provides in rainfall for the most part. Too much water cuts off growth and nutrient uptake. Too little water kills the plant. In those years when we produce record yield, rainfall amounts and timeliness are usually just what we need. Timeliness can be as important as amount. I could ramble a long time about water, but you get the idea. Even though we have moisture at uptake depth even in dry areas. We need some rain in some of those areas to boost plant growth so that the crop can get to the moisture.
