About drip watering:
I use drip irrigation on my pumpkins as well as many other fruit and
vegetable crops. It works well for me, the placement is good, and you get
precise control of whats going on.
About lots of water and breathing probes:
Every soil has a different texture and structure, and like wise can hold a
different amount of water. A sandy soil will hold comparatively less water
per inch of soil than a heavy clay....this is common sense, but they key to
moisture manangement with plants is how full the soil is relative to what
it can hold. Most plant roots do not like completely saturated soils, the
roots have to have ample air to "breath". It has been shown and
scientifically proven that the optimum moisture level in the soil is 67% of
field capacity. Field capacity is the amount of water in the soil after
gravity has drained out the extra moisture. For example if a sponge is
soaked in a bucket of water then held above in the air, a fair amount of
water would drip out, then it would hold the rest. Once the sponge stops
dripping and holds the moisture in it that would be equivalent to field
capacity. Optimum plant health is at 67% of this field capacity. You
should water when your soil moisture gets dryer than 67% and stop watering
once you are wetter than 67%.
Research grants for AGS.....that sounds great there sure is a lot of
uncovered ground.
