pathetic veg growth in California
Comments (1)This may not be a fair comparison, because I am Ca. coastal, which hasn't had much hail - but yes a lot of rain, fog and very cool - for June - weather. However, I had a very good early crop of cool weather crops, broccoli, lettuce, bok choy - (so vigorous - fed most to chickens), snow peas, garlic, leeks, and onions - and the limes and citrus very nice. My boysenberries, apricots, plums were super, and I am trying to find new ways to preserve them. My newly planted low-chill apples are also producing. However - the tomatoes look very sad. They have some fruit, but the plants are sad. Peppers just now beginning to show some growth - I really can't complain, except to say that I can now see what REAL rain can do, and I'm loath to have to return to irrigating my garden - but with our USUALLY dry climate, I am sure it won't last forever. On the other hand, I decided to go with the usual cool weather that June and July gives us near the ocean, and have planted more lettuce - and am expecting to get more of that cool weather crop. Might just as well enjoy and go with nature on this topic. The nut trees, persimmon, fig and banana trees are not doing all that well, but I'll accept my good fortune - and a whole lot of weeds still left over from all that rain. It is nice that we are now off water rationing, but I dream of having normal rain fall here in an otherwise arid country. Can't win em all - Just my 2 c's. Bejay...See Morewinter sulstice
Comments (19)I too watch the solstices and the equinoxes, but can't really say that I associate nudity with any of them. (Then again, I don't associate bathing suits with hot tubs.) And from the evidence in Ireland, Egypt, China and the Americas (as well as many other places), noting these events has occupied a lot of time and energy from the earliest humans. Besides the example noted, places like Machu Pichu, Stonehenge and some Anasazi creations also have light phenomena associated with them. Even the pyramids at Giza show alignment to celestial happenings. (The pyrmids were cued to the rising of Sirius, about the same time as the flooding of the Nile). The time of the solstice also occurs near the time of aphelion (earth closest to the sun). This changes on a geological timescale, so our distant ancestors knew the time of the summer solstice (when we are now farthers from the sun) during really hot summers when the Earth was closer to the solar mass. Another aside, the precession of the Earth's axis, coupled with the Sun's path through the galaxy has "moved" some of the constellations. The chance alignment of the Big Dipper will be gone in 500 generations since those stars are not all close together. (The cavemen also had no dipper in the sky 10,000yrs ago.) Because of the Sun's own tilt, the Earth's precession and the passage of time, the constellations in the Zodiac do not match the calendar. There are some constellations that are almost out of the plane of the ecliptic, and some that are not included. That means that for Taurus, for instance, 30% of the time the astrologers say that we are in the House of Taurus (mid-Apr to mid-May), we are not. Also, how do you chart somebody who is born in the House of Pegasus? This is just another proof (as if any were needed) that the whole Astrology thing is bs. Also, in a similar so-what vein, the extra second we are adding to the calendar is not added to the GPS (Global Positioning Satellite) base. Since this system was arrived at in the early 80's, the capacity of adding an extra second was not built in. For GPS, adding time means that every calculation has to be re-done, something they don't do. A watch set to GPS time is now seriously out of whack, something like 5 or more seconds off. One more whacky thing that comes to mind as I write, did anybody else catch the drift of the North Magnetic Pole? Although it tends to wander some (reversing sometimes too), this year it took a giant step westward. For the part of the world below the high numbered latitudes, it doesn't add much to the already off-true-north point of our compasses. But how would you like to be on Baffin Is. when you compass is off by 10° more than last year!...See MoreDesigning automatic irrigation software...
Comments (6)"How should I adjust the watering time based on the date? " You can't adjust watering time simply by the date at least I can't see how it could be done and still be accurate. The amount of daylight alone IS NOT a good indicator of ET and subsequent watering times. The "Factor" you are searching for is calculated from information you are leaving out such as temperature .. humidity .. and WIND?? .. in addition to the days solar input that your are working with that by the way can be modified significantly by cloud cover. .. if you want to develope an accurate software then the user must input the basic and current weather data each week. ( temperature .. humidity .. WIND ?? .. and solar radition as modified by cloud cover ). The good news is the equations you are looking for are already in the library and have been developed by some very good scientist / engineers. Just plug them in to the computer and you can calculate a theoretical ET for a period of time and a given set of weather data. Then each user then needs to divide this theoretical ET by the actual ET for any given day or period to establish an error from the theoretical ET .. a cofficient sometimes refered to as a "crop" coefficient. Once this coefficient is determined the software's calculated or theoretical ET determined for any set of weather conditions can be modified easily to give the actual ET for a given period of time ( a day week ect..) ET ( Actaul ) = Kc x ET ( Theoretical ) This ofcourse can all be converted to run times given that you know your systems percipatation rate BUT keep in mind how much time you need to water is not directly related to actaul ET. The uniformity of the irrigation system as well as soil conditions and other factors will affect final run times. Good Day ......See MoreSummer Solstice--Take your shade pictures
Comments (3)I started to map my shady areas this morning but couldn't maintain focus. I know the shade pattern has changed over the years since my first shade study in 2006 but since everything is going gangbusters, I'm guessing the plants don't really care/have adapted themselves to their growing conditions. I did plant some winter sown Dianthus, dig out & pot up a handful of volunteer Virginia knotweed seedlings....See More- 6 years ago
