• 290,000+ gallons of leachate treated

Lower Power House phyto installation has continued a stellar performance for the third year in a row. Precipitation abounded this year and caused lesser use of leachate. However; that allowed us less use of fresh water irrigation mixing procedures for drier weather. (Only 40,000 US gallons). We came very close to using three hundred thousand US gallons of leachate this summer as opposed to two hundred thousand US gallons in last year’s dry weather and much smaller trees. The growth rates are normal to perhaps slightly less than an optimum average. But there exists on this site a very healthy plantation of five varieties of hybrid poplars. This is partly obvious in common leaf sizes at 13 inches wide X 15 inches in length. Analysis of culture samples show affirmative results. Mid season soil sampling displayed healthy growing conditions. Tree growth rate performance will be in electronic form in due course.
This year has re-affirmed the cause of need to operate leachate application manually. Rainfall must be dealt with or monitored as does daily weather conditions regarding both types of watering procedure. Secondly, a sudden serious change in leachate conditions would be noticed by manual daily testing. (Pond color and conditions change.) Some days H2S gas is noticeable necessitating lower pressure rates for irrigation. Irrigation equipment must be kept free of weeds to maintain visibility of operation. Roto-tilling, (aeration), is also a requirement as is shown in certain tree’s ability to use up all leachate chemicals. (see conductivity and PH charts.) (Also see soil test results.)
