Innovative Analytical Water & Soil Methods
Southern California desert
January 2022 Site: Golf Courses Scenarios: Water Sample, Bac T sample, Soil samples of good and bad turf conditions
Comparing available soil nutrients by both conventional methods and a new Legacy Method Comparing exchangeable soil nutrients by conventional methods to Totally Digestible by the Legacy Method
Shocking, stunning, game changing results, found industry chronic.
HCT WaterSOLV products have been on the site about 4 months. The soils were so compacted you could barely put a spade shovel 1/4 of an inch into the soils. We are not reporting the pre-treatment conditions as it is not the intent to show progress. The intent is to exhibit both good turf soil conditions as visualized on the vast majority of the course(s) under soil conditions that are horrendous. The intent is to also show the comparisons between good turf and horrible soils and bad turf and horrible soils.
We also exhibit the differences in the soil data of available nutrition across two soluble pastes extract methods, then the differences in the data of soil exchangeables between existing lab methods of AA/DTPA, Mehlich III and HCT's Legacy Method (Total Digestion). All with the intent to show how conventional methods do not convey realistic conditions, and where enhanced Legacy Methods provide a shockingly greater degree of data accuracy that exhibits the deterioration of our soils and vegetation from nutritional and biological saturations, of which can be reversed and corrected at and for gain in lower costs, higher efficiencies, product grade and yields. Conventional agronomy methods are difficult to sustain economically, until now.
Available Nutrition: It would be our summary that the more realistic the extract used in the lab to represent the site specific water chemistry, the more accuracy can be realized to actual nutritional availability. That also, an increased ratio of the extract in water over 1:1, be greater, in the form of 3:1, as done in many regions of the world, to depict more accurate conditions. That the chemical retention time should be more representative for the total chemical reactions, which may be better represented at 72 hours, not less.
Total Digestion vs Exchangeables
When we view our soils as a host to vegetation, to provide hydration, oxygen and nutrition, the soils require pore space, CEC and SAR. By not knowing the saturations of accumulated salts, whether nutritional or toxic, biofilms or biotoxicity, these accumulations can hinder the essentials and even compile toxicity. By knowing the saturations, remediating their saturations, restoring the soil's porosity, infiltration rate, and meeting vegetation's essential needs, we create vitality as well as nutritional and water use efficiency while enhancing the quality and productivity of vegetation.
Of dozens of soils we have assessed across the country in turf, landscape, agriculture, residential, the accumulations of nutrients, namely calcium iron and aluminum as well have been more than excessive and extreme and identified as the culprits hindering the essential needs of vegetation.
