Yep, the spot where I have been dumping my slurry in the yard is growing like crazy at all. The grass and weeds are going crazy! No surprise richardh. Plants grow better along dusty gravel roads too. Vehicles shed rock dust assisting plant health. Granite dust. Finely crushed lime. Plants love that stuff.

This very much interests me. I would have tried these experiments myself, and will still do this with some veggie plants this year.

Was any of that slurry made with AO?

Was any of that slurry made with AO? There is naturally a lot of AO in the clay here, and I use a lot of red clay when coarse tumbling. But very little AO grit was added, about all SiC from coarse grind. The 4 pots with white kaolin is like 35% AO naturally. But it is a very sterile clay and not very good for growing plants. The kaolin mines here hardly grow weeds or plants.

It has been known that rock powders improve soil for better plant growth. I recall an author wondering how long it would be until folks fertilized their maple sugar bush trees with rock powders.
My great wonder is what mechanical or chemical action/reaction fixes the nitrogen in the medium.

My great wonder is what mechanical or chemical action/reaction fixes the nitrogen in the medium. Those pots have a tablespoon of well balanced time release fertilizer in the bottom of the pot. Once the roots reach the bottom of the pot they will start to feed on needed nutrients as the plant demands it. I doubt that the slurry will feed the plant nitrogen once it starts to get bigger. Rock dust may supply P and K, but not N. However, the roots reached the bottom of the pot much faster in the slurry(roots coming out of bottom of pot, not shown), therefore getting the supplemented fertilizer faster. Fertilizer is fancy expensive grade with micronutrients, note days of time released relative to temperature in upper right corner(180 days @ 70F): A moron can grow beautiful plants with Florikan.

Thanks.
I have heard a late snowfall, a lifetime accomplishment for some areas of the country, fixes N. I wondered where it came from. The N, I know a thing or two about snow.

Looks like the slurry is overdosing the plants as they get older. Root development accelerated. Leaves getting distorted. Overall stem growth is overly massive. Accentuated veins in leaves is often a sign of poison. Can be other causes. Suspicious of excess nutrient. Slurry on right. Root development better w/slurry. Stalks thicker. Slurry on right, occasional leaf distortion. 6 pots of slurry on left front corner, note curly growth. Plants in slurry blooming earlier and at a higher rate.

The slurry pots were pure slurry? Not looking so good now, but i'm assuming at lower concentrations the SiC wouldn't have such a profound effect.
I'm filtering all my mud through sand and charcoal but i still feel uneasy about potential soil contamination. Probably crazy, especially since i live 2 blocks from an oil refinery that often makes the air intolerable to breathe and has occasionally painted my yard white with fallout. It still niggles me.

I'd be interested to see the fine root development too. Given the nutrient uptake is from roots feeding on minerals abstracted from coarse-crumb soil, it makes sense that they find this easier from fines. I would expect fine root division if the plant finds the slurry is sharp on a microscopic scale. Or is it so fine that this is not the case?

tims metalsmithThere is a lot of variables at play here. Yes Tim, that is pure slurry from the rotary with no Borax. Keep in mind there is time release fertilizer in the bottom of all these pots. The sterile red clay has a time delay in that the roots have to travel to the bottom of the pot to reach the added fertilizer. The nutrients in slurry may have assisted the growing rate to the bottom of the pot. Allowing plant to reach supplemented fertilizer quicker. I have faster reach times with shallow pots verses deep pots. 4 inch tall pots verses 6 inch deep pots, makes a lot of difference. Often it is a waste of time to ask questions/theorize. You simply get better results by using X soil mix verses Y soil mix. The 'why's' are often never understood. i can say with 100% certainty that the slurry is having an impact. A chart showing some basic nutrients in any soil. The witch's brew in a tumbler full of mixed rocks washed down the Rio Grande from 100 different sources ? No telling what kind of chemical smorgasbord is mixed in this slurry. Basic nutrients, emphasis basic. Note the last 6 nutrients are metals(maybe not Boron). Many of the same metals that create the colors in our rocks. Green rocks probably have copper for instance. Iron makes a plethora of colors etc, Too much of some of those metals is dead poisonous like copper,Boron and Zinc, others. Example - Boron: I don't think anyone has ever considered Boron dust(tourmaline is high in Boron) when cutting cabs on this forum for instance. Boron is toxic for real. If it does this to plants you can rest assured it has an effect on mammalians. Article on Borax, included is relationship to geology www.plantstress.com/articles/toxicity_i/Boron.pdfThe article says that the only way to reduce Boron in soil is: 1) Dilute it 2) Grow plants that metabolize Boron in said soil. Overly excessive Boron in soil is basically polluted/poisoned soil. And the most common source of excess Boron is well/irrigation water. Just saying, a mixed batch of rocks in a tumbler would create a slurry that would challenge the most brilliant chemist. If a load of rocks is creating gas in your barrel, laugh and do not bother trying to figure out why. The answer is probably beyond the scope of us average Mo's. Excepting glass, we know why it creates gas in the tumbler.

Plants got sold. The distortion was not enough to make too much difference.
Conclusion was advanced growth and big strong plants. They seemed stable and had foliage displaying rich micro-nutrients. Concluding that an excess of micro-nutrients were present in the slurry. Once the plants toughened up and became adults they processed the smorgasbord of chemicals and metals just fine.
Results did not surprise. I had been dumping slurry on the floor of the greenhouse for years and had seeds germinate in it. Seeds with hard shells that would not germinate in sweet soils. The slurry seemed to act as a shell softener and still not burn the roots at germination. Hard shell seeds that needed treatment in hormonal chemicals:
EFFECT OF SOAKING PERIODS , GIBBERELLIC ACID , AND BENZYLADENINE ON PISTACHIO SEEDS GERMINATION AND SUBSEQUENT SEEDLING GROWTH (Pistacia vera L.) Nabil M. Ameen A. Al-Imam Dept. Hort., College of Agric. and Forestry, Univ. of Mosul, Iraq ABSTRACT A nursery experiment was conducted in the College of Agriculture and Forestry, University of Mosul, Ninevah, Iraq to evaluate the effects of soaking periods (12 and 24 hours), Gibberellic Acid ( 0, 100 and 200 mg.l-1 GA3) and Benzyladenine (0,50 and 100 mg.l-1 BA) on pistachio seeds germination and subsequent seedlings growth of Pistacia vera Ashoury cultivar.Soaking seeds for 12 hours in (200 mg.l-1 GA3 + 100 mg.l-1 BA) showed the highest germination percentage (88.5%). Better seedling growth parameters (seedling height and diameter) were obtained with seed soaking in 200 mg.l-1 GA3 for 12 hours, while the internode length was significantly improved by soaking seeds in 200 mg.l-1 GA3 for 24 hours . Dry weights of seedling shoot and root were significantly increased by soaking seeds for 24 hours in (200 mg.l-1 GA3+100 mg.l-1 BA) and 24 hours in (200 mg.l-1 GA3), respectively. INTRODUCTION Pistacia is a genus of the Anacardiaceae family which are widely known trees and shrubs (Onay , 2000) . Pistachio seeds were used in commercial production for rootstocks ( Hartmann et al. , 2002). Usually, pistachio don’t propagate well from cuttings, so they are grafting or budding on various rootstocks due to difficulties in rooting of soft and hard cuttings (Sakoury , 1976 ; Onay , 2000). Seedlings rootstocks of Pistacia vera made more lateral roots and thicker stems than the other species and they can reach budding size in a shorter time (Ayfer et al. , 1990) .Ashoury is one of three main commercial Syrian pistachio cultivars which represents 85% of cultivars in Aleppo pistachio orchards (Padulosi and Hadj-Hassan , 1998 ; Tubeileh et al. , 2004).Gibberellins (GA) is an important endogenous growth regulator which has profound and diverse effects on plant growth and development. One of the roles of gibberellins is induction of seed germination and the promotion of radical elongation and mobilization of endosperm reserves during early embryo growth , as well as flower and fruit development ( Hopkins , 1999 ; Peng and Harberd , 2002 ; Hartmann et. al. , 2002). Cytokinins is among the most important hormones in regulating cell division and has the capacity to initiate division in quiescent or nondividing cells, in addition to stimulating cell division , cytokinins also influence shoot and root differentiation in tissue culture , the growth of lateral buds, leaf expansion , chloroplast development and leaf senescence .
