Comments

These samples were taken in the area of the young trees where the SSO and [microbial mixture] were drilled under water pressure in the root area approximately 3 weeks prior to sampling. The untreated area was only three to four feet away from the treated tree in the tree row. There are some significant changes in the readings between the [microbial mixture] and SSO treatment and the untreated soil both shallow and deep. In summary these are the changes made:

(1). Slight reduction in alkalinity both shallow and deep. At the present time, there is not a great significant difference, and only with time and more testing will we know if further reductions in alkalinity will take place.

(2). The total soluble salts were reduced 42.3% in the top 0"-1.5 feet, and 55% at the 1.5' to 3.5 foot level. These figures are very significant. In other tests taken in treated winery Still Slop Waste Ponds, the salts continue to be reduced with time.

(3). The soluble Calcium and Magnesium salts were reduce 23.6% in the top 1.5 feet, and 12.5% from 1.5 feet to 3.5 feet. The soluble Calcium and Magnesium salts down deep however, are very low, so the change from 1.6 meq./I to 1.4 meq./I is not significant.

(4). The soluble Sodium was reduced 67% in the top 1.5 feet of soil, and 56.2% from 1.5 feet to 3.5 feet. These figures are very significant.

(5). There was a slight increase (111%) in the carbonates and bicarbonates in the top 1.5 feet from 3.2 meq./I to 3.6 meq./l, and a slight decrease (2%) from 5.1 to 5.0 meq./I from 1.5 to 3.5 feet. These figures are not significant at this time, but in other tests at the winery ponds, these levels were reduced significantly, (35%) in the 0" to 1.0', and (52.9%) from 1.0' to 2.0'. These reductions have been accomplished over a four-month period, and I would expect the same at this location.

(6). The Chloride salts are low both shallow (0"-1.5') and deep (1.5'-3.5'). There was a slight increase in the top 1.5 feet from 0.1 to 0.2 meq./I. Down deep the Chloride levels were reduced from 2.6 meq./I to 0.1 meq./l, or a 96% reduction. These are not significant because the levels are low to begin with. Reductions in Chloride levels were very significant in the winery waste pond where the levels were much higher: (94% in the top 1.0') and (92% from 1.0' to 2.0').

(7). The Nitrate Nitrogen was reduced 45% in the top 1.5 feet of soil, and 96% from IS to 3.5'. In comparing with the winery waste treatment where there was a 96% reduction in the top 1.0' of soil and a 61.4% reduction down deep in a four month period. Even though there is a reduction in the Nitrate Nitrogen, I do not believe this is undesirable, because it is my opinion that there is a conversion of the Nitrates into Ammonia (or Nitrites), and into protein (bacteria bodies) which will be released at a later time to the plants. Also, the reductions are not below the optimum needs of the plants (25 ppm or more); and this is true in the winery ponds after four months. I am also sure part of the reduction is due to the utilization by the trees or the weeds in the ponds. The Nitrates do not appear to be moving past the 3.5 foot level in the ponds because the readings from 2' to 3.5' were very low, therefore, I am assuming a conversion and utilization is taking place.

(8). The Phosphorus levels were also reduced 29% in the top 1.5 feet, and 68% down deep (1.5' to 3.5'). Comparing with the winery ponds where a reduction of 23.7% in the top 1.0 feet, and 19.6% at 1.0' to 2.0' in four months, the Phosphorus levels in the ponds are approximately 5 to 7 times higher than in the soil on the Poppy Rch.; but once again, the levels are reduced, but not below what the crop needs would be.

(9). The Potassium levels were reduced 15.5% in the top 1.5' of soil, and 43.4% down deep from 1.5' to 3.5'. In comparing the reduction of Potassium in the winery ponds where we found a 37.9% reduction in the 0"-1.0' of soil, and a 47.2% reduction down deep from 1.0' to 2.0' after four months. Once again there must be a conversion of the Potassium into other compounds we are not testing for, and the plants are utilizing a portion of the Potassium to account for some of the reduction. In the ponds, there was not a significant increase in the Potassium from the 2' to 3.5' level, indicating the Potassium was either in equilibrium in the exchange, or it was not moving deeper in the soil after a four month period.

(10). The Boron was reduced 29.6% in the top 1.5 foot of soil, and there was no Boron in the untreated soil at 1.5' to 3.5', but the treated soil read 1.6 ppm. Indicating a movement of Boron downward in the treated area as opposed to the untreated area.

(11). The Zinc and Copper levels were undetected at both locations both shallow and deep.

(12). There was not a significant difference in the Iron and Manganese levels in the top 1.5 feet of soil, and both are very low. Down deep, there was a slight increase in the Iron and Manganese, but the levels are very low, so it is not a significant change. The ponds, after four months, are showing an increase in available Zinc from 5.9% (0" to 1.0') to 26% at 1.0' to 2.0 feet. Manganese in the ponds shows a 26% increase in the 0* to 1.0' of soil, and a 42% increase down deep at 1.0' to 2.0'.

(13). In the ponds, the Iron showed an increase of 10.16% in the top 1.0 feet of soil, and an increase of 135% down deep (1.0' to 2.0') in a four month period.

(14). In the ponds, the Copper showed an increase of 3.5% in the top 1.0 feet of soil, and an increase of 90% down deep (1.0' to 2.0') after four months.

(15). There is a substantial change in the exchangeable cautions on the Poppy Rch. as follows: 

 0"-1.5' Untreated Treated with [microbial mixture] & SSO

•  Exch. K - 412 ppm Exch. K - 348 ppm.
•  Exch. Na - 1460 ppm Exch. Na - 600 ppm.
•  Exch. Ca - 7600 ppm Exch. Ca - 6300 ppm.
•  Exch. Mg. - 820 ppm Exch. Mg - 800 ppm.
•  Exch. Sodium Percentage - 14.19% Exch. Sodium Percentage - 7.46%
• This is a substantial reduction of 47.4% in the exchangeable Sodium percentage, bringing this figure into
• a satisfactory range for good soil structure.

 1.5'-3.5' Untreated Treated with [microbial mixture] & SSO

•  Exch. K - 212 ppm Exch. K - 120 ppm.
•  Exch. Na - 3250 ppm Exch. Na - 1700 ppm.
•  Exch. Ca - 4200 ppm Exch. Ca - 4800 ppm.
•  Exch. Mg. - 750 ppm Exch. Mg - 780 ppm.
•  Exch. Sodium Percentage - 38.64% Exch. Sodium Percentage - 22.97%
• This is another substantial reduction of 40.6% in the exchangeable Sodium percentage, even though the level has not dropped below 10% for best soil structure.

In the winery ponds, the exchangeable Sodium percentages dropped 71.85% in the top 1 foot of soil, and 39% in the 1 to 2 foot level in a four month period.
