GUMAT humates.   Summary of trials: 2007. Canada.

 

Pot trials to evaluate next stage trials. All trials were conducted outside, using large pots with a 60%-70% organic matter potting mix. All pots were watered twice daily. Seed variety used matched the local growing conditions, and used a basic chemical fungicidal seed treatment.

 

Winter wheat trial: Objective- to demonstrate that adding humate to the common granular starter fertilizer used in winter wheat that the early seed/plant growth could be influenced.

2007: planted August 11/07, evaluated September 6/07 at 28 days.

GUMAT Baikal was applied to MAP (12.5-50-0) dry starter fertilizer in-furrow (rate 100#/acre), with Baikal rate of 5kg/te and 10kg/te respectively. At the 10 kg rate the increase in average plant weight was 19.3% over untreated. At the 5kg rate the average plant weight was lower by 6.25% versus the untreated.

 

Urea side dress trial: Objective- to demonstrate that rates of urea side dressed on corn could be lowered when urea treated with humates.

2007: planted August 6/07, evaluated September 9/07 at day 34.

At 107#N/acre with GUMAT Baikal added at 5 kg/te, the plant weights were reduced by 2.9% versus 107#N alone.

At 64#N/acre with Gumat Baikal added at 5kg/te, the plant weight was increased by 10% versus 64#N with competitor product, and was 14.3% heavier than the average plant weight for 107#N/acre used alone. (64#N versus 107#N is a 40% reduction in N rate per acre).

At 50#N/acre the results were unclear. Plant weights were reduced compared to 107#N and 64#N/acre both. The reduction was 3.5%. However, based on plant tissue analysis, the 50#N/acre proved to have increased levels of P, Fe, Zn, B, as well as dramatically higher dry matter content (21.3% versus 7.5%). These values were double-checked at the laboratory and were verified as true.

 

Wheat seed treatment trial: Objective-to determine the best use of humates as winter wheat seed treatment application, applied to commercially fungicide treated seed.

2007: planted August 13/07, evaluated September 7/07 at day 25.

Baikal treated seed (250 gm/te in 10L water/te) increased average plant weight by 40.2% and 28.8% when compared to untreated control (no fungicide), and treated seed (with fungicide).

Gumat +7 at the same rate of application increased average plant weight by 22.5% and 12.6% respectively.

In a second phase of the trial the rates of application were reduced.

Baikal at full rate increased average plant weight by 27.5% and 17.1% versus untreated control and chemical treated seed.

Baikal at ½ rate increased average plant weight by 23.5% and 13.5% versus untreated control and chemical treated seed.

GUMAT +7 at full rate increased average plant weight by 30.4% and 19.8% versus untreated control and chemical treated seed respectively.

GUMAT +7 at ½ rate increased average plant weight by 21.6% and 11.7% versus untreated and chemical treated seed respectively.

 

Sweet corn trial:  Objective- evaluate effect on early sweet corn seed.

This trial showed that using several humates of different sources that the usual effect on sweet corn seed is to lower the average plant weight at ~50 days of growth. The corn seed structure makes the rate of use of humates critical. This trial showed an average plant weight reduction of 16% at ~ 50 days of growth. This was true for Baikal and GUMAT +7.

Best estimate is the rate of application needs to be 50 grams – 75 grams per tonne of seed.

 

Cellulose based agricultural granules/insecticide carrier: Objective- to use these carriers that are widely used in agriculture to deliver the humate to the root and fertilizer zone of activity.

Field corn. Planted August 12/07, evaluated Sept 01/07 at day 20.

Adding Gumat +7 DRY to the granules at 10kg/te and 20kg/te increased average plant weight by 11.1% versus carrier alone.

Adding Baikal DRY to the granules at 10kg/te increased average plant weight by 13.1% versus carrier alone.

Adding Baikal DRY to the granules at 20kg/te increased average plant weight by 17.1% versus carrier alone.

 

Field corn seed treatment trial:  Objective-to compare humate field corn seed treatments.

Planted July 7/07, evaluated August5/07 at day 26.

All seed treatments were used at the same 100 grams per tonne of seed. All seed was pre-treated with captan fungicide.

Control average plant weight = 44.67gm.

GUMAT +7 avg plant weight= 54.17gm

Baikal average plant weight=    77.50gm

Competitor avg plant weight=   73.00gm

Competitor avg plant weight=   76.00gm

 

Corn stalk cross sectional area was measured in this trial:

Control-stalk are in mm2 = 78.5

Baikal- stalk in mm2=         254.5

Competitor=                         153.96

Competitor=                         176.74

 

 

Field corn seed treatment rate trial: Objective- evaluate humate seed treatment rates on field corn.

Field corn, planted August 11/07, evaluated Sept2/07 at day 22.

Products are dissolved in water and applied to the seed. Seed pretreated with captan.

 

Results: Control        = 5.7 grams per plant.

              GUMAT+7 = 6.2 grams per plant (400 mg/lt)

              Baikal          = 6.9 grams per plant (400mg/lt)

              GUMAT+7 =  5.7 grams per plant (200 mg/lt)

              Baikal          =  6.4 grams per plant (200mg/lt)
