Pure Fertilizer Effectivity Report – Dr Earth

Effectivity of Dr. Earth^®Premium Gold All Purpose Fertilizer
By: Milo Shammas, Founder & Formulator

OBJECTIVE:
The goal of this self-discipline trial was to match progress effectivity of Dr. Earth^® Premium Gold All Purpose Fertilizer with completely different commercially obtainable, pure/pure all-purpose fertilizers all through the spring and summer time season rising seasons. Effectivity was interpreted by measuring:
• Plant color
• Yield (by weight) of harvested fruit.

LOCATION:
The enlargement trials had been carried out in Vacaville, California on agricultural land that had been fallow for 3 years. The soil was a sandy-loam soil. Soil samples from the very best foot of soil in all plots yielded pH measurements ranging from 7.2 to 7.5.

EXPERIMENTAL PROCEDURE:
Randomly chosen tomato crops had been planted inside the ground in seven separate test plots. Each plot measured 6 ft x 9 ft. The crops had been equally spaced, separated by a distance of 36 inches measured from elementary stem to elementary stem. All plots had been situated to acquire equal daylight publicity. All plots had been irrigated using a timer-controlled, pressure-regulated, drip-irrigation emitter system. The system delivered equal portions of water at an equivalent events to all plots. Irrigation was elevated periodically and equally for all plots as a result of the crops elevated in measurement.

Planting date: April 22, 2004
Harvest dates: Six harvests between August 17, 2004 and September 22, 2004.
Each plot contained six tomato crops (Huge Boy choice). All crops had been purchased in pony pack containers on April 21, 2004. Vegetation had been randomly chosen from the equivalent provide and had been of comparable measurement (20cm. extreme x 10cm. big) and in comparable (good) scenario. Six of the seven plots had been fertilized on the time of planting with the completely completely different pure fertilizer merchandise acknowledged as follows:
• Dr. Earth^® All Purpose Fertilizer 4-4-4
• WF (5-5-5)
• EBS (5-5-5)
• DTE (4-6-2)
• FF (5-5-5)
• GM (5-5-5)

The seventh plot was the administration plot and obtained no fertilizer.

The pace of fertilizer software program was based on each producer’s solutions as printed on the fertilizer bundle.

A second fertilizer software program was made on June 27, 2004 at costs as soon as extra based on each producer’s solutions as printed on the fertilizer bundle.

Plant color was measured using a digital 6.3 mega pixel digicam. This digicam was used to {{photograph}} all of the plant area. The photographs had been quantified using a computer to rely the exact number of pixels (components) by the diploma of darkness for each plant.

Plant color was ranked from 1 to 9, with 9 being the darkest. Fertilizer impression curves measured how shortly the completely completely different fertilizers improved plant color, and the way in which prolonged this impression persevered. Plant color was measured weekly.
Each plot’s manufacturing was measured by weighing the combined yield of ripe tomatoes as harvested from all the crops in each plot. Vegetation had been harvested and weighed an entire of 6 events all through the self-discipline trial.

RESULTS:
Plant Coloration
The color of all crops dealt with with the completely completely different fertilizers is detailed in Desk 1. Dr. Earth had the darkest whole widespread color rating at 7.4. The standard color rating for crops dealt with with WF, EBS and DTE was 7.2. GM and FF had the underside values, each measuring 7.0. The overall widespread color rating for the administration group was 5.6.

Desk 1. Darkness of color (values 1 to 9) in crops dealt with with completely completely different enterprise pure plant fertilizers in Vacaville, California all through April 22, 2004 via September 22, 2004.

Desk 1, columns 1 via 6, illustrate the impression of the fertilizers on the color of the plant foliage.
The time required to understand a color price of at least 7.5 after preliminary fertilization numerous among the many many completely completely different fertilizers. Vegetation fertilized with EBS, WF, DTE each reached the 7.5 mark by the third weekly measurement. Dr. Earth, FF, and GM each surpassed the 7.5 mark, attaining a color price of seven.7, by the fourth weekly measurement.

Dr. Earth^® supplied the longest-lasting color impression. Vegetation fertilized with Dr. Earth^® maintained a color price of seven.5 or bigger for 13 out of twenty-two weekly measurements (59).

Vegetation fertilized with WF and DTE maintained a color rating of at least 7.5 for 10 out of twenty-two weekly measurements (45).
The crops fertilized with EBS maintained a color rating of seven.5 or additional for 7 weekly measurements (32). These crops fertilized with FF and GM surpassed the 7.5 mark for 4 weekly measurements (18).

PLANT YIELDS
Harvested tomato manufacturing of all crops inside the plots is detailed in Desk 2. The very best whole yield occurred in Plot #1, dealt with with Dr. Earth^® fertilizer. 395.1 lbs. of tomatoes had been harvested from this plot.
* Plot #2, fertilized with product WF, yielded 349.7 lbs.
* Plot #3, fertilized with product EBS, yielded 337.6 lbs.
* Plot #4, fertilized with product DTE, yielded 362.0 lbs.
* Plot #5, fertilized with product FF, yielded 328.0 lbs.
* Plot #6, fertilized with product GM, yielded 327.9 lbs.
* Plot #7, the untreated administration, yielded 201.8 lbs.

Desk 2. Full harvested weight of tomatoes in kilos. Six weekly harvests had been carried out August 17, 2004 via September 22, 2004.

Assuming fruit manufacturing is an indicator of whole plant nicely being, the outcomes counsel crops fertilized with Dr. Earth^® had been in the perfect nicely being, strongly suggesting that the nutritional vitamins geared up had been utilized at optimum ranges as compared with the alternative fertilizers examined.
