A research trial on watermelons was conducted at a production greenhouse to observe the effect of AZOMITEĀ® on the growth, production and quality in a small-plot trial. The test consisted of four treatment groups: One using a combination fertilizer at 660 lbs/acre; A silica fertilizer at 396 lbs/acre + combination fertilizer = 660 lbs/acre; AZOMITE at 396 lbs/acre + combination fertilizer = 660 lbs/acre; and a control group. Each treatment was randomly replicated three times, with a plot size of 323 ft2 (134.86th of an acre). Fertilizers and additives were blended and added to the soil, followed by the seedlings in April, with harvesting in July. The thickness of pericarp, sugar content in the center of the fruit as well as in the peripheral region, were recorded. Pest control and irrigation management were identical among all the treatments.

Benefits of AZOMITE

  • AZOMITE was able to improve growth rate, development, and viability
  • AZOMITE was able to increase the central sugar content in watermelon when compared against the control, combination fertilizer and silica fertilizer by 0.85, 1.25, and 0.25 degrees, respectively
  • AZOMITE was able to increase the yield of watermelon over all other treatments, from 22.31% over the control to 6.00% over the silica fertilizer group
