In grapes, a combination of variety, management, and training system dictates how much quality fruit the plant can produce. One of the best options is using fertilizer applied in the spring that can be easily taken up by the vine. Over the last four years, we have been looking at what AgroLiquid products can do on grapes. All fertilizer is soil applied in the spring underneath the vines.
- Conventional Program: 12 gallons of 28%UAN + 12.9 gallons of 10-34-0 + 100 lbs. of sulfate of potash.
- Agroliquid Program: 11 gallons of High NRG-N + 4.2 gallons of Pro-Germinator + 4.2 gallons of Sure-K + 1 gallon of Micro 500 + 0.125 gallons of Manganese.
