Cardy Twin Nitrate Meter

Cardy Twin Nitrate Meter

Put the power of a laboratory right in your hands!

Nitrogen is essential for healthy and high yielding crops. The current cost of nitrogen fertilizers requires growers to make well educated and accurate decisions regarding when and how much nitrogen is needed. Immediate in-field testing determines how much nitrate is already present, minimizing the possibility of wasted fertilizer.
