In terms of the Right Rate component of the 4Rs, the folks at AgroLiquid are taking a novel approach to finding it through research and unique method of monitoring the fertility in the liquid between the soil particles.
Using a series of syringes attached to tubing placed at varying depths beneath the soil, the soil solution underground can be carefully extracted. The nutrient levels in the solution can then be compared to nutrient application rates to get a handle on what the plants are using and what is being lost.
“We have developed this method of how to test nutrients in soil solutions to see how much is lost. What we are doing has the potential to change how the industry approaches fertility and the loss of nutrients,” said Nick Bancroft, vice president of AgroLiquid. “We test the nutrient solution to see what nutrients are moving in the soil and compare that to what was applied and see what amount was used and what amount was lost.… Continue readingRead More »
