Polymer urea as a foliar feed: proceed with caution I have seen one or two trials recently where people have used a polymer urea as a foliar feed. I feel this is a complete disaster waiting to happen and was not surprised to see poor results! When polymers are used on the leaf they can sit around and clog up stomata if they are the wrong type of polymer.  They can be very slow on uptake and not have the appropriate effect to maximise yield potential of the growing plant. The inappropriate...

As we head towards the end of the year, it feels like a good moment to pause and reflect on a conversation we recorded back at the end of October – a snapshot of farming thinking at a time when very little felt settled.

Redox … Reduction-oxidation. What redox tells us about soil health This is a method of testing the number of electrons within the soil / plant, which is a very good way of assessing soil health. Nutrient availability is directly related to Redox state of the soil.  With nutrients such as nitrogen, phosphorus, iron and manganese, which all relates to the amount of oxygen within the soil as this determines the number of electrons and nutrient availability.
