There comes a point in every long-running problem where the evidence becomes too obvious to ignore. For many of the bowling clubs that get in touch to ask about solving green performance problems, I think they are now at that point with sand.
After another summer of heat, dry patch, weak turf, hydrophobic soil, disease pressure, uneven surfaces, irrigation panic and increasing renovation costs, the question can no longer be: “What top dressing are we putting on this autumn?”
Phosphite (PO₃³⁻) is a reduced form of phosphate (PO₄³⁻), the familiar phosphorus source in traditional fertilisers. Although the two compounds are chemically related, their behaviours in plants and soils differ significantly. Phosphite is highly soluble and readily absorbed through both roots and foliage, making it a highly efficient delivery mechanism for phosphorus-related benefits, including disease and pest resistance, acting as a trigger for some of the plant's remarkable natural defence mechanisms.

Localised Dry Patch doesn’t disappear just because summer is ending. Evolve G Granular Wetting Agent is the perfect addition to our NotDressing autumn renovation programme, helping autumn rainfall penetrate stubborn hydrophobic areas and continuing the work on LDP quietly in the background through the wetter months, before next summer exposes the problem all over again.
As standard soil analysis offerings are generally obsessed with chemistry, a very low pH is often interpreted as a chemical imbalance, which, of course, it is. The question of why those acid cations are dominant on the soil colloid, remains unaddressed in most cases. Instead it seems that many advisers are jumping straight to the temporary, artificial correction advice to add lime, and as we have seen, for fine turf, that can be dangerous advice.
