SilicaMax

51% SiO₂ + Broad Trace Elements

Silicon physically strengthens cell walls — making plants mechanically harder for insects and fungal spores to penetrate. SilicaMax delivers 51% SiO₂ in a non-crystalline, plant-available form that simultaneously activates rhizosphere biology and improves drought tolerance.

The Science

Most fertilisers feed the plant.
Ours feed the soil.

The rhizosphere — the microbially active zone around plant roots — determines how much nutrition your plants can actually access. BioCare formulations are designed to activate this zone, not just dump nutrients into it.

Silicon strengthens, not just feeds

SiO₂ physically hardens cell walls against pest and fungal entry — a mechanical defence that NPK alone can't provide.

Humic carbon improves cation exchange

Humic and fulvic acids from ancient Australian deposits help soil hold nutrients where roots can reach them.

Seaweed + fish + trace elements

The 44-Plus range uses biostimulants alongside NPK — improving uptake efficiency, not just nutrient supply.

Flagship Farming Formula

44-Plus

N 13.9 · P 3.7 · K 10.7 · S 10.7

The four biostimulants included alongside NPK — seaweed, humic acid, fish and trace elements — work synergistically to improve nutrient efficiency, soil biology and plant resilience in one application.

My citrus leaves are yellowing between the veins but the veins stay green

That pattern — yellowing between veins with green veins remaining — is classic iron or manganese deficiency. Common in alkaline soils where pH blocks uptake even when the minerals are present.

I'd start with EasyTrace as a foliar — it bypasses the soil chemistry issue entirely. You should see improvement in 5–7 days.

Grower results

From Australian growers.

Using SilicaMax across our operation for two seasons. Noticeably better plant health and the soil biology has really come alive. Went from needing three fungicide sprays to one.
