Product Type
Silicon and potassium nutrient corrector complexed with amino acids
SIL AA
Silicon and potassium nutrient corrector with plant amino acids for rapid uptake, abiotic-stress support, root development, crop quality and yield.
SIL AA is a concentrated silicon and potassium nutrient corrector supplemented with plant amino acids. The amino-acid complex is designed to improve the uptake and distribution of silicon and potassium within the plant.
The formulation is intended for foliar use across annual and perennial crops and can also be used in soil, drip-irrigation and hydroponic nutrient solutions. The source positions it for crop resilience, root-system development, post-harvest life, quality and yield.

Key benefits and agronomic effects
- Supports high uptake and transport of silicon and potassium.
- Supports crop resistance to abiotic stresses.
- Supports natural resistance to fungal pathogens and pests, as stated in the technical document.
- Supports post-harvest life and produce appearance.
- Supports intensified root-system development.
- Supports crop quality and yield.
How it works / Technical advantages
SIL AA combines silicon and potassium with plant amino acids in a highly miscible and soluble liquid formulation. The source states that the amino-acid complex improves uptake and distribution of Si and K in plants.
The technical document also links silicon treatment with longer post-harvest life, noting research on reduced ethylene-related ageing and longer maintenance of chlorophyll content in harvested plant material.
Application rates and timing
Application Guidance: For foliar use, apply 1-2 L/ha or 200-400 ml/100 L in a minimum of 600 L water. Annual crops are treated every 10-15 days from the first visible leaf; perennial crops during leaf flush, after fruit set and every 10-14 days during disease events. For soil, drip or hydroponic nutrient solution, use 200 ml/1000 L, 6-8 times per crop cycle, with a maximum of 8 L/ha.
Soil application
| Crops | Timing | Dose | Notes |
|---|---|---|---|
| All suitable crops | 6-8 applications per crop cycle | 200 ml/1000 L nutrient solution | Application method: Soil application. Maximum total use: 8 L/ha. |
Foliar application
| Crops | Timing | Dose | Notes |
|---|---|---|---|
| Annual crops: vegetables, cut flowers, nursery crops, strawberries, sugarcane and wheat | Every 10-15 days from the first visible leaf onwards. For best results, begin before leaf hardening. Apply to sugarcane during the lead-up to the drier months. | 1-2 L/ha or 200-400 ml/100 L | Apply in a minimum of 600 L water. |
| Perennial crops: tree crops, vines, bananas and turf | During leaf flush and after fruit set; repeat every 10-14 days during disease events. | 1-2 L/ha or 200-400 ml/100 L | Apply in a minimum of 600 L water. |
Fertigation / drip irrigation
| Crops | Timing | Dose | Notes |
|---|---|---|---|
| All suitable crops | 6-8 applications per crop cycle | 200 ml/1000 L nutrient solution | Application method: Drip irrigation / fertigation. Maximum total use: 8 L/ha. |
Other applications
| Crops | Timing | Dose | Notes |
|---|---|---|---|
| All suitable crops | 6-8 applications per crop cycle | 200 ml/1000 L nutrient solution | Application method: Hydroponic nutrient solution. Maximum total use: 8 L/ha. |
Additional technical information
Target problem / deficiency symptoms
SIL AA is intended for silicon and potassium nutrition where crops require additional support for abiotic stress tolerance, root-system development, post-harvest performance, quality and yield. The source also positions it for supporting natural resistance to fungal pathogens and pests.
Mixing & compatibility
SIL AA is compatible with most pesticides except products with an alkaline reaction.
Frequently asked questions
What is SIL AA?
SIL AA is a concentrated silicon and potassium nutrient corrector supplemented with plant amino acids.
What is the composition of SIL AA?
It contains 26.4% silicon as SiO₂, 10.2% potassium as K₂O and 3% free amino acids on a % w/v basis.
What is SIL AA used for?
It is used to support silicon and potassium nutrition, abiotic-stress tolerance, root development, crop quality, yield and post-harvest life.
Why does SIL AA contain amino acids?
The source states that plant amino acids improve the uptake and distribution of silicon and potassium within the plant.
What is the foliar dose for annual crops?
Apply 1-2 L/ha or 200-400 ml/100 L in at least 600 L of water every 10-15 days from the first visible leaf onwards.
What is the foliar dose for perennial crops?
Apply 1-2 L/ha or 200-400 ml/100 L in at least 600 L of water during leaf flush and after fruit set, repeating every 10-14 days during disease events.
Can SIL AA be applied through drip irrigation?
Yes. The source gives 200 ml per 1000 L of nutrient solution, applied 6-8 times per crop cycle, with a maximum of 8 L/ha.
Can SIL AA be used hydroponically?
Yes. Hydroponic nutrient solution is specifically listed, using the same documented concentration of 200 ml/1000 L.
Can SIL AA be mixed with pesticides?
Yes. It is compatible with most pesticides except those with an alkaline reaction.
Does SIL AA support post-harvest life?
Yes. The source links silicon treatment with longer shelf life and longer maintenance of chlorophyll content after harvest.
What pack sizes are available?
SIL AA is available in 1 L, 5 L, 10 L, 20 L and 1000 L formats.
