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 product information at a glance.
| Composition | % w/v |
|---|---|
| Silicon (SiO₂) | 26.40 |
| Potassium (K₂O) | 10.20 |
| Free amino acids | 3.00 |
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 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.
| 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. |
| 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. |
| 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. |
| 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. |
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.
SIL AA is compatible with most pesticides except products with an alkaline reaction.
SIL AA is a concentrated silicon and potassium nutrient corrector supplemented with plant amino acids.
It contains 26.4% silicon as SiO₂, 10.2% potassium as K₂O and 3% free amino acids on a % w/v basis.
It is used to support silicon and potassium nutrition, abiotic-stress tolerance, root development, crop quality, yield and post-harvest life.
The source states that plant amino acids improve the uptake and distribution of silicon and potassium within the plant.
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.
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.
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.
Yes. Hydroponic nutrient solution is specifically listed, using the same documented concentration of 200 ml/1000 L.
Yes. It is compatible with most pesticides except those with an alkaline reaction.
Yes. The source links silicon treatment with longer shelf life and longer maintenance of chlorophyll content after harvest.
SIL AA is available in 1 L, 5 L, 10 L, 20 L and 1000 L formats.
