Bio Charge - SILARA N30
SILARA N30 is a New Zealand-made, high-surface-area amorphous colloidal silica concentrate designed to fit practical pasture, cropping, horticulture and viticulture programmes. A dissolved silicon fraction provides immediate availability, while the colloidal silica reservoir is designed to progressively release soluble silicon.
Available now. Available over time.
- Dissolved silicon fraction: provides an immediately available silicon component following application.
- Colloidal silica reservoir: designed to progressively release soluble silicon over time.
- High-surface-area particles: nanometre-scale amorphous silica provides a large reactive surface in a low-volume concentrate.
- Programme flexibility: designed to fit alongside compatible inputs in pasture, cropping, horticulture and viticulture programmes.
SILARA N30 is intended to support the plant as part of the wider nutrition and management programme for the intended crop.
Key pasture benefits
- Root development: supports stronger, deeper roots for improved access to water and nutrients.
- Plant structure: supports stronger stems and leaves and may help maintain a productive pasture stand.
- Photosynthetic performance: designed to support efficient photosynthesis and productive growth.
- Stress tolerance: supports the plant’s response to drought, heat and other environmental stresses.
- Nutrient efficiency: designed to work alongside nitrogen, phosphorus and other nutrients.
- Dry-matter potential: developed to support productive growth and more usable feed from every hectare.
Ideal for
- Actively growing pasture
- Suitable cropping, horticulture and viticulture systems, with crop-specific rate and timing confirmed by Bio Charge
- Pasture programmes using liquid nitrogen
- Urea and ammonium sulphate programmes
- Compatible foliar nutrition programmes
- Programmes using gibberellic acid, subject to compatibility testing
- Farms looking for a low-volume silicon input
- Pasture programmes focused on roots, resilience and dry-matter production
Application and mixing
Coverage
- 1 litre treats approximately 3.3 hectares.
- One 20-litre container treats approximately 66 hectares at the typical rate.
Mixing order
- Part-fill the tank: fill the spray tank one-third to one-half with clean water and begin agitation.
- Add SILARA N30: add the required amount while maintaining agitation.
- Add compatible products: add other fertilisers, trace elements or additives according to their label directions.
- Top up: fill the tank to the required water volume and maintain agitation through mixing and application.
Best results
- Apply to actively growing pasture and other suitable cropping, horticulture and viticulture systems. Confirm the appropriate rate, timing and compatibility for the intended crop and programme with Bio Charge. The 300 mL/ha rate is the typical pasture rate.
- Maintain agitation during mixing and application.
- Conduct a jar test before mixing with unfamiliar products.
- Use clean water and suitable application equipment.
Storage and handling
- Store in the original container away from direct sunlight.
- Protect from frost.
- Agitate before use.
- Clean application equipment after use.
- Always read and follow the current product label.
Research-led product development
Published silicon research provides a strong biological rationale for evaluating SILARA N30. The studies below used other silicon formulations, application methods and growing conditions, so their findings should not be treated as guaranteed SILARA N30 results.

Silicon support for pasture, cropping, horticulture and viticulture.
SILARA N30 is a high-surface-area amorphous colloidal silica concentrate designed to fit practical pasture, cropping, horticulture and viticulture programmes. It combines immediate silicon availability with a reservoir intended to release soluble silicon progressively.

Support the plant from roots to dry matter.
Root development
Supports stronger, deeper roots for improved access to water and nutrients.
Plant structure
Supports stronger stems and leaves and may help maintain a productive pasture stand.
Photosynthetic performance
Designed to support efficient photosynthesis and productive pasture growth.
Stress tolerance
Supports the plant's response to drought, heat and other environmental stresses.
Nutrient efficiency
Designed to work alongside nitrogen, phosphorus and other nutrients in the wider programme.
Dry-matter potential
Developed to support productive growth and more usable feed from each hectare.
A low-volume addition to the normal spray programme.
Mix with water and apply to actively growing pasture. At the typical pasture rate, one litre treats about 3.3 hectares and a 20-litre container treats about 66 hectares. Confirm the appropriate rate, timing and compatibility for other suitable cropping, horticulture and viticulture systems with Bio Charge.
Water first. SILARA N30 next.
Fill the spray tank one-third to one-half with clean water and begin agitation.
Add the required amount of SILARA N30 while maintaining agitation.
Add other fertilisers, trace elements or additives according to their label directions.
Fill to the required water volume and maintain agitation through mixing and application.
Compatibility: Confirm compatibility with the intended inputs and programme. Conduct a jar test for unfamiliar combinations and follow product labels.
Storage and handling: Keep in the original container, out of direct sunlight and protected from frost. Agitate before use, clean equipment after application, and always follow the current product label.
A strong rationale. A clear evidence boundary.
Published silicon research provides a serious basis for field evaluation across pasture and selected high-value crops.
SILARA N30 is designed for pasture, cropping, horticulture and viticulture programmes. Confirm crop-specific rates, timing and compatibility with Bio Charge. The studies below used different silicon forms, rates, crops and environments. They support the biological rationale and trial design, but they are not proof that SILARA N30 will reproduce the same results. Product-specific New Zealand trials are required before outcome claims are made.
Roots, recovery and dry matter
A 2025 perennial ryegrass study using another foliar silicon product reported 12.5% more root dry mass and 4.5% more shoot dry mass across the experiment. Its 100 g SiO₂/ha application was close to the gross loading calculated for SILARA N30 at 300 mL/ha, but the formulations and conditions differ.
Kiwifruit firmness and storage
Recent ‘Hayward’ research using orthosilicic acid reported higher firmness and lower weight loss, respiration and ethylene during storage and ripening. This supports New Zealand trial work; it is not a SILARA N30 orchard claim.
Potato yield under field conditions
Field work with foliar sodium silicate reported early-tuber yield increases in two seasons. The higher published rate, 46.5 g elemental Si/ha, closely brackets the approximate elemental-silicon loading at the SILARA N30 pasture rate, although product form and crop use differ.
Sweet cherry cracking and firmness
Direct sweet-cherry research using other silicon treatments has reported lower cracking and improved firmness, including a 71% lower cracking index in one 2025 study. A SILARA N30 cherry programme still requires its own crop-safety, rate and timing validation.
