The Science of Silicon

The science behind Agripower’s Agrisilica® is compelling

The results proven and profitable. Agrisilica® is the cornerstone of healthy soils and healthy crops.

Silicon is found naturally in soil and water. Why add more?

Silicon (Si) is second only to oxygen as the earth’s most abundant element. However, in order to be taken up by plants, silicon must be in soluble form: monosilicic acid or orthosilicic acid Si(OH)4 – also known as Plant Available Silicon (PAS).

PAS in nature is often not available in sufficient quantities for crops, due to leaching, being bound to other soil minerals, or loss caused by soil erosion. Agripower’s Agrisilica® contains a uniquely high amount of PAS. One of nature’s key building blocks, plants need silicon for growth, strength and reproduction. Agripower’s Agrisilica® delivers PAS in dry or liquid fertiliser options, revitalising and conditioning soils, and improving plant biology actions which stimulate growth and protect plants.

Soils need Silicon

Balanced soil biodiversity and good soil structure are essential to plant health and crop success. Agripower’s Agrisilica® – with its high PAS content, accelerates and enhances natural physical, chemical and biological biology principles to deliver condition and health to soils with immediate results and long-term performance.

Important environmental benefits from adding PAS to soils include:

  • Reduced greenhouse gas emissions (particularly nitrogen volatilization)
  • Reduced water consumption
  • Reduced nutrient leaching and run-off into ground water, water systems and oceans (less aquatic/marine ecosystem damage)
  • Increased carbon sequestration in soils and plants.

Optimising Nutrient Outcomes

Crop results are determined by the resource in least supply – the ‘Law of the Minimum’. Whilst soils and water contain silicon, it is commonly not available in either large enough quantities or in the form that plants can take up and utilise or soils benefit from.

Silicon, in plant available form, will:

  1. Deliver its own specific benefits to soils and plants
  2. Optimise fertiliser performance – traditional fertilisers including NPK, MAP and DAP will have their benefits optimised when accompanied by Agrisilica®.

AAPFCO and other key organisations have recognised the value of plant available silicon as a beneficial nutrient in agriculture.

Powered by Agrisilica®

Adding Agrisilica® (high in PAS) increases photosynthesis:

  • Plant leaves are held more upright capturing more sunlight, increasing photosynthesis rates
  • Reduces lodging, make plant more erect
  • Increased photosynthesis results in increased plant energy and increased root growth
  • Increased root growth results in increased capture and uptake of more nutrients and water.

Adding Agrisilica® (high in PAS) increases crop resilience to Abiotic & Biotic crop stresses:

  • Plant less susceptible to extreme conditions e.g. drought, salinity, alkalinity, heat, frost
  • Transpiration rates are lowered (reducing water loss)
  • PAS is stored in growing points as phytoliths.
  • PAS includes plant’s natural defence responses to pests and pathogens via a combination of:
    • Physical measures (increased plant cell wall thickness) and
    • Biochemical measures (increased antioxidant and enzymes activities).
Adding PAS with Agrisilica® ameliorates and conditions soils, giving plants an improved foundation:
  • Improves soil structure (oxygen)
  • Increases plant root growth for improved uptake of water and nutrients
  • Increases soil organic matter
  • Increases soil’s water holding capacity, more water available to plant as needed
  • Increases soil biology / microbial activity
  • Harmful minerals (e.g. aluminium, cadmium, sodium) are ‘locked up’ in the soil
  • Leaching of valuable nutrients is reduced.

Agrisilica® reduces crop loss

Abiotic and Biotic plant stress cause up to 82% crop losses globally threatening food security and farmer incomes.

Powered by Knowledge

The value to agriculture of silicon to crops has been well established for over 70 years. Now, with 100% natural PAS-enriched Agrisilica®, agriculture is enjoying the ‘power of differentiation’. Agripower invests continually in knowledge building as climate change, food safety, environmental protection and food security present challenges to 21st century agriculture.
