Agriculture Introduction

When coupled with the correct technology, diatomaceous earth or natural amorphous silica can have a significant beneficial impact on the physical, chemical and biological processes of soil, water and the growth of crops. The biogeochemical cycle of silica is even more intensive than the Phosphorus or Potassium cycle in the terrestrial ecosystem.

The  biogeochemical  reactions  and  technology  can  be  adapted  to  address  other agricultural  problems such as salinity, water deficiency, water toxicity, heavy metal toxicity, soil pH extremes and chemical leaching. The agricultural practices of today have destroyed the vital  balance  of  the  soil  system  and  the  ability  of  the  soil-plant  system  to  function effectively. Silica is vital for an effective soil-plant system but has been critically deficient in agriculture for decades and this has led to a number of negative consequences. The lack of high grade amorphous silica has a massive effect on circumstances directly relevant to food production such as the amount of fertilizer required for maximum production, crop resistance to abiotic stresses (temperature, water deficiency, wind, salt, heavy metals, hydrocarbons etc) and biotic stresses (insect, disease, fungi etc).

Agricultural Natural Silica

Not all silica products are the same, some are high quality, some are low quality and some can have a negative effect in agriculture. In order to be beneficial in agriculture any amorphous silica product must:

1.  Provide a high level of water-soluble silica
2.  Have a high level of residual silica.
3.  Contain beneficial trace elements.
4.  Contain no toxic levels of any element, pollutants or heavy metals.
5.  A high level of plant available amorphous silica, if the silica you are currently buying or are considering has  low solubility then it is going to have little or no benefit to the plant at all.

Many Diatomaceous Earth amorphous silica products meet some of these requirements however, very few meet them all. Some products have high levels of silica but the silica is low in plant availability. Other products have high levels of plant available silica but it is contaminated with heavy metals and other toxins.

Food production

Natural Silica provides the plant with energy and reinforces the plant’s ability to protect itself against biotic and a-biotic stress, and soil treated with Natural Silica will have optimal fertility through improved water, physical and chemical properties and by allowing nutrients in the soil, such as phosphorus, to remain in a plant available form.

All crops benefit from silica nutrition.

 

Benefits for growers

Natural silica significantly increases crop yield which means increased revenue for growers. Natural silica provides the plant with energy and reinforced its ability to protect itself against stress. Soil treated with DE will have optimum fertility through improved water, physical and chemical properties and by allowing nutrients in the soil, such as phosphorus, to remain in a plant available form.

Increased production yields

All crops benefit from silica nutrition and when used as recommended, typically average a 15% to 35% increase in yield within the first season. Crops such as rice and sugarcane, which can take up more silica than nitrogen, typically average a 20% to 70% increase in yield.

The following photos show the benefits of using diatomaceous earth on crops at an early stage.
