Providing the iron ions stably needed for plant growth.
Plants absorb iron in the ferrous (bivalent iron) form from the roots. Even as the earth is said to be a planet of iron, there is a lot of iron in the soil, however most of that is ferric (trivalent iron) that plants are unable to absorb in that form. Plants use their energy to turn trivalent iron into bivalent iron before absorbing it from their roots.
Our TetsuRiki Agri/TetsuRiki Aqua products are based on an understanding of the mechanisms at work within plants so that iron can be absorbed even if the plant is weak, such as in poor soil or weather, lead to cultivating healthy plants.
TetsuRiki Agri (Granule): Bivalent iron is provided continuously from ferrous oxide (FeO).
TetsuRiki Aqua (Liquid) : Ferrous iron is provided promptly by the nutrients in the organic ferric complex.

Why do plants need iron?
Vegetation carries out photosynthesis to create energy, and this function is performed by chlorophyll. When making chlorophyll from nitrogen compounds, iron is needed. Without iron, chlorophyll cannot be produced and the plant will be unable to photosynthesize. Soil with high pH or in a poor environment such as low warmth or low light, iron absorption suffers and the color of the leaves will become lighter. In these circumstances, providing easy-to-absorb iron restores the health of the plant.
Plant nutrition consists mainly of the elements nitrogen (N), phosphate (P), and potassium (K). Iron is one other essential nutrient. Without iron, even with enough of the other nutrients, the growth of the plant will be limited. In addition to synthesizing chlorophyll, iron is also used by mitochondria to produce energy and convert nitrogen fertilizer into amino acids.

The function of iron 1., Synthesis of chlorophyll (photosynthesis)
The function of iron 2., production of energy (respiration)
The function of iron 3., Synthesis of amino acids (metabolism)
