Calkonutrium® + Bio

Calkonutrium®

Choose Calkonutrium® for the nourishing support of beneficial micro-organisms in your soil. Calkonutrium® can be added to any of our fertilisers.

Calkonutrium® contains two microbial species Bacillus Amyloliquefaciens and Trichoderma Asperellum. Calkonutrium® + has one extra species: Aztobacter.

Bacillus Amyloliquefaciens

Rhizome bacteria with a strong plant root symbiotic relationship. It produces the enzyme amylase which turns starch into sugars. It quickly colonises the plant root zone. Its main function is the production of an antibiotic called Plantazolicin. This is effective in killing or inhibiting the following microbes:

Ralstonia, which causes wilt in tobacco, tomatoes, and peppers.
Pythium, which is responsible for root rot, and can’t be destroyed by crop rotation.
Rhizoctonia, which attacks the roots of seedlings, causes turfgrass disease, bare patches in cereal crops, and crown rot in beetroots.
Alternaria, a fungus that affects a huge array of plants, including tomatoes, grapevines, strawberries, and cereal crops.
Fusarium, which attacks wheat crops and banana plantations through root rot and seedling blight.

Trichoderma Asperellum

A fungus that lives within the plant in a symbiotic relationship. It is found worldwide, grows rapidly and prefers high temperatures. It enhances plant growth and resilience by increasing uptake of phosphorus, atmospheric Nitrogen and buffering plants against salt stress, drought and poor soils.

It acts as an insecticide and herbivory by producing secondary metabolites that make plants

unappetizing or toxic. It is very susceptible to destruction by fungicides and chemical fertilizers.

Aztobacter

A very important nitrogen-fixing bacteria that forms strong-walled nodules on the plants’ roots. It requires well-aerated soils at a pH of 7-7.5 and a temperature around 20-30°C. It facilitates mobility of toxic heavy metals and produces 0.01mg of Nitrogen per gram of glucose consumed. It is a hardy bacteria that can survive in a cyst form for up to 24 years.
