• Enhance soil & root growth


The Agribac line of products was especially developed to meet the commercial requirements of our clients for root crops (poatoes, sugar beet, carrots, kohlrabi) and also for tomatoes and cereals.

Agribac dissolves and mobilises fresh nutrients from the soil and produces growth hormones for the plants. Agribac supplements agents in conventional fertilizers and pesticides to produce larger root systems and tubers. Thus, Agribac increases the marketable proportion of the yield both in quantity and quality. Agribac forms a specific milieu with the root system of the plant which greatly limits the habitat and nutrients available for harmful bacteria and fungi and destroys typical soil contaminants.

From 1997 to 2002 field trials with potatoes, sugar beet and tomatoes were carried out by Plantbacter and independent bodies. In both cases, the layout of the treated (addition of Agribac to the seeds or, in the case of tomatoes, to the soil) and untreated plots was randomised.

Positive effects were found, particularly for potatoes. The marketable yield increased considerably in number and size as compared to untreated plants (depending on sort and cultivation conditions, up to 20 %), and there was a reduction in scabs caused by Streptomyces scabies.

During the 2000 cultivation period, the Schleswig-Holstein Agricultural Board made a comparative study of biological plant-strengthening substances on potatoes infested with Rhizoctonia solani.

Potatoes treated with Agribac had a 51 % higher marketable yield, as compared to untreated controls.

Further field trials were carried out in 2000, at locations in Germany with different soil and climatic conditions. The following positive effects were observed with cereals:

  • higher numbers of seedlings per m2
  • more – and longer – root systems of the shoots
  • higher proportions of ear-carrying stalks per m2
  • higher weight per thousand grains

Apart from various locations in Germany, trials with Agribac are being carried out at present in cooperations with China (various plants), Iran (potatoes, watermelons and pistachios) and Greece (olive trees). These trials are performed and analysed by our respective partners in these countries. In Hungary, treatment of olive trees, tomatoes and peppers with Agribac resulted in an increase in yield (10 bis 20 %) and an improvement in plant health.

Further positive results from the last cultivation period have been registered in China. In trials aimed at the prevention of potato disease, treated plants showed 12 % less infestation than the untreated controls. For effects against the fungi Phytophthora infestans, treated plants showed 67 % less infestation than controls.

The use of Agribac to improve growth and yield of potatoes, results in a stimulation of leaf and root development, which can be observed at the end of the growth phase by the size and number of leaves and the well developed root system. After the harvest, both the number and weight of the tubers was increased by the use of Agribac.

Agribac has positive effects on ornamental ferns regarding plant height, form and number of leaves. In all trials, ca. 20 % more leaves pro m2 were observed after treatment.

Trials with Chinese cabbage and kale were made to illustrate to what extent the use of Agribac can reduce the use of conventional fertilizers. The results clearly show that a reduction of conventional fertilizers is possible: 12 to 31 % with Chinese cabbage and 5 to 20 % with kale. Furthermore, high increases in turnover were found by using Agribac on mustard plants and growth increases of 10 to 25 % were determined with celeriac in clay soil.
