Summary:

The measurability of the P-Value is a new, objective method for determining the inner quality (biological) quality of food.

In this study 17 different fertilization variants were tested in an apple culture with regard to their effect on the P-Value. The lowest P-value, i.e. the highest biological quality was found in the samples treated with Biosol whereas the highest P-values were obtained in the variants with foliar fertilizers.

Summary:                              

The purpose of the trial was to examine, which measures can counteract the yield decline and quality deterioration resulting from the conversion to organic blueberry growing. Agro Biosol (now Biosol) produced impressive results, in particular with regard to yield

Summary:                              

The infection pressure of cabbage club-root cannot be reduced by fallowing. A clearly lower infection pressure was achieved when using Agro Biosol.

Summary:                              

Biosol, Vinasse and hair meal pellets were compared with regard to their effect on the yield and the size of cauliflower heads.Whereas the yield in the Biosol variant was slightly lower than the variant treated with hair meal pellets, fertilization with Biosol showed significantly higher results in salable goods.

Summary Apart from the nutrient quantity, the type of fertilization is also very important for the nitrogen efficiency. With regard to grain yield, Agro Biosol (now Biosol) proved to be superior even to the variant containing mineral KAS (calcium ammonium nitrate).

Summary The work group Steinobststerben (SOS – stone fruit dieback) has found during the study that, by adding chitin to the soil, chitin-degrading fungi are activated which are able to degrade the chitin-containing spores of T. basicola.

Summary Due to the high percentage of chitin in Biosol, the chitin-degrading microflora is promoted, which results in a reduction of the infection pressure of the parasites.

Summary:                              

The crop yield of Biosol is slightly, but not significantly higher than that of the reference fertilizer. However, plants are able to utilize nitrogen from Biosol more efficiently. In addition, there is a clearly lower nitrate content in the fresh mass of spinach treated with Biosol.

Summary:                              

Agro Biosol promotes fungi with mycoparasitic action, as well as nitrogen-mobilizing organisms in the soil. There was a positive effect on the number of fruits. In the second year of the trial, the variant treated with Agro Biosol had a higher Nmin content which indicates a long-term effect of Agro Biosol.

Summary:                              

The effect of Biosol and castor meal in organic farming were tested in a pot experiment. The yield of Biosol was higher compared to the other variants, caused by a more rapid N-mineralization and a better nutrient uptake due to a better root penetration.

Summary:                              

Despite the good nutrient supply, Biosol and Biosol Forte can have a positive effect on the yield as well as on the quality. In addition, the chlorosis of the vines was effectively controlled by these biological means.
