Biosol is perfectly well tolerated by plants, which responded with better growth, a deeper green of the canopy, the formation of a more complex root system, and a well balanced nutritional condition.
The special organic fertilizer BIOSOL was tested with regard to its effect on potted spruces cultivated on brown earth/semi-podsol and /or virgin soil substrates. The variants compared in the trials also included untreated controls and a mineral fertilizer variant. Particularly favorable results were achieved when appling Biosol on virgin soils with a low sorptive effect, where easily soluble mineral fertilizers can cause root etchings and are often washed away quickly. According to these results, Biosol can be recommended as a fertilizer for afforestaions in high altitudes and on virgin soils; the application of Biosol is a suitable measure to be taken in order to improve the growth and general health of the plants and to lessen the stress by transplanting.
Concerning the Application of Special Organic Fertilizers with Difficult Afforestations

Due to its slow release characteristics BIOSOL is considered superior to soluble inorganic fertilizers for high elevations sites with soils of low absorption capacity and high leaching potential.
BIOSOL was tested as an alternative to mineral fertilizers in field experiments designed at revitalizing Norway spruce stands affected by forest decline in Lech, Vorarlberg. Basal area increment responded positively and significantly to both mineral fertilizer and Biosol. Foliar nutrient levels increased only slightly and no major changes in soil microbial activity or mycorrhizal statue was observed. Thus fertilization with moderate amounts of fertilizer seems to be a safe method to increase tree vigour without dramatically changing site parameters.

Iron Chlorosis Deficiencies
Biosol and Biosol Forte fertilizers alleviate iron nutrition deficiencies of the plants when the level of available iron is low.
In another trial in a vineyard it was observed that chlorosis (Iron deficiency) of grapes was reduced after fertilization with Biosol.
Explanation of: Hydroxamate Siderophores:
Iron is an essential micronutrient for plants. Deficiency of iron causes growth disorder (iron chlorosis for example). One of the reasons for iron deficiency is that the iron is fixed very strongly in the soil and is not available for the plants. Hydroxamate siderophores are able to change the structures where the iron is fixed. So the iron can be used by the plants. Hydroxamate siderophores are produced by micro-organisms (fungi or bacteria) in the soil.
In this study the researches tried to find out whether if it is possible to rise the content of hydroxamate siderophores in soil through fertilization. They tested Biosol, Bactosol, chicken dung and grape mark compost.
The results indicate that Biosol as well as Bactosol lead to remarkable higher concentrations of siderophores.

Dry mycelium was proved by this study, as well as other studies to behave as an efficient organic fertilizer. Plant growth was enhanced several fold in treated plots compared to controls.
DM significantly reduced galling by 40%-53%
In 1987 Rocky Mountain Bio Products started with one organic product called “Biosol”, a natural organic product. Over several years we slowly added other high quality products to our product line. Biosol Forte was added as an economical alternative to Biosol, while producing the same great results. Earthgreen’s Menefee Humate, a micro nutrient and trace element product, was added to allow us to supply these important micro nutrients for those plant and soils that need it.
