Product description

PROTAN®N9 is a liquid organic compound produced by hydrolysis of natural regenerative collagen protein. The high content of organic nitrogen, completely water-soluble and directly available for the plant is guarantee for a high nutritional value without leaching losses.

PROTAN®N9 is particularly recommended for localized soil irrigation and fertigation. All plants in general do respond well to PROTAN®N9 applications. The use of the product is possible at any time, but particularly recommended when the plant is enduring the greatest metabolic effort: transplantation, vegetative growth, flowering, ripening and maturation. Apply regularly PROTAN®N9 to feed your plants, favour microbial flora and improve the texture and structure of the soil. Increased root growth and a balanced crop development will raise the quality and quantity of your agricultural production.

Beyond the positive influence on the vegetative development of the plant, PROTAN®N9 amino acids help preventing and correcting micronutrient deficiencies by improving the soil retention and transportation of microelements. Amino acids and short chain peptides act as natural chelates and carriers when applied in combination with microelement fertilizers on the root. The chelating effect with certain amino acids such as glycine enables cation microelements like Iron, Calcium, Zinc, Manganese and Copper to „ligate“ (link) with amino acids, form a metal complex and be more easily assimilated by the root. The natural chelate and carrier properties of amino acids counteract leaching losses of microelements, enhance root absorption efficacy and reduce the application doses of microelement fertilizers.

Besides the soil application just described, the long chain peptides responsible for the natural viscosity of the product and the short chain peptides responsible for the chelate and carrier effect recommend a foliar application in combination with all common pesticides, plant growth regulators and foliar microelement fertilizers to enhance their efficacy and reduce the application doses.

The natural viscosity of PROTAN®N9 also recommends a leaf application as natural wetting enhancer. During drought the long chain peptides create a barrier that reduces water loss by transpiration (film-forming effect).

PROTAN®N9 is free from synthesis amino acids and any chemical components that could be harmful to the soil and crops. Because of the complete water-solubility and absence of any precipitation that could clog filters and nozzles of the irrigation system we also recommend PROTAN®N9 for the use in hydroponic systems.

Directions for use

We recommend PROTAN®N9 for fertigation and localized soil irrigation:

ml/hl H2O / application
L/ha / application
ml/m3 H2O / application
ORGANIC NUTRITION (up to 15 % of total Nitrogen demand) 10 – 20 L
once/week up to 6-8 times
50 – 100 ml/m3
over vegetative plant activity
NATURAL CHELATORS 2 – 3 L together with
deficiency corrector

With the exception of the olive grove where the product can be associated with copper and copper based fungicides, avoid mixtures with compounds incline to strong alkaline reaction, oil-based insecticides, polysulphides and compounds based on sulphur, tin and copper.

Dilute PROTAN®N9 before using it on plants. In case of inexperienced handling, we recommend a preliminary test on small areas before extending the treatment to the entire culture. The dosages advised are purely indicative and may vary depending on crop, crop vegetative cycle, climatic conditions and average yields expected.

Handling and storage

PROTAN®N9 is stable when stored under normal undiluted conditions. The original product in the state in which it is delivered is hazard–free concerning the transmission of pathogens. Close package properly after use and store in a frost-free place. Avoid storage at direct sunlight to keep the natural light colour of the product. Viscosity of the product at low temperatures affect the flowing life of the product.
