THE STRONG POINTS OF OUR ORGANIC SUBSTANCE
In addition to organic nitrogen, GRENA products feature the presence in percentage of macro-elements of organic origin, such as Phosphorus (from animal residues, and in particular from fish), Potassium and meso-elements such as Calcium (from egg shells), and micro-elements such as: Iron, Magnesium, Manganese, Molybdenum, Copper and Boron, naturally present in mg/kg.
MAIN STRENGTHS:
Organic Matrix
Our basic organic matrix contains amino acids from the hydrolysis of proteins. Amino acids are an excellent source of nutrition for the soil flora and therefore their use allows the microorganisms that live in the soil to thrive.
Slow release
Nutritional elements are released gradually; for example, in order to be fully released Nitrogen needs the carbonization of the organic substance to be slow and constant.
No added salinity
Our products do not carry extra salinity that could create problems for crops (especially vegetables, such as salads, or fruit such as strawberries).
Moisture
Humidity is levelled at 7% to obtain a good pellet product. Our pellets are intended for distribution on land that will undergo further tillage and allow the pellets to be buried in the soil.
Micro form
Most of our fertilizers are also available in the micro version, which is obtained from crumbling our 4mm pellets.
Analysis and monitoring
Fortnightly analysis and monitoring of incoming materials guarantee the absence of antibiotics, infesting seeds and pathogenic germs thanks to the autoclave cooking.
Free from phosphites
GRENA organic products, solid and liquid biostimulants, organic and organo-mineral fertilizers do not contain phosphites.
