Briefly about: Ecolabelling for soil improvers

In the European Union, 60 products have been awarded with the Ecolabel and 17 licenses have been issued for the product group “Growing media, soil improvers and mulch”.  Ecolabelled products are produced by companies in Belgium, Denmark, Spain and Greece, but there are no products in this group awarded with the Ecolabel in Latvia yet.

What are the products involved in the group “Growing media, soil improvers and mulch”? “Growing medium” is a material used as a substrate for root development, in which plants are grown and a “mineral growing medium” is a growing medium that consists totally of mineral constituents. A “soil improver” is a material added to soil in situ with the main function to maintain or improve the physical and/or chemical and/or biological properties of soil, with the exception of liming materials. Specifically, “organic soil improver” contains carbonaceous materials and its main function is to increase soil organic matter content.

Briefly about: Granulation of fertilizers/soil improvers

Granulation is the process used for the production of pharmaceuticals, fertilizers, animal feed, various chemicals, also coffee, etc. obtaining granules which are dense grains of a substance. Granular fertilizers are usually 1-5 mm in diameter, produced from larger materials after they are crushed and sieved, or by bonding smaller particles during dry or wet granulation, thus obtaining a higher density almost round-formed particle material.

Finalized work on collaborative scientific paper draft

International and interdisciplinary discussion on marine waste evaluability and valorization possibilities have resulted in an impressive scientific article draft to be submitted for publication in the scientific journal “Frontiers in Marine Science” (IF=3.661).

The title of the manuscript: Valorization of marine waste, industrial by-products and biopolymers. Currently, the final corrections in the paper are made by the corresponding author Dr. Ana Rotter, senior research associate at Marine Biology Station Piran, National Institute of Biology in Piran, Slovenia.

Briefly about: Ecolabelling in Europe

Ecolabel is a voluntary form of certification (licensing/declaration) in the European Union applied to a product or service, through which the manufacturer or service provider informs consumers in a standardized way that the environmental impact of the product or service is lower than for other products in the same product group.

The Ecolabel is a voluntary tool of environmental policy for sustainable development and has been awarded to products since 1992. The system is based on the preventive reduction of product manufacturing and service provision impact at all stages of their life cycle.

Briefly about: Improving soil with compost

An option for improvement of elaborated peat-free soil conditioner formula can be adding composted material. But what is compost?

A mixture of different organic minerals (organic residues, soil organic residues) which are modified by organism action is called compost. It can be stacked, moistened, limed, organic or mineral fertilizers and biological preparations, etc. additives that promote biological processes and decomposition of organic compounds can be added to it. Composting is a human-regulated biological process in which organic matter (also different waste) is converted into humus-like material. Composting not only reduces the amount of waste, but also reduces the use of mineral fertilizers. Good compost improves soil structure and provides plants with the necessary nutrients, it is used to improve soil properties, as a fertilizer, as well as as a substrate in horticulture.
