Organic fertilizer

Organic fertilizer formed by decomposition of dead organic matter constitutes a series of solutions aiming at the improvement of soil fertility and counteracting its depletion. In agriculture, the most commonly used organic fertilizer is either manure or compost....

Growth stimulant

Growth stimulants are biologically active substances that determine the growth of plants. Growth stimulants available on the market are either chemical or natural. The advantage of the latter type lies in the fact that they are very plant-friendly and that there is no...

Lumpy structure

Lumpy structure – compacted soil particles which form aggregates of a lower or greater volume with perforations between them. These perforations supply the root system of plants with oxygen, water and nutritional substances dissolved in it. The free spaces increase...

Cation exchange

Cation exchange - a chemical process in which a particular number of cations, contained in aqueous solution, is transferred into soil. It is connected with the simultaneous transfer of an equivalent quantity of cations from soil to aqueous solution. The group of ions...

Soil colloids

Soil colloids are a system of particles, smaller than 0.002 mm, in a dispersion system. They are the smallest fraction of particles. They include hydrated iron and aluminum oxides, clay minerals, amorphous minerals, clay-humus complexes and humus itself. Research...

Humic acid salts

Humic acid salts, or humins, are humic acids bound with metal ions. Humic acid is one of the fractions of humus. It is characterized by its color which can be dark brown to black. In the process of soil extraction, it can be dissolved in alkalis. Humic acids are...

Fulvic acids

Fulvic acids are a fraction of humus that is distinguished by its yellow or yellowish brown color. They are made of aromatic rings which consist of functional groups - phenolic and carboxylic. Similarly to humic acids, they have side chains. More importantly, the...

Humic acids

Humic acids are complex chemical compounds which are created by the decomposition of dead organic matter and which are found in soil humus. Their molecules are made of aromatic carbon rings, consisting of functional groups – carboxyl, hydroxyl, methoxyl and alkyl...
