Abstract

The field experiment was conducted at the Experimental Station of Vytautas Magnus University Agriculture Academy in 2020. Soil - (Calc(ar)i-Endohypogleyic Luvisol) (LVg-n-w-cc). The spring wheat ‘Wicki’ crop cultivated in two-factor field experiment. Factor A – tillage technology: 1) zero tillage; 2) vertical tillage. Factor B – Biological preparations and their mixtures. Experimental treatments – 1) N8 - 8 kg of compensatory nitrogen to 1 t of straw, without biological preparations; 2) Ruinex 1 l ha-1; 3) Penergetic k 0.2 l ha-1; 4) Azofix 1 l ha-1; 5) Ruinex 1 l ha-1 + Penergetic k 0.2 l ha-1; 6) Ruinex 1 l ha-1 + Azofix 0.5 l ha-1; 7) Penergetic k 0.2 l ha-1 + Azofix 1 l ha-1; 8) Ruinex 1 l ha-1 + Penergetic k 0.2 l ha-1 + Azofix 0.5 l ha-1. The experimental fields of 60 m2 were arranged randomized in 4 repetitions. The experiment aimed to evaluate soil properties using different biological products and compare the effects of biological preparations using zero tillage and vertical tillage.

During the investigation was found that the use of biological preparations and their mixtures without tillage (zero tillage) has increased SOC from 1.7% up to 9.4 % in soil compared to the use of compensatory nitrogen, except the bio-preparation Azofix. In the study, the ratio of carbon to nitrogen ranged from 11.3:1 to 12.4:1. The highest content of water-soluble carbon was found i

In the study, the ratio of carbon to nitrogen ranged from 11.3:1 to 12.4:1. The highest content of water-soluble carbon was found in the vertical tillage system using the bio-preparation mixture Ruinex + Penergetic k (0.248 g kg-1). The most of the hummus was accumulated in the soil in which the mixture of biological preparations Ruinex + Penergetic k + Azofix was used (2.20% zero tillage, 2.18% vertical tillage).
