| Title : | INFLUENCE OF STRAW ORGANICS ON CHARACTERISTICS OF SOIL FERTILITY AND BIOLOGICAL YIELD CAPACITY (BARLEY CASE STUDY) |
| Abstract : | Monitoring soil productivity is a relevant issue in modern agricultural technologies. A particular interest is taken in evaluating the effect of straw combined with microorganisms and thus used as organics. To collect practical data, in 2012-2014 a microplot experiment was conducted on the territory of the Botanical Garden of Voronezh Agricultural University. The aim of the experiment was to study biological activity of leached chernozem (black earth). For this, straw combined with a special bacteria agent Baikal AM1 was ploughed up in a fallow plot. It was found that annual use of such a combination can increase the organics amount of soil by 1,3 as much. All the variants demonstrate the significant increase in urease, while catalase activity varied only slightly. The variants with straw processed with microorganisms show the increase in phosphotase and invertase. Analysis of the total microorganisms’ amount grown in SАА (starch-and-ammonia agar) and МPА (meat-and-peptone agar) reveals the transformation of soil organics. Both the lowest and highest figures were found across the tested plots. The plots with both straw and microorganisms demonstrated the highest productivity, grain content and ear output, thus showing better prospects for yield capacity. In the short term, this study is supposed to launch forecasting both soil productivity and yield capacity in different regions of Russia. |
