The formation of humus profiles in forest ecosystems depends on the soil and plant cover types, and on the flux of falling debris into the soil. The transformation of "fresh organic matter" into humus is mainly performed by soil organisms. Therefore the species composition and abundance of living organisms in humus covers are good indicators in the evaluation of ecosystems functional efficienc ...

The aim of this paper is to present the microorganisms and their activities and soil bulk density. It is a fact that both have a great impact on soil fertility and its health status. Among the microorganisms in soil, the bacteria and fungi are the most important ones for potato cultivation; the bacteria living on the plant roots serve to uphold the nutrient intake of plants. Our previous resea ...

The trials were carried out in 2012 and 2013 at the Estonian University of Life Sciences. Total yield, marketable yield, number of tubers per plant, average weight of tubers, tuber starch content was studied in cultivar 'Ants' (medium late) and 'Laura' (medium early). Following treatments were used: untreated control (T0) Seed tubers were planted directly from storage house (storage temperatur ...

Molecular methods are currently available to detect parasitic DNA in soil, but do not replace the need for direct parasitological methods that can identify the extent of contamination. This report describes an inexpensive and fast flotation method for retrieving Eimeria oocysts from soil that requires few tools. Soil samples were experimentally contaminated with 50,000 E. bovis oocysts and com ...

The impact of using humic substance for growing potato on quality indicators of tubers. Humic preparations are concentrated and economical form of organic matter which can relieve humus depletion caused by conventional fertilization methods. The trials were carried out in 2012 and 2013 at the Estonian University of Life Sciences in Estonia. The yield of tubers and starch, and commercial yield ...

Occupational accidents in agriculture are a problem all over the world. The costs of accidents are high to the employer and to the national economy as a whole. Work-related ill-health and injury is costing the European Union 3.3% of its GDP. In Estonia, the estimates of the costs of work accidents (WA) in 2012 showed €2.4 billion per year and due to permanent lost workability €25 billion costs ...
