Direct seeding

When practicing direct seeding on forest land there are practical recommendations considering among others Norway spruce (Picea abies (L.) Karst.) , Scots pine (Pinus sylvestris L. ), birch, beech (Fagus sylvatica L.) and oak in relation to the target species. There are, however, few recommendations available for seeding on farmland, although the factors associated with successful establishment are the same […]

In the semi-arid agricultural areas of the world, soil salinization is closely linked to the extensive use of artificial irrigation, which in combination with extended dry seasons, very quickly turns formerly productive areas practically into deserts. In the future, this effect will even increase due to the high demand of water from other non agriculture sectors (i. e. industry, overpopulated […]

Effects of environment on vegetables

Costa & Leal (2009) observed that in hydroponic production of lettuce, variety Vera, in three greenhouses, one without evaporative cooling and CO2 injection, another with injection of CO2 and without evaporative cooling and a third, with CO2 injection and evaporative cooling (acclimatized), the environment with evaporative cooling and CO2 injection promoted the best development of plants with larger leaves.

Chemicals, kefir culture and culture medium

Daily kefir grain increase mass was studied using fresh HTP whole fat cow’s milk (Ljubljanske mlekarne d. d.) as a culture medium. Its chemical composition is 3.2 % proteins, 4.6 % carbohydrates, 3.5 % fat and 0.13 % calcium. 3D-(+) Glucose anhydrous (Fluka) was obtained from commercial sources. Kefir grains, used as inocolum in this study, originate from Caucasian Mountain […]

Determination of wheat grain quality

Protein (N x 5.70) content was determined by Kjeldahl method by automatic nitrogen analyzer (methodology ISO 1871:1975). Falling number was determined according to ISO 3093:2004. Gluten content was determined by Glutomatic according to ISO 7495:1990. Sedimentation index of wheat flour (Zeleny sedimentation test) was determined according ISO 5529:1992. Determination of bulk density, called "mass per hectoliter" was performed according to […]

Main anthropogenic sources of toxic element pollution and their health effects

Environmental pollution, strictly interconnected to industrial spread, started in the most advanced countries. It is now diffused all over the world with a significant predominance in the emerging industrialized states. Varying factors contribute to the location of a large number of "potential polluting" industries in these countries due to the quite recent industrialization: source of raw materials (mines, forests, .
