SEWAGE SLUDGE INFLUENCE UPON SOIL FERTILITY IMPROVEMENT
AbstractSoil like culture is part of the environment in which the fertility momentary expression through a specific energy balance. On the hand, permanent reactions occur between soil phases (solid, liquid, gas), with release of energy, on the other hand the biological activity of plants (nutrient uptake, growth and development) makes various forms of energy and stored it. Sludge waste or processed or composted, representing organic fertilizer can contribute to amplification reactions due to the wealth of cultural soil organic matter (OM), commonly around 25 %. By using it in different doses (0-50 t.ha-1) improved soil carbon (C) as the main chemical element of OM and humus, with macro- and microelements. Due to improved soil total organic carbon (TOC) crops like maize, wheat, soybean, have formed useful production (grains) in addition.
