PROSPECTS OF USING THE LOCAL ORGANIC WASTE IN THE AGRICULTURE OF THE REPUBLIC OF MOLDOVA

Written by Tamara LEAH

Land use in agriculture of Moldova led to the acceleration of decomposition of accumulated organic matter, and therefore to the loss of carbon. High carbon losses from agricultural soils become a problem with appropriately sized, as this phenomenon affects not only agriculture, but accelerates the degradation of the environment. In the last 20 years, the amount of organic fertilizers decreased 60 times and consists 0.01 t/ha, the area of alfalfa has decreased 4-5 times, on the large areas the crop residues are burned. As a source of remediation the soil organic matter can serve local organic waste: manure of rural households, sewage sludge, wine lees, vinasse, cereal waste, fermented straw etc. Application of organic waste in agricultural practice for soil fertilization contributes to the maintenance a balanced circuit of carbon and nutrients. Each tone of organic waste applied as fertilizer supplements humus reserve with 85-100 kg/ha, with nitrogen 8-9 kg/ha, stimulates increasing production potential and improves the soil fertility. The effect of organogenic waste application is expected for a period of 4-5 years. Along with increasing the soil fertility and reducing the negative impact on the environment, applied waste can provide, depending on the production schedule and application specific, income from 1 tone of fertilizer: 89-928 MDL, with a recovery period of expenses - 1-3 years.
