STUDY CONCERNING INFLUENCE OF MANURE AND GREEN MANURE ON MAIN PHYSICAL PROPERTIES OF ERODED SOILS FROM NORTH-WESTERN PART OF ROMANIA
Journal Title: Natural Resources and Sustainable Development - Year 2016, Vol 6, Issue 1
Abstract
The researches efectuated at Agricultural Research and Development Station Oradea in an experience set in 1999 highlited the influence of six types of green manure, pure culture and mixed, and 2 doses of manure on macro-structural hidrostability, bulk density, porosity, strength pentetration and hydraulic conductivity, specific physical indices determinants in achieving favorable conditions for growing of crops.In all variants organic fertilized the compaction degree decreasing, bulk density values being 2.1% - 10.8% lower than in the unfertilized variant. The biggest differences were registered in variants with manure and in variants with mixture green manure bulk density values were lower than in variants with pure green manure crop. As a result, total porsity values increased in all variants organically fertilized. Mixture of green manure determined the obtaining of better values of hydraulic conductivity compared with green manure pure culture.
