The composition of chernozem cambic size of the intensive apple plantation from Timisoara Didactic small changes in the two years of research (2014-2015) due to the application of fertilizer N, P, K and manure ( that was administered in the fall of 2013). Between rows of trees, soil density has changed greatly compared to that row of trees, this is due to subsidence of the soil due to more pronounced during repeated passes of maintenance and harvesting. Between rows of trees, soil bulk density was significantly higher than the row of trees. The lowest values of soil density in the two years of research, have been found in variant fertilized with manure, both among the trees and between rows of trees at 0-20 m depth, and the highest values if N150P100K50 variant, both among the trees and between rows of fruit at 40-60 cm depth, but these values have not changed much compared to the control. The lowest bulk density values were recorded in the variant fertilized with manure, and the highest values in N100P50K20 variant in the two years of research. Following trecrerii agricultural machinery DA increase greatly. Soil samples were collected before and on the trail passing cars fertilizers administered to ascertain the differences that arise. The fundamental properties of the soil to provide conditions for plant growth, and that the net difference between the rock on account of which formed, called fertility. The fertility of a soil depends directly on the soil physical and chemical properties respectively. Fertility, is a result of the state of training and development of soil, its composition and properties, physical and chemical processes that occur in the soil. Agricultural practice shows that, indeed, production capacity and therefore yields may increase, by certain measures, such as: improved use of machinery and high-tech tools; use of fertilizers, amendments and fighting substances; by performing works of irrigation, drainage, drainage, embankment, prevention and erosion control; by improving labor and human knowledge; by applying the results of scientific research, etc.
