In the researched area, located on the terrace of southwestern Alexandria, soil fertility (evaluated by such indicators as humus content, biological activity of the soil, ecological index, production level) showed that the amount of carbon and nitrogen in the soil decreased by two times in the last 100 years, especially due to a defective management of soil tillage and plant nutrition. In order to restore soil balance and to improve the relations between plants and soil, between 2004 and 2011, intensive and continuous research was carried out on the chernozem of the Burnaz Plain, aiming at: the use of a tillage conservation system, crop rotation with ameliorative plants, residual biomass (4-5 tonnes/ha) and several soil bioactivators in the recovery of the physical, biological and ecological parameters, as well as fertility and grain production increase. Thus, flows were recovered on soil profile, the quantity of Humus C in soil increased by 1.9 times, the biological activity of soil increased by 2-2.5 times, the ecological index by 1.8 times, the soil capacity to retain, preserve and dispose the water to the plants grew three times and also the production level of premium high quality grains increased by about 2 times.
