ASSESSMENT OF THE PRODUCTIVE CAPACITY OF AGRICULTURAL LANDS FOR THEIR SUSTAINABLE USE

The purpose of the paper was to assess the production capacity of the lands in Periam, Timis County, in wheat, barley, corn, and sunflower. We chose 17 more important and better determining indicators and, based on them, we established, for each crop, the credit ratings, after which we classified the soils in the studied area into fertility classes. In accordance with the methodology for developing pedological studies, the degree of suitability was determined for each of the four crops: 91.73% of the area of this locality is represented by agricultural land, of which arable land represents 79.22%. and 0.41% is forested land. Following the evaluation of arable land (4,663 ha), it was found that 45.38% fall into the first class, 33.63% in Class II, 20.10% in Class III, and 0.89% in Class IV, with an average grade of 75. This makes these lands highly productive. As a general conclusion, each farmer should periodically evaluate the fertility of the farm soils, make a balance of the nutrient requirements for each crop by considering the plants' requirements according to the vegetation phase, the technology applied, the local soil land climate conditions based on realistic forecasts. In this way, a series of costs with fertilizers and soil work are reduced, the excess is eliminated, and the deficiency of nutrients is corrected, the recommended doses are fractionated and applied differently depending on the needs of the plant, the humidity, the reaction and the texture of the soil. Following the results obtained, it appears that these lands have a high production capacity.
