ECONOMIC EFFICIENCY OF MAIN SOIL TYPES FROM WEST REGION OF ROMANIA FOR VARIOUS AGRICULTURAL CROPS

摘要

This paper represents an economic study of the main soil types in West region of Romania for various agricultural crops. Studying the economic efficiency of soil is important because according to it we can draw conclusions about the effectiveness and profitability of crops. Knowing bonitary marks we could find natural production potential of soils for wheat, corn, and sun-flower crops. Economic comparison was obtained by multiplying production by the price/kg practiced in the summer of 2016. In this way we can see on one side which is more profitable crops listed and, on the other hand, if we get the best return on the type of soil that culture. We can also draw conclusions about the profitability of different crops established on soil types studied. In this work we were studied five different soil types located in the western part of Romania. The soil analyses were made on Laboratory from Soil Science Department from Faculty of Agriculture on Timisoara. The obtained results were compared with the Romanian Pedological Studies Elaborating Methodology, 1987. The conditional evaluation of land for natural conditions, each of the above indicators involved in determining the mark of evaluation of evaluation by a coefficient which varies between 0 and 1 as that is totally bad ownership or usage or optimal requirements of the plant considered. Note the uses of evaluation and culture product obtained by multiplying by 100 coefficients of the 17 indicators directly involved in establishing evaluation notes: Y=(x1,x2,x3…..xl7) × 100, where: K-soil evaluation mark;x1, x2, x3, x17 = coefficients value (17 indicators).
