Abstract

Since large areas of field crops are cultivated in Romania with cereals and legumes, corn crops find a favorable environment in almost all regions of the country for development and the production of grain yields and record green mass.

The purpose of this paper is to explain the importance of knowing the physical, hydro physical and chemical properties of the soils studied in order to obtain the desired productions. The researches take place in the commune of Izbiceni Olt County, SC AGROPRIM SRL, where the amendments with CaCO3 and mineral fertilization with NPK were applied in different quantities, and the effect on the agrochemical properties of soil with effect on production was applied.

Soil fertility and changes occurring due to the application of CaCO3 and NPK and the production of corn grain are also being studied. Due to the application of calcium-based modifications and the application of variable doses of NPK, an improved acid reaction of the soil and a better supply of plants with fertilizing elements and water is achieved.

 Analyzing the interaction between the three factors, it can be concluded that all three have contributed positively to the production of grain maize compared to the unmodified and untreated control. From the results obtained, it is clearly evident the necessity of chemical and mineral fertilization, the treatment of slightly acidic soil with amendments before the establishment of the culture, in order to obtain planned results.
