PEDOLOGICAL AND AGROCHEMICAL STUDY IN THE RADU VODĂ AND LUPȘANU AREA, CĂLĂRAȘI COUNTY, COVERING AN AREA OF 500 HA, WITH THE DEVELOPMENT OF A FERTILIZATION PLAN FOR CROPS

Abstract

This study is the subject of research contract no. 378/04.02.2025, concluded between USAMV in Bucharest and SC LUXCOM SRL, regarding the soil and agrochemical mapping in the Radu Vodă and Lupșanu area, Călărași County, aimed at identifying and characterizing the dominant soil type and developing a fertilization plan for crops.
The pedoclimatic conditions are specific to the plain area (Central Bărăgan) on the interfluve between Ialomița and Mostiștea, with a temperate climate of the Bsax type (Koppen, 1936).
Soil profiles and control surveys were performed in different plots from which soil samples were collected both in natural and disturbed conditions, according to the Guide for field description of soil profiles and specific environmental conditions (Florea and Munteanu, 2009). From each plot, average agrochemical samples were collected according to the INCDPA-PM instructions, these being conditioned in the laboratories of USAMV in Bucharest and analyzed by the company SC Cartare agrochimică SRL.
Based on the results obtained, a fertilization plan was drawn up for the crops, depending on the expected yield, the nutrient reserve in the soil, and the preceding crop, with the entire area being arranged for irrigation (drip and sprinkler).
