SPATIAL AND TEMPORAL CHANGES OF SOIL ORGANIC CARBON AFTER IMPROPER APPLICATION OF FARMYARD MANURE – ON FARM STUDY
Keywords:
Farmyard manure, quality of manure application, spatial variability, organic matter, soil profile, drip irrigationAbstract
Study of spatial and temporal variation of soil organic carbon depending on it distribution on field and in soil profile by drip irrigation on sandy soil. A network of sampling points was created using GPS equipment. Subsequent processing of obtained results using geostatistical methods was effectuated. Kriging maps with the distribution of organic carbon content were created. Immediately after manure application, in the abundantly fertilized part of the field, organic carbon content decreased down soil profile as follows 2.12%, 0.55% and 0.42% every 30 centimeters. Two years after a significant movement down soil profile of soil organic carbon was observed – 1.69%, 1.55% and 1.47% respectively. In a poorly fertilized part of the field organic carbon content did not changed.
