IMPACTS OF FERTILIZER APPLICATION ON SOIL PROPERTIES AT KAHAROLE UPAZILA OF DINAJPUR DISTRICT IN BANGLADESH
Abstract: The study was
conducted to investigate the impacts of fertilizer application on soil
properties in Kaharole upazila of Dinajpur district in Bangladesh. Samples were
collected to analyze the variation of soil nutrients in three cropping seasons:
season-1 (March-April, 2013), season-2 (August-September, 2013) and season-3
(January-February, 2014). In each season 10 samples, 6 from conventionally
cultivated soil (CCS) and 4 from organic fertilized soil (OFS), were collected
from 10 randomly selected sampling points. The study observed acidic soil pH in
all three cropping seasons, while soil pH was decreasing gradually with
fertilizer application. The results of the study clearly depicted that all the
soil nutrient contents and OM decreased with the application of fertilizers in
different cropping seasons except Zn and Fe. The OFS contains relatively higher
amount of OM and essential nutrients than CCS except Fe and Zn. The study shows
that the continuous application of fertilizer in agricultural lands reduces
soil fertility evolving nutrient deficiency in the soil; resulting in reduced
crop productivity.
