Opis:
Chemical fertilizer use is highly increasing in farming activity, and the process has a significant impact on soil quality and pH which is the measurement of the acidity or alkalinity. Therefore, soil pH is the main variable because it regulates plant nutrition availability by controlling the chemical forms of various nutrients in agricultural activity. This research aims to find out the excessive use of chemical fertilizers & dynamic soil pH on agricultural land. The primary data had collected by using questionnaires, interviews, Focus Group Discussion (FGD) and soil testing. For the soil testing experiment, simple random sampling method was used to collect the sample in 11 agricultural continents using GPS technology to identify the land location and 22 soil samples were collected based on pre and post applied chemical fertilizer stage. In order to pH value were tested from the collected soil samples. Accordingly, the data were analyzed by ArcGIS 10.3 using the IDW technique. Therefore, the results find out the condition of soil quality during the pre-chemical fertilization, 9% of the land found to be slightly acidic, 27% of the land with neutral soil structure and 15% of the land with salinity soil structure. During the post-chemical fertilization, 9% of the land was found to be moderately acidic, 41% of the soil was found to be strongly acidic, 32% of the soil highly acidic and 18% of the land be moderately pH. The result of the study shown, chemical fertilizers use highly impact on soil quality and agricultural land productivity.

Opis:
A field experiment was carried out with two varieties of rice (BR 11 and BRRI dhan 31) during Transplanted Aman season of 2018 in K. bearing deep grey terrace soil of Madhupur tract (AEZ 28) under Bangladesh Rice Research Institute (BRRI), Joydebpur. Gazipur. The objective of the study was to know the effect of NPKSZn on the growth and yield of BR 11 and BRRI dhan 31. There were ten treatment combinations with three replications. The treatments were complete (+NPKSZn), reverse complete (-NPKSZn), +N (+PKSZn), -N (+PKSZn), +P (+NKSZn), -P (+NKSZn), +K (+NPSZn) and -K (+NPSZn). The parameters under study were dry matter production, contents and uptake of N, P, K, S and Zn at active and maximum tillering stages, panicle number m’ and grain yield in both the varieties. All the parameters were positively influenced by the treatments under study. Growth and yield of both the varieties were largely affected by the missing nutrient treatment. The highest performance was found with the complete and reverse control treatments whereas the lowest was found with missing element treatments and of course, with control. BR 11 was found to be a better variety than BRRI dhan 31 in respect of yield and yield contributing characters under the treatments. It was also observed that recently fertilized reverse control plot behaved statistically the same as the long term fertilized complete treatment plot. Yield of rice was positively related to K uptake in both the varieties.

Opis:
The world we live in has witnessed some drastic environmental imbalance in recent times. These imbalances have threatened sustainable development- which is the ultimate goal of man-environment relationship. This paper reviews the causes and effects of climate change on man and his environment with a view to using science education to solve the problems posed by climate change. Literature shows that climate change results mainly from human activities such as rapid deforestation for agricultural and industrial purposes, carbon dioxide emission from fossil fuel burning, carbon dioxide emission from burning gasoline for transportation, usage of chemical fertilizers on croplands and methane emission from animals, agriculture and arctic sea beds. The consequences of these activities include global warming, ozone layer depletion, greenhouse effect, rising sea level and acid rain. It is recommended here that the whole educational process be re-packaged to emphasize science education as a panacea for sustainable development. The argument here is that the educational institutions are the best media for the inculcation of proper morals and values. It is also recommended that teacher education programmes should allocate more funds to research in, and teaching of science in schools.
