Investigation of soil properties and nutrients in agricultural practiced land in Tangail, Bangladesh
Int. J. Agril. Res. Innov. Tech. 10(2): 84-90, December , 2020
The study investigated on soil nutrients in agriculture practiced high, medium high, medium low and low land at Kalihati upazila of Tangail district during October 2017 to June 2018. Thirty soil samples were collected from different land types at the study area and analyzed at Soil Resource Development Institute (SRDI) to determine soil nutrient status. The soil parameters under investigation included pH, organic matter (OM), total nitrogen (N), available phosphorus (P), available zinc (Zn), available iron (Fe), available manganese (Mn), available boron (B), exchangeable potassium (K), exchangeable calcium (Ca) and exchangeable magnesium (Mg). Results indicated that many of the soil nutrient levels decreased such as pH (5.63 to 6.40), P (3.50 to 23.20 μg g-1), Zn (3.27 to 3.60 μg g-1), Mn (21.12 to 57.90 μg g-1), B (0.17 to 0.60 μg g-1), K (0.18 to 0.30 meq 100g-1) and Ca (5.75 to 9.10 meq 100g-1). On the contrary, the average content of OM (2.30 to 1.40%), Fe (248.22 to 161.10 μg g-1) and Mg (2.07 to 1.80 meq 100g-1) were increased. Total N content status did not change much (0.12%). Soil nutrients like those that available Zn, Fe, Mn and Mg contents were found above optimum level (very high) but OM and N status found below optimum level (low, very low and medium). Nutrient concentrations below optimum levels may limit crop yield. Updated knowledge about soil nutrient status needs to be provided for the farmers so that they can use necessary amount of fertilizers and avoid applying excess amount of fertilizers.
Physico-Chemical Analysis of Soil from Kadegaon Tehsil (Sangli District
Soil analysis is a valuable tool for farm as it determines the inputs required for efficient and economic production. A proper soil test will help ensure the application of enough fertilizer to meet the requirements of the crop while taking advantage of the nutrients already present in the soil. The aims of soil analysis are: To determine the level of availability of nutrients or the need for its introduction. To predict the increase in yields and profitability of fertilization (poor soils do not always provide yield increase due to fertilization because of possible limiting factors) and to save money and conserve energy by applying only the amount of fertilizer needed. In the present study it was preferred to investigate the soil samples for its physico-chemical analysis of some parameters. Nine representative samples were collected and analyzed for its pH, EC, organic carbon, phosphorous, manganese, K2O, zinc, copper, calcium bicarbonate.

The present research was designed to study and compare the physio-chemical properties of two different districts of Khyber Pakhtunkhwa, Pakistan i.e. Peshawar and Swabi. Ten soil samples from each district were collected at a depth of 10-15 cm from the selected sites and were analyzed for the different physical and chemical parameters. According to t-test, the Electrical Conductivity (EC), pH and Soil Organic Matter (SOM) were significant while the results of moisture content and bulk density were not significant. The results showed that there was a very little difference in the properties of soil of both districts. This change occurs due to the change in topography, weathering processes, climate, human activities. The soil of both districts is loam consisting equal amount of sand and silt and having less amount of clay which is good for farming. The bulk density of Swabi district soil is slightly higher than Peshawar district soil because of a little more sand content. The pH of soil of both districts is neutral which is suitable for agriculture. Moisture content of Swabi is less than Peshawar. As electrical conductivity may also depend upon texture, moisture and salts so the EC of Peshawar district is a little bit high than Swabi district. It was concluded that the properties of soil which were taken in account are depended on each other and affect the soil fertility and crop productivity and habitat sustainability, and the differences between the properties of both districts are due to agricultural practices, irrigation system, and use of fertilizers or may be due to some natural conditions. As soil is part of our ecosystem it is recommended that artificial fertilizers should be used in a proper way and in proper amount as it is not good for health. Crop rotation and good irrigation should be used in a proper manner in order to maintain the soil physio-chemical properties in good condition.
