Upload NowProductivity of crops depends on adequate supply of nutrients from the soil. Generally, the quantity of nutrients removed by the crop (nutrient uptake) is much greater than the quantity of applied nutrients resulting in poor fertility status of soils. Hence, to improve the fertility status of soil and to sustain the productivity of crops, soil […]

In this article we will discuss about how to measure soil moisture content. Direct Measurement of Soil Moisture Content in the Soil: (a) Gravimetric Method: Soil is dried at 105-110 °C and before and after the drying, weight of the soil is taken. And from the difference, moisture percentage is calculated. (b) Infra-Red Moisture Balance […]
How to Determine the Relative Density of Soils ?
Article shared by : 
Relative density of cohesionless soils is defined as the ratio of the difference between the void ratio of a cohesion- less soil in the loosest state and in-situ void ratio to the difference between its void ratios in the loosest and the densest states. Thus relative density (Dr), also called density index (Id), is defined […]
