In this article we will discuss about:- 1. Classification of Soil Water 2. Sources of Soil Water 3. Movement of Water in Soils 4. Losses. Classification of Soil Water: Soil water plays very important role in the growth and development of plants. Plant absorbs nutrients from the soil in the form of soil solution. The soil water containing nutrient ions [...]
Flow of water in the soil is complex because of various states and direction in which water flows and because of the forces that cause it to flow. Water flows downwards due to gravity. It moves in small pores due to capillarity because of adhesive and cohesive forces. Because of heat, it vapourises and diffuses through soil air. The rate [...]
The following article will guide you about how to measure soil moisture by obtaining direct and indirect methods. Soil moisture content is, normally, given as a dimensionless ratio of two masses or two volumes. When soil moisture content, given as dimensionless ratio, is multiplied by 100, the value becomes a percentage on mass or volume basis. Determination of soil moisture [...]
