WebApr 24, 2013 · The impact of higher moisture content on organic matter accumulation Throughout this article moisture contents have been referred to as a percentage figures. If we estimate 40-50% of the soil profile is solid mass (silt, sand, clay and organic matter), the rest is made up of water (moisture) or air to varying extents. WebJun 30, 2016 · Studies show that the performance of soil water content monitoring (SWCM) sensors is affected by soil physical and chemical properties. However, the effect of organic matter on SWCM sensor responses remains less understood. Therefore, the objectives of this study are to (i) assess the effect of organic matter on the accuracy and precision of …
