Relationship between compaction levels (bulk density) and chemical properties of different textured soil

Abstract

The investigation entitled "Study of relationship between compaction level (bulk density) and chemical properties of different textured soil" was carried out using various research materials and analytical techniques during 2017-18 at

Impact of cover crop and mulching on soil physical properties and soil nutrients in a citrus orchard

“…According to Belayneh, Yirgu & Tsegaye (2019) , high BD negatively affected soil nutrients due to decreased soil biological and biochemical processes, resulting in reduced soil fertility. A similar result has been reported by Singh et al (2020) . They indicated a negative correlation between BD and soil nutrients.…”

The Influence of Slope Gradient on Termite Assemblages and Soil Physico-Chemical Properties in Koudi Secondary Forest Patches of the Central Region of Cameroon

“…Consequently, bulk density was positively correlated to pH-water. This may be explained by the soil compaction decreases porosity and reduction of organic matter in steeper slope [40]. Conversely, bulk density was negatively correlated to soil organic matter, confirming some researches that revealed the importance of organic carbon in soil aggregation, which decreases bulk density [41].…”

Restoring soil nutrient stocks using local inputs, tillage and sorghum-green gram intercropping strategies for drylands in Eastern Kenya

“…This is because conventional tillage can result in the loss of soil organic matter and nutrients, including micro-nutrients. Conventional tillage systems can lead to compaction of soils, resulting to increased soil bulk density which can reduce soil aeration and water infiltration, limiting zinc availability [ 37 ]. Singh et al [ 37 ] reported significant and strong negative correlations between soil bulk density and soil zinc availability (r = - 0.925–0.929) under loamy sand, sandy loam and sandy clay loam soils.…”

Singh et al [ 37 ] reported significant and strong negative correlations between soil bulk density and soil zinc availability (r = - 0.925–0.929) under loamy sand, sandy loam and sandy clay loam soils. In addition, high negative correlations were also detected between soil bulk density and soil Iron (r = −0.931 -0.981) for the same soil types [ 37 ].…”

Tied ridging with organic soil input integration can improve soil zinc availability through reduced soil erosion, conservation of soil organic matter, soil moisture, improved soil biological properties and reduction of the soil bulk density, which can improve soil micronutrient fertility.…”
