Cuttings Growth Response of Dalbergia Sissoo (Shisham) to Soil Compaction Stress

Abstract

Because of the intensive use of machinery, soil compaction is a serious concern for soil management authorities worldwide. The use of heavy machinery to perform forestry activities such as logging has increased during the last few decades, which influences the soil ecosystem by inducing soil compaction. The main objective of this study was to observe the morphological growth response of Dalbergia sissoo at different compaction levels. Different morphological parameters were recorded including girth/diameter, shoot length, root length, shoot weight, root weight, shoot dry weight, root dry weight, root-shoot ratio, moisture content availability, and biomass production to analyze the effect of soil compaction. As the compaction level increased, the shoot length, root length, root weight to shoot weight ratio, and biomass production decreased. Simultaneously, the bulk density of soil increased as the compaction level increased. Soil compaction produced an overall negative effect on the growth of D. sissoo. Different levels of soil compaction significantly affected the physical growth parameters of the plant and reduced growth as soil compaction increased. Based on the results, the plantation of D. sissoo without compaction can be a viable option to obtain good quality timber.

Influence of Intraspecific Competition Stress on Soil Fungal Diversity and Composition in Relation to Tree Growth and Soil Fertility in Sub-Tropical Soils under Chinese Fir Monoculture

“…Plantation productivity, stand growth, canopy structure, and soil fertility all are influenced by various forest management practices, such as stand density and spacing [7][8][9], stand structure [10], species genotype [11], use of cutting [12], seed germination methods [13,14], use of inorganic and organic amendments [15], and planting pattern [16]. Among them, plantation stand density is a crucial subject in silvicultural techniques.…”

Unraveling the Influence of Land-Use Change on δ13C, δ15N, and Soil Nutritional Status in Coniferous, Broadleaved, and Mixed Forests in Southern China: A Field Investigation

“…These impacts are likely to have significant consequences for belowground communities [ 1 ]. Similarly, different land uses cannot directly affect soil fertility, but it can influence through indirect effects such as organic/inorganic amendments [ 66 , 67 , 68 ], various stresses for plant and nutrient availability [ 69 , 70 ], different planting materials [ 71 , 72 ], and atmospheric deposition levels and turnover rates [ 73 ].…”
