Soil Compaction on Forest Plantations following Cattle Use
Grazing cattle on forest plantations in the interior of British Columbia is a common practice. Soil compaction can occur following cattle use, although this may vary with stocking rate, vegetation type and age, soil type, soil water content, and climate. Several studies have shown that increased soil compaction can have a negative impact on growth of young tree seedlings and on productivity in ...
متن کاملrole of deforestation on spatial variability of soil nutrients in a hyrcanian forest
studying forest degradation through evaluation of soil nutrient concentrations, which reveals soil functioning within the ecosystem, is necessary for sustainable management of land resources. this research was conducted to understand the changes of soil nutrient, resulting from exploitive management using some soil features and their spatial pattern. in the mid-summer of 2014, two sites were se...
متن کاملبررسی آثار بهره برداری بر زادآوری و فشردگی خاک جنگل در سیستم چوبکشی زمینی (مطالعه موردی جنگل اسالم استان گیلان)
Forest future depends on forest stands regeneration. Soil is one of the principal capitals in the forest area. It is important to minimize damages to the forest ecosystem during logging operation. In forestry and forest management, it is significant to know the effect of forest logging damages on regeneration, sapling and soil compaction. This study was carried out in Asalem Beech forest area, ...
متن کاملConceptual Model for Predicting Forest Productivity Losses from Soil Compaction
A simple, conceptual model for predicting forest productivity losses from soil compaction is presented. Information regarding each component of the model is summarized. Once compacted, most forest soils in the Pacific Northwest are expected to remain compacted and forest growth affected for several decades. Elements within the model which managers are able to manipulate to influence the amount ...
