Sustainable forest management requires accurate biometric tools to estimate site quality. This is particularly relevant for prescribing adequate silvicultural treatments of planning. The aim this research was incorporate topographic and climatic variables into dominant height growth models patula pine stands improve the estimation stand productivity. Three generalized algebraic difference appro...

Estimating tree volume components is an essential element in sustainable forest management. Compatible taper and merchantable outside-bark systems based on ratio models were globally fitted to four pine species (reduced models) with the aim select best reduced model fit it dummy variables additive effects using Pinus pseudostrobus Lindl as a base species. The study was carried out northern moun...

Diplodia pinea, an opportunistic and latent pathogen, can significantly affect Pinus productivity worldwide. Despite being studied in South Africa for almost 100 years, the source of D. pinea inoculum responsible for seedling infection is unknown. The aim of this study was to determine the role of seed in vertical transmission of D. pinea and to investigate sources of inoculum leading to horizo...

In this work, biochar (BC), a co-product of the fixed bed gasification process Pinus patula wood pellets (PL) and chips (CH), was characterized as soil amendment. The physicochemical properties mineral content pellet’s (PL-BC) (CH-BC) were analyzed following NTC5167 Colombian technical standard. BET surface area values BCs 367,33 m2/g 233,56 for PL-BC CH-BC, respectively, pore volume 0,20 cm3...
