Abstract Purpose of Review Continuous replanting land with the same or similar plant species can result in accumulation harmful soil microbes, which lead to crop failure. In this review, we explore influence constant on health short-rotation forestry soil, focusing deleterious microbes and decline beneficial microbes. We also suggest possible practical solutions address problem consider future ...

Intensive management is crucial for optimizing hardwood plantation success, and nitrogen (N) nutrition management is one of the most important practices in intensive management. Because management of short-rotation woody crop plantations is a mixture of row-crop agriculture and plantation forestry, we tested the usefulness of an agronomic budget modified for deciduous perennial trees for estima...

Nacrtak In Italy, short rotation forest has become very popular in recent years, with over 4,000 hectares already planted – almost exclusively with clone poplar. The study models the performance of modified forage harvesters on a range of short-rotation poplar plantations, identifies technical obstacles to the deployment of these machines and suggests solutions that may expand the capability of...

Despite a growing body of research linking bioenergy cultivation to changing patterns of biodiversity, there has been remarkably little interest in how bioenergy plantations affect key ecosystem processes underpinning important ecosystem services. In this study, we compare how the processes of predation by ground arthropods and litter decomposition varied between Short Rotation Coppice (SRC) wi...

The objective of this review is to compare the cost of coppice and longer rotation poplar harvesting technology. Harvesting technology for short rotation poplar has evolved over the years to address both coppice harvest and single-stem harvest systems. Two potential approaches for coppice harvesting are modified forage harvesters and modified mulcher-balers. Both of these systems effectively ha...

As a routine wood source for a pulp mill, recent studies have shown that intensively managed, short-rotation hardwood plantations are not cost effective. The objective of this study was to determine if these plantations may be cost effective as “green” inventory, replacing some portion of high cost remote woodyard inventory. Three southeastern U.S. pulp mills were used as case studies in a net ...

BACKGROUND The speckle tracking echocardiography can benefit to assess the regional myocardial deformations. Although, previous reports suggested no significant change in left ventricular (LV) torsion with aging, there are certain differences in LV rotation at the base and apex. The purpose of this study was to evaluate the change and relationship of LV rotation for torsion with aging in childr...

We study the growth at the golden rotation number ω = ( √ 5 − 1)/2 of the function sequence Pn(ω) = ∏n r=1 |2 sinπrω|. This sequence has been variously studied elsewhere as a skew product of sines, Birkho sum, q-Pochhammer symbol (on the unit circle), and restricted Euler function. In particular we study the Fibonacci decimation of the sequence Pn, namely the sub-sequence Qn = ∣∣∣∏Fn r=1 2 sinπ...

It has been conjectured that there are no homogeneous rotation symmetric bent Boolean functions of degree greater than two. In this paper we begin by proving that sums of short-cycle rotation symmetric bent Boolean functions must contain a specific degree two monomial rotation symmetric Boolean function. We then prove most cases of the conjecture in n=2p, p>2 prime, variables and extend this wo...
