Evaluation of the phytomass source for composite preparation

Journal of Applied Polymer Science, 2012
AbstractThe properties of lignocellulose materials from the trunk and bark of trees, and from agricultural sources were investigated by thermogravimetry (TG) and pyrolysis–gas chromatography/mass spectrometry (Py‐GC/MS). The goal was to learn which of the phytomass sources is the most accessible to dehydration and aldol reactions, and in this way could

Estimating the limits of renewable energy from phytomass

Energy, 2022
Abstract The energy production from phytomass on agricultural and forest lands can be calculated on the basis of the annual production of hydrocarbons (cellulose, starch, sugar, etc.), without needing to take into account the type of phytomass and the mean-weighted specific power production per unit of land area.

Assessment of grassland phytomass with airborne video imagery

Remote Sensing of Environment, 1986
Airborne video imagery was evaluated for assessing phytomass production within grass plots fertilized with five rates of nitrogen. Video imagery was taken with two black-and-white video cameras—one visible light and the other visible/near-infrared light sensitive.

ALLOMETRIC PATTERNS OF PHYTOMASS CHANGES OF SCOTS PINE

Вестник Бурятской государственной сельскохозяйственной академии имени В. Р. Филиппова, 2023
Цель исследования заключалась в выявлении аллометрических закономерностей, описывающих зависимость высоты дерева, фитомассы различных фракций деревьев от диаметра ствола на высоте груди. Исследования проведены в молодых сосняках лишайниковых, брусничных и черничных возрастного периода от 10 до 40 лет Бабаевского лесничества Балтийско-Белозерского ...

Phytomass measurements in Zachariashoek, Kasteelkloof, site 3319CC/1

2022
This is a scanned copy of a document on phytomass measurements, Zachariashoek, Kasteelkloof. The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities

Phytomasse- und Nährstoffverhältnisse Einer Alpinen Rasengesellschaft (Caricetum Firmae)

1976
A plot of the typical alpine meadow community of the Northern Calcareous Alps, the Cariceturn firmae (Altitude 2160m), was investigated with regard to its mean dry substance (TS) values and changes during the growing season (VP) and to its main nutrient (N-, P- and K-) relations.
