Growth of forest stands as analogue of production process in economic systems: E2E-model [PDF]

Сибирский лесной журнал, 2015
An economic-ecological model (E2E-model) is proposed to describe the growth of plants. The process of growth of forest stand phytomass is considered within the E2E model as an analogue of the production process in economics.

REMOTE SENSING METHODS FOR PHYTOMASS ESTIMATION AND MAPPING OF TUNDRA VEGETATION

Geography, Environment, Sustainability, 2010
Mapping of above-ground phytomass provides a baseline for monitoring climate-induced changes, especially in the northern regions. This is important for practical applications, such as assessing quality of pastures and defining reindeer migration routes ...

Change in the general aboveground phytomass as a basis for modeling dynamics of recovery of vegetative cover

Biosystems Diversity
Our study was focused on changes in the general aboveground phytomass during restoration of the vegetative cover. The objective was to analyze changes in the aboveground phytomass as an indicator of autogenic ecosystem dynamics.

Communities of Phragmites australis (Cav.) Trin.ex Steud. in the fluvial terrace of Lower Danube: their diversity and structure of the above-ground phytomass

Biologica Nyssana, 2017
Determination of stocks of aboveground phytomass of reed communities in Bulgaria is not well studied yet. This survey is the most detailed study on the stocks of the aboveground phytomass of the reed communities (Phragmites australis (Cav.) Trin.

The influence of mineral nutrition and humic acids on the intensity of photosynthesis, as well as the yield and quality of seeds, roots, and aboveground phytomass of milk thistle Silybum marianum (L.) Gaertn. in marginal growing conditions

European Pharmaceutical Journal, 2022
Milk thistle Silybum marianum (L.) Gaertn. is one of the most researched medicinal plants, but at the same time it belongs to crops with wide industry potential whose growth requirements for marginal agroecological conditions or the response to agronomic

Root system size of alfalfa varieties under different plant densities

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2012
The field experiment was established from pre-grown alfalfa sprouts in 2008. In 2009 and 2010, the harvest was carried out. The yield and the root size system (RSS) were evaluated in the total of five cuts.

Models to estimate phytomass accumulation of hydroponic lettuce [PDF]

Scientia Agricola, 2004
The protected and hydroponics cultivation are increasing in Brazil, demanding a better knowledge of crop performance in this environment. Plant dry matter accumulation as a function of solar radiation, temperature, relative humidity and other weather parameters in greenhouse is different when compared with field cultivation.

Artificial Neural Network Modeling of High Arctic Phytomass Using Synthetic Aperture Radar and Multispectral Data

Remote Sensing, 2014
Vegetation in the Arctic is often sparse, spatially heterogeneous, and difficult to model. Synthetic Aperture Radar (SAR) has shown some promise in above-ground phytomass estimation at sub-arctic latitudes, but the utility of this type of data is not ...
