Agrotool — A system for crop simulation

Abstract

A system for simulation of crop dynamics is described. It includes a dynamic crop model for several cultures and a model shell. The model permits to simulale crop dynamics on the second level of plant productivity. The model shell serves for organization and implementation of series of computer experiments in dialogue regime. As it is known, soil and climatic conditions in the majority of Russia's regions differ from that in West Europe in a principal way. It especially concerns the continental Russia regions where deep droughts regularly occur, or Northwest regions, which are subjected to excess of water. So a special attention in model development was paid on account of the influence of water stress on plant production process.

Assessment of Natural Resource Potential of a Territory for Planning of Investment Development and Construction in Suburban Areas

“…Natural and resource potential of the landscape is a weighted value that characterizes the potentials of design areas located within it: (19) The twelfth block of methodology is intended to represent the results of natural and agricultural [31,32] potential assessment of the territory in the form of a series of electronic cards, comprising a set of factor maps and the final map describing the distribution of values of natural and agricultural potential within the study region. Agricultural potential calculation is tightly connected to the soil properties researches and experiments [20][21][22][26][27][28].…”

“…Landscape and soil maps for research region are developed by typical methods in scale of base material [16,[17][18][19].While the preparation of landscape maps objects of mapping are natural-territorial complexes in the rank of the individual tracts or typologically similar groups [20][21][22][23].Using and development of soil maps are impossible without pervasive soil researches, especially when the case is connected to the soil moisture [24][25][26][27][28].…”

Agro-ecosystem Model AGROTOOL Coupled with GIS for Simulation of the Spatial Variability of the Soil Hydrophysical Properties

“…In every of these horizons experimental studies following indicators of soil needed for the modeling with AGROTOOL were determined: soil hydrological constants (hygroscopic water content, wilting point, field capacity and porosity), bulk density, solid particles density and saturated hydraulic conductivity of soil. These data allow us to conduct a fully simulation the water retention curve [8,[16][17][18][19].…”

“…Development of approaches taking into account spatial variability of hydrophysical properties of soils during plants production process simulation (wheat crop) using the AGROTOOL model [16] in order to decision making support in practical adaptive landscape agriculture is the aim of this work.…”

Mathematical Modeling the Hydrological Properties of Soil for Practical Use in the Land Ecological Management

“…The direct measurements of the soil hydrological indicators are the rather labor-consuming procedures. Therefore, for the indirect quantitative estimation of these indicators and for prediction of the state of ecosystems it is widely applied mathematical modeling techniques [11][12][13][14][15][16][17][18].…”
