n the twenty years that preceded 1920 I there was a 245 percent increase in the average per-acre price of farmland (including improvements) before land values fell sharply. Today’s escalation in land values-364 percent between 1957 and 1977-prompts some pointed questions: Have land prices reached their peak? If not, when will they plateau, if ever? Will they then decline and, if so, will the de...
Decisive factor of scale of land is the capacity of management and control of agricultural operation subject, which is strengthened with improvement of skills. Only if scale of land is enlarged accordingly, then economic profit can be gained. Under such external circumstances as reduction of agricultural comparative advantage and fluctuation of relative factor prices brought about by economic d...
The problem of evaluation of agricultural land suitability is consid ered as a fuzzy modeling task. For assessment of land suitability, it is proposed to use fuzzy indicators. Application of individual fuzzy indicators gives oppor tunity for assessment of suitability of lands as degree or grade of performance when the lands are used for agricultural purposes. Using composite fuzzy indi cator...
An artificial neural network is a system based on the operation of biological neural networks, in other words, is an emulation of biological neural system. Artificial Neural Networks or simply Neural Networks are powerful general purpose computing tools. They have become popular in the analysis of remotely sensed data, particularly in classification or feature extraction from image data more ac...
Agricultural land management, such as fertilization, liming, and tillage affects soil properties, including pH, organic matter content, nitrification rates, and the microbial community. Three different study sites were used to identify microorganisms that correlate with agricultural land use and to determine which factors regulate the relative abundance of the microbial signatures of the agricu...
Future land cover will have a significant impact on climate and is strongly influenced by the extent of agricultural land use. Differing assumptions of crop yield increase and carbon pricing mitigation strategies affect projected expansion of agricultural land in future scenarios. In the representative concentration pathway 4.5 (RCP4.5) from phase 5 of the Coupled Model Intercomparison Project ...
The term, biosolids, is generally used to refer to those waste products that have been stabilized by treatment of the sewage sludge for beneficial reuse through appropriate management (Davis, 2002). The agronomic and environmental benefits from the organic material and fertilizing elements contained in the biosolids are essential for maintaining soil fertility. This has been a major reason for ...
Increase in CO2 emissions induced by agricultural inputs in China since its socialist market economic reforms may hinder its sustainable economic development. More attention has been paid to changes in agricultural land use and overall land use benefit; however, relatively less attention has been paid to changes in CO2 emissions induced by agricultural inputs in China since the reforms. The car...
