Economic, practical impacts of precision farming – with especial regard to harvesting
141-146Views:151Today agricultural practice is faced with a paradigm shift. In terms of natural resources, the World’s growing population calls for rational management and environment-conscious behaviour. Precision farming may provide a solution for the above mentioned criteria and problems. It has an array of technological equipment, elements and complete systems which are in themselves suitable to create conditions for efficient farming, to reduce environmental load and to provide farmers with optimal return on their investment. Agricultural production has started to focus mainly on efficient crop production and machine operation. Due to this trend, machinery exploitation emerges as a secondary priority for agricultural enterprises. The underlying reason behind this shift is primarily the rise of machinery operation costs. Efficient machinery operation can provide farmers with a solution to reduce their expenditure and through better logistical organization they can obtain extra returns. On the leading edge of my research is to introduce, quantitatively underpin and to justify the application of precision technologies. Our fundamental research methods rely on scenarios and economic calculations.

Effect of uncertainty on farmers decision making: Case of animal manure use
7-13Views:151Due to the high levels of manure application and the poor use efficiency of manure, the European agriculture is held responsible for a considerable negative impact on surface water quality (Langeveld et al., 2007). This problem has emerged particularly in Western-European countries such as the UK, Belgium, The Netherlands and Denmark, facing a large expansion and intensification process in the livestock production since the 1960s (Van der Straeten et al., 2008). Policy measures related to the application of manure on the land encompass two major measures: emission rights, understood as the amount of nutrients which can be applied on the land, differentiated by crop and the N spreading calendars, whereby the manure can only be applied when the crop needs nutrients. The fundamental aim of this pillar is to maximising application rate while avoiding overfertilisation. Maximizing the application rate is related to the economic sustainability of the agricultural sector, by altering the manure surplus, while avoiding overfertilisation is imperative in enhancing ecological sustainability, by preventing nitrate leaching to surface and soil waters. For nitrate policy to meet its target, the farmers should not exceed their emission rights, however make optimal use of their emission right for manure. Consequently, the successful implementation of sink-related measures will strongly depend of the absorptive capacity of farmers towards new ways of nutrient management in general and of animal manures in particular.

Changes in costs of precision nutrition depending on crop rotation
59-63Views:129By applying precision nutrition the yield heterogeneity owing to the different features of soil spots can be taken into consideration. The planned and sprayed fertilizer adjusted to the expected yield rendered to soil spots can reduce the negative effects of artificial chemicals on soil and environment. The aim of this paper is to examine how the quantity and the cost of fertilizer (material and operational) will change on spot level on a certain plot during a five-year period, considering crop rotation, too. The following crops are in the rotation: winter wheat, corn and sunflower. Precision nutrition can be used in all the cultures mentioned above. Our earlier (static) model calculations have revealed that the threshold price of precision production was lower by 31% than in conventional technology. So it is necessary to explore for a longer period how the profitability of precision nutrition reacts to the changes in input and yield prices in different crops. The risk receptivity of precision nutrition can be characterized with the help of price sensitive analyses. Effects on profitability of other technological elements are not analysed in this paper.

A disaggregated analysis of monetary policy effects on the agricultural sector in Nigeria
47-58Views:399This study provides a disaggregated analysis of the effects of monetary policy shocks on the agricultural sector in Nigeria from 1981Q1 to 2016Q4. The study utilized the generalized impulse responses and the normalized generalized forecast error variance decompositions from an underlying VAR model, which are order-invariant. The four monetary policy variables used in the study are interbank call rate, monetary policy rate, broad money supply and exchange rate; while the four agricultural sub-sectors investigated are crop production, forestry, fishing and livestock. The study also controlled for the general price level and other economic activities in the overall economy. The findings indicate that the aggregate agricultural sector and its various sub-sectors consistently responded negatively to unanticipated monetary tightening in most of the forecast horizon; while the immediate impact of monetary policy shocks is transmitted to the agricultural sector through the interest rate and money demand (credit) channels. The findings further indicate that apart from these two channels, the roles of monetary policy rate and exchange rate are non-negligible in the long-run. The role of money supply channel in spreading monetary policy shocks to the agricultural sector remained muted all through. The study concludes that the monetary authority should evolve interest rate, credit, and exchange rate policies that will promote the development of the agricultural sector in Nigeria.

Mitigation activities to reduce emission of agricultural greenhouse gases in Hungary
115-119Views:139Pressure on natural resources and the global environment have been identified as the most important challenges to maintain prosperity and improve environmental care. Agriculture is responsible for only a small proportion of carbon dioxide (CO2) emissions, but the sector is more closely associated with emissions of other greenhouse gases such as methane (CH4) and nitrous oxide (N2O). The global warming potential of agricultural activities defined as greenhouse gas (GHG) emissions in CO2 equivalents is relatively low in Hungary, when calculated per land area. However this difference decline, when a GHG emission is calculated per product unit, as yields are lower then in West European countries. Environmental load caused by agriculture is also low in Hungary, where increasing part of EU resources are used for the long-term preservation of natural resources and for the raising of awareness of sustainable farming. The strength of the environmental situation of Hungary, consist of several elements, such as the rich bio-diversity, the significant size of territories falling under natural protection, the extent and importance of forests and the low environmental load from crop production. Among the weaknesses the nitrate load of the animal husbandry farms, the increasing water and wind erosion, the soil compaction and degradation have to be taken into consideration. Climate change has high risk potential and the mitigation activities of the New Hungary Rural Development Programme (HRDP) are investigated in this paper with the aim to increase mitigation activities in rural area and reduce the causes of climate change.

How to improve the performance of agriculture in Mongolia by ICT
59-64Views:321Agriculture is one of the most important sectors for the Mongolian economy. Also, self-sufficient food is a significant target that has a vital role in the food safety of people in Mongolia. But due to climate change, not proper management, and lack of technology, the Mongolian agricultural sector is facing several issues. So this article aims to find some potential solutions to improve this situation, especially for the crop production sector in Mongolia. To define the current situation of Mongolian agriculture, we used statistical data and reports and recent scientific articles as well as online sources. The current situation of Mongolian agriculture is defined using SWOT analysis reported by the Ministry of Food, Agriculture, and Light Industry of Mongolia. Based on this research, we discuss the possibility of using a drone to improve the performance of agriculture in Mongolia. As a result, a drone is effective in enhancing the performance of agriculture performed by householders. Also, two effective models that are based on ICTs to address soil erosion and harvest losses issues in Mongolia are defined in this article.
