Discovering Spatio-Temporal Patterns in Precision Agriculture Based on Triclustering

Abstract

Agriculture has undergone some very important changes over the last few decades. The emergence and evolution of precision agriculture has allowed to move from the uniform site management to the site-specific management, with both economic and environmental advantages. However, to be implemented effectively, site-specific management requires within-field spatial variability to be well-known and characterized. In this paper, an algorithm that delineates within-field management zones in a maize plantation is introduced. The algorithm, based on triclustering, mines clusters from temporal remote sensing data. Data from maize crops in Alentejo, Portugal, have been used to assess the suitability of applying triclustering to discover patterns over time, that may eventually help farmers to improve their harvests.

Improving the methods of determining the amount of non-agricultural land use in agriculturae in Uzbekistan

“…We propose to calculate this using the following formula. UOPaf = UOPlh* APha * Ym (1) Where: UOP af -the amount of the fine for use of the land plot for other purposes, in UZS; UOP lh -land used for other purposes, per hectare; APh a -Amount of profit at current prices per 1 hectare, in UZS (calculated according to formula (2); Y m -years of agricultural land used for other purposes. AP ha in Formula 1 is the average annual income received from the use of land for its own purposes, which is calculated by the following formula; Where: Np -normative yield of agricultural crops, ts/ha; B b -bonitet ball; A ap -the average annual price of the relevant type of agricultural products sold in farmers markets, thousand UZS/ts.…”

“…Today, global climate changes taking place in the 21st century, which are considered the main means of meeting the demand of the population of agricultural lands for food and raw materials, the aggravation of the ecological crisis as a result of the decrease in Biological Diversity, the further urgency of the issue of ensuring food security of the country in the conditions of And the preservation of the current attitude to the land was considered by the mutukhassis as a consequence of the fact that "by the 2050 year the total area of crops per capita and fertile land accounted for only a quarter of the level of the 1960 year" [1][2][3][4][5]. One of the main measures aimed at protecting and increasing agricultural land productivity is to improve the mechanisms of economic incentives for its users.…”

Innovative organization and increase of efficiency of agricultural melioration measures of Uzbekistan

“…Their level of availability and quality plays an important role not only in the use of arable land but also in increasing the effectiveness of melioration measures. In particular, the fact that the country is located in an arid (irrigated) region and agricultural production is mainly based on irrigated agriculture, further enhances the priority of this factor [20]. Due to the fact that the main object of melioration works is the mechanical composition and properties of the fertile soil,…”
