Offer Description
Research of the synergy of remote sensing methods and hydropedological soils properties for irrigation management
Supervisor: prof. Ing. Viliam Bárek, CSc.
Workplace: Institute of Landscape Engineering
Field of study: Agriculture and Landscaping
Study program: Landscape Engineering
Form of study: full-time
Theses:
The water regime of plants represents the management of plants with water from its intake, transport, consumption to its release. It is given by the genetic constitution of the species allowing to face the current action of environmental factors (or to use them) with targeted phenotypic adaptations. The basic condition for achieving maximum yields of agricultural crops is that the crop formation of the given plant takes place at a certain degree of balance between temperatures and precipitation, while this degree of balance is quite specific for the given crop and its stage of development. The essence of the solution lies in the optimization of the irrigation delivery date. Multispectral images allow us to monitor the state of the vegetation and the amount of vegetation on the soil surface. They use the visible and near-infrared part of the electromagnetic spectrum. This type of images is used to obtain information about the condition of the vegetation and plant growth, as it allows obtaining information about possible nutrient deficiencies, damage by pests or other manifestations of abiotic stress on plants. The use of multispectral images in agriculture is mainly aimed at improving water management and determining the water stress of plants. In synergy with the monitoring of soil moisture and by monitoring changes in soil water potential, the results of the work can provide a basis for practical management of irrigation operations with the lowest possible economic and technological inputs. The results would thus find the widest possible scientific and practical application.
Reasoning:
The presented topic deals with the issue of managing the moisture regime of the soil profile. Based on the measurement of the entire complex of hydrophysical properties of soils and multispectral imaging, the goal is to determine the basic parameter of plants' manifestations of water stress, which should determine as accurately as possible the need to increase moisture in the soil profile in real time. This is an innovative approach, since the irrigation management methods used so far are based only on the time principle, or on the basis of soil moisture measurement, which may not correspond to the needs of the plants at all. The addressed topic will fulfil the use of the technical potential of the equipment procured within the operational program Integrated infrastructure for the project: Sustainable systems of intelligent farming taking into account the challenges of the future 313011W112, co-financed from the resources of the European Regional Development Fund (SmartFarm).
Financial coverage:
Instrumentation for field and laboratory experiments was purchased from the Operational Program Sustainable Smart Farming Systems Considering Future Challenges 313011W112, co-financed by the European Regional Development Fund (SmartFarm). The dissertation will be supported within the VEGA projects no. 1/0373/21, Effective irrigation management as a tool for adaptation to a changing climate and project APVV-20-0071, Precise irrigation management as an adaptation measure to climate change, which are being addressed at the Institute of Landscape Engineering.
Výskum synergie metód DPZ a hydropedologických vlastností pôdy pre riadenie závlahy
Školiteľ: prof. Ing. Viliam Bárek, CSc.
Pracovisko: Ústav krajinného inžinierstva
Študijný odbor: Poľnohospodárstvo a krajinárstvo
Študijný program: Krajinné inžinierstvo
Forma štúdia: denná
Tézy:
Vodný režim rastlín predstavuje hospodárenie rastlín s vodou od jej príjmu, transportu, spotreby až po výdaj. Je daný genetickou konštitúciou druhu umožňujúcou čeliť aktuálnemu pôsobeniu faktorov prostredia (alebo ich využiť) cielenými fenotypickými adaptáciami. Základnou podmienkou dosahovania maximálnych úrod poľnohospodárskych plodín je, aby tvorba úrod danej rastliny prebiehala pri určitom stupni rovnováhy medzi teplotami a zrážkami, pričom tento stupeň rovnováhy je pre danú plodinu a stupeň jej vývoja celkom špecifický. Podstata riešenia tkvie v optimalizácii termínu dodania závlahy. Multispektrálne snímky nám umožňujú sledovať stav porastu a množstvo vegetácie na povrchu pôdy. Využívajú viditeľnú a blízku infračervenú časť elektromagnetického spektra. Tento druh snímok sa využíva na získavanie informácií o stave porastu a raste rastlín, nakoľko umožňujú získať informácie o prípadnom nedostatku živín, poškodení škodcami či iných prejavoch abiotického stresu na rastliny. Využitie multispektrálnych snímok v poľnohospodárstve je zamerané najmä na zlepšenie hospodárenia s vodou a určovanie vodného stresu rastlín. V synergii s monitoringom pôdnej vlhkosti aj cestou sledovania zmien potenciálu pôdnej vody môžu výsledky práce poskytnúť základ pre praktické riadenie prevádzky závlah s čo možno najnižšími ekonomickými a technologickými vstupmi. Výsledky by tak našli čo najširšie vedecké a praktické uplatnenie.
Zdôvodnenie:
Predkladaná téma sa zaoberá problematikou riadenia vlhkostného režimu pôdneho profilu. Na základe merania celého komplexu hydrofyzikálnych vlastností pôd, a multispektrálneho snímkovania si práca kladie za cieľ stanoviť základný parameter prejavov rastlín na vodný stres, ktorý by mal čo najpresnejšie určiť potrebu zvýšenia vlhkosti v pôdnom profile v reálnom čase. Toto je inovatívny prístup, keďže doteraz používané metódy riadenia závlah sú založené len na časovom princípe, prípadne na základe merania vlhkosti pôdy, čo vôbec nemusí korešpondovať s potrebami rastlín. Riešená téma naplní využívanie technického potenciálu prístrojového vybavenia obstaraného v rámci operačného programu Integrovaná infraštruktúra pre projekt: Udržateľné systémy inteligentného farmárstva zohľadňujúce výzvy budúcnosti 313011W112, spolufinancovaný zo zdrojov Európskeho fondu regionálneho rozvoja (SmartFarm).
Finančné krytie:
Prístrojové vybavenie pre poľné a laboratórne experimenty bolo zakúpené z operačného programu Udržateľné systémy inteligentného farmárstva zohľadňujúce výzvy budúcnosti 313011W112, spolufinancovaný zo zdrojov Európskeho fondu regionálneho rozvoja (SmartFarm). Dizertačná práca bude podporená v rámci riešených projektov VEGA č. 1/0373/21, Efektívne riadenie závlah, ako nástroj adaptácie na meniacu sa klímu a projektu APVV-20-0071, Presné riadenie závlah ako adaptačné opatrenie na klimatickú zmenu, ktoré sú na Ústave krajinného inžinierstva riešené.
