“…Numerous foreign and domestic studies of the cultivation of both dry and aerobic rice show [1][2][3][4][5][6][7][8] that the issue of transition from flooded rice to aerobic rice is relevant and should be worked out in accordance with all modern ecological and reclamation requirements that are currently imposed on production agricultural products, including rice culture [9,12]. High interest among rice producers, as a rule, is associated with the further impossibility and/or inefficiency of rice production using the traditional technology of rice cultivation with continuous or shortened flooding of rice paddies due to the lack or insufficiency of the required volume and / or quality of irrigation water, lack of the necessary technical support for the implementation of all agrotechnical methods necessary for the normal cultivation of rice, reducing the soil reclamation state to a level at which the introduction of organic and mineral fertilizers does not compensate for the low soil fertility and is ineffective and economically inexpedient [13][14][15][16].…”

Currently used in Russia traditional technologies of rice cultivation with continuous or short-term flooding of rice paddies are ineffective for a number of factors, the main of which are the high cost and high labor intensity of rice production. Research in the field of rice cultivation has identified four main promising technologies that can reduce the cost of rice produced: 1 - intermittent flooding; 2 - periodic moistening without creating a layer of water; 3 - sprinkling, including surface irrigation; 4 - drip irrigation. The purpose of our research was to develop a new drip irrigation rice cultivation technology adapted for the climatic and soil conditions of the Krasnodar Territory. As a result of the research carried out, a drip irrigation technological scheme was developed and implemented for LLC “Chernoerkovskoye” of the Slavyansky district of the Krasnodar region. The developed scheme of rice cultivation on drip irrigation has proven its effectiveness, expressed in improving the reclamation state of soils, increasing the profitability of production and increasing the yield, reducing the irrigation rate, the cost of rice grain and labor intensity.

“…It is known from the world practice of rice production [1][2][3][4][5][6] that rice is a moisture-loving crop that requires large volumes of irrigation water and labor costs for its production. Therefore, scientific research to find new solutions to reduce the cost of rice production has always been relevant, including in the historical aspect of rice cultivation [7][8][9].…”

The domestic and foreign research in the field of rice cultivation carried out over the past 10-15 years has identified four main promising technologies that can reduce the cost of rice produced: 1 - intermittent flooding; 2 - periodic moistening without creating a layer of water; 3 - sprinkling, including surface irrigation; 4 - drip irrigation. Drip irrigation of rice is the most priority area of research, since it can significantly reduce the irrigation rate, labor costs, the cost of rice production and anthropogenic load. The purpose of our research was to develop a new technology of rice cultivation with drip irrigation adapted for the climatic and soil conditions of the Krasnodar Territory. As a result of the research carried out, a drip irrigation technological scheme was developed and implemented for LLC “Chernoerkovskoye” of the Slavyansky District of the Krasnodar Territory. The developed scheme of rice cultivation on drip irrigation has proven its effectiveness, which was expressed in improving the reclamation state of soils, increasing the profitability of production by 22% and increasing the yield by 20%, reducing the irrigation rate by an average of 5.3 times, the cost of rice grain by 15% and labor intensity by 34%.

“…These naturally waterlogged areas can be found globally in wetlands, river basins, or lakesides, for example [65]. Waterlogging may also be caused by human interventions such as irrigation, wrongly designed drainage methods, and other surface alterations (e.g., ridges) [65,66]. Due to continuous irrigation, waterlogging is prevalent in agricultural areas in mostly arid and semi-arid areas where irrigation is needed to sustain agricultural production.…”

“…For example, the crop models SWAGMAN, DRAINMOD, and APSIM take the effect of water excess stress on crop yield into consideration in agricultural management [3]. Recently, efforts were made to model waterlogging in irrigated paddy rice to understand human interventions in the irrigation schemes and the resulting yield reduction of waterlogged area [66]. To simulate waterlogging in irrigated agriculture, natural processes need to be considered, but also the hydraulic structures created by humans and the interventions taken place within the system are of importance (e.g., irrigation, gates) [66].…”

Waterlogging is an increasingly important issue in irrigated agriculture that has a detrimental impact on crop productivity. The above-ground effect of waterlogging on crops is hard to distinguish from water deficit stress with remote sensing, as responses such as stomatal closure and leaf wilting occur in both situations. Currently, waterlogging as a source of crop stress is not considered in remote sensing-based evaporation algorithms and this may therefore lead to erroneous interpretation for irrigation scheduling. Monitoring waterlogging can improve evaporation models to assist irrigation management. In addition, frequent spatial information on waterlogging will provide agriculturalists information on land trafficability, assist drainage design, and crop choice. This article provides a scientific perspective on the topic of waterlogging by consulting literature in the disciplines of agronomy, hydrology, and remote sensing. We find the solution to monitor waterlogging lies in a multi-sensor approach. Future scientific routes should focus on monitoring waterlogging by combining remote sensing and ancillary data. Here, drainage parameters deduced from high spatial resolution Digital Elevation Models (DEMs) can play a crucial role. The proposed approaches may provide a solution to monitor and prevent waterlogging in irrigated agriculture.
