Dynamics of Total Water Consumption and Productivity of Periodically Humidified Rice at Overhead Irrigation and Drop Watering in the Volgograd Region

Development of technical solutions for environmentally safe irrigation

“…Irrigation affects the structural composition of soil, the size of agronomically valuable aggregates, porosity, hardness, as well as may be accompanied by accumulation of salts, leading to the death of plants. Scientists have developed and continue to study ways to eliminate the negative effects of sprinkling irrigation due to the mechanical impact of droplets on the soil leading to its compaction and formation of soil crust depending on the type of soil (Table 1) [9][10][11]. It is known that under the same conditions the amount of erosion depends on the duration of rain hitting the soil, and on the indicators that characterize the energy characteristic of rain, namely the average drop diameter, intensity, drop fall velocity, specific power, and rain pressure force.…”

Effect of the structure of artificial rain on the soil

“…With an increase in soil moisture, water permeability decreases, and surface runoff increases, contributing to the washout of the fertile layer. Given the insufficient experimental development of water absorption into the soil and methods of its intensification during irrigation with frontal sprinklers [11][12][13][14][15][16], it is necessary to conduct experimental studies to develop measures to prevent irrigation soil erosion [17,18,19,20].…”

Modernization of structural elements of a hydrocyclone to improve the efficiency of irrigation water treatment

“…There are many methods of water treatment and wastewater treatment [10,11,12], these include sorption filters with different loads [13,14,15,16,17], the use of reagents, but mechanical cleaning filters carry a heavy load. The correct selection of equipment assumes effective water purification and high-quality irrigation of crops [18][19][20][21][22][23]…”
