Features of impulse sprinkling technology

Abstract

The principle of non-stop water supply to plants and soil in accordance with their water intake is progressive. Drip irrigation and impulse sprinkling correspond to this principle. Drip irrigation provides optimal water and nutrient regimes directly to the root system of plants. However, this irrigation is not effective enough under conditions of high temperature (over 25–35 °C) as growth processes are known to slow down and photosynthesis to cease, consequently affecting the yielding capacity. Impulse sprinkling provides optimal moisture level in the given layer, improved microclimate in the plant environment and water regime of plants within the whole vegetation period and is most effective within daytime. Through improvement of microclimate and plants' water regime within periods of high temperature and low air humidity under the conditions of South Kazakhstan, the technology of impulse sprinkling enabled increasing productivity of a clonal rootstock mother plantation for the 3 years of research on average by 19.4% compared to regular sprinkling. The applied technology provided optimization of layers' growth and development conditions upon decrease of the moistening of the soil layer of mother plantation bushes for derogation of their water regime after hilling the grown root layers.

Biochemical Fulvic Acid Modification for Phosphate Crystal Inhibition in Water and Fertilizer Integration

“…Water and fertilizer integration can realize the simultaneous supply of nutrients and water. Its main advantage is the establishment of optimal water and nutritive regime directly in the plant root system [ 12 , 13 ], which significantly increases the uptake of nutrients such as nitrogen and phosphate by plant roots and effectively improves the water and fertilizer utilization efficiency [ 14 , 15 ]. Drip irrigation technologies also bring new problems in nutrient loss and water waste.…”

Water Saving with Combined Irrigation Methods

“…These conditions can be created by fine-dispersed sprinkling. This type of sprinkling provides an optimal water regime in the soil, as well as improves the microclimate in the environment of plant development by reducing air temperature and increasing its humidity (Angold et al, 2016).…”

“…Frequent irrigation in small portions affects the microclimate of the surface air layer during irrigation, improves the water regime of plants, and increases the productivity of crops. In this, improvement of the microclimate mainly occurs during irrigation and within one or two days after watering (Angold et al, 2016).…”
