In Korea, irrigation technology using subsurface drip (SDI) is new in agriculture system. Many limitations of SDI are not well known. can damage crops from overwatering. To address this weakness, it important to improve and test the applicability with air injection (oxygation). Therefore we investigated soil oxygen (O2) carbon dioxide (CO2), root characteristics yield maize two conditions moist...

The hypothesis of this paper is that infiltration into drip irrigated soils can be described by simple spherical considerations as well two dimensional (2D) numerical modeling. major goal was to test a very model based on geometry sphere formulas, and compare it with elaborated solutions field experiments. Detailed analysis soil–water under trickle regimes shown pre-requisite in the search for ...

Evaporation from the soil surface (E) can be a significant source of water loss in arid areas. In sparsely vegetated systems, E is expected to be a function of soil, climate, irrigation regime, precipitation patterns, and plant canopy development and will therefore change dynamically at both daily and seasonal time scales. The objectives of this research were to quantify E in an isolated, drip-...

The Cal Poly ITRC irrigation evaluation programs have been widely used to assess the global distribution uniformity (DU) of drip and microsprayer irrigation systems. The field procedures and formulas used in the program are presented in this paper. The system DU is estimated by mathematically combining the component DU values. DU components include pressure differences, "other causes" (such as ...

Background: Water in any form is the prime constitute of plant growth and development. Right amount water applied at right time quantity to crop will helpful get maximum yield potential that crop. This possible with surface drip irrigation method. Uniform application through emitters necessary aspect avail benefits like higher use efficiency irrigation. Uniformity system can be measured by vari...

Plots naturally infested with Rotylenchulus reniformis were sampled in the spring of 2006 and 2007 at depths of 15 and 30 cm in the bed, furrow over the drip tape, and "dry" furrow, and at approximately 40 to 45 cm depth in the bed and dry furrow. Then, 1,3-dichloropropene (Telone EC) was injected into the subsurface drip irrigation at 46 kg a.i./ha, and 3 to 4 weeks later the plots were resamp...

Providing the population with clean drinking water and agricultural water, which provides humanity food, has become one of main problems around world. In Republic Uzbekistan, as well in other countries world, shortage is growing every year. The article states that factors for mitigating shortages agriculture introduction water-saving technologies. Among technologies, most effective system drip ...

Nowadays, smart irrigation is becoming an essential goal in agriculture, where water and energy are increasingly limited resources. Its importance will grow the coming years agricultural sector optimal use of resources environmental sustainability more important every day. However, implementing not easy task for most farmers since it based on knowledge different processes factors that determine...
