Annual water use varied strongly with variety and training system. For non-fruiting trees however, annual water use per unit leaf area at the end of the season showed a consistent relationship for trees of all variety x training system combinations. In the final year, the presence of fruit ...
Table 2 shows the irrigation levels with supply water and the dilutions (supply water + aquaculture wastewater) applied during the experimental period. To verify the uniformity of water distribution in the drip irrigation system installed in the experimental unit, the water distribution ...
Depth:The depth of the soil depends on the container or planting area. In containers, provide enough soil depth to accommodate the cactus’s root system. For garden planting, ensure that the soil is well-draining to a depth of at least 12-18 inches (30-45 cm) or more. ...

and the jet system sucks and discharges the chopped soil to form the trenches required for pipeline burying. It is mainly composed of the main bracket, reamer system, jetting system, mud drainage system, Crawler, power system, monitoring system, etc. The mechanical trencher combines mechanical cut...
The objectives of this research were to explore the characteristics of water balance, energy transfer and carbon exchange of irrigated pear orchards by a combination of multiple measurement methods (eddy covariance system, sap flow method, and the other equipment). Experiments from 08/01/2011 to ...

WaterIrrigationDrainagePartial rootzone drying (PRD) means that part of the root system is watered as in full irrigation while the rest is exposed to soil drying. This practice is predicted to influence field hydrological circle. We studied the effect of this practice on soil water distribution,...
Results indicate that localized addition of N through the irrigation system at rates used in this experiment increased the N losses through leaching by 3.8 kg N/ha, accounting for about 8% of fertilizer N. Negligible amounts of nitrate-N were lost from grassed alleys, suggesting a beneficial ...
Selenite can penetrate root cells through passive diffusion [69], accounting for the occurrence of Se accumulation in roots in soil with high selenite stress. Other studies [68,70] have found that selenite uptake by the plant root system is an active process, which may be partially mediated ...
