Such management not only encourages new tree growth but also augments the light levels reaching shaded crops, reduces weeds, and helps to maintain soil moisture.
Rainfall deviates relatively little each year from the annual averages and is effective enough to maintain soil moisture and surface drainage throughout the year.
Irrigation was applied for germination and seedling establishment and to maintain soil moisture.
For the RS experiments, the fields were irrigated to maintain soil moisture at field capacity or above for four weeks after transplanting.
Such systems are maintaining soil moisture between a desired range, optimal or adequate, for plant growth and/or quality (Muñoz-Carpena and Dukes 2005).
The use of the no-tillage system (NTS) and cover crops that maintain soil moisture would prove advantageous in the move toward sustainable agriculture.
Throughout the whole incubation period, the flask was periodically weighed and the required proportion of deionized water was added to maintain soil moisture content at 30%, or 60%, or 90% of WHC.
In addition, the major crop grown in many of these regions is rice and irrigation is applied to maintain soil moisture at near full saturation during the growing season, which often results in immediate increase in surface runoff during heavy rainfall over flooded rice paddies.
Over the course of the experiment 25 ml of HPLC-grade water was added to each pot to maintain soil moisture.
