From the time the bamboo is first planted, until the end of it’s first summer of growth, it will need to maintain a regular supply of water, but should ensure that there is good grainage so as to avoid waterlogging which is common in heavy, clayey or highly compacted soil. Bamboo maintains more consistent high yields under irrigated conditions as the growth is more predictable and the plants are continuously served with the right amount of water and fertilizer.
Drip irrigation, is an irrigation method that saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. It is done through narrow tubes that deliver water directly to the base of the plant
The advantages of drip irrigation are:
- Fertilizer and nutrient loss is minimized due to localized application and reduced leaching.
- Water application efficiency is high.
- Field leveling is not necessary.
- Fields with irregular shapes are easily accommodated.
- Moisture within the root zone can be maintained at field capacity.
- Soil type plays less important role in frequency of irrigation.
- Soil erosion is minimized.
- Weed growth is minimized.
- Water distribution is highly uniform, controlled by output of each nozzle.
- Labour cost is less than other irrigation methods.
- Variation in supply can be regulated by regulating the valves and drippers.
- Fertigation can easily be included with minimal waste of fertilizers.
- Foliage remains dry, reducing the risk of disease.
