A water tube/pipe made of PVC is usually used to practice AWD method. The main purpose of the tube is to monitor the water depth. The tube allows measuring water availability in the field below the soil surface. The usual practice is to use a pipe of 7–10 cm diameter and 30 cm long, with perforations in bottom 20 cm.
Rice polyculture is the cultivation of rice and another crop simultaneously on the same land. The practice exploits the mutual benefit between rice and organisms such as fish and ducks: the rice supports pests which serve as food for the fish and ducks, while the animals' excrement serves as fertilizer for the rice.
The traditional compost heater exploits the heat of a large compost heap to warm a house. This type requires a big heap, intertwined with a spiral water hose. The circulating water conducts heat to the building, where it can be fed to a heating circuit. The heap must contain at least 8,000 liters of biomass to maintain a temperature during the ...
Using less water and using a drone to fertilize are new techniques that Van is trying and Vietnam hopes will help solve a paradox at the heart of growing rice: The finicky crop isn’t just ...
Sub-irrigated planter (SIP) is a generic name for a special type of planting box used in container gardening and commercial landscaping. A SIP is any method of watering plants where the water is introduced from the bottom, allowing the water to soak upwards to the plant through capillary action . [ 1 ]
In its simplest form, nutrient-enriched water is pumped into containers with plants in a growing medium such as Expanded clay aggregate At regular intervals, a simple timer causes a pump to fill the containers with nutrient solution, after which the solution drains back down into the reservoir. This keeps the medium regularly flushed with ...
Reduced water consumption: This is because rice plants do not require continuously flooded conditions to grow, [13] and that water savings can be achieved without compromising yields. Studies have shown that SRI can reduce water use by 25-50% compared to conventional rice farming, while maintaining or increasing yields. [14] [15]
Today, of the 236,112 acres of rice fields that were documented, about 39,000 acres of tidal rice fields still have dike and water infrastructure and are managed for wildlife, such as Nemours.
