The rain water is very useful for growth of plants because it is mostly unpolluted and also leaching of salts takes place in the vecinity of plants.
The rainwater contains minerals from the clouds, walls of rainwater tanks etc, thy just do. But water from a tap (unless bore water) Has no minerals in them and is clean and has no minerals.
Its natural.
Rainwater is generally good for plants as long as it is free from pollutants and contaminants. It can be beneficial for plants for an extended period of time, as it provides natural nutrients and hydration.
A rainwater irrigation system collects and stores rainwater to be used for watering plants, reducing the need for tap water. This helps conserve water by utilizing a natural resource and reducing reliance on treated water sources.
They use rainwater which travels up the stem to the leaves to give them nutrients and help the plant grow.
Rainwater can be stored for up to one to two weeks before it may become less effective or harmful to plants due to the growth of algae or bacteria. It is best to use stored rainwater within this time frame to ensure the health of your plants.
It is just as good as any filtered water.
Rainwater harvesting is done by collecting and storing rainwater from rooftops or other surfaces in tanks or barrels. The collected rainwater can be used for various purposes like watering plants, flushing toilets, or even for drinking after proper filtration and treatment. Gutters and downspouts are typically used to direct the rainwater into the storage containers.
well the animals can get water from rainwater, pond, lakes etc etc#
A rain barrel filter can help improve the quality of collected rainwater by removing debris, sediment, and contaminants from the water as it enters the barrel. This helps prevent pollutants from entering the water supply and makes the water safer for various uses like watering plants or washing cars.
Toucans get their water from the plants they eat. It is also obtained through rainwater gathered in the leaves and plants, and occasionally from puddles on the ground.
Carbon dioxide (CO2) is the most common form of carbon that dissolves in rainwater. When CO2 from the atmosphere combines with rainwater, it forms carbonic acid (H2CO3), which is responsible for the mildly acidic nature of rain. This dissolved carbon in rainwater can then be utilized by plants for photosynthesis or can react with minerals in soil and water bodies.
