Greenhouse Irrigation: Opportunity for Reuse

Greenhouse irrigation systems can reuse water. Check out the environmental benefits of reusing irrigation water in greenhouses.

Water is becoming an increasingly important resource as the world moves into the future. The world constantly needs more water yet deals with a limited quantity. In fact, it is estimated that half the world’s population could be impacted by water scarcity by 2025

Greenhouse irrigation systems are one way through which this problem can be addressed. By reusing water within a greenhouse, you can help the surrounding community, the environment, and yourself. Today, we’ll find out how!

Water Conservation

One of the largest and most direct ways in which reusing irrigation water helps the environment is by conserving water. It is a simple but profound concept: by reusing water, less water is necessary. 

Since water is limited but is essential to life, using less of it helps everything and everyone in the surrounding area. This ranges from the local wildlife to the neighbors down the street. 

It helps wildlife by reducing the amount of water localities draw from nature. This can lead to preventing streams from being diverted or lakes from being drained. 

It also helps the surrounding community. By drawing less on the area’s supply of water, there is more available for everyone else. While this may not seem like a big positive everywhere, it is critical in places facing water insecurity. 

In these areas, community efforts or local legislation often restrict the amount of water that can be used. By reducing your greenhouse’s consumption, you can avoid the impact of these efforts while also helping everyone else. 

Conserving water through greenhouse irrigation water reuse is becoming easier than ever. You can buy supplies from that are tailored towards environmentally-friendly greenhouse setups.

Less Pollution

Another positive for the environment comes from less pollution. Agriculture often requires fertilizers and pesticides. Then, these chemicals enter the water table through the runoff from plants. 

This creates problems for plant and animal life. Fertilizers can upset the balance of delicate ecosystems, creating algal blooms in bodies of water. Pesticides can heavily impact the quality of animal life, killing or poisoning different species. 

Reusing water reduces the amount of polluted water that enters the environment. Simply preventing these contaminants from ever having the chance to run wild helps a lot. 

Oftentimes, reusing water also leads to better control of the contaminants in water. When the reused water receives treatment, its chemical composition becomes known. This makes it easier to reuse the excess fertilizer in the water, instead of putting it into the environment. 

Even the sediments in the water are an environmental problem. Sediment pollution disrupts the ecosystem and can even impact the flow of streams and rivers. Preventing them from ever entering the water can prevent this. 

Wastewater treatment Opportunity

Most smaller-scale greenhouses that wish to reuse water will focus on reusing their own irrigation water. However, new methods are being developed where larger-scale greenhouses can treat and reuse wastewater.

Water receives treatment using a biological activated carbon filter which results in high-quality irrigation water. This prevents any dangerous substances from entering the water and, thus, entering the plants. 

However, the water still retains necessary nutrients such as nitrogen and phosphorus. With these already present, it may result in the greenhouse owner having to add less fertilizer. This gives an added benefit to an already beneficial system. 

By reusing and treating wastewater to be used in greenhouse irrigation systems, producers can have access to high-quality irrigation water while assisting with another necessary environmental process.

Increased Crop Production

In general, if you want to produce more of a crop, you’ll need more space to grow it. If these crops are grown in greenhouses, that means you’ll need to construct more greenhouses. 

Additional construction is always a field that impacts the environment. It uses energy, disrupts the local ecology, and becomes another drain on resources. 

However, if you can increase the crop yield from an already present crop, you don’t need to build more greenhouses to get the same yield. Reusing greenhouse irrigation water can help increase crop yields, which can be particularly helpful if you have limited access to space and land.

It can also help to continue to reduce your reliance on additional water. Another greenhouse would require another full irrigation system. This intensifies all the problems related to using excess water. 

Reusing water is also a budget-friendly way of irrigating your crop, even for high-value products. This can help increase your own profit.

On the whole, increased crop production can increase food security which has other environmental impacts.

How Reusing Water Helps You

When you reuse irrigation water, you don’t just help the environment, you help yourself as well. Many of the benefits related to water reuse involve saving money. 

Most know that using less water will save more money. Setting up a proper system for reusing water might take an initial investment but will allow for less water usage. This can pay off over time.

However, the importance of this saving grows as time progresses. In general, the cost of water goes up every year. So, reducing the amount of water you use now can prevent the cost from ballooning in the future. It has immediate and future benefits. 

Meanwhile, the growing impact of climate change is leading to more droughts across the world. By using less water, you can ensure your greenhouse can make it through periods of water scarcity. 

Creating Effective Greenhouse Irrigation

Reducing and reusing greenhouse irrigation water can have a big impact. It creates an efficient and cost-effective greenhouse system. It also helps the environment and prepares both individuals and communities for the future.
