Low-pressure superficial irrigation technology is a revolutionary approach to water and nutrient delivery, designed with precision and efficiency in mind. This innovative system, protected by national patent rights, utilizes a needle irrigation method that ensures optimal performance in various agricultural settings.
One of the key advantages of this system is its excellent anti-clogging capability. The infiltrator and water chute are sealed within the infiltration needle, making it highly resistant to sediment blockage from external sources. Unlike traditional drip irrigation systems, which are prone to clogging due to evaporation and mineral buildup, this low-pressure system allows for direct watering at a depth of 2 cm, minimizing the risk of scale formation and ensuring consistent flow. In case of accidental clogging, the needle can be quickly removed, and the water tank cleaned in just a few seconds—no need for extensive water filtration, making it ideal for use in areas with high mineral content or poor water quality.
Another significant benefit is its exceptional water-saving potential. Compared to sprinkler and drip irrigation methods, which typically save around 50% and 40% of water respectively, this system offers even greater efficiency. By delivering water directly to the root zone, it minimizes surface evaporation and reduces the amount of water lost to capillary action. On average, each acre requires only 2-4 cubic meters of water per irrigation, compared to over 60 cubic meters for flood irrigation. This not only conserves water but also supports sustainable farming practices.
In greenhouse environments, this technology helps reduce disease occurrence and improves crop quality. High humidity and moisture levels are major contributors to fungal and bacterial diseases such as gray mold, powdery mildew, and root rot. By keeping the soil surface dry and reducing humidity, the system creates an unfavorable environment for pathogens, significantly lowering the need for chemical pesticides. This results in healthier crops, fewer pesticide residues, and higher-quality produce.
Additionally, low-pressure superficial irrigation enhances greenhouse temperature by reducing moisture evaporation and condensation on the film. This leads to an increase in temperature by 2–3°C, promoting earlier growth and increasing yield by up to 30%. It also allows for precise control of humidity, which is crucial for different crop types.
This system also saves fertilizer by delivering nutrients directly to the roots through dissolved water, improving absorption rates by more than 50%. It prevents soil compaction by reducing excessive fertilizer application, preserving the structure of the soil and reducing the growth environment for harmful pathogens like root nematodes.
Energy consumption is another advantage. With a working pressure as low as 2–10 meters of water column, the system uses less power than traditional drip irrigation, making it more cost-effective and environmentally friendly.
Labor costs are significantly reduced as well. Once installed, the system operates automatically, requiring minimal human intervention. It also suppresses weed growth by delivering water only to the crop roots, reducing the need for manual weeding or herbicides.
The system is also efficient in terms of fertilizer use. Only a fraction of the traditional amount is needed, preventing over-fertilization and crop burn. Overwatering is discouraged, as it can lead to pathogen spread and reduced plant health. Precise watering ensures that each plant receives the right amount of moisture without excess.
By focusing irrigation on the root zone, the system promotes stronger, healthier root development while avoiding the negative effects of overwatering, such as oxygen deprivation and anaerobic respiration.
Finally, the system increases land use efficiency by eliminating the need for fallow periods and reducing soil-borne diseases. It also allows for better land management, as no tilling or trenching is required, leading to a 5–7% increase in usable land area.
Overall, low-pressure superficial irrigation is a game-changer in modern agriculture, offering a sustainable, efficient, and effective solution for farmers looking to optimize resource use and improve crop yields.
