TECHNICAL FIELD
[001] The technical field of the invention pertains to advanced agricultural systems specifically designed for optimizing cultivation in urban and arid environments. It focuses on integrating hydroponic and aeroponic techniques to enhance nutrient and water efficiency while addressing the challenges associated with reduced soil quality and water scarcity. The invention combines the Dutch bucket hydroponic method, which uses drip irrigation for larger plants, with aeroponics, which employs misting to deliver nutrients. This hybrid system is engineered to be space-efficient and scalable, making it suitable for both commercial and small-scale urban farming operations. The technology aims to provide a sustainable and resource-efficient alternative to traditional soil-based agriculture.
BACKGROUND
[002] The rapid expansion of urban areas and industrialization has significantly reduced the availability of arable land for traditional agriculture. This urban sprawl, coupled with the increasing global population, has intensified the demand for food. In regions like India, where both population density and urbanization are high, conventional agriculture struggles to meet the food requirements due to the reduction in farmland. This has led to the exploration of alternative farming methods that can operate efficiently in limited spaces.
[003] The decline in soil quality and increasing water pollution are critical issues affecting traditional agriculture. Soil degradation caused by overuse of chemical fertilizers, deforestation, and erosion has led to diminished agricultural productivity. Simultaneously, water pollution from industrial activities and agricultural runoff has further compounded the problem, rendering many water sources unsuitable for conventional farming. These environmental challenges necessitate the development of soilless cultivation systems that do not rely on traditional soil and can function effectively in compromised water conditions.
[004] Hydroponic and aeroponic systems represent advanced soilless farming techniques designed to address some of the limitations of conventional agriculture. Hydroponics involves growing plants in a nutrient-rich solution without soil, allowing for controlled nutrient delivery and efficient water use. Aeroponics takes this a step further by misting plant roots with a fine nutrient solution, promoting rapid growth and resource efficiency. Combining these methods into a single integrated system could offer a robust solution for space-constrained and resource-limited environments.
[005] US20240245018A1 describes a spiral growing system housed in a vertically elongated silo chamber. This system features a continuous spiral track that guides crops through a growing space. While innovative in its vertical farming approach, this patent does not integrate hydroponics or aeroponics, focusing instead on a single growing mechanism. The research gap here is the lack of combined hydroponic and aeroponic systems that optimize both space and resource use in a unified setup.
[006] Existing hydroponic systems, such as those described in patents like US7229271B2, which outlines a modular hydroponic growing system, address the need for efficient nutrient delivery but do not incorporate aeroponics. Similarly, aeroponic patents, such as US6217492B1, detail misting techniques for plant growth but are not combined with hydroponic methods. The gap lies in the integration of these technologies to maximize both nutrient and water efficiency in a compact, scalable system.
[007] The Dutch bucket hydroponic system, detailed in various patents, including US5857885A, employs a drip irrigation approach to deliver nutrients to plants growing in a soilless medium. This method is effective for larger plants and offers improved water and nutrient efficiency compared to traditional methods. However, it lacks the misting component of aeroponics, which can enhance growth rates and resource utilization.
[008] Combining Dutch bucket hydroponics with aeroponics into a single system addresses the limitations of each method when used in isolation. This hybrid approach leverages the strengths of both techniques: the controlled nutrient delivery of hydroponics and the efficient misting of aeroponics. Such integration is not extensively covered in existing patents, highlighting a significant research gap in optimizing both nutrient and water usage in soilless cultivation systems.
[009] The innovation presented fills a critical gap by offering an integrated hydroponic and aeroponic system designed for urban and arid environments. By combining these technologies, the system not only maximizes space utilization but also enhances water and nutrient efficiency, making it a viable solution for addressing modern agricultural challenges. The novel approach of this invention supports sustainable agriculture in areas where traditional methods are impractical, providing a scalable and adaptable alternative for various cultivation needs.
SUMMARY
[010] The invention introduces an advanced cultivation system combining Dutch bucket hydroponics with aeroponics to address the challenges of modern agriculture, particularly in urban and arid environments. The system is designed to optimize nutrient and water efficiency, making it suitable for areas with limited fertile soil and water scarcity. By integrating these two soilless farming techniques, the system enhances space utilization, enabling dense plant growth in compact areas, which is ideal for urban settings where traditional agriculture is not feasible.
[011] The Dutch bucket hydroponics component of the system features a drip irrigation setup that delivers a precise nutrient solution directly to the plant roots. This approach is particularly effective for larger plants, allowing for controlled growth conditions and efficient resource use. The recirculating reservoir associated with this method further improves water efficiency by collecting and reusing excess nutrient solutions.
[012] Incorporating aeroponics, the system utilizes vertical PVC pipes and a misting mechanism to provide a fine mist of nutrient solution to plant roots. This technique promotes rapid plant growth and maximizes nutrient absorption. The aeroponic component complements the Dutch bucket system by offering an additional layer of nutrient delivery that enhances overall system efficiency.
[013] The combined hydroponic and aeroponic setup is modular and scalable, making it adaptable for both small-scale urban farms and large commercial operations. Its space-efficient design allows for the cultivation of multiple plant varieties in a compact footprint, which is advantageous in densely populated or resource-limited areas.
[014] Overall, the integrated system addresses key issues such as soil degradation, water pollution, and increasing food demand. By improving nutrient and water utilization, increasing yield potential, and promoting sustainable practices, this invention offers a viable alternative to traditional soil-based farming and supports more resilient and efficient agricultural practices in challenging environments.

[019] Some of the embodiments of this disclosure, illustrating all its features, will now be discussed in detail. The words "comprising," "having," "containing," and "including," and other forms thereof, are intended to be equivalent in meaning and be open-ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items or meant to be limited to only the listed item or items.

[020] The invention introduces a sophisticated integrated hydroponic and aeroponic system designed to optimize plant cultivation, especially in urban and arid environments. By merging Dutch bucket hydroponics with aeroponics, this system enhances nutrient and water efficiency, offering a sustainable alternative to conventional soil-based agriculture. The Dutch bucket method utilizes a drip irrigation approach, where nutrient solutions are delivered directly to plant roots, while the aeroponic component employs misting to provide essential nutrients. This combination addresses the challenges of limited space and water scarcity, providing an innovative solution for modern agricultural needs.
[021] The Dutch bucket hydroponics component comprises twelve plastic buckets arranged on a platform. Each bucket is equipped with a drip irrigation system, featuring arrow drippers with a flow rate of 2.3 liters per hour. These drippers ensure that a precise amount of nutrient solution is delivered to the plant roots, promoting optimal growth. The nutrient solution that is not absorbed by the plants is collected and returned to a recirculating reservoir. This design minimizes nutrient and water waste by allowing the solution to be reused, thus significantly improving water efficiency and reducing operational costs associated with constant nutrient replenishment.
[022] In one embodiment it is provided that, the aeroponic section of the system is designed with three vertical PVC pipes, each with an 8-inch diameter, which contain a total of 34 net pots. These vertical pipes are equipped with a misting system consisting of three perforated pipes that disperse a fine mist of nutrient solution directly onto the plant roots. This misting technique ensures that the roots receive an adequate supply of nutrients and oxygen, fostering rapid and healthy plant growth. The aeroponic system complements the hydroponic setup by providing an additional method of nutrient delivery that enhances overall system efficiency.
[023] A large nutrient tank is a central feature of the system, essential for maintaining a steady supply of nutrient solution for both hydroponic and aeroponic components. An 18W pump is used to transport the nutrient solution from the tank through a network of delivery pipes to the various parts of the system. Additionally, a more powerful 55W pump is employed to ensure that the nutrient solution is effectively circulated and distributed throughout the system. This dual-pump setup guarantees that the plants receive a consistent and adequate supply of nutrients, supporting optimal growth conditions.
[024] In one embodiment it is provided, that the delivery and return flow system plays a crucial role in maintaining the efficiency of the integrated system. Delivery pipes transport the nutrient solution from the tank to both the Dutch bucket and aeroponic components. Excess solution that is not utilized by the plants is captured by return flow pipes and directed back to the reservoir. This closed-loop system ensures that the nutrient solution is continually recirculated, minimizing waste and maintaining a stable nutrient environment for the plants.
[025] The compact and space-efficient design of the system allows for substantial plant cultivation in a relatively small area. Specifically, the setup supports the growth of 24 capsicum plants using the Dutch bucket method and 34 clusters of mint leaves via aeroponics within just 1.45 square meters. This space-saving feature is particularly advantageous for urban environments, where available land is often limited and costly. The ability to grow a significant number of plants in a confined space makes the system an ideal solution for urban agriculture.
[026] The system utilizes durable materials, such as high-quality plastic for the Dutch buckets and corrosion-resistant PVC for the vertical aeroponic pipes, which ensures long-term resilience, easy maintenance, and effective cleaning. This choice of materials enhances the system's durability and reliability, allowing it to withstand the demands of continuous use in various environmental conditions.
[027] Implementation of this integrated system has demonstrated notable improvements in both nutrient and water efficiency. Compared to traditional soil-based farming methods, the system's recirculating design greatly reduces waste of nutrient solutions and water. This results in more efficient resource utilization and lower operational costs. Additionally, the system's ability to support rapid plant growth and higher yields contributes to increased overall productivity, addressing the growing food demands of modern populations.
[028] The advantages of the system extend beyond its operational efficiency. Its modular and scalable design allows for easy customization and expansion, making it suitable for a range of applications from small urban farms to large commercial greenhouses. This flexibility ensures that the system can be adapted to meet various agricultural needs and operational scales. The ability to function effectively in environments with poor soil quality and water scarcity further underscores the system's versatility and practical value.
[029] In discussions about the practical applications of the system, its integration of hydroponic and aeroponic methods emerges as a significant innovation in modern agriculture. The system provides a comprehensive solution to key challenges such as limited space and resource scarcity, supporting sustainable agricultural practices. By improving nutrient and water efficiency, the system offers a promising alternative to traditional farming methods, particularly in areas where conventional approaches are impractical or unsustainable.
[030] The environmental benefits of the system are also noteworthy. By reducing reliance on traditional soil-based agriculture and minimizing resource waste, the system supports more sustainable farming practices. Its ability to operate effectively in challenging conditions, such as urban areas and arid regions, highlights its potential to contribute positively to environmental conservation and resource management. Overall, the integrated hydroponic and aeroponic system represents a significant advancement in agricultural technology, providing a practical and eco-friendly solution for contemporary farming needs.
[031] Advanced monitoring and control mechanisms are incorporated into the system to maintain optimal growing conditions. Sensors or manual adjustment options regulate nutrient concentration, pH levels, and misting intervals, allowing for precise management of the growing environment. This capability supports improved plant health and productivity, making the system adaptable to different plant species and growth requirements.
[032] Referring to Figure 1, depicts an advanced hydroponic and aeroponic cultivation system designed for space efficiency and effective resource utilization. It features twelve Dutch buckets, arranged neatly on a raised platform, each equipped with a drip irrigation system that delivers a controlled flow of nutrient solution directly to the plant roots. Adjacent to these buckets are three vertical PVC pipes, each with a diameter of 8 inches, housing a total of 34 net pots. These pipes are connected to a misting system that emits a fine nutrient mist to nourish the plant roots within the aeroponic setup. The nutrient solution is stored in a large tank, prominently placed near the system, and is circulated through delivery pipes by an 18W pump, while a more powerful 55W pump ensures thorough nutrient distribution. The image also illustrates a network of delivery and return flow pipes that facilitate the transport and recirculation of the nutrient solution between the tank, the Dutch buckets, and the aeroponic pipes. The entire setup is compact and designed to maximize cultivation efficiency within a limited space.
