Description

[0001] INSTANTANEOUS AND VOLUMETRIC HANDLING AND CONTROL DEVICE FOR FIRST-USE OR RECOVERED WATER AND ITS NUTRIENTS FOR CROP IRRIGATION AND REGENERATION

[0002] FIELD OF INVENTION

[0003] The present invention falls within the field of agriculture in general, and in particular relates to equipment, devices, and systems for controlling water flow for irrigation in cultivated land and for discharging water on agricultural land for other purposes. More specifically, it refers to a device for the instantaneous and volumetric management and control of primary water and, where applicable, the complete utilization of reclaimed water and its nutrients for irrigation, precision fertigation in crops, soil regeneration, and / or subsurface aquifer recharge.

[0004] BACKGROUND OF THE INVENTION

[0005] Water is one of the most critical resources in agriculture, and its efficient use is key to ensuring crop sustainability, especially in regions affected by water scarcity. A lack of water in agricultural soils generates a series of problems that affect both crop productivity and the health of the agricultural ecosystem; this is also known as water stress, which directly impacts the ability of plants to grow and develop properly.

[0006] Insufficient water prevents plants from absorbing essential nutrients from the soil, as water is the primary medium through which nutrients dissolve and are absorbed by the plant's root system. Water scarcity also impairs photosynthesis, reducing CO2 uptake and consequently hindering growth, flowering, and fruit development.

[0007] On the other hand, it is known that agricultural soils with low moisture tend to become compacted. This occurs because the soil structure becomes more rigid and compact, denser in the absence of water, which hinders root development and reduces water infiltration from future irrigation or rainfall.

[0008] The lack of water in agricultural soils also reduces the cohesion between soil particles, making them more vulnerable to erosion by wind or surface water. This erosion removes the most fertile layers, rich in nutrients, minerals, and microelements, reducing soil quality and affecting its capacity to support future crops. The loss of fertile soil also increases the need for fertilizer, which can lead to higher costs and environmental damage, as well as salinization of agricultural lands. This salinization occurs because of the accumulation of salts in the soil due to poor irrigation or excessive evaporation. These salts accumulate on the surface in the face of water scarcity, severely affecting soil fertility and the ability of plants to absorb water and nutrients.

[0009] Water is also essential for maintaining a healthy population of soil microorganisms, which are responsible for decomposing organic matter and recycling essential nutrients for crops. A lack of water reduces the presence and activity of these microorganisms, deteriorating soil quality and the ecosystem's ability to regenerate.

[0010] In very extreme cases, prolonged drought and the lack of proper water management can lead to desertification, which is the irreversible degradation of the soil, losing its structure, water retention capacity, fertility and organic matter, transforming into sterile land making agriculture unviable.

[0011] Additionally, it is estimated that of the more than 800 km 3 of wastewater generated worldwide, more than 600 km 3Many of these wastewaters, primarily in developing countries, go untreated, polluting lakes, rivers, and seas, mainly with pathogens (bacteria, viruses, and parasites) and nutrients (nitrogen and phosphorus). This results in the deaths of nearly 900,000 people annually and the eutrophication of water bodies, with severe consequences for ecosystems. One reason why countries with very limited resources do not invest in wastewater treatment is that they prioritize their resources on more basic needs, such as providing water and food.

[0012] Therefore, it is important to have irrigation devices, systems and equipment that allow, in addition to emitting focused and directed irrigations to the root systems of cultivated plants, fertigation of crops, programming discharges and directing volumes of water and nutrients in soils for their regeneration, trapping nutrients in the surface layers and infiltrating the excess volumes free of nutrients through a managed recharge of the aquifer carried out in a subsurface manner.

[0013] Regenerative irrigation is a nature-based solution that aims not only to optimize the use of water and nutrients for crops, but also, when using reclaimed wastewater with nutrients for agriculture, to use the excess nutrients to regenerate and improve soil health, and the excess water, now free of nutrients, to recharge aquifers with high-quality, low-cost water.

[0014] Over the years, several irrigation systems have been developed aimed at optimizing water use, reducing waste, and increasing agricultural productivity.

[0015] The main existing irrigation systems are gravity irrigation, whereby water flows through canals or furrows to the agricultural fields; however, it has low efficiency due to evaporation and surface runoff, which also generate erosion in the farmland; it is estimated that 50% to 60% of the water is lost before reaching the plants; another type of irrigation is sprinkler irrigation, which directs rainwater through systems of pipes and sprinklers specially designed to spray water onto the farmland and although it is more efficient than gravity irrigation, it also suffers losses due to evaporation and wind, which reduces its effectiveness;Another type of irrigation is drip irrigation, which is a more recent technology, where water is delivered directly to the roots of the plants through drippers connected to irrigation tapes connected to a pressurization system that eliminates evaporation and runoff, avoiding the use of excess water. The system can have an efficiency of up to 95% and is associated with a more rational use of water, in addition to allowing fertigation.

[0016] Other emerging technologies include precision irrigation systems, which focus on leveraging technologies such as soil moisture sensors, software-controlled automated irrigation systems, and scheduling systems, along with satellite imagery, drones, or machine vision using camera systems, to monitor moisture in agricultural fields. However, although modern irrigation technologies have proven effective, their adoption remains limited in many regions due to high initial costs, a lack of operational training, and the necessary infrastructure for implementation.

[0017] On the other hand, climate change presents a significant challenge. As droughts become more frequent and intense, the demand for irrigation water increases while its availability decreases drastically. This also creates a demand for improved technology that optimizes irrigation water use.

[0018] As nations face increasing challenges related to water availability, efficient irrigation systems will not only contribute to greater water sustainability, but will also have a significant impact on water conservation and food security.

[0019] The present invention aims to provide a device for the instantaneous and volumetric management and control of virgin or reclaimed water for precision fertigation, soil regeneration, and / or subsurface aquifer recharge using soils rich in organic matter and life as a filtering and nutrient-capturing element based on nature. This addresses the problems with conventional systems regarding inefficiency in irrigation and food production, soil loss and desertification resulting from the leaching of the soil's organic layer and the agrochemicals traditionally used, and the decreased permeability of the remaining inert and compacted soils, which in turn do not infiltrate or retain moisture in the soil, much less in the aquifer, reinforcing a vicious cycle that is sometimes impossible to reverse without human intervention.

[0020] A search was conducted to determine the closest prior art, and the following documents were found.

[0021] Patent MX 279524 B, belonging to Francisco Xavier Valdés Simancas, a co-author of this application, was found. Filed on October 24, 2006, and granted on September 8, 2010, it discloses a device and method for controlling agricultural fertigation using an encrypted key. It provides a comprehensive irrigation control system with a control module (12) that allows the user to connect a smart key (13). This single module addresses the farmer's needs for measuring and supplying water, including the dosage of fertilizer used in irrigation.The use of a pre-authorized electronic key allows the optimal amount of water for the specific crop to reach the plot, as determined by the analysis of certain variables that influence that specific area. It does not use electricity from the public grid for its operation and has several measurement and control elements grouped in a cabinet for protection from the weather and vandalism that can occur in the field. This cabinet has two separate compartments: one for administration, accessible only to authorized personnel, and another for the user to operate the irrigation system. However, this device and method only perform a limited portion of the functions of the device in the present invention and lacks the capacity to integrate all the variables into a single-device solution. Furthermore, its structural configuration, drive elements, and function differ significantly from those of the present invention.

[0022] Patent application US11805740B2 by Periard Larrivee Yann and Pelletier Vincent, dated September 25, 2020, was located, disclosing a method and system for regulating plant irrigation in a crop field. The method comprises obtaining soil water tension (SWT) and / or soil water content (SWC) data for a crop field. The SWT and / or SWC data are segmented into three segments. A respective line of best fit is determined for each of the three segments. The intersections of the lines of best fit are used to determine an irrigation start threshold and an irrigation stop threshold. Devices controlling irrigation of the crop field must start or stop irrigation based on the irrigation start threshold and the irrigation stop threshold.

[0023] However, it focuses more on electronic control systems and is based on an automated control system to regulate the irrigation of plants in a crop field, the system being communicatively coupled to: one or more monitoring sensors to monitor the hydrodynamic conditions in the given crop field, and one or more controllable devices that can operate to irrigate the given crop field; the system comprising at least one processor, and memory that stores a plurality of executable instructions that, when executed by the at least one processor, cause the system to retrieve soil water tension (SWT) data and / or soil water content (SWC) data, corresponding to the crop field, recorded by one or more monitoring sensors; segments the SWT and / or SWC data into three segments; determines, for each of the three segments, a respective line of best fit;determines a first intersection between the line of best fit for the first segment and the line of best fit for the second segment; determines a second intersection between the line of best fit for the second segment and the line of best fit for the third segment; stores the first intersection as an irrigation stop threshold representative of a desired irrigation endpoint; stores the second intersection as an irrigation start threshold representative of a desired irrigation start point; and monitors the SWT and / or SWC data received from one or more monitoring sensors, and in response to a determination that the SWT and / or SWC reaches the irrigation start threshold, causes one or more controllable devices to start or increase irrigation of the crop field;and in response to a determination that the SWT and / or SWC has reached the irrigation stopping threshold, cause one or more controllable devices to stop or reduce irrigation of the crop field.;

[0024] However, said method and a system for regulating the irrigation of plants in a crop field only perform a limited part of the functions of the device in the present invention, but do not have the mechanical components, arrangement, configuration and operating components that allow the regulation of flows, volumes and water dosage control and its structural configuration, drive elements and function differ significantly from the present invention.

[0025] Given the need for a device for the instantaneous and volumetric management and control of first-use or reclaimed water with nutrient preservation for precision fertigation, soil regeneration, and / or subsurface recharge of high-quality, low-cost water to aquifers, the present invention was developed. It serves as an interface between cutting-edge technologies for calculating irrigation depths, with the aim of achieving highly productive and efficient agriculture, as well as the controlled and quantified delivery of water to fields and agricultural plots. This is combined with tools for measuring climatological variables and humidity and nutrient data at different depths in real time, which generates calculations through algorithms complemented by high-precision artificial intelligence to determine the exact amount of water and nutrients necessary for optimal crop growth.Soil regeneration and its capacity to trap nutrients to infiltrate high-quality, nutrient-free water into the aquifer for later use.
