Coming soon - Soil sensor gets a square wave update

After pondering the Multi-Year Soil Sensor Thread over at https://zerocharactersleft.blogspot.com/2011/11/pcb-as-capacitive-soil-moisture-sensor.html we decided to make another prototype of our revised I2C soil sensor, this time we'll use the square wave filtering technique rather than the RC-rise-time system. We need a few more components to rectify/average the square wave signal, this is our rough draft. on the attiny816 we might be able to generate a 5 or 10MHz square wave. we also moved the AHT20 to be on a second set of pins we'll bitbang to read the temp/humidity. That way we can chain multiple sensors if desired.

Soil nutrient sensor & Soil testing equipment

Monitoring of soil NPK sensor

Nitrogen is the main component of protein. It plays an important role in the growth of stems and leaves and the development of fruits, and is the nutrient element most closely related to yield. Before the first panicle rapidly swells, the plant’s absorption of nitrogen gradually increases. So, soil nutrient sensor is very important to the plating.

Phosphate fertilizer can promote the differentiation of tomato flower buds and early flowering and fruiting. Promote seedling root growth and improve fruit quality. When phosphorus is deficient, the young shoots and roots grow slowly, the plants are short, the leaves are dark green, dull, and the back is purple.

Potassium can promote healthy plant stems and improve fruit quality. Enhance the cold resistance of plants and increase the sugar and vitamin C content of the fruit. As in the case of nitrogen and phosphorus. potassium deficiency symptoms first appear in old leaves. When potassium is insufficient, carbohydrate metabolism is disturbed. Photosynthesis is inhibited, and respiration is strengthened. Therefore, the plant’s ability to resist stress is weakened when potassium is lacking, and it is vulnerable to disease. The quality of the fruit is degraded and the coloring is poor.

Effect

Soil nutrient detector play an important role in the growth and development of crops. They are the components of many important organic compounds in crops. Or it can affect the growth and metabolism of crops widely in the form of enzyme activator. Any physiological and biochemical process in crops cannot be completed by a single element alone. Each element has its own physiological functions and interactions, and jointly undertakes various metabolic energy supply, which guarantees the normal growth of crops.

Soil Moisture Applications and Practices Using the JXCT Soil Moisture Sensor

Over the past ten years, environmental monitoring has become increasingly important. Environmental factors such as climate change, dwindling water resources, and threatened habitats are driving the need to monitor the environment and implement better policies to protect it. Many natural processes in the environment are driven by or in some ways related soil hydrological processes. Monitoring soil moisture conditions provides important information for the protection and in the understanding of local and regional water resources. The JXCT soil moisture sensor is the most advanced soil sensor commercially available and described below are application examples where the JXCT has been used to gather data.

Agriculture

Irrigation of crops represents 90% of the water used worldwide. Monitoring soil moisture in the root zone of crops will optimize irrigation. The benefits of optimizing irrigation scheduling with soil moisture sensor includes increasing crop yields, saving water, protecting local water resources from runoff, saving on energy costs, saving on fertilizer costs and increasing the farmer profitability.

Archeology

In arid parts of the world, ancient people farmed and irrigated crops to feed themselves and their livestock. In the desert southwestern US, Mesoamericans were able to grow crops in seemly waterless desert environments, and the irrigation practices of these ancient people remain a mystery. It is believed by some archeologists that the ancient Mesoamericans extracted water from clay confining layers for their crops. Soil moisture probes such as the JXCT are deployed in archeological sites to better understand the soil hydrology and to help us understand the day-to-day lives of our distant ancestors.

Biofuel Studies

For thousands of years, people have been growing corn and other crops to sustain the nutritional requirements of the population and livestock. Over the centuries, crops have been domesticated and changed genetically from their wild counterparts for this specific purpose. Now that biofuels are a possible alternative energy source, crops need to be cultivated in order to produce ethanol. In recent years, a new branch of agronomy emerged called biomass studies. Agronomists that specialize in biomass look at new ways to ferment crops to increase the ethanol yields. The goal is to be able to produce ethanol from not only the fermentation of the fruit, but the stems, leaves, and roots. Soil moisture sensor is used in this research to characterize the hydrological requirements of the biomass crops.

Dust Control

Poor air quality from particulates in air can have negative consequences to not only human health but regional ecosystems. Vehicular traffic on unpaved roads can lead to major dust problems. In areas of the Southwestern US, the soil is naturally abundant in several types of asbestos. Local officials close unpaved roads based on soil moisture conditions to prevent dangerous dust situations.

Soil temperature and humidity sensor

The soil temperature and humidity sensor is composed of two sensors. Namely a soil moisture sensor and a soil temperature sensor. The soil temperature and humidity sensor is related to the growth of crops and is the basis of farmland operations.

The soil temperature sensor is a soil temperature sensor that can monitor the temperature of the soil. The atmosphere and the water, and is used in experiments and scientific research. The soil temperature is closely related to the growth and development of crops. The decomposition of fertilizers and the accumulation of organic matter. It is an important environmental factor in agricultural production. Soil temperature is also an extremely important factor in the formation of microclimate. So the measurement and research of soil temperature is an important part of microclimate observation and agrometeorological observation.

Soil moisture sensor is also known as: soil moisture sensor, soil moisture sensor, soil moisture sensor. It is mainly used for measuring soil volumetric water content, monitoring soil moisture, agricultural irrigation and forestry protection.

Capacitive soil moisture sensor

The sensitive element of the capacitive soil moisture sensor is a humidity sensitive capacitor. And the main material is generally metal oxide and high molecular polymer. These materials have a strong adsorption capacity for water molecules. And the amount of water absorbed varies with the change of environmental humidity. Because water molecules have a large electric dipole moment. The permittivity of the material changes after water absorption, and the capacitance value of the capacitor also changes. The change of the capacitance value is converted into an electrical signal, and then the humidity can be monitored. Humidity-sensitive capacitors are generally made of polymer film capacitors. When the environmental humidity changes, the dielectric constant of the humidity-sensitive capacitor changes, and its capacitance also changes. The capacitance change is proportional to the relative humidity. This feature can measure humidity. The humidity sensing media of commonly used capacitive soil moisture sensors mainly include: porous silicon. Polyphthalimide, in addition to polysulfone (PSF), polystyrene (PS), PMMA (linear, cross-linked, plasma polymerization).

Resistance type soil moisture sensor

The sensitive element of the resistive soil moisture sensor is a humidity sensitive resistor. And its main materials are generally dielectrics, semiconductors, porous ceramics, etc. These materials have a strong adsorption of water. After absorbing moisture, the resistivity/conductivity will change with the change of humidity. So that the change of humidity can cause the change of the resistance of the humidity sensitive resistor. And the change of the resistance can be converted into the required electricity. Signal. For example, an aqueous solution of lithium chloride forms a thin film on the substrate. As the water vapor content in the air increases or decreases, the thin film absorbs moisture and dehumidifies. The salt concentration in the solution decreases and increases. And the resistivity increases and decreases accordingly. The resistance between the two stages increases and decreases. Another example is the porous ceramic humidity sensor. The ceramic itself is composed of many small crystal particles. And most of the pores are in communication with the outside world. The pores can absorb water molecules and cause changes in ion concentration. Which leads to changes in resistance between the two poles.

Ionic soil moisture sensor

Ion-sensitive field effect transistor (ISFET) is a semiconductor biosensor, which was developed by P. Invented by Bergeld. The ISFET directly contacts the ion buffer solution in the measured solution through different sensitive film materials on the grid. And then the ion concentration in the solution can be measured.

The schematic diagram of the structure model of the ion-sensitive soil moisture sensor is shown in the figure below. Ion sensitive devices are made. The ion selective membrane (sensitive membrane) and the converter are composed of two parts. The sensitive membrane is used to identify the type and concentration of ions. And the converter converts the information sensed by the sensitive membrane into electrical signals. The ion-sensitive field effect tube makes a layer of sensitive film on the insulating grid. And the types of ions detected by different sensitive films are also different, so that it has ion selectivity.

Using EC Sensors in Precision Agriculture

Summary:

Soil conductivity sensors, also known as EC sensors, are used to measure soil conductivity widely in agricultural production. However, there is still confusion about what the readings mean and how they can be used in precision agriculture.

To what extent can EC sensors be used for ‘precision fertilization management’? In fact, ‘Soil EC’ may refer to different types, or methods, of EC readings, each with its own significance.This article will explore the meaning of the different EC measurements and evaluate their applicability for precision agriculture.

Measurement method:

The electrical conductivity is the ability of a material to transmit electrical current. The question is, therefore, which medium is being measured and how can the reading be interpreted and used? The most commonly used EC measurement in precision agriculture is the soil bulk EC, or soil apparent EC (ECa). This soil EC correlates with various soil properties, such as soil texture and water holding capacity. Sandy soils will have a lower EC reading than clay soils.

Mapping the ECa within a field provides additional information on the soil variability within that field and on year-to-year trends, such as salinization and compaction of the soil. Such information can aid in deciding on variable rates of herbicides and nitrogen fertilizer, as their application efficiency depend on soil texture. For instance, a split application of nitrogen may be required in light-textured soils.

If correlated with yield maps, ECa can also give an idea on the nitrogen rate to apply, although such correlation does not always exist, and many additional agronomical considerations must be taken into consideration. ECa is, therefore, one more tool that can be used to better understand soil variability in the field. However, it cannot replace traditional soil testing. Other methods to evaluate electrical conductivity of soil focus on measuring the EC of the soil-solution, hence its salinity. The difference between these methods is mainly the moisture state of the soil. The electrical conductivity of the soil-solution changes continuously, depending on the moisture content of the soil. Therefore, for standardization, all EC measurements must be taken at the same moisture content.

The most acceptable moisture content is the moisture of ‘saturated paste’, also referred to as ‘EC of the saturated paste extract’. Most references in the literature, such as tolerance to salinity of different crops, relate to the EC of the saturated extract, denoted as ECe. ECe gives an indication of the soil salt content. It can be used to estimate whether there is excess of salts in the soil. However, it does not imply exactly which salts and nutrients are present. Unlike the apparent electrical conductivity of the soil, ECe cannot be measured directly in the field using sensors, and it must be measured at the laboratory. There are, though, mathematical models that attempt to correlate between ECa and ECe.

To summarize, EC sensors in precision agriculture are a valuable tool for better understanding variability and trends in the soil. This is especially true for soil EC mapping and to a much lesser extent to stationary single soil sensors. However, precise fertilization management is a complex process, that takes into consideration multiple variables and parameters, well beyong beyond EC alone.

What are the effects of using a soil analyzer?

For farmers, the quality of the soil affects whether the food crops can be harvested, and the soil has a vital function in the growth and development of the crops. However, many villagers do not know their own soil, and many often blindly follow the crowd, plant at will, without overall planning. This kind of personal behavior usually results in a large price difference between the food crops planted and the estimated price in the sales market, resulting in serious losses. There are also some farmers, although they make do with the guarantee, they have not been able to change the appearance of their daily lives based on planting food crops, and only meet the main requirements of daily life. The use of soil analyzers allows farmers to better understand their own soil, effectively fertilize them, and promote the growth and development of crops, which bodes well.

Following the rapid development trend of modern agriculture, the characteristics of soil and fertilizer efficiency have been harmed. Farmland regulations, fertilizer investment, watering and other enterprise production management strategies are all the key reasons for the mutation of soil genes. The digestion and absorption of nutrients by crops and the movement of nutrients in the soil model are all indoor spatial genetic mutations that cause soil characteristics. The uneven use of chemical fertilizers can also increase the evolutionary level of soil nutrients, and the transformation of nutrients can apply soil fertilizers. Nutrient tachometer. The characteristics of soil not only change with the difference of indoor space conditions, but also evolve with time. Elements such as parent material, landforms, and human activities all use time elements to contribute to the whole process of the transformation of the spatial layout of soil characteristics.

The soil fertility efficiency refers to the characteristics of the soil and other changes during the development of green plants, such as the standard of green plant participation, the quality of soil water permeability, and the application of equipment to test the nutrients and moisture components in the soil, and soil maintenance Water and nutrient work capacity, thermal conditions, cultivability, potential nutrient conversion standards, harmfulness of green plants, etc.

Nowadays, in the process of planting food crops, farmers attach great importance to the measurement of soil nutrients. Because only the application of soil analyzers to test soil nutrients and the completion of scientific research and fertilization can obtain high-yield, high-quality crops, food crops The necessary nutrients are provided by the two levels of soil and chemical fertilizers. The nutrients required for crops are calculated based on the production volume of the plan. The nutrient content of chemical fertilizers is determined. Only the reasonable nutrient content of the soil is unclear.

Application of soil sensor in agriculture

Soil is an important natural resource and the material basis of agricultural production. The ability to accurately monitor the parameters and quality of the soil environment is of great significance for guiding the development of agricultural resources and agricultural production. In recent years, special attention has been paid to the protection of soil resources and the construction of the ecological environment. Monitoring the soil environment has become the daily work of the agriculture and environmental protection departments.

There are three traditional methods for monitoring farmland soil moisture temperature, conductivity, pH, and npk: indirect measurement method, direct measurement method, remote sensing and field GPS positioning method. However, these three monitoring methods are either cumbersome and inconvenient to operate; they are too simple to ensure accuracy; or they are time-consuming and costly. All in all, it is lack of timeliness and accuracy, and it is difficult to realize real-time monitoring of farmland environment. In view of this, in order to effectively improve the detection technology and monitoring methods, as well as increase the speed and accuracy of monitoring, it is necessary to use the current advanced five-pin soil sensor. The five-pin soil sensor, also known as the conductivity soil temperature and moisture PH npk 7 in 1 sensor, is a sensor device launched for more convenient monitoring of the temperature, humidity, conductivity, and pH value in the soil.

7 in 1 soil nutrient sensor is suitable for all kinds of soil. It is an important tool for observing and studying the occurrence, evolution, improvement and water and salt dynamics of saline soil. Can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum potting, and completely waterproof. Without destroying the undisturbed soil structure, accurately measure soil temperature, moisture, conductivity, PH value, and NPK. The sensor is suitable for soil moisture monitoring, scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grassland pastures, soil rapid testing, plant cultivation, sewage treatment, precision agriculture and other occasions for temperature and humidity, electrical conductivity, PH value testing.

The 7 in 1 soil nutrient sensor data upload method is convenient for managers to understand the soil environment in time. The conductivity, soil temperature and moisture NPK PH7 in one sensor can be connected to the environmental monitoring host through 485 wiring and uploaded to the environmental monitoring cloud platform to monitor the soil conditions in real time. It can also coordinate with related soil data to control the irrigation system and other related equipment. Once one of the soil temperature, moisture, conductivity, and PH value exceeds the set upper and lower limits, an alarm will be triggered to notify the management staff for processing.

The installation method of the soil sensor: Quick measurement method: select a suitable measurement location, avoid rocks, ensure that the steel needle does not touch hard objects, throw away the surface soil according to the required measurement depth, and maintain the original tightness of the soil below , Hold the sensor vertically and insert it into the soil. Don't shake it left and right when inserting. It is recommended to measure multiple times within a small range of a measuring point to find the average value. Buried measurement method: Vertically dig a pit with a diameter> 20cm, insert the transmitter steel needle horizontally into the pit wall at a predetermined depth, and fill the pit tightly. After a period of stability, it can be carried out for several days, months or even more. Long-term measurement and recording.

As one of the three foundations of information technology, sensor technology is a key technology since entering the 21st century. Informatization and intelligence are the focus of the future development of agricultural science. How to cooperate with the Internet of Things technology to quickly and effectively obtain soil information, even though the important research direction of soil science, is also an important technical support for traditional soil environmental monitoring to modern soil environmental monitoring.
