By measuring the thickness of the leaf with the help of a plant-based sensor and the ability to store the electrical charge of the device (common electrical power), it can be checked when the exact requirement of the water is required. To measure this accurately, Penn State University researcher Amin Afzal has developed this sensor. So at the same time, the thickness of the leaf and the power of the electric power can be measured at the same time. This research has been published in the American Society of Agricultural and Biological Engines Research.
It is difficult to keep the water under constant dry inspection in dry areas or dry areas. Considering the quantity of soil moisture in conventional method or the amount of water evaporator from the soil and the soil, the timing of irrigation is decided. But there are problems with it. The sensor has been developed to overcome it. Due to this new technology, there is a need for water to plant. It is possible to irrigate the required time. Alternatively, the use of water increases efficiency.
Such amendment
This experiment is done in the tomato crop planted in organic soil in the growth chamber. For this, a constant temperature is kept for 11 days. Sensors were measured to measure the volume of the soil. Water management was done in the first three days so that soil moisture content is high. After that stopped giving water for eighteen days.
6 pages of tomato seedlings coming directly to the light were selected. The signals are placed on the leaves leaving the main vein and part of the stomach. The entries were taken every five minutes.
Found Conclusions
The amount of soil moisture is observed for the maximum level and the change in the page at the minimum level necessary for the tree's survival (as it is called the wilting point). It did not find any significant changes.
When the soil moisture content is below the welding point, there are significant changes in the thickness of the leaf.
In the last two days of the experiment, the thickness of the land reached up to 5% till the thickness of the page was stable.
Individual power shows the ability to store the electrical charge. Which remains almost constant at least in the darkest price. In the light, it means that it grew rapidly during the day. This means that the common electrical power of the page shows the function of photosynthesis.
When the amount of soil moisture is below the welding point, the fluctuations in daily electrical power consumption are decreasing.
When the level of soil humidity dropped below 11%, the fluctuation in the common power stopped altogether. In essence, the impact of water stress on common electrical power is reflected in photosynthesis.
These sensors work directly in plant tissues. If more research is done in future, the use of this sensor will improve the irrigation water use efficiency. This research received the first prize in the College of Agricultural Sciences as well as the Springboard competition and received a grant of 7500 donors for developing this concept.
The sensor works like this
Leaves increase due to the availability of water, which means that thickness of the leaves increases, due to water shortage or dehydration. There is a complex process behind the relation between the page's electrical capacitance and water quality. Afzal says that
The difference in the electrical content of the leaves also changes if the water conditions and surrounding light differ. This means that the thickness of the page and analysis of the diversity of the electrical commonplace shows the state of water.
The sensor will send the exact information of the plant water to the central unit of the field. Therefore, it will be able to know the timing of watering the crop. The sensor, the central unit, and the irrigation systems run wirelessly or through the battery.
This system can be run through a smartphone app
