Now an app to help farmers practice precision agriculture

[vc_row][vc_column][vc_column_text]~By T V Venkateswaran

New Delhi, June 14 (India Science Wire): Engineering students at Indian Institute of Technology Roorkee have developed a mobile app that can help farmers practice precision agriculture, particularly in application of precise amounts of fertilizers.

By determining health of the crops using hyperspectral imaging of crop leaves, the app could help in rational use of fertilizers. The development has won IIT Roorkee students the Ericsson Innovation Award 2017. Over 900 teams from 75 countries participated in the global contest for developing innovative ICT ideas on the theme of ‘Future of Food’.

Farmers apply fertilizer based on their experience rather than on any rational input. Therefore, if they chose not to apply fertilisers, perhaps they may be taking a risk and suffer economic losses. On the other hand, excessive application spoils the soil and damages the environment. “If only the farmers can know the health status of the plant, then they can make a more rational choice. The app developed by our students would be handy to the farmers. They would be able to know if the crops need fertilisers or not in just a snap,” says Prof Ajit Kumar Chaturvedi, Director, IIT Roorkee.

Named SNAP, the app uses a precision agriculture technology to determine the optimum fertiliser inputs for the crop and works on the principle of hyperspectral imaging of plant leaves. Spectral lines are like fingerprints that indicate presence or absence of a chemical by studying the light reflected by the leaf. Hyperspectral imaging combines conventional spectroscopy with imaging techniques to acquire both spectral and spatial information simultaneously for detecting physical, chemical, and biological attributes of the samples.

When the sunlight falls on a leaf, the reflected visible light and the near-infrared rays contain specific signals that tell about its chemical constituents. Water content, amount of macronutrients such as nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), as well as micronutrients such as sulfur (S), sodium (Na), iron (Fe), manganese (Mn), boron (B), copper (Cu), and zinc (Zn) and so on can be effectively measured using the hyperspectral imaging technology.

“The app uses mobile phone camera as the imaging device and hence could be profusely used in the field by the farmers,” pointed out Prof Chaturvedi.

The award winning team included Ekdeep Lubana, Anisha Godha Ankit Bagaria and Utkarsh Saxena with diverse expertise of electronics and communication, chemical and metallurgy. After an intense global competition, the team was one of the three global finalists to compete at Noble Museum in Stockholm, Sweden. The low-cost handheld imaging device for optimising fertiliser use in agricultural was declared the global winner and the team were awarded 25,000 Euro.

The jury was chaired by Sara Mazur, Head of Ericsson Research, had Caleb Harper, MIT Media Lab, Dr Catherine Mulligan, Imperial College London, Mattias Fyrenius, CEO Nobel Media, and Johan Jörgensen, Founder Stockholm FoodTech as members.

India Institute of Technology Delhi’s ICT product ‘Enigma’ that seeks to reduce weevil infestations in rice crop storage won the second place while  students of Aalto University, Finland who developed  ‘Foodgrid’, an attempt at minimizing the distance between farm and table by building a social and commercial platform to connect urban farmers, landowners with green space, and consumers won the third place.

Five soldiers lost their lives and several others were injured when an Army vehicle veered off the road and fell into a deep gorge in the Balnoi area of Mendhar, Poonch district, Jammu and Kashmir, on Tuesday, according to officials.

The incident occurred as the vehicle, part of the 11 Madras Light Infantry (11 MLI), was traveling from Nilam Headquarters to Balnoi Ghora Post. Reports indicate that the vehicle plunged approximately 350 feet into a steep gorge near its destination.

Upon learning of the accident, the Quick Reaction Team from 11 MLI rapidly mobilized to the scene to initiate rescue operations. The injured personnel received immediate medical attention, and efforts are currently underway to evacuate them for further treatment.

In a message on X, the White Knight Corps expressed their deep condolences for the tragic loss of five courageous soldiers, stating, “All ranks of #WhiteKnightCorps extend their deepest condolences on the tragic loss of five brave soldiers in a vehicle accident during operational duty in the #Poonch sector. Rescue operations are ongoing, and the injured personnel are receiving medical care.”

“Today at around 17:40 hrs (5.40 pm), an Army vehicle of 11 Maratha Light Infantry, which was on its way from from Nilam headquarters to Balnoi Ghora Post along the LoC, met with an accident near Ghora Post,” said officials.

This incident follows a similar accident last month, where one Army personnel died and another was injured when their vehicle skidded off the road and fell into a gorge in Rajouri district, Jammu and Kashmir. This crash, which occurred on November 4 near Badog village in Kalakote, resulted in Naik Badri Lal and Sepoy Jai Prakash suffering critical injuries; Lal ultimately succumbed to his injuries while in treatment.

On November 2, another tragedy struck when a vehicle skidded off a hilly road in Reasi district, claiming the lives of a woman and her 10-month-old son, while three others sustained serious injuries.

In Himachal Pradesh, a significant snowfall in the past 24 hours has resulted in four fatalities and the shutdown of approximately 700 electric transformers along with over 350 roads, including three national highways. This has left around 500 vehicles stranded, among which are more than 300 buses.

The snowfall, which began yesterday, has been recorded in various districts such as Kinnaur, Lahaul and Spiti, as well as the higher elevations of Shimla, Kullu, Mandi, Chamba, and Sirmaur.

On a positive note, the situation has attracted a large number of tourists heading to Shimla and nearby areas in hopes of enjoying a white Christmas. According to MK Seth, president of the Shimla Hotel and Tourism Stakeholders’ Association, hotel occupancy in the historic town has exceeded 70%, 30% higher than usual.

Tragically, four individuals lost their lives in accidents over the last day, with several others injured due to vehicles skidding in hazardous conditions. Key national highways connecting Attari to Leh, Sanj to Aut in Kullu, and Khab Sangam in Kinnaur to Gramphoo in Lahaul and Spiti are currently blocked.

Delhi Pollution: GRAP 4 revoked in capital, NCR as air quality improves

The Commission for Air Quality Management (CAQM) today revoked Stage 4 of the Graded Response Action Plan (GRAP) across Delhi and the National Capital Region (NCR). Nonetheless, measures under stages 1, 2, and 3 will remain in force to manage pollution levels. The GRAP 4 measures have been in effect in the entire NCR since December 16 after deterioration in air quality. 

This move follows after the Central Pollution Control Board (CPCB) reported an Air Quality Index (AQI) of 401 at 8 AM. The AQI on Monday fell into the severe category, measuring 403 at 7 am. Reportedly, AQI in several areas of the national capital was also recorded as ‘severe.’

Reports said, Anand Vihar recorded an AQI at 439, 456 at Ashok Vihar, 473 at Bawana, 406 at CRRI Mathura Road and 430 at Narela. Notably, an AQI between 0-50 is considered good, 51-100 is satisfactory, 101-200 is moderate, 201-300 is poor, 301-400 is very poor, and 401-500 is severe.

The GRAP 4 measures were implemented in Delhi after the air quality index (AQI) hit alarming levels on 16th December 2024. The Air Quality Index breached the 350 mark during the day, prompting the GRAP Sub-Committee to implement Stage-III measures. On the same day, by 10 PM, the AQI soared to 401, surpassing the severe plus category threshold. According to the Supreme Court instructions, Stage-IV measures were immediately introduced to tackle the crisis.

The apex court had earlier mandated precautionary measures, requiring Stage-III actions for AQI above 350 and Stage-IV for AQI exceeding 400. These directions were reiterated on 5th, 12th, and 19th December 2024, underlining the urgency to address Delhi’s air pollution.

As Delhi continues to battle hazardous air quality, the intensified measures under GRAP Stages I, II, and III will focus on curbing pollution sources and improving monitoring. Furthermore, residents are urged to remain cautious and adhere to guidelines issued by the authorities to mitigate the impact of air pollution on health and daily life.
