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.

Union Home Minister Amit Shah on Saturday praised Dharmendra Pradhan’s decision to step down as Union Education Minister, saying the move reflected the Bharatiya Janata Party’s commitment to placing the nation and students above any political position.

In a post on X, Shah said that for BJP workers, the country, its youth and students are more important than any office. He described Pradhan’s resignation as an example of the party’s guiding principle of prioritising national interest over personal ambition.

Shah highlights government’s focus on exam reforms

Amit Shah said the Narendra Modi-led government respects the sentiments of students and remains committed to strengthening the examination system following concerns over alleged paper leaks.

He said the Centre has introduced strict measures to ensure severe punishment for those involved in examination paper leaks and expressed confidence that these steps would deliver justice to students who cleared the National Eligibility-cum-Entrance Test (NEET).

Praises Pradhan’s work as Education Minister

Recalling Dharmendra Pradhan’s tenure, Shah highlighted several initiatives undertaken during his time in the Education Ministry. He credited Pradhan with helping implement the National Education Policy (NEP), expanding PM SHRI schools, promoting digital education, strengthening skill development and improving coordination between industry and academic institutions.

Shah also said Pradhan worked towards making examinations more inclusive and student-centric, adding that his tenure reflected his commitment to the vision of a developed India.

Resignation follows NEET controversy

Dharmendra Pradhan’s resignation comes amid nationwide protests over alleged irregularities in the NEET examination and growing demands for accountability.

The resignation has triggered political reactions across party lines. While opposition parties have described the development as a result of sustained student protests, BJP leaders have projected it as an example of accountability and commitment to national interest.
