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.

Abhishek Banerjee says will not bow to BJP after nearly 11 hours of ED questioning

After spending nearly 11 hours before the Enforcement Directorate, TMC leader Abhishek Banerjee said he would not bow to the BJP and accused the ruling party of using investigative agencies for political purposes.

Abhishek Banerjee

Trinamool Congress leader and Diamond Harbour MP Abhishek Banerjee on Tuesday said he would not bow to the BJP after spending nearly 11 hours being questioned by the Enforcement Directorate (ED) in connection with an ongoing investigation.

Speaking after the questioning, Banerjee alleged that central agencies were being used to target opposition leaders and asserted that he would continue his political fight despite what he described as sustained pressure.

The TMC leader has repeatedly maintained that investigations involving him are politically motivated, a charge he has made on several previous occasions while appearing before central agencies.

His appearance before the ED comes amid a period of heightened political activity and multiple investigations involving leaders in West Bengal. Recent days have also seen Banerjee face summons and questioning in separate matters by state investigative agencies.

After leaving the ED office, Banerjee reiterated that he would not be intimidated and said he remained committed to his political responsibilities. He also accused the BJP of attempting to weaken opposition parties through investigative action, an allegation that the BJP has rejected in the past.

The Enforcement Directorate has not publicly commented on Banerjee’s remarks. The investigation related to the questioning remains ongoing.

DMK attacks Rahul Gandhi, accuses him of weakening opposition unity

DMK has intensified its criticism of Rahul Gandhi, alleging that the Congress leader’s actions have weakened opposition unity and strained relations within the INDIA bloc.

Rahul-Gandhi

The war of words between the DMK and Congress has intensified, with the DMK launching a strong attack on Leader of Opposition Rahul Gandhi and accusing him of contributing to divisions within the opposition alliance. The criticism comes amid strained ties between the two parties following their political split in Tamil Nadu.

According to the DMK, Rahul Gandhi’s political approach has weakened unity among opposition parties. The party’s IT wing mocked the Congress leader on social media, while an editorial published in the DMK’s official mouthpiece Murasoli questioned his recent remarks on opposition solidarity.

DMK questions Rahul Gandhi’s remarks on opposition unity

In its editorial, Murasoli argued that Rahul Gandhi was speaking about opposition unity despite, according to the DMK, contributing to disagreements among alliance partners in several states. The publication cited criticism directed at Congress by various opposition parties and suggested that the party’s actions had often created tensions within the INDIA bloc.

The editorial also referred to past political disputes involving Congress and Left parties, particularly in Kerala, claiming such episodes had raised concerns among opposition allies about Congress’s approach toward its partners.

Tamil Nadu political fallout adds to tensions

The attack comes after a major political realignment in Tamil Nadu. Following the 2026 Assembly elections, Congress ended its alliance with the DMK and joined the government led by Vijay’s Tamilaga Vettri Kazhagam (TVK). The move left the DMK in the opposition and significantly altered the political equation between the two former allies.

The DMK has alleged that Congress benefited from the alliance during the election and later abandoned its partner. The party’s editorial questioned whether assurances from Congress leadership would be trusted by alliance partners after the developments in Tamil Nadu.

Congress rejects allegations

Congress has not issued a detailed official response to the editorial, but party sources have rejected the allegations. According to the party, its decisions in Tamil Nadu were made in line with the mandate delivered by voters and were not intended to undermine either the DMK or the broader opposition alliance.

The latest exchange highlights growing strains between two key opposition parties even as leaders continue to stress cooperation on national issues. Just days earlier, Rahul Gandhi had said that the DMK remained aligned with the opposition on defending the “idea of India” despite political differences.
