The continuous increase in fertilizer prices directly impacts the overall cost of crop production. According to government reports, farmers in states like Bihar are frequently utilizing 30 to 50 percent more fertilizers than necessary. In some districts, the consumption of fertilizers has been found to be significantly higher than the average. This overuse not only escalates farmers' expenses but can also negatively affect soil health. To address this critical issue, the Indian Council of Agricultural Research (ICAR) has developed an innovative Fertilizer Calculator app. ## ICAR's App: A Modern Solution for Farmers The precise and correct application of fertilizers is crucial for ensuring both the quality and quantity of crop yields. Applying excessive amounts of fertilizer leads to increased costs for farmers and wasteful resource consumption, while insufficient application can detrimentally affect production. Recognizing these dilemmas, ICAR has introduced this Fertilizer Calculator app. The application guides farmers in using fertilizers scientifically, with the dual aim of enhancing their income and improving soil health. ## Expert Insights and the App's Utility Dr. Abhik Patra, Subject Matter Expert (Crop Production) at Krishi Vigyan Kendra, Begusarai, demonstrated to TrendKia that the primary step for the scientific use of fertilizers is soil testing. Based on a soil test report or a soil health card, farmers can ascertain the actual status of nutrients available in their land and accordingly determine the appropriate amount of fertilizer. Dr. Patra further clarified that even if a farmer has not conducted a soil test, the app can still prove highly useful. In such scenarios, the app can estimate approximately 80 percent of the correct amount, assisting farmers in balanced fertilizer application. This approach helps control unnecessary fertilizer use, leads to improved crop production, and simultaneously reduces cultivation costs. ## How the Fertilizer Calculator App Functions A demo shared with TrendKia elaborated on the app's operational mechanism. Farmers can easily download the Fertilizer Calculator app on their mobile phones. Upon opening the app, they first need to select the crop they are cultivating. If a farmer possesses information from a soil health card, it can be entered into the app. For those without a soil test report, the app provides suitable fertilizer recommendations based on general agricultural guidelines. ## Customizing Fertilizer Types and Quantities The app also offers farmers the option to select various types of fertilizers. For Nitrogen, choices like Urea or Ammonium Sulphate are available; for Phosphorus, DAP; and for Potash, different alternatives can be chosen. Furthermore, the app allows for the selection of other micronutrients, including Zinc. After filling in all necessary information, the app automatically calculates and indicates the required quantities of Urea, DAP, Potash, and Zinc per hectare. For instance, a farmer cultivating paddy will receive precise details from the app, significantly simplifying the purchase and correct application of fertilizers. ## Beyond Total Quantity: Guidance on Split Doses and Balanced Nutrition Dr. Patra explained that the app not only specifies the total quantity of fertilizer but also provides information on when and how much of each fertilizer should be applied, known as 'split doses'. For example, comprehensive details on the phased application of fertilizers for paddy crops are available within the app. Officials also shared a demo with TrendKia regarding this feature. Experts believe that utilizing this app will empower farmers to adopt balanced nutrient management. This will lead to a reduction in unnecessary fertilizer expenditure, improved soil fertility and health, and ultimately, an increase in crop production. In essence, this app can prove instrumental in reducing farmers' cultivation costs and significantly boosting their profitability. ## What this means for you - **For Farmers:** This app will directly help farmers reduce unnecessary expenditure on fertilizers, thereby cutting cultivation costs and boosting their profits. - **On Soil Health:** Balanced use of fertilizers will help maintain soil fertility and improve the long-term health of agricultural land. ## Questions & Answers ### 1. What is the main purpose of the ICAR Fertilizer Calculator app? The primary goal of this app is to help farmers use the correct and balanced amount of fertilizers for their crops, enabling them to reduce costs and increase yields. ### 2. How does the app determine fertilizer quantities for farmers? Farmers can select their crop in the app and enter soil health card information if available. If no report is available, the app suggests quantities based on general agricultural recommendations. ### 3. Does the app work even without a soil test? Yes, according to Dr. Abhik Patra of Krishi Vigyan Kendra, Begusarai, even if a farmer has not conducted a soil test, the app can still be useful by estimating about 80 percent of the correct quantity. ### 4. What benefits will farmers get from this app? Using this app will prevent unnecessary fertilizer use, reduce cultivation costs, improve crop production, and maintain soil fertility, thereby increasing farmers' profits. ### 5. Does the app offer options for different types of fertilizers? Yes, the app provides options to select Urea or Ammonium Sulphate for Nitrogen, DAP for Phosphorus, and Potash, along with other micronutrients. ### 6. Does the app only provide total quantity or also split dose information? The app not only provides the total quantity but also gives information on when and how much of each fertilizer should be applied, known as split doses, such as for paddy crops. --- _TrendKia — Har trend, sabse pehle..
