Solar Dehydration Technology: A Sustainable Innovation by IIT Kanpur Introduction IIT Kanpur has developed an innovative Solar Dehydration Technology , which is designed to help farmers preserve agricultural produce using renewable solar energy . This eco-friendly method significantly reduces post-harvest losses and enhances shelf life , making it a cost-effective and sustainable solution for the agricultural sector. What is Solar Dehydration Technology? Solar dehydration is a process where sunlight is used to remove moisture from food products like fruits, vegetables, and grains . By lowering moisture content, the technology prevents spoilage and microbial growth , ensuring better quality and long-term storage . Unlike conventional drying methods, which rely on electricity or fuel-based systems , this method reduces dependency on fossil fuels and promotes green energy solutions . How Does Solar Dehydration Work? Collection of Solar Energy Sunlight is captured using solar panels ...

Lumpy Skin Disease (LSD) – A Detailed Overview 1. About Lumpy Skin Disease (LSD) Lumpy Skin Disease (LSD) is a contagious viral disease that affects cattle and buffaloes . It is caused by the Lumpy Skin Disease Virus (LSDV) , belonging to the Capripoxvirus genus in the Poxviridae family . The disease leads to severe economic losses in the livestock industry due to decreased milk production, weight loss, and trade restrictions. 2. Causes & Transmission Pathogen : Lumpy Skin Disease Virus (LSDV). Mode of Transmission : Vector-borne transmission : Spread by blood-feeding insects , such as: Flies (Stomoxys species) Mosquitoes (Aedes and Culex species) Ticks (Rhipicephalus and Amblyomma species) Direct Contact : Through infected animals. Contaminated feed, water, or equipment . Aerosol transmission (rare but possible in crowded conditions). 3. Symptoms of Lumpy Skin Disease Fever (40–41.5°C). Large firm nodules (2-5 cm in diameter) on the skin, covering the head, neck, limbs, u...

Nano Urea – A Breakthrough or a Concern for Crop Yields? Introduction Nano Urea, developed by the Indian Farmers Fertiliser Cooperative (IFFCO) , is a nanotechnology-based fertilizer that aims to enhance nitrogen uptake in plants. However, recent studies suggest that its continued use may reduce rice and wheat yields , raising concerns over its long-term sustainability. About Nano Urea Development : Created by IFFCO , a leading fertilizer cooperative in India. Aimed at providing an efficient and eco-friendly nitrogen source for crops. Composition & Properties : Contains 4% nitrogen in nano form. Particle Size : 20-50 nm , which enhances absorption and efficiency . Higher surface area and number of particles per unit area than conventional urea. Potential Benefits of Nano Urea Higher Nutrient Use Efficiency (NUE) Improves nitrogen absorption, reducing excess fertilizer use. Environmental Benefits Reduces nitrogen loss through leaching and gaseous emissions . Minimizes groundwate...
