Satellite imagery shows how the Earth’s surface looks from above. It depicts the Earth’s surface at various spectral, temporal, radiometric, and increasingly detailed spatial resolutions, as is determined by each collection system’s sensing device and the orbital path of its reconnaissance platform. Satellites and the images they provide differ because they are used for...
Agriculture advisory services, also known as extension services, refer to the entire collection of organizations that help individuals involved in agricultural production solve problems and gain information, skills, and technologies to enhance their livelihoods. It’s an integral part of the ecosystem of the market and nonmarket businesses and agents that deliver vital information to...
Major challenges in the agriculture in India Plant health may not be in the news as much as climate change and other environmental issues going on in the world right now, but it can have a much more significant impact on people’s lives than most people realize. Humans have fought plant diseases and pests...
Soil is a conglomeration of solids, liquid and air components. The solids consist of organic matter, minerals and micro-organisms. Liquid mainly comprise the water held between the solids and air comprises gaseous components released by various microbial processes, recycling of nutrients and exchange of gases with atmosphere occurring in the soil medium. Soil forms...
Soil moisture is defined as the water held in the pores of soil and this forms the water reserve available to quench the crop’s water requirement. Rainfall being the primary source of water, fills up the soil reserve which can extend from half meter to one meter in depth from surface or even deeper...
Earth’s climate has changed throughout the history. The climate is changing drastically now than at any point in history, mainly because of the anthropogenic activities.
