Soil wetness plays a key role within the lifetime of the plant. Nutrients within the soil resolution offer the plant with the food it has to grow.Water is additionally essential for regulation plant temperature through the method of transpiration. Plant root systems square measure higher developed once growing in dampish soil.The amount of latest productive land which will be brought underneath production is restricted. In several nations, the necessity to feed a growing population is goading associate degree intensification of agriculture finding ways in which to grow higher yields of food, fuel, and fiber from a given quantity of land, water, and labor. This unit describes the physical and environmental factors that limit crop growth and discusses ways in which of minimizing agriculture's in depth environmental impacts. Soil wetness sensors live the meter water content in soil. measure soil wetness is vital for agricultural applications to assist farmers manage their irrigation systems additional with efficiency. the net of things (IoT) is that the inter-networking of physical devices (also named as "connected devices" and "smart devices"), buildings, and alternative things embedded with natural philosophy, software, sensors, actuators, and network property that change these objects to gather and exchange knowledge.
