nourishment contained in locally produced livestock excreta, thereby accurately determining the quantity of liquefied fertilizer to be sprayed to a target farm by automatically calculating the amount of applied fertilizer in NPK (nitrogen, phosphorous, potassium) when the excreta is returned to the farm...
The system to quantitatively manage NPK nourishment for ICT-based smart farms includes: a terminal inputting livestock information based on the web and requesting the calculation of an excreta amount and contained nourishment or inputting crop type information and requesting the recommendation of a ...
