摘要： Prescribing a drip line for use in a field includes: accessing soil conditions data that includes vertical transect data relating to at least one vertical transect of soil in a field; based on a plant type and a length of time between a first watering and a second watering of a plant via the drip line, determining, a desired plant available water content of a portion of the soil within the at least one vertical transect to be substantially achieved as a result of the first watering; and based on the vertical transect data, the determined desired plant available water content, climate conditions data and geographical conditions data, determining perforation spacing and flow rate for a set of emitters for the drip line such that the desired plant available water is substantially achieved in the portion of the soil.
