Publikováno v: Precision Agriculture. 13:219-235

Site-specific delivery of fertilizer is a useful tool to address differences in crop need. Modern systems with wirelessly networked sensors and valves allow multiple hydrozones to be created more easily than traditional wired systems. This allows irr

Publikováno v: California Agriculture, Vol 46, Iss 6, Pp 22-25 (1992)

Three devices that physically treat irrigation water were tested in the laboratory and the field. Results of these experiments indicate these water conditioners were ineffective in increasing the infiltration rate of water into the soil or in prevent
