Using Micro-Sprinklers in Strawberry Production Saves Water
What Has ANR Done?A study was conducted at Manzanita Berry Farms in Santa Maria during the 2014–2015 production season to evaluate the potential of micro-sprinklers in strawberry production. The study compared conventional aluminum sprinklers with micro-sprinklers on about one hundred and twenty 330-foot-long strawberry beds. Data were collected on the amount of water distributed, electrical conductivity of soil that determines salt condition, strawberry yield, and the incidence and severity of powdery mildew and botrytis fruit rot. While there were no conclusive findings about diseases, there were significant water savings without a negative impact on fruit yield. Detailed information about the study design and findings can be found at:
Significant water savings without additional maintenance costsThis study demonstrated 32% water savings in just 3 weeks of using the micro-sprinkler system. This new information can inform future growing practices for this important California crop, valued at $2.2 billion. An initial estimate by a vendor suggests that equipment and handling costs of the micro-sprinklers are more or less similar to those of the aluminum sprinklers. If adopted, strawberry growers could conserve resources without incurring additional maintenance costs or experiencing any changes to strawberry yield.
