Broad range from which to regulate:
-Climate (El-Hendawy et al.)
-Soil Quality
-Rainfall
-Crops (El-Hendawy et al., Smith)
How do we regulate with so many aspects?
There are no real regulations for water in organic farming:
Farmers can use as much water as they need. Not enough water is being replenished (Little)
Below is a list of regulations based on regional climate, local water resources and topography. Rules layed out for water application are considered standard practice for all businesses applying for organic certification. Other regulations on water consumption and water source are enforced where applicable.
Listed below is also recommended water managemnt methods that are not enforced for organic certification.
Any method is acceptable when it comes to application. However, farmers much make sure that they are trying their utmost to conserve water.
As specified in the Water Consumption section, there is a certain water amount that farmers will be allowed to use based on the crops, rainfall, and climate. Keep in mind that some methods for irrigation are not as efficient as others.
Therefore, while in the process of attaining the organic certification, the USDA suggests, but does not demand, the use of drip method irrigation.
There is some debate as to whether there are benefits of drip irrigation. The USDA finds that there are benefits to its use when it comes to water conservation (Pro: Asif et al., Maisiri et al., Against: Al-Jamal et al.)
Farmers will have to keep track of the amount of rain fall and the rate at which they are watering their crops. The certification will be issued based on how these results hold up with the New Organic Standards for Irrigation.
The water that your business uses to produce its product can not be more than is being naturally replenished.
Listed below are the regulations beased on your buisnesses source for irrigation water:
If your region is rated by the National Weather Service to have high annual percipitation, your business should be equipt to retain and distribute this resource to your product.
Water Sources that are not considered organic are:
The goal, when it comes to consuming water, is to use it as efficiently as possible. Set in place are methods for measuring the optimum amount of water. While we want to conserve water, there is also a need to have a large yield so farmers can financially succeed.
Farmers will be required to maintain a record of the amount of rainfall that occurs annually, what time of the year or season it happens, and the rate at which water is being used to irrigate (volume/hour). (This only applies to non-greenhouse agriculture)
From there, the Organic Certification Agent will calculate how much water the farmer needs to produce a healthy yield based on crop and climate averages of the region for growth.
The certification will be issued based on the results of these calculations.
The amount that the farmer can go over will be based on the size of the farm and climate the farmer is growing in.
To be considered for organic certification your businesses form of irrigation water must be tested for:
