What are the pros and cons of irrigation in agriculture?
Drip irrigation
Pros Cons Saves water by minimizing evaporation Method cannot be used with high iron content water because emitters become clogged Nutrient losses from leaching is reduced Maintenance is required to keep system going No land grading required Chewing on tubing from insects and rodents can cause water leaks
