Using drip irrigation in conjunction with slow-release fertilizers is particularly effective in controlling nutrient loss to the environment. Also, drip irrigation virtually eliminates disease spread from splashing water. The ultimate form of reducing water loss to the environment is found in systems where runoff water is recycled and reused. Simply put, overfertilizing is polluting. Anything that can be done to reduce the amount of fertilizer protects the environment and saves money.
Nutrition is one of the most important aspects in producing healthy, marketable crops.
Optimize fertilizer use to produce healthy plants, but avoid excessive use with high losses. Optimizing fertility means providing nutrients in the right quantities at the right times. Providing the right balance and amount of nutrients requires some thought. Remember to account for nitrogen and phosphorus in irrigation water. To minimize these problems, apply only enough fertilizer to meet plant needs, watering separately as necessary.
