Get to know potassium nitrate in citrus nutrient management

It has been shown that KNO3 boosts yield by producing high quality fruits, increasing sizing, TSS and intense color. University of Florida research, potassium nitrate has been shown to results that a KNO3-based fertilizer program at a rate of 25 lbs/A/spray applied pre-bloom (mid-February), post-bloom (April) and at fruit fill (July/August) increased yield and size of fresh market 'Valencia' orange when compared to an untreated control. Both the KNObased program and control program received standard recommended soil fertilizer applications 3 to 4 times throughout the season.
