The potential for amino acid forms of nitrogen to replace large amounts of conventional mineral nitrogen . Why plants fail to absorb or metabolize calcium efficiently when soil boron levels are low . Recommendations for conducting sap analysis every 7 to 10 days to identify nutrient needs . Optimal spray timing and the "point of deliquescence" to keep droplets liquid on leaves longer . The necessity of using clean water free of carbonates, such as rainwater or reverse osmosis water, for effective foliar sprays
