Boron is also an important calcium synergist, governing the transport of calcium around the plant, which is critical for preventing crop quality disorders. Boron deficiencies are widespread particularly in light, sandy soils. Typical deficiency symptoms include low flowering rate, restricted pollination, leaf distortion, fruit deformity and increased disease susceptibility. Now you can address your boron requirements with an ACO Registered Farm Input. Boron Essentials™ contains 3% boron organically chelated with fulvic acid and amino acids. This revolutionary mix of biological chelating agents improves plant uptake and assimilation of boron.
