Promotion of root elongation by phosphorus deficiency. Hajabbasi, M. A., et al., 1994. Phosphorus effects on root growth and development in two maize genotypes. The Rhizopon and Hortus USA research centers in the US and Holland welcome your questions about plant rooting. The suggestions for the use of Rhizopon AA and IBA Water Soluble Salts are based on the outcome of tests and experiments carried out by international testing stations, research centers, scientific publications and Rhizopon and Hortus USA's own research.
Testing is essential.
Suitable test rates should be used on a small portion of the crop before doing extensive treatment. Select the rate which provides the desired effect. The actual conditions at your facility may not be the same as the place were the data was obtained. You might find highly successful results if you vary the concentrations somewhat from the listed amount. All rights reserved.
