Diagnosis foliar en la caña de azúcar. X. Efecto de la lluvia en los contenidos foliares de macronutrientes en la primera y segunda cosechas
This paper deals with the effect of rainfall before the sampling date on the composition of the + 3 leaf of the sugar-cane plant. By analysing data found in the literature the increase in the percentage of macronutrients due to 200 mm of rain which fell 2 months before sampling was estimated. In the case of the cane/plant the following values were obtained: P = 0.016 to 0.034% (depending of the type of soill: K = 0.071%; Mg = 00194 to 0 0388%. For the first ratoon crop the increase in leaf content was estimated to be: N=0.17%; P = 0 02%; Mg =0 027%: S= 0.055%%.
