The response of the variety Abadia to added phosphorus and the intensity and the replenishment factors of soils from the Ebro valley
Year: 1983
Type: article
Abstract: The relations between the uptake of phosphorus by a plant and fertility factors are studied. The wheat variety Abadia was grown under greenhouse at different levels of monocalcium phosphate according to the physico-chemical properties of the Brown Earths, Xerorendzines and Brown Soils, the soils in which these relations are evaluated. \nThere is a positive response to added P, with and increase in dry matter production and phosphorus content in this variety of wheat. \nBoth the dry matter production and the phosphorus content are related to the intensity factor, the maximum production being attained at concentration of 0.70 and 0.80 ppm in Brown Earths, a value that increases to 1 ppm in Brown Soils. \nThe optimum content of 0.40% of P in this variety of wheat is obtained at values of from 1.2 to 1.6 ppm P in the soil solution. \nGiven the very variable range of nutrient concentration in the soil solution for these plant characteristics, the replenishment factor is studied, an it is seen how the supply of phosphorus to the Abadia variety in these soils is controlled by this factor on reaching values of from 3.5 to 4.
