Relationship between phosphorus concentration in soil solution and phosphorus in shoots of barley

Popis výsledku v původním jazyce

Phosphorus concentration in the soil solution of agricultural soils should be a consensus of the agronomic and environmental aspect. The simplified procedure of soil solution extraction was developed and standardized. Based on barley cultivation in a plant growth chamber the relationship between P concentration in simulated soil solution and the response of test plant was evaluated. Three approaches were used to derive an adequate P concentration in soil solution. Based on the diagnostics of P content in barley the following adequate P concentrations in soil solution were derived: 0.23?0.86 ppm P for colorimetry and 0.9?1.75 ppm P for ICP-AES. Using the concept of the boundary line of yield the critical P concentration in soil solutions was 0.8 ppm P for colorimetry and 1.3 ppm P for ICP-AES. The concept of the boundary line of P efficiency index enabled to define the lower limits of suitability from the agronomic aspect:0.15 ppm P in simulated soil solution for colorimetry and 0.7 ppm
