Plant availability of nutrients recovered as solids from human urine tested in climate chamber on Triticum aestivum L.
چکیده انگلیسی

Recovered nutrients by freezing–thawing from human urine in combination with struvite precipitation and nitrogen adsorption on zeolite and activated carbon have been tested in pot trials with wheat, Triticum aestivum L., in a climate chamber during 21 days. A simple test design using sand as substrate was chosen to give a first, general evaluation of the nutrient (P and N) availability from these sources. Dry weight, plant growth morphology, total-P and total-N were analysed. The tests show a slow-release of nutrients (P and N) from struvite and from N-adsorbents. The nitrogen in all treatments was in the deficiency range for optimum yield for wheat. Higher pH than usual for soil tests contributed to the difficulties in plant uptake, especially in the pots with only struvite (with highest MgO addition) as nutrient source.
