The Role of Charcoal Particle Size in Adsorption and Desorption Capacity of Potassium in Calcareous Soil | Chapter 1 | Novel Perspectives of Geography, Environment and Earth Sciences Vol. 8

 This stage aims to determine effect of atom sizes of charcoal on desorbed of adsorbed potassium utilizing silt mud loam makeup soil collected from Abo- Graib research station/ Department of researches and studies/ Horticulture commission. Potassium is considered expected one of the main main nutrient for most farming and economical crops. In this experiment, ten ml of potassium chloride resolutions (0, 5, 10, 20, 60, 100 and 200 mg K L-1) was added to (soil, soil+ black 0.5mm and soil+ charcoal 1mm) situations. The adsorbed potassium was extracted utilizing 1M- NH4AOc- pH = 7 and the potassium content in leachates was determined.  The judgments demonstrated that, when linked with soil situation at various concentrations, black treatments have a more forceful potential to desorbate potassium.  The desorbed potassium was 395 mg K kg -1 soil for (soil + charcoal width- 1 mm) treatment at a aggregation of 5 mg K L -1 and 386.5 mg K kg -1 soil for (soil + charcoal width- 0.5 mm) treatment and rude amount of desorbed potassium 383 mg K kg -1 was in soil for soil treatment and this current was matched various concentrations of the added potassium. The curves of potassium desorbed accompanied that the amount of desorbed potassium increased accompanying the addition of black, particularly when the piece sizes increased.  The allotment of desorbed potassium was 4.30% in the treatment utilizing soil and charcoal accompanying a diameter of 1 mm (5 mg K L-1) and lowered to 2.19% in the treatment utilizing soil and charcoal accompanying a diameter of 0.5 mm and hostile percentage of desorbed potassium was 1.30% in (soil) situation. The study's findings presented that the amount of desorbed potassium correlated unfavorably with the length of the charcoal piece, which can have an impact on the effectiveness of soil fertilization accompanying potassium.
