    Description: The present investigation was intended to furnish information concerning:(1) The movement of water-soluble and exchangeable potassium in the soil profile after successive fertilizer applications.(2) The form of potassium—exchangeable, soluble, or non-exchangeable—into which added potassium fertilizer is converted in the soil.(3) The effect of doubling the fertilizer ration on the absorption of potassium by the soil; and the effect of doubling the ration of irrigation water on the absorption and accumulation of potassium in the soil.(4) The effect of frequent successive summer irrigation following fertilizer application on the distribution of the three forms of soil potassium.(5) The effect of fertilization followed by irrigation on soil pH. value.

    Notes: Summary 1. Pot- and field-experiments were carried out in both sandy and medium clay soils to determine the fertilizing value of Huleh peat, both alone and in combination with manure and/or KPN. 2. Tests to compare the value of light and heavy peat-treatments were carried out in both pot and field-experiments. 3. Tests to determine the relative effectiveness of peat from upper and lower layers (0.5, 1.0 and 3.0 m) and from various locations, were carried out in the pot-experiments. 4. Persistence of fertilizing-value of peat was compared with that of manure in the pot-experiments. 5. Pot-experiments with dehydrated peat were carried out to determine the best drying method from the standpoint of fertilizing-value. 6. Preliminary trials were made to determine the most effective method of combining peat and KPN. 7. Botanical and soil-survey data is briefly reviewed and a chemical analysis of the peat is presented.
