  • An experiment on strawberry (Fragaria Grandflora EHRH) was conducted in order to compare the effect of two compound fertilizers made for this crop, by Kyonggi Chemical Crop. LTD. with that of muriate of potash, sulfate of potash and ammonium nitrate in a farmer's vinylhouse during the winter period of 1984 to 1985. Results obtained are as follows; 1. The effect of compound fertilizers on the growth, number of inflorescences and yield of strawberry showed no significant difference from the effect of muriate of potash, sulfate of potash and ammonium nitrate. But the former increased the content of reduced, and total sugars soluble in diluted acid in the juice of strawberry. 2. As a whole, sulfate of potash increased sugar content in strawberry juice more than muriate of potash, which became the reason to increase the sugar content in the strawberry juice harvested from the compound fertilizer plots.

  • These studies were carried out to investigate the effects of potassium salts on the changes of chemical properties in submerged soil. Rice plants were cultured in submerged soil using potassium salts. Obtained results were as follows. In the submerged soil cultured with rice plants the value of pH was higher in the potassium chloride plot than in the potassium sulfate plot. The leaching of cations such as calcium, magnesium, potassium and ammonium were higher in the potassium chloride plot than in the potassium sulfate plot. On the other hand, the leaching of phosphate ion was slightly higher in the potassium sulfate plot than in the potassium chloride plot. The leaching of iron was higher in the planted plot than in the non-planted plot, but that of silica was higher in the non-planted plot than in the planted plot. However, the leaching of iron and silica was not affected by potassium salts.

  • The effects of a simultaneous application of KCl and lime on the root uptake of $^{54}Mn,\;^{60}Co,\;^{85}Sr\;and\;^{137}Cs$ by rice, soybean, Chinese cabbage and radish were investigated through 2 years' greenhouse experiments. At their early growth stages, a mixed solution of the radionuclides was applied to the water or soil surfaces of the culture boxes filled with an acidic loamy-sandy soil for the upper 20cm and $83g/m^2$ of fertilizer KCl and $200g/m^2$ of slake lime were applied to the surfaces. Distribution of radioactivities among plant parts and change in uptake pattern with plant species were not, on the whole, significantly affected by the application. It reduced effectively soil-to-plant transfer factors of $^{85}Sr\;and\;^{137}Cs$ for rice, of all for Chinese cabbage and of $^{54}Mn,\;^{60}Co,\;and\;^{137}Cs$ for radish without their growth inhibition. In rice, $^{85}Sr$ showed the highest decrease $({\sim}60%)$ while, in Chinese cabbage and radish, $^{54}Mn$ did $({\sim}80%)$. The exprimental results can become valuable reference data to establish countermeasures against a radioactive contamination of farm-land during plant growth.

  • This experiment was conducted to compare the frech and dry matter yields and feed values of Sorghum$\times$Sudangrsss Hybrid in accordance with different nitrogen and potassium fertilizer sources at the Dae-Ho reclaimed tidal land, Korea from 2003 to 2004. Soil salt contents of ammonium sulfate plots(T3, T4, T5) were higher than that of the urea plot(T2), but that of potassium sulfate plot(T6) was the lowest. The fresh yields of ammonium sulfate plots(T3, T4, T5) and potassium sulfate plot(T6) were higher than that of the urea plot(T2) as $173\%,\;173\%,\;144\%\;and\;90\%$. respectively. The dry matter and total digestible nutrient(TBN) yields were similar tendency like the results of the fresh matter yields. The crude protein(CP), neutral detergent fiber(NDF) and acid detergent fiber(ADF) contents of ammonium sulfate plots(T3, T4, T5) were higher than those of urea plot(T2), but those of potassium sulfate plot(T6) were the lowest. On the other hand, TDN content in potassium sulfate plot(T6) was the highest. It was desirable to use ammonium sulfate$(20\~30kg\;N/10a)$ and potassium sulfate fertilizer$(15kg\;K_2O/10a)$ than those of urea and potassium chloride fertilizer on reclaimed tidal land in view of forage production and its feed value.

  • The application of potassium above the optimum level may cause the inhibition of plant growth, fertilizer loss, and environmental pollution. Therefore, application rate of K fertilizer should be recommended on the basis of soil test. In order to determine critical K content in soils causing growth inhibition of vegetables, $1m^2-pot$ experiments with Chinese cabbage and radish were accomplished with various K-application rates. The threshold concentrations of exchangeable potassium causing the inhibition of plant growth were $0.96cmol_c\;kg^{-1}$ for Chinese cabbage in spring, and $1.28cmol_c\;kg^{-1}$ for radish in autumn. Above those concentration levels, the yields of them were decreased with the increase of potassium levels in soils. Germination rate of Chinese cabbage in spring decreased with increase of the electrical conductivity (EC) of soils due to application of potassium fertilizer. In the harvesting stage, the potassium contents of plant were increased with the increase of K application rate while plant uptake of nutrients was decreased at the K adjustment level of over $2.0cmol_c\;kg^{-1}$.

  • To examine the possibility of enhancing activity of foliar applied herbicides by spray methods and additives, field experiments were conducted to evaluate the effects of surfactant, spray volume, and additions of ammonium sulfate or potassium chloride to glyphosate on toxicity to Digitaria sanguinalis or Artemisia princeps. Glyphosate toxicity increased as spray volume was decreased from 120 1/10a to 40 and 80 1/10a. Additions of surfactant in the spray solution increased toxicity of glyphosate to D. sanguinalis and usually more pronounced effect was obtained at glyphosate 30.5g a.i./10a. Additions of 1 and 5% (w/v) ammonium sulfate to glyphosate increased toxicity to A. princeps at glyphosate 30.5 and 61.5g a.i./10a. 10% ammonium slufate, however, had no effect or were antagonistic. Additions of potassium chloride at 1,2 and 3% (w/v) were also very effective to increase herbicidal activity to A. princeps at glyphosate at 30.5 and 61.0g a.i/10a. These results suggest that the practices for enhancement of herbicidal activity by improvement of spray method and additions of ammonium sulfate or potassium chloride to glyphosate can be employed to use lower herbicide levels while giving the same degree of weed control in orchards and non-crop lands.

  • The effect of wallastonite, potassium chloride and potassium sulphate on the ammonification and nitrification of urea was studied in a non-planted green house experiment, filling with 500g soil in plastic pot and incubating for 17 days. Potassium sulphate gave superior effect on the neutralizing soil acidity of wallastonite than potassium chloride and raised soil pH which promoted ammonification and subsequent nitrification of urea. Less than 20% $NO_3-N$ against the sum of $NH_4-N$ and $NO_3-N$ was accumulated in soils incubated bellow pH 6.0. It seemed that pH 5.2 to 6.0 was the critical range for the nitrification of ammonium, or raising the concentration of ammonia in soils to the toxic level to the nitrification. It appeared that the nitrification could be occuring in low moisture, air dried, conditions of soil.

  • Underground migration of $^{54}Mn,\;^{60}Co,\;^{85}Sr\;and\;^{137}Cs$ in paddy and upland conditions was studied through two years' greenhouse experiment. At early and late growth stages of rice, soybean, Chinese cabbage and radish, a mixed solution of the radionuclides was applied to the water or soil surfaces of the culture boxes filled with an acidic loamy-sandy soil for the upper 20cm. Soil was sampled in layers upto $15{\sim}20cm$ down after harvest. Soil concentrations of the radionuclides decreased exponentially with increasing soil depth and more than 80% of the radioactivities remained in top $3{\sim}4cm$. The mobility of the radionuclides decreased in the order of $^{85}Sr>^{54}Mn>^{60}Co{\geq}^{137}Cs$. Downward migrations of the radionuclides were the greatest in rice soil and the lowest in soybean soil which was fertilized with the least amount of N, P and K. Differences in depth profiles between two application times indicate that the amount of daily migration from $0{\sim}1cm$ layer to the lower area decreases with increasing time after deposition. By a simultaneous addition of KCl and lime following the earlier application, downward migration in soybean, Chinese cabbage and radish soils changed little or retarded more or less but that in rice soil accelerated a little.

  • Effort of reducing wastes and their recycling is increasing in worldwide. Especially, extreme care for alkali recycling is required because of its environmental pollution and its corrosive characteristics. In order to manage alkali wastes effectively, it is necessary to make quality standards for recycling products from the alkali wastes because there are no quality specifications yet. In this study, we selected several recycling candidates from the alkali wastes based on the analysis of the most recent data of the various industrial sites. As a result, the recycling candidates from the alkali wastes are sodium hydroxide, aluminum sulfate, poly aluminum chloride. It is believed that the proper management system for waste products is required in governmental point of view and it propagates positively for resolving various environmental issues.

  • Leaching of $^{54}Mn$, $^{60}Co$, $^{85}Sr$ and $^{137}Cs$ in paddy soil was studied using lysimeter cultures in a greenhouse. The radionuclides were applied to the water surfaces shortly before transplanting and five different times between transplanting and harvest. Fertilizer KCl and slaked lime were added simultaneously in the rate of 83kg and 200kg, respectively, per l0a following the first application after transplanting. Percolating water was sampled until two days before harvest. Concentrations of the radionuclides in percolating water decreased in the order of $^{85}Sr$ > $^{54}Mn$ > $^{60}Co$ > $^{137}Cs$ on the whole. Time taken to reach the maximum was the shortest for $^{137}Cs$(< one week) and the longest for $^{54}Mn$ and $^{85}Sr$. Six days' water dropping started 47 days after transplanting reduced the concentrations of $^{54}Mn$, $^{60}Co$, $^{85}Sr$ and $^{137}Cs$ by factors of 30-180, 3-75, 2-4 and 3-6, respectively, depending on the application time. After the significant decrease, $^{54}Mn$ concentration tended to gradually increase but $^{137}Cs$ did to the contrary Percent leaching varied 0.09-6.2% for $^{54}Mn$, 0.009-0.9% for $^{60}Co$, 1.4-14.4% for $^{85}Sr$ and 0.002-0.06% for $^{137}Cs$, with the application time. The highest leaching came from the application at 40 days after transplanting for all the radionuclides. The addition of KCl and lime increased percent leaching of the radionuclides by factors of 9, 85, 4 and 9, respectively.
