A method for producing granular fertilizers based on pine sawdust containing ammonium nitrate is proposed. Physico-chemical properties of sawdust and fertilizers containing 20.0 wt.% nitrogen were studied. The effect of pretreatment of pine sawdust with 1 % wt. with a water solution of NaOH on the properties of granular fertilizers was explored. The results of a field trial on the cultivation of wheat varieties «Krasnoyarskaya 12» revealed the growth-stimulating effect of nitrogen-containing granular fertilizers in comparison with an unfertilized background. A more effective influenceon wheat yield of granular fertilizer fabricated from pine sawdust after their treatment with 1 % wt. with a water solution of NaOHThe achieved effect on 1,9 c/ha higher in comparison with thefertilizer based on original sawdust

Experimental Values

Surface tension of two binary systems ammonium nitrate-water and urea-water and of the ternary system ammonium nitrate-urea-water was measured as a function of concentration at 20 and 40 °C. The experimental values were compared with those calculated from the relations which were proposed for calculating surface tensions of ternary systems from measured surface tensions of both binary systems.

In this study, we investigated various physico-chemical properties of wheat and evaluated their correlation with cookie attributes. Results showed that damaged starch in wheat varieties ranged from 6.28 to 10.97%. SDS-sed. and AWRC values were recorded as 18.20-30.50 mL and 43.91-66.85%, respectively. WSRC, SOCSRC, SUCSRC and LASRC values varied over a wide range as 50.83-69.64%, 56.66-82.03%, 75.79-106.97% and 79.43-121.20%, respectively. Physical analyses of cookies made with wheat varieties indicated 25.20-26.60 cm width, 5.80-6.40 cm thickness and 39.38-45.86 spread factor and 2.17-3.91 kg hardness. Important correlations were reported between water absorption and SDS sedimentation (r= 0.912*). Likewise, a positive relationship was found between damaged starch and SUCSRC (r=  0.985**).Spread factor was found to be negatively correlated to ash (r= -0.977**), protein(r= -0.892*), SOCSRC (r= -0.952*), WSRC (r= -0.892*) and hardness (r= -0.990**).Correlation studies indicated that physico-chemical characteristics of flour are imperative in the evaluation of cookie making quality.

A program of investigations is outlined and the results of the first three years' work reported. Eight wheat varieties, differing widely in resistance to stem rust, showed no corresponding differences in the physico-chemical properties of their expressed tissue-fluids. The infection of susceptible varieties was in some cases reduced by administering extracts of resistant varieties in petri-dish cultures or by direct injection into inoculated leaves. The injection of the juice of infected leaves into healthy leaves failed to demonstrate the presence of any toxin excreted by the fungus. The injection of salicylic acid, catechol or vanillin in suitable concentrations frequently caused a reduction in infection. These phenolic compounds in very low concentrations stimulated the growth of Helminthosporium sativum, but at higher concentrations inhibited it. The same phenols inhibited the germination of rust spores. On filtered wheat-juice rust spores also failed to germinate, though on unfiltered juice they germinated normally.

Density of the ternary system urea-ammonium nitrate-water was measured in the range of overall concentrations 0-75 mass % at temperatures of 0, 20, 30 and 40 °C. The experimental data are compared with the values calculated from the relation obtained by combining the temperature dependences of densities of the binary systems urea-water and ammonium nitrate-water.

For the granulation of nitrate-sulfate-carbonate melt, the prilling method is applied using a granulation tower. The composition and properties of new types of fertilizers were studied. It is shown that with the ratio NH4NO3: СаСО3: (NH4)2SO4 = 100: 24: 1 the product contains 28,03% - N, 0,50% - SO3, 10% - СаО and has a granule strength of 6.03 MPa, which is much higher than the strength of pure NH4NO3 granules (1.32 MPa). The absorption of pure AN granules is 4.82 g. With an increase in the proportion of chalk and ammonium sulfate to the NH4NO3: СаСО3: (NH4)2SO4 = 100: 24: 1 ratio, the absorbency of the LAN granules is 2.57g.
