An Experiment carried out in Al-Yarmook Area in Baghdad for the growing season 2014 to study the effects of foliar application of Salicylic acid and Humic acid on Vincristine and NPK content in Catharanthus roseus. A factorial experiment was applied including two factors according to The Complete Randomized Block Design, the first factor included four levels of salicylic acid 0, 25, 50, and 100 mg.L-1 which were represented with S0, S1, S2, and S3 sequentially, the second factor included three levels of Humic acid 0, 0.75, and 1.5 ml.L-1 and were represented with O0, O1, and O2 sequentially to make up 12 factors in total that were distributed randomly upon three replicates and each experimental unit included 8 plants. The results were analyzed using Genestat and the differences were tested according to (LSD) with a level of probability 5% and the results were as follows: Vincristine levels increased in the leaves of Catharanthus roseus as a result of foliar application of Salicylic acid and Humic as well NPK levels in leaves. Vinblastine was not detected in all treatments. The interaction effect between 100 mg.L-1 Salicylic acid and 1.5 ml.L-1Humic acid had an exceeding effect for all the studied parameters. It may be concluded that Salicylic and Humic acid may be used to increase Vincristine alkaloid content in Periwinkle plants at the levels 100 ml.L-1 and 1.5 mg.L-1 subsequently.

The experimental results showed that humic acid at 10 ml.L-1 and calcium chloride at 150 mg.L-1 (Ca150H0) significantly gave the highest leaves number of 11.20 and 11.47 leaves, the highest leaf area of 195.21 and 210.25 cm2, the highest plant dry weight of 16.92 and 17.95gm, the highest leaf nitrogen content of 2.50 and 2.45 %, highest leaf phosphor content of 0.37 and 0.44% and the highest leaf calcium content of 3.17 and 3.45% for both seasons, respectively. The lowest value of these parameters was found in the control (Ca0H0) treatment. It could be concluded of this experiment that the humic acid at level H10 and calcium chloride at level Ca150 improved vegetative characteristics and leaf mineral content gerbera plant cv. Yanara

The beneficial effect on yield and quality of `Anna' apple fruits for the application of ascobine at 0.1% and citrine at 0.6% was studied during 1995 and 1996. Results showed that two citrine sprays at start of growth and 30 days later of ascobine at 0.1% or citrine at 0.6% were of material promotion effect on yield, fruit weight, total soluble solids, and total sugars, while reducing the total acidity. Both fertilizers were equally very effective in all the studied characters. The most striking and promising treatment was the application of ascobine at 0.1% or citrine at 0.6% twice during the growing season; i.e., growth start at 30 days later.

This study was conducted to investigate the effect of bacterial bio-fertilization A. chroococcum and P. putide and four levels of compost (0, 1, 2, 3) tons.h-1 on the leaves content of N.P.K elements. The experiment was carried out in one of the greenhouses of the College of Agriculture - University of Al-Qadisiyah during fall season 2018-2019. It designed in accordance with the Randomized Complete Block Design (RCBD) with three replicates in sandy loam soil. The means of treatments were compared with the least significant difference (LSD) at (5)% probability level. The results present that the treatments of A. chroococcum, P. putide and compost at (3) tons.kg-1 significantly increases the leaves content of K.P.K compared to all other treatments in the flowering stage (4.970, 0.5000, and 4.930) mg.kg-1, respectively. This treatment was followed by the effect of the treatment of A. chroococcum and compost at (3) tons.kg-1, which increases the values of all traits except the leaf content of (P). Bio-fertilizer with P. putide + A. chroococcum significantly increases the leaves' content of P.

Soil Humic Acid

The Hot Water Percolation (HWP) technique for preparing soil extracts has several advantages: it is easily carried out, fast, and several parameters can be measured from the same solution. The object of this study was to examine the possible use of HWP extracts for the characterization of soil organic matter. The HPLC-SEC chromatograms, UV-VIS and fluorescence properties of the HWP extracts were studied and the results were compared with those of the International Humic Substances Society (IHSS) Soil Humic Acid (HA), IHSS Soil Fulvic Acid (FA) and IHSS Suwannee Natural Organic Matter (NOM) standards as well as their HA counterparts isolated by traditional extraction methods from the original soil samples. The DOM of the HWP solution is probably a mixture of organic materials, which have some characteristics similar to the Soil FA fractions and NOM. The HWP extracted organic material can be studied and characterized using simple techniques, like UV-VIS and fluorescence spectroscopy.

Fouling Materials

Effects of clay on fouling due to organic substances and clay were evaluated by model fouling materials and kaolin. Model fouling materials selected were protein, polysaccharide, fulvic acid, humic acid and algogenic matter (EOM:ectracellular organic matter, microbial decomposition products) and kaolin was selected as the clay material. Polysulfone membrane (MWCO(Molecular Weight Cut-Off) 10,000, 50,000 and 200,000) was used as an ultrafiltration membrane. In particular, the flux measurement of solutions containing algogenic matter used an ultrafiltration membrane of MWCO 50,000. The flux of protein and polysaccharide with coexistence of kaolin increased in the case of the ratio of MW/MWCO being greater than one, but did not increase in the case of the MW/MWCO ratio being below one. In contrast, the flux of fulvic acid and humic acid with coextence of kaolin decreased regardless of the ratio of MW/MWCO. The addition of dispersion agent and coagulant in the organic substances and kaolin mixture solution changed the size distribution of kaolin, and resulted in a change of the flux. EOM and microbial decomposition products decreased with the increase of the fraction of organic matter having molecular weight more than MWCO of membrane. The flux of the algogenic organic matter with coexistence of kaolin decreased with the increase of the amount of kaolin. It was suggested that the decline of the flux with coexistence of kaolin was due to the change of the resistance of the kaolin cake layer corresponding to the change in kaolin size distribution with charge.
