The elemental composition of keratohyalin granules from the interpapillary and papillary lingual epithelium and the oesophageal epithelium of the rat were studied by X-ray microanalysis in an EMMA-4 analytical electron microscope, equipped with an energy dispersive detector. A quantitative assay of the sulphur concentration in keratohyalin granules was performed, using a suitable sulphur standa...

; Studies on the distribution of different fOrulS of sulphur in seven widely occurring soil series representing five great groups viz. Udorthents, Fluvaquents, Dystrochrepts, Hapludalfs and Hapludolls indicated that non sulphate-sulphur, mostly contributed to the total sulphur (86.7%) followed by organic-sulphur (10.0%) and sulphate-sulphur (3.3%). All forms of sulphur had significant positive ...

A field experiment was conducted to assess the effect of farmyard (cattle) manure (FYM) and inorganic nitrogen (N) phosphorus (P) fertilizers on growth and tuber yield of potato (Solanum tuberosum L.). The treatments consisted of factorial combination of 4 levels of FYM (0. 10, 20 and 30 t h-1) and three levels of inorganic NP fertilizers (0, 33.3%, 66.6% recommended rates) laid out in a Random...

This Bulletin discusses several manufacturing processes for organic compound fertilizers overseas and in Taiwan. The different formulations of N-P2O5-K2O in the fertilizers are also reported. The yield response of different crops from the application of organic compound fertilizer reflects their superiority over organic fertilizers. Experiments also showed that the use of organic compound ferti...

ome organic fertilizers are suitable for greenhouse crops and can also fit the current ways of applying fertilizers commercially. However, not much information is available on plant response, nutrient supplying power, or the environmental impact of nutrient leaching with organic fertilizers. Not surprisingly, because of their differences in the makeup, levels of success in growing acceptable gr...

Sulphur (S) is ranked as 4th most essential nutrient after nitrogen, phosphorous and potassium which plays a vital role in crop production. Its uses have declined recent years. S-deficiency soils of Odisha has increased from 36% during 2008–09 to 44% 2018–19. A field experiment was conducted at farmers’ Ankurda village, Goindia block Dhenkanal district, for two years (2018–19 2019–20) order stu...

Four-week-old seedlings of Grindelia camporum Greene were planted in a mild calcareous alluvial soil collected from Mahibullapur, in Lucknow district (26 300 N latitude–80 300 E longitude) in pot culture. The soil, rated sulphur deficient on the basis of available soil sulphur, was fertilized with calcium sulphate to provide sulphur at the rate of 10, 25, 50, and 100 mg kg 1 soil. Observations ...

Analytical procedures for the determination of selected speciation forms of sulphur have been proposed. The method for conversion of sulphur sols into homogeneous solutions sols allowing simultaneous determination of sulphur either in model solutions or in sols environmental samples has been described. The methods for determination of sulphur sols, elemental sulphur, soluble and insoluble sulph...
