nterest in organic fertilizers is growing in the greenhouse industry, but experience and trials are not keeping up. There is little information available on how well the new types of fertilizers provide nutrition for plants compared to traditional water-soluble chemical fertilizers. The most widely available “organic” fertilizers for application like traditional water-soluble fertilizers are fi...

Sulphur status of some soils in Edo Central, Nigeria was evaluated in five different locations; Ekpoma, Irrua, Uromi, Ubiaja and Agbede. The area lies within the derived savanna-forest transitional zone. Surface soil samples (0 – 15 cm) collected from the five localities wasanalyzed for their physico-chemical properties, inorganic, organic and total sulphur contents. Results showed that inorgan...

Oilseed crops grown in different types of soil experience nutrient deficiency, especially sulphur, zinc and boron, which affect crop productivity. To tackle it, management practices must be streamlined to avoid improper fertilizations deterioration health. With this background, experimental trials were conducted study the effect boron application on growth, yield components hybrid sunflower at ...

Chemical and spectroscopic studies have shown that in agricultural soils most of the soil sulphur (>95%) is present as sulphate esters or as carbon-bonded sulphur (sulphonates or amino acid sulphur), rather than inorganic sulphate. Plant sulphur nutrition depends primarily on the uptake of inorganic sulphate. However, recent research has demonstrated that the sulphate ester and sulphonate-pools...

an efficient method was employed for the ash and pyrite sulphur removal from bitumen using column flotation process. the bitumen samples containing 9.6% sulphur (6.81% in the pyrite sulphur form) and 26.4% ash were successfully showed up to 75.20% of pyrite sulphur (e.g.; 51.66% of total sulphur) and 70.81% of ash removal. the box-behnken design (bbd) was employed to design the experiments, to ...
