Sulfur/sodium bentonite prills containing 5–40% of sodium bentonite were evaluated in a field experiment to determine the effects of the bentonite contents on their ability to supply sulfur to pasture plants. Comparative rates of oxidation of the elemental sulfur in the fertilizers to sulfate were deduced from plant sulfate contents and phosphate-extractable sulfate in soil (0–75 mm depth) over a period of 15 months. In grass-dominant pastures plant sulfate appeared to be more sensitive than… Expand

ABSTRACT Nutrient deficiencies in calcareous soils are mostly related to high soil pH whereas sulfur supplement could facilitate nutrient element uptake by the crop plants. However, inefficientExpand
Influence of sulphur fertilizer placement, soil moisture and temperature on yield response of rape to sulphur-bentonite
Experiments were conducted in the glasshouse to determine the effect of placement of S-bentonite fertilizer either on the surface of the soil or to a 5-cm depth at the time of planting on yieldExpand
Effects of Sulphur Bentonite Mixture Fertilizer for the Growth of Young Radish (Raphanus sativus L.)
Field study was conducted to evaluate the agronomic effectiveness of sulphur-bentonite fertilizer. Soil pH was slightly lower tendency to the increase of sulphur-bentonite fertilization, but did notExpand
Availability of different forms of sulphur fertilisers to wheat and oilseed rape
A pot experiment was conducted to compare the availability and efficiency of three sulphur (S) fertilisers to wheat in the first year and oilseed rape in the second year, using six agriculturalExpand
The effects of different manufacturing techniques on the availability of sulfate to pasture from mixtures of elemental sulfur with either triple superphosphate or partially acidulated reactive phosphate rock
Six different preparations of elemental sulfur incorporated into triple superphosphate and a single mixture of elemental sulfur with partially acidulated reactive phosphate rock were evaluated forExpand
Effects of different sources and rates of sulphur on the growth and foliar nutrition of nitrogen-fertilized lodgepole pine
The effects of nitrogen (N) fertilizer, alone and in combination with different sources and rates of sulphur (S), on foliar nutrients and tree growth are reported over 3 and 6 years, respectively.Expand
Oxidation of Elemental Sulfur in Granular Fertilizers Depends on the Soil‐Exposed Surface Area
Elemental S (ES) is the most concentrated S source and does not leach readily in soils but only becomes available to plants after oxidation to SO₄–S. Commercial ES fertilizers are usually in granularExpand
Source, Application Method, and Cultivation Effects on Recovery of Elemental Sulfur as Sulfate‐S in Incubated Soils
Abstract Elemental sulfur (S) may have lower costs, but lack of its availability as plant‐available sulfate‐S (SO4‐S) at the time of crop uptake may render it ineffective as an S fertilizer. FourExpand
Factors affecting the oxidation of elemental sulfur in soils
TLDR
The use of elemental sulfur (S0) to alleviate widespread S deficiencies in agricultural soils is limited by the unpredictability of its oxidation to plant available sulfate, so it should be possible to devise S fertilizer strategies that exploit the slow release characteristics of S0 to meet crop demands efficiently in a variety of conditions.

Elemental sulfur fertilizers and their use on crops and pastures
This paper reviews the use of elemental sulfur (S°) as a fertiliser and its efficacy in different pastoral and cropping situations. The effect of S° particle size on rate of oxidation is critical toExpand

The effectiveness of several fertilizers in supplying sulfur to temperate pastures
TLDR
The most soluble source, sulfate of ammonia, was the most effective source of sulfur to the pasture on the heavy-textured soil, followed by the less soluble gypsum but this order was reversed on the light-texture soil, which may have lost sulfate by leaching. Expand
