The two sulfur forms were elemental sulfur (S 0) and gypsum, both of which were applied at 0,and g S kg −1 soil, for a total of five treatments. The results showed that both S 0 and gypsum significantly increased rice biomass compared to the control (CK), and rice yield was increased – by: With legumes, limitation of S can reduce N 2 fixation by affecting nodule development and function.
The present report deals with the influence of S on yield formation and N 2 fixation of legumes and tries to explain the lower yield formation and reduced N 2 fixation of S-starved by: Slag-based gypsum (SBG) is a unique synthetic gypsum which is alkaline in nature, besides calcium (Ca) and sulphur (S); it contains appreciable amounts of iron (Fe), silicon (Si), phosphorus (P) and zinc (Zn).
In this study, we evaluated the efficacy of SBG as a source of S, Ca and Si for groundnut in comparison with natural gypsum (NG). The effect of different levels and time of Author: Laxmanarayanan M, Nagabovanalli B.
Prakash, Prabhudev Dhumgond, Shruthi, Shrenivas Ashrit. Sulfur as a plant food. Gypsum on a dry basis contains about 23% calcium and 17% sulfur. That means that if you apply one ton of gypsum you will apply about # of sulfur per acre.
That is enough to meet several years of crops demands. It also makes it one of the least expensive sulfur sources you will find in the market place today. The effectiveness of sulfidic materials (SM) and gypsum (G) application at the rates of 0, 40, 80,and kg S ha-1 on the growth, yield, and mineral nutrition of rice (Oryza sativa L.; BR.
mental sulfur supplied sufficient sulfur for 2 years while the same amount of sulfur as gypsum lasted one year. In a companion study on the same site Jones and Ruckman () found that gypsum and elemental sulfur with particle sizes less than 0.
I5 mm applied at 45 kg S/ha produced cumulative yield increases above unfertilized. Gypsum is calcium sulfate (CaSO 4).Refined gypsum in the anhydrite form (no water) is percent calcium (Ca) and percent sulfur (S). Usually, gypsum has water associated in the molecular structure (CaSO 4 2H2O) and is approximately percent Ca and percent S (plaster of paris).
Gypsum fertilizer usually has other impurities so grades are approximately 22 percent Ca and Once the gypsum dissociates into calcium and sulfur the calcium has the greatest attraction for the soil particle displacing sodium.
The calcium will help flocculate (aggregate) the soil whereas the sodium on the soil causes dispersion. This means that calcium from the gypsum will improve soil structure and improve plant growth. consists of the following stages: reduction of gypsum to calcium sulphide; stripping of the sulphide with CO.
gas and the production of sulphur. Thermal reduction study showed that gypsum can be reduced to CaS with activated carbon in a tube furnace operating at ºC. The CaS yield was 96%.
The CaS formed was slurried in water. Gypsum Fact Page 1 of 4 FERTFACTS GYPSUM INTRODUCTION Gypsum is the common name of hydrated calcium sulphate, which has the chemical formula CaSO H 2O. Gypsum is obtained in two ways, being either: • mined from naturally-occurring deposits, or • obtained as a co-product from the manufacture of phosphoric acid.
This. In a pot experiment (culture substrate: perlite with a granulometric composition mm) with peas (Pisum sati- vum L.) we studied the influence of sulphur supply on S and N concentrations, yield.
Sulfur was applied at the rate of 10 kg/ha to 35 S labelled soil. At maturity of the grain, straw, and roots were analyzed for total S and 35 S.

Sulfur application increased grain yield and all sources were equally effective under all three conditions (SNF, SF, DF), except gypsum, which was not different from the control under SF and DF. The low biomass yield of leucaena was mainly caused by the infertile soil, resulting from the combination of a low pH and a sandy composition.
The application of S ( kg/ha) as gypsum and the maximum application rate of P ( kg/ha) were suitable to. yield, protein, oil and methionine contests of both the crops increased significantly irrespective of the source of sulfur.
However, they reported gypsum as a good source of sulfur especially for oilseed crops growing on alkaline soils. Using different soil amendments Chand et al. () reported that. Effects of sulfur supply on the yield, composition and quality of grain from cereals, oilseeds, and legumes.

gypsum and sulfur inoculated with Acidithiobacillus, applied at different rates and mixed proportions, would alleviate soil salin-ity. The effect of PK rock biofertilizers in combination with these amendment treatments on biomass yield and nutrient uptake of cowpeas was also tested in this study.
Materials and methods Agricultural Gypsum (Calcium Sulfate – CaSo 4) Building more productive soil naturally. Agricultural gypsum works as a soil amendment, conditioner and fertilizer to improve the soil.
Is gypsum a cost-effective solution for your calcium and sulfur needs. Check soil tests and consult your agronomist. S, applied as gypsum and elemental S, on forage produc-tion, S uptake, and botanical composition of annual grass-land pasture at two locations in the humid north coastal region in California.
THE IMPORTANCE of sulfur as a fertilizer on Cali-fornia grasslands has been widely recognized. Not only. Gypsum As A Sulfur Fertilizer For many years, gypsum was used to supply sulfur to crops, when needed. The effect of use of sulfur in a fertilizer program for corn production on sandy soils has been positive.
An example of that response when the sulfur was applied in a band at planting is shown in Table 5. Table 5. “Gypsum is an excellent source of sulfur for plant nutrition and improving crop yield.” Meanwhile, calcium is essential for most nutrients to be absorbed by plants roots.
“Without adequate calcium, uptake mechanisms would fail,” Dick said. “Calcium helps stimulate root growth.” 2. Improves acid soils and treats aluminum toxicity.
Gypsum has 17% sulfate, which is the most absorbable form of sulfur for plants. Gypsum Helps Reclaim Sodic Soils. Gypsum is used in the reclamation of sodic soils.
Where the exchangeable sodium percentage (ESP) of sodic soils is too high, it must be decreased. Sulphur application through gypsum recorded the highest pod yield ( kg/ha) of groundnut that was and percent more than obtained under SSP and elemental sulphur treatment, respectively.

Application of sulphur at 75 kg S/ha was recorded highest shelling% (%) which were and per cent higher over 30 and 15 kg S/ha. A field experiment conducted on rapeseed (Brassica juncea L.) during – in a typical lateritic soil (Alfisol) of West Bengal, India revealed that sources of sulfur viz.
gypsum and magnesium sulfate and levels of sulfur (0, 20, 40, 60 kg S ha −1) have significant influence on grain yield, total biological yield, sulfur concentration in grain and stover, total sulfur uptake, oil. sulfur. Harvesting and leaching remove sulfur from the sulfur cycle.
Crop removal varies from less than 10 lb/a of sulfur for grain crops to more than 20 lb/a for legumes and corn silage (Table 1). Sulfate sulfur is not readily held by soil particles, except for acid clays, so in most soils it can be leached below the root zone. However. Gypsum is a see also of sulfur.
As nouns the difference between gypsum and sulfur is that gypsum is a mineral consisting of the hydrated calcium sulphate when calcined, it forms plaster of paris while sulfur is (uncountable) a chemical element (symbol s) with an atomic number of As a adjective sulfur is of a yellowish green colour, like that of sulfur.
Gypsum is made up of oxygen, calcium, sulfur, and water, and its chemical formula is CaSO 4 2H 2 O. Gypsum beds were formed due to the evaporation of water from the massive prehistoric sea basins.
When water evaporates, the minerals present in it become concentrated, and crystallize. “When the gypsum is applied to soils low in available sulfur or with poor physical properties, improved crop vigor and increased yields for corn, soybeans, alfalfa and wheat are commonly observed during the next growing season.
Sulfur, which has long been known to play a major role in plant metabolism (Takahashi et al., ), increases yield in common bean (Malavolta et al., ) and influences seed quality via the proportion of sulfur containing amino acids, cysteine, and methionine. Sulfate is the most significant and readily mobilized form of sulfur.
in two locations in The and gypsum applications did not improve soil infiltration rates at any of the 11 locations in and (table 3).

We want to thank Gypsoil for providing and delivering the gypsum for the and trials. Lime spreader Gypsum provides both calcium and sulfur to the soil but consistent yield. Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 2H 2 O.
It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall.A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including. For most production systems in Oklahoma there are at least 10 pounds per acre of sulfur added to the soil each year without specifically using a sulfur fertilizer.
Crop Needs. Crops need sulfur in relation to crop yield because sulfur, like nitrogen, is a mobile element in the soil.treated with gypsum the solubility of the potash in water was increased.
Likewise André (2) observed a greatly increased solubility of the potash of microcline when this was treated with gypsum. On the other hand, Fraps (6), from an extended laboratory and green- house study of the effects of additions of gypsum upon the availability.Abstract | Balanced nutrition is imperative for efficient nutrient management and has considerable role in enhancing crop yield.
To study the effect of nitrogen (N) and sulfur (S) on maize hybrids, field experiments were laid out at the Agronomy Research Farm, the University of Agriculture Peshawar, Pakistan during andrespectively.
