·However effects of gypsum application were less apparent than those of lime application and the combination of surface lime Mg ha −1 and gypsum 9 Mg ha −1 application yielded the greatest long term increase in the stock of total organic C stock Thus the results of the present study suggest that lime and gypsum application along
·Gypsum application induced a reduction in CH 4 emissions with increasing gypsum application rate Our results indicate that gypsum application could increase rice yield and reduce greenhouse gas emissions providing a theoretical basis for evaluating the effects of gypsum application on high rice yield and mitigating global warming
·1109 Gypsum is commonly used as a soil amendment and as a fertilizer in agriculture In fact it is one of the earliest forms of fertilizer used in the United States and its use dates back more than 200 yr Wallace 1994 Gypsum is an excellent source of calcium Ca and sulfur S for plant nutrition as Ca2 and SO4 2− ions become readily available in soil solution
·The application of FGD gypsum also increased the salt tolerance of salt tolerant plants Combined with drainage laser field levelling and tillage decreased soil salinity by more than % and increased the yield of oil sunflower by up to % This study provides convincing evidence of the benefits of the application of the six treatments
·In this work we have reinvestigated the thermal degradation kinetics of synthetic gypsum CaSO4·2H2O using a novel approach based on peak deconvolution followed by the application of Model Free isoconversional method Gypsum was prepared using wet chemical route and characterized by conventional X ray diffraction in situ high temperature X
·Natural gypsum can be used in concrete production as a replacement for calcium aluminate cement CAC opening the possibility of replacing the natural gypsum with FGDG in this application with success even though some studies have reported a reduction of compressive strength and water solubility when compared to conventional cement mixtures
·The instability of mine pillars has posed a serious threat to the safety of mines in China In order to reduce the risk of pillar instability this study used fiber reinforced polymer FRP to reinforce gypsum specimens and conduct mechanical loading experiments The study investigates the reinforcement effect of gypsum specimens with different height diameter
·The effect of different rate of gypsum fertilizer addition on rice plant performance and methane CH 4 emission was evaluated for saline paddy rice soil by a pot experiment for 30 days There were four treatments; control gypsum 1 G1 and 2 G2 ton ha − 1 with 3 replications Gypsum application led to a significant decrease in pH and an increase in EC
·You can t base a gypsum application on a routine soil test because it wasn t designed to make a gypsum recommendation A soil test measures water pH and buffer pH and this information is used to determine a lime recommendation to correct an acid soil pH A soil test can calculate a soil s cation exchange capacity and that information
·Our results suggested that grafting had more influence than gypsum application on cucumber growth under saline water irrigation and was an effective approach in alleviating crop salt stress Introduction The population in China has increased to nearly billion people in 2014 and it still shows an increasing trend To support the increased
·Adding gypsum to the soil reduces erosion by increasing the ability of soil to soak up water after precipitation thus reducing runoff Gypsum application also improves soil aeration and water percolation through the soil profile A recent study showed the benefit of gypsum application to improve movement of water through the profile to tile
·On the other hand gypsum is moderately water soluble and anhydrite its associated anhydrous mineral changes volume and swells when exposed to water Yılmaz 2001 Strength loss due to dissolution along with swelling due to wetting should be considered in the strength limit and service limit designs of soils treated with gypsum/anhydrite as well as
· Experimental design In this study plots without the application of amendments were used as controls and FGD gypsum 15 t/ha LH FGD gypsum 30 t/ha LA FGD gypsum 15 t/ha and aeolian sand 15 t/ha mixed FL aeolian sand 15 t/ha FH aeolian sand 30 t/ha FA and the control without the application of the amendment CK with a total
·Similarly at the Wooster site gypsum application at Mg ha 1 and Mg ha 1 rates increased soil S concentrations by 4 and 7 fold respectively compared to the control Gypsum application has been found to increase soil S levels even at much lower rates than were applied in this study Chen et al 2008; Kost et al 2014 On the
·Gypsum s unique chemical makeup makes it a particularly valuable mineral The presence of two water molecules in its structure is crucial as this characteristic allows it to undergo a process known as calcination When heated gypsum loses its water and becomes calcium sulfate hemihydrate commonly known as plaster of Paris a material known
·The frequency of gypsum application can vary based on your soil s condition and needs Generally applying gypsum once or twice a year in the spring and fall is sufficient for most lawns 6 How much gypsum should I apply to my lawn The application rate can vary depending on the product and your soil s specific requirements
·The Gypsum application amount varies with the requirements of the soil and somewhat with the crops being raised Since Gypsum is a Soil Amendment as well as an excellent source of Calcium and Sulfur your existing soil structure will need to be known That said within certain geographies we can estimate the application volume based on the
·1 Introduction Gypsum has been widely used throughout human history because it is a binder with good technical properties [1] Above all it is abundant as it can be extracted in its natural form as well as be generated synthetically as a by product of industrial processes for example phosphogypsum fluorogypsum citrogypsum desulfogypsum
