Gypsum Effect in Reducing Aluminum Toxicity
Effect of Gypsum in Reducing Aluminum Toxicity Almost 50% of the potentially arable lands in the world are faced with the acidification problem. Use of the agricultural gypsum in the soils with the high aluminum concentration, such as the soils in lands under the tea cultivation and those near dried up swamps used in the […]
Saline and alkaline soils and their grading
Amending saline and alkaline soils procedure The main problem in amending alkaline soils is their degraded structure and toxicity resulting from the sodium presence. First step in amending such soils is to apply large amounts of calcium in form of small calcium sulfate particles. (several tons per hectare) to displace sodium by calcium. The smaller […]
Agricultural gypsum benefits
Gypsum benefits And importance of its application Gypsum is one of the first fertilizers used by the farmers throughout the world. In the some places it has been used as a fertilizer for about 250 years. Gypsum has moderate solubility in water (2.5-2.6 g/L). Its solubility is much greater compared to compounds. such as lime […]
Agricultural gypsum Effects on soil salinity and pH
Soil salinity and pH, which are among the very important factors in agricultural efficiency, will be discussed next Agricultural gypsum effects on soil salinity Water and soil salinity inflict considerable losses on agricultural and horticultural production. Among the dominant soil cations, sodium ions have a direct relationship with salinity. i. e, increases in soil salinity […]
Gypsum effect application on soil fertility
Gypsum effect application on soil fertility If confirmed by laboratory results, and despite entailed cost, gypsum application is necessary and must be priority among farming practices. Essentially, increased calcium concentration in soil solution in anyway, such as by gypsum application, can cause formation of insoluble compounds. containing phosphorus or micronutrients thus making them unavailable to […]
Agricultural gypsum particle size distribution
Agricultural gypsum particle size distribution When using gypsum, the particle size of the gypsum used must be considered. Smaller gypsum particles dissolve faster. Of course, given the cost of this work, the size choice depends on economic issues. and this does not mean that the use of powder agricultural gypsum can have the best result […]
Gypsum properties suitable for soil amendment
Suitable gypsum properties Gypsum, no matter how it is used, must be applied with the heavy irrigation. So that the sodium released from the exchange surfaces leaves the root zone along with the irrigation water. Important point is water volume required for dissolving specific gypsum amount usually calculated based on gypsum solubility in free water. […]
Applying agricultural gypsum rules
Applying agricultural gypsum rules When and how to apply agricultural gypsum As in all other soil amendments, it is better to apply gypsum during plant dormancy or in autumn or winter. Of course, under right conditions and sufficient water presence, gypsum can be applied to soil in any season of year. Gypsum has average solubility […]
Gypsum, the soil conditioner
Gypsum, the soil conditioner Correcting materials used for soils with high magnesium or sodium can basically be divided into two main groups. The first group –e. g. gypsum- add “calcium” ions to soil solution directly, and the second group –e. g. various acids or sulfur- reduces soil acidity which results in lime dissolution in soil […]
Soil recognition and analysis
Soil recognition and analysis, after the use of agricultural gypsum Soil Analysis and Plant Nutrient Needs Soil analysis is a crucial tool for determining the specific nutrient requirements of plants. By conducting a thorough soil analysis, you can identify the materials and nutrients that your plants need, as well as the extent to which these […]
