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 […]
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 […]
Agricultural gypsum application in saffron fields
Agricultural gypsum application benefits Investigation of the mechanism of agricultural gypsum in reducing the soil salinity of saffron fields shows that there is no time limit for adding gypsum to the soil and it can be done at any time. We should also add gypsum to the soil when heavy irrigation is possible. If the […]
Gypsum effect on sodium soils modification
Sodium soils modification According to the definition of the American Salinity Laboratory (1954), sodium soil is soil whose percentage of exchangeable sodium (ESP) is greater than 15%. But in a study by Norscott and Chisen (1972), the researchers showed that if the soil ESP was greater than 6, it would affect the physical properties of […]
Gypsum and saline and alkaline waters usage
lands irrigation procedure Use of gypsum and saline and alkaline waters used to irrigate lands Irrigation of agricultural lands using saline and alkaline waters will reduce the quality of soils in these lands. so that after a few years of irrigation with saline water, it will cause the non-use of such lands. In such cases, […]
Adding Gypsum to Lime-Rich Soils Impacts
Impacts of Adding Gypsum to Lime-Rich Soils Gypsum increases the quality of products Gypsum is one of the best sources of calcium and sulfate for plants. that need calcium, including peanuts, tomatoes, wheat, corn, citrus, and so on. However, calcium deficiency is evident in most calcareous soils. where it is among the leading cause of […]
