Interaction of added Gypsum in Alkaline Soils with

2019-7-27 · an interaction operates in plant uptake between Fe and Mo in alkaline soils. Other experiments have shown that Mo uptake was reduced in plants by increasing sulfate levels in the soil (Stout et al., 1951; Reisenauer et al., 1963; Gupta and Munro, 1969; Jones and Ruckman, 1973). Therefore, a gypsum treatment was included to test an

Short-term effects of biochar and gypsum on soil hydraulic ...

2020-10-1 · Salt and sodicity of saline-alkali soil adversely affect the construction of ecological landscapes and negatively impact crop production. The reclamation potential of biochar (BC, wheat straw biochar applied at 1% by weight), gypsum (G, 0.4% by weight), and gypsum coupled with biochar (GBC) was examined in this laboratory-based study by evaluating their effects on a saline-alkali soil (silt ...

Improving Soil With Gypsum - Garden.org

In most situations gypsum has little effect on soil pH. Use limestone to raise pH of acid soils, and elemental sulfur to lower pH of alkaline soils. However, if soil is alkaline because of high bicarbonate ions, or if irrigation water contains bicarbonate, the soluble calcium in gypsum reacts with the bicarbonate to form insoluble calcium ...

2019-2-6 · Gypsum will change soil pH very slightly, yet it can promote better root development of crops, especially in acid soils, even without a big pH change. This is because the gypsum counteracts the toxic effect of soluble aluminum on root development. Aluminum occurs naturally in soil and often isn’t a problem for crops.

Notes on the Gypsum Requirement (GR) of Soil

2021-11-12 · This article provides a notes on the Gypsum Requirement (GR) of soil. The main principle for the reclamation of sodic or alkali soils is to replace exchangeable Na by another cation calcium (Ca 2+).Of all calcium compounds, gypsum (CaSO 4.2H 2 O) is considered the best and cheapest for the reclamation purpose. Calcium (Ca 2+) solubilized from gypsum replaces sodium (Na +) leaving
