PLANTS for SALINE to SODIC SOIL CONDITIONS

Soil amendments such as gypsum, calcium chloride dehydrate and sulfuric acid have been used for reclamation of saline-sodic soils. These amendments generally involve the replacement of exchangeable sodium with calcium. For amendments to be effective, the displaced sodium must be leached out of the plant rooting zone.

Sodic or Alkaline Soil? Calcine® Can Help. | Midwestern BioAg

Sodic or Alkaline Soil? Calcine® Can Help. Improve Soil Structure and Productivity with Calcine. When added to irrigation water, Calcine mobilizes salts out of the root zone and improves soil productivity. Reducing soil salinity improves soil health by increasing water-holding capacity and infiltration, reducing compaction and boosting rates ...

What Is the Difference Between Saline & Sodic Soils ...

Definition. Saline and sodic soils both have high pH levels, with problems typically occurring at a pH of 7.8, or extremely alkaline conditions. The primary difference is that saline soils also have a high salt content, while sodic soils have high sodium content. Soils may also have both high salt and sodium contents at the same time.

Definition of Saline-Alkali (Sodic) Soils: Saline (Solonchak, Russian Term) Soil: Saline soils defined as a soil having a conductivity of the saturation extract greater than 4 dSm -1 (0.4 Sm -1 or 4 mmhos cm -1) and an exchangeable sodium percentage (ESP) less than 15. The pH is usually less than 8.5.

Solutions to Soil Problems: High pH - eXtension

Oct 26, 2015 · Alkaline Soils. Soils may be alkaline due to over- acidic soils. Also, alkaline irrigation waters may cause soil alkalinity and this is treatable, but alkaline soils are primarily caused by a calcium carbonate-rich parent material weathering (developing) in an arid or dry environment.

2. Non-saline Sodic Soils: Soils in which electro conductivity of saturation extract of soil is less than 4 desisimens per metre (ds/m), exchangeable sodium is more than 15 per cent and pH value of soil is more than 8.5 are called non-saline sodic soils.

Alkaline Soil and Plants That Don't Mind Alkalinity

Fortunately, just as there are plants that like acidic soils, which give you planting options on sour ground (when you can't -- or do not want to -- raise the soil pH), so there are plants that like alkaline soil (or, at least, do not mind growing in it).Observe, however, that even plants within the same genus can "disagree" over what kind of ground that they like to grow in.
