Correcting Soil Problems with Amendments

Effective soil management is crucial for optimal crop growth, and this guide explores the use of amendments such as lime, gypsum, and organic matter to correct various soil problems. Acidic soils often hinder nutrient availability and require lime for correction. Saline and sodic soils, characterized by excessive sodium, can be improved with sulfur-based amendments and proper irrigation techniques. Understanding how to manage these soils, including selecting salt-tolerant crops and utilizing effective drainage, is essential for sustainable agriculture.

Presentation Transcript

    1. Correcting Soil Problems with Amendments Problem soils need to be managed by adding; Lime Gypsum Sulfur Organic Matter

    2. Acid Soils Toxic due to aluminum & manganese Alters activities of microorganisms involved in N and S transformation in the soil. P availability is greatly reduced. Usually low in Calcium & Magnesium

    3. Tolerance to Acidity Know the four levels and some crops in each.

    4. Correction of acid soil Add Lime Refer to Table 10-2 & 10-3

    5. Saline & Sodic Soils (Alkali) Soils contain excessive amounts of sodium.

    6. Correction of Saline soil Sulfur, Sulfuric Acid, Ferric sulfate, Lime sulfur, Aluminum sulfate, & Ammonium polysulfide. Leaching with high quality irrigation water. Note gypsum, organic matter, manure, & crop residue.

    7. Management of Saline & Sodic soils Refer to page 249 (salt tolerant crop, drainage, irrigation, tillage methods, chemical amendments, ect.)
