Correcting poor soil structure conditions with an application of gypsum can have a significant impact on soil tilth and crop yields. However, many producers overlook this practice because they are not aware of the benefits to soil structure as well as a readily available source of calcium and sulfur. One...
Yellowing of crop leaves? It could be iron chlorosis.
Gypsum can help remediate iron chlorosis. Iron chlorosis is a yellowing of plant leaves caused by iron deficiency. However it is not always a true iron deficiency but rather an iron tie-up in plants and soil. Yellow leaves indicate a lack of chlorophyll, the green pigment responsible for photosynthesis (sugar...
Phosphorus retention in crops and how calcium can play a role
It’s a dichotomy – the impact of calcium on phosphorus retention and availability. Fields that receive large amounts of manure or litter contain large amounts of phosphorus. Phosphorus that isn't taken up by plants remains in the subsoil and is displaced by runoff. If it isn’t tied up by soil...
