Using gypsum as a soil amendment is the most economical way to cut the non-point
run-off pollution of phosphorus.
Major benefits of gypsum for Agriculture
- Source of calcium and sulfur for plant nutrition.
- Improves acid soils and treats aluminum toxicity.
- Improves soil structure.
- Improves water infiltration.
- Helps reduce runoff and erosion.
Where agri gypsum required
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. But when
soil becomes acidic, the aluminum is available to plants—and it can stunt or kill
them.
Another bonus of gypsum is that it is a moderately-soluble mineral. This means the
calcium can move further down into the soil than the calcium from lime (calcium
carbonate). This can inhibit aluminum uptake at depth and promote deeper rooting
of plants. When roots are more abundant and can grow deeper into the soil profile,
they can take up more water and nutrients, even during the drier periods of a growing
season.
Gypsum can also help improve soil structure. Many of us look at soil as a uniform,
static substance. In reality, soil is a mixture of inorganic particles, organic
particles, and a complex mixture of pore spaces, water, and soil microbes. Its composition
changes through weather events like rainstorms, by tillage, or as plants pull nutrients
for growth. Farmers have to manage their soil well in order to maintain good crop
yields year after year.
