Engessul agricultural gypsum is used as a soil corrector
and conditioner, as a source of calcium and sulfur nutrients
and to increase the calcium/magnesium ratio of soils.
Thanks to its great solubility, (145 times higher than
limestone), the gypsum penetrates in the deepest layers
of soils (under-surface), thus complementing the benefits
of liming, which acts only on the surface layer (up to
increasing soil porosity and neutralizing toxic aluminum,
agricultural gypsum allows the deepening of roots, which
in turn have a greater amount of available nutrients and
water for their development and to withstand drought and
hot spell periods. The Engessul agricultural gypsum does
not need to be incorporated into the soils and may be
applied only on the surface, being easily solubilized
and incorporated into the soil by the rain.
incorporation of calcium and sulfur deep into the soil
favors root growth, enhances plant vigor and improves
food value, thus allowing greater productivity and increasing
the quality of harvested products.
Engessul agricultural gypsum is also used as a conditioner
in the fermentation of manure, allowing greater nitrogen
retention and enriching the compound with calcium and
some soils, be it by their own nature or by the intensive
use of dolomitic limestone, the calcium/magnesium (Ca/Mg)
ratio presents lower-than-desirable values. The problem
correction with the use of calcitic limestone causes the
pH to increase, which is often undesirable. The utilization
of Engessul agricultural gypsum allows the problem to
be corrected without altering the pH values.
to its capability of increasing soil porosity, the Engessul
agricultural gypsum has been used to fight problems of
surface crusting of soils, caused by the loss of organic
matter and by the impacting action of raindrops, machinery
traffic and animal trampling. Crusting increases surface
runoff and erosion as it keeps the water from seeping
through the soil, aside from impairing seedling emergence,
especially leguminous ones.
this characteristic of the agricultural gypsum, the product
has been utilized to increase surface permeability of
sanitary sewer decantation basins, thus increasing the
seepage rate of liquid effluents.
