Agricultural alabaster plaster anhydrous 0.01 / 0.1 mm (25 kg)

ALCOHOLIC AGRICULTURAL ALABASTRINE PLASTER 0.01 / 0.1 mm (25 Kg).

Anhydrous agricultural chalk; this gypsum is worked industrially and precisely, after being cooked at high temperatures it completely loses all the water molecules contained in the crystal lattice. This process makes it suitable for modifying the pH of soils (increases the pH of very acid soils and lowers the pH of very basic soils.

Gypsum is a sedimentary rock of evaporitic origin, the main constituent of which is the mineral of the same name (which consists of calcium sulphate dihydrate). The rock is formed by precipitation of calcium sulphate through the evaporation of sea water.

FUNCTIONAL CHARACTERISTICS AND FIELDS OF USE

Natural inert material, ideal for:

? raising the pH in soils with high acidity (for example in soils with pH <5), ie used as a corrector of non-saline alkaline soils and alkaline-saline soils; or it lowers the pH of too basic soils (for example in soils with pH> 7). To correct the alkalinity of the soil, distribute evenly over the entire surface of the soil and incorporate the corrective in the first 15 cm. Surfaces with appropriate processing. It is a good idea to carry out this operation before the rainy period, so as to entrust the percolation water with the task of bringing the corrective substance more deeply. For conservative interventions, annually use 15-20 Ql / Ha (0.15-0.20 kg per m2) of gypsum distributed in the usual way. To obtain the opposite effect of that of gypsum, lime must be used;

? make significant improvements to the production yield in many crops in soils deficient in calcium and / or sulfur;

? tubular soil drainage systems to eliminate water stagnation in alkaline soils;

? fungiculture as an indispensable additive for obtaining an ideal substrate.

NB: NEWS ON PACKAGING

It should be noted that the package visible in the photo has an "opening pocket" in the top part, it is an opening in the bag that is folded up internally in order to prevent the plaster from coming out, despite this, this particular type of packaging (which allows the user to let the plaster come out of the bag without having to cut it once the "opening pocket" has been explained) always allows the release of a few grams of product found inside the box that our employees use as packaging for shipping the bag . We want to underline this aspect as it is not unclear in the packaging, but it is precisely a constructive feature used by the manufacturer of the bag itself.

NB: NEWS ON THE USE OF THE PRODUCT FOR BUILDING PURPOSES

It should be noted that gypsum for sale is a gypsum for agricultural use which therefore CANNOT be used in the construction field or to build molds because it does not have the technical characteristics useful for these purposes.
