The #Nizza soils.

27 marzo 2015

The territory where #Nizza is produced can be divided in four subzones,  characterised by different types of soils.

Sandy soils.
This area is made up of the municipalities of Vinchio, Cortiglione and Incisa Scapaccino as well as part of Mombercelli and Mombaruzzo.
The soil consists of highly permeable fine and coarse sands; the area lacks fertiliy and is poor in organic substances.

Sandy and marly soils.
This area is made up of the municipalities of Castelnuovo Calcea part of Agliano an Mombercelli,  part of Nizza Monferrato,  Castelnuovo Belbo and part of Mombaruzzo. The soils consists of moderately permeable sands and marls.

Silty and marly soils.
This area is made up of the municipalities of Agliano, Moasca, San Marzano Oliveto, and Castel Rocchero, part of Castel Boglione and part of Nizza Monferrato. The soil consists of silt and marl with a fairly small amount of permeable clay.

Sandy soils and sandstone.
This includes the municipalities of Calamandrana,  Rocchetta Palafea and part of Castel Boglione.
Here we find quite highly permeable marl and sandstone.

The Nizza hills are set at an altitude of between 150 and 350 metres above sea level.
In most of the areas, the soil depth and consequently the root extension are quite high.
Only area 4 is shallower due the presence of a strongly cemented substratum.
Area 1 can present scant irrigation in low rainfall years, although this is mitigated by the presence of silt. Oxygen is generally abundant, as the hill slope favours water drainage even in less permeable soil.
