Soil and subsoil analyses

News

In the regions affected by chronic water deficits, the C/N (Carbon/Nitrogen) ratios are getting higher and they provoke nutritional locks, mainly between the flowering and the harvest.

Carbon Balance

It consists in measuring the quantity of carbon produced by a company for its entire activity. The measurements are perfomed on specific positions belonging to the inside activity of the company but also on the outside activity performed by companies having economical and technical links with this one.

Yearly report for 2012

After an early bud in March –April followed by a cool and rainy spring, the vines have gone through a vegetative stop in May. We observed vines in slow activity with a green-yellowish foliage showing a sudden stop of photosynthesis.

Fertilisants Cousifertyl : Analyses de sol

Following surface examination, carried out upstream to survey the vineyard (geological and mineral disparities, planting varieties, surface and subterranean hydrology, relief), comes a rigorous, unvarying and wide-reaching set of guidelines for sampling and analyses.

Sample research:

Status of sampling areas: planning
Determination of the number of pits to be dug for our observations,
Removal of earth samples, 0 to 30 cm, for soil, 30 to 80 cm for subsoil,
Identification and marking,
Rooting, density and depth,
Analyses performed by specialized laboratories, certified by the Ministry of Agriculture (AFNOR Standard), and Méthode Cousinié references.

In the laboratory:

Granulometry: structure, constituents, homogeneity, observations regarding three defined granulometric compartments,
Soil and subsoil acidity (pH)
Microbial biomass: indicates the degree of soil fertility,
Biological activity index: shows the degree of microflora quality,
Physical characterization of organic matte,
Dynamics of organic matter,
Sieve oversize,
Chemical evaluation with oligo-element,
Salinity control,
C:N ratio.

Analyses of results.
Crosschecking with data from the Méthode Cousinié Reference System.
Summary with status assessment.

Testimonials

Château Landure (Mailhac)

Carried out on the property since 1987, the Méthode Cousinié has made it possible to show the consistency of harvests from both a quantitative and qualitative standpoint, by means of adopting varieties to the terroir.

Château St Jacques d’Albas (Minervois)

After I acquired the Château St Jacques d’Albas in Minervois in 2001, I decided to call in Jean-Pierre Cousinié.

Château Tayac (Margaux)

In 1995, through the intermediary of a winegrower friend, we became acquainted with Mr. Jean-Pierre Cousinié and his method.
At our first meeting, we were won over by the conduct of this method, based on observation and highly-focused analyses, from the soil to the grape bunch.
