Our lab
We create relevant information..
for the use and sustainability of our clients' activity, analysing the quality of seeds, soil and water.
Seed Analysis
The Seed Analysis allows us to know the necessary data about the quality of the seed to ensure a good implantation of your sowing. In addition, our laboratory is approved by Don Mario Semillas to analyse the quality of the seed produced in our seedbed.
Pelayo Agronomy Laboratory is accredited by INASE (National Seed Institute).
Soil and Water Analysis
Soil analysis provides information on nutrient, water and texture content. Knowing these parameters allows a rational use of the soil and, therefore, the system to be sustainable over time.

Water and Soil Analysis
Nitrates
Quantification of N-Nitrates in agricultural soils. Method: colorimetry. Disulphonic phenol. Harper.
Phosphorus
Quantification of assimilable Phosphorus in soils. Method: colorimetry. Bray and Kurtz No1.
pH and Conductivity
Determination of pH and electrical conductivity in agricultural soils (in solution 1:2.5) by potentiometric method.
Sulphates
Quantification of sulphates in agricultural soils. Method: turbidimetry. HACH.
Organic Matter
Quantification of organic matter in agricultural soils. Method: Walkey and Black.
Young Organic Matter
Quantification of young organic matter in agricultural soils. Method: Walkey and Black.
