Soil sampling
Samples will be taken at regular time intervals, before during and after the cultivation period, from different demonstration fields. During each sampling campaign a total of 10 samples will be randomly obtained from each field and sampling layer to ensure data accuracy.
Sampling from the surface soil (0-5, 5-10, 10-15 and 20-25 cm) will be performed using stainless steel cylinders suitable for undisturbed soil sampling. Soil samples from deeper layers (30-40, 50-60 and 70-80 cm) will be obtained using a hand auger.
