Introduction
Biodegradable mulch films have become a common practice in agriculture. Their characteristics in terms of
environmental impact (biodegradation in soil and ecotoxicity) have been indicated in EN 17033,
Biodegradable mulch films for use in agriculture and horticulture – Requirements and test methods.
In order to complete the characterization of these materials, this technical report gives information on a
procedure for sampling and measuring the occurrence of a damage on the biodegradable mulch film when in
use in the field [1].
It is recommended to collect the agronomic and weather information of the mulched area. The information
collected does not alter the procedure described.
This document may be used to assess the surface integrity of the biodegradable thermoplastic mulch film
during its service life.

1 Scope
This document gives guidance for the quantification of alteration of biodegradable thermoplastic mulch films
for use in agriculture and horticulture.
It can be used for biodegradable thermoplastic mulch films in conformity with EN 17033.

requirements of this document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 17033 and the following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

3.1
alteration
alteration of the film in anyway either confined to a well-defined and attributed to a specific cause or
distributed on the whole surface of the film
Note 1 to entry: Alterations not considered due to the characteristics of the material, are all those injuries caused by
animals or particularly violent weather events (storms, hail, wind, etc.) or mechanical damage accidentally caused by
objects, equipment improperly used or man-made (trampling, damages done by tools, other similar).
3.2
damage
alteration that affects more than 10 % of the surface of the sampled areas of a mulch film
3.3
row
succession of plants placed at a uniform and defined distance
4 Principle
The alteration incurred by a biodegradable mulching film is represented by the interruption of the
continuity of the surface and the consequent exposure of the underlying soil.
Applying the provisions of agrarian evaluation [2], the evaluation of the alteration of a biodegradable
mulching film is comparable to the valuation of the damage caused by hail, or by pathogenic foliaceous
agents. Therefore, it is possible to operate by performing visual examinations and photographic surveys by
using the analytical procedure described in this document.
The quantification of the alteration is performed through visual examinations and photographic surveys if
necessary. The number of zones to be sampled might be determined following national regulations, if any
[3].

The visual examination is a tool for quick evaluations that helps determine the type of alteration (systematic
and widespread or localized) and, if systematic and widespread, its percentage of incidence on the surfaces
analysed.
The photographic survey, once defined that the alteration is systematic and widespread through the visual
examination, allow confirming, in the areas of sampling the measurement of the percentage of film missing.
5 Sampling method
The sampling of the area to be surveyed shall be performed in accordance with the rules of block
randomization design scheme.
The block randomization scheme is the most widely applied scheme in agronomical tests and consists in
dividing the area under observation in sub-areas. This allows to have the maximum homogeneity among the
sub-areas and at the same time are differentiated as possible between them. The block randomization
scheme offers the possibility to control the effects of heterogeneity of the mulching film, improving the
power of the observation and allows eliminating the experimental error variability between the blocks.
Concerning the arrangement and the shape of the blocks, in the case of detection of the alteration of a
mulching film placed on a soil, it is assumed not to have information about the fertility gradient or the
damage on the same film. For this reason it is not possible to define gradients resulting detection and
randomization shall be carried out according to Clause 6.
The visual examinations and the photographic surveys shall be
