Mulch
SOLPLAST PREVENTS THE RISK OF HIGH TEMPERATURES ON THE SOIL
O
ne of the most relevant technological innovations of mulch over time has been the multilayer extrusion to develop two-colour films. Surely the most common bicolour within this range is the white/black combination whose white face reflects solar IR radiation while its black face guarantees maximum opacity to control or fight weeds. We performed a comparative experience in a field of strawberries on the coast of Peru which provided very interesting conclusions. Our objective was to measure the soil temperature difference between the ridges covered with White/Black mulch and those covered with Black mulch. The test was conducted between the months of March and June of the year 2018, collecting close to 100,000 soil temperature records which we summarize below:
