Agrotechnical procedures for establishing the potato crops in relation to water resource protection

Popis výsledku v původním jazyce

Limitation of using pesticides and fertilizers in water resource protection zones also applies to potato growers. Due to insufficient options of weed control with herbicides in potatoes working tools were designed and developed for mechanical weed management prior to emergence and at the beginning of potato crop emergence. The tools are intended for using in the de-stoning technology. Developing the working tools, an emphasis was placed to the gentle soil loosening in addition to weed destruction to prevent the support of soil mineralization processes, increase in CO2 emissions and soil water loss after more intensive soil aeration. The weed-killing efficacy of this measure was 6 % decreased compared to using of a pre-emergent herbicide. The combination of mechanical destruction and a post-emergent herbicide was 4 % increased compared to the conventional treatment. Similar results were also obtained for potato yield. Potatoes are often grown on sloped fields. To guarantee better retention of water from precipitation and erosion control small pits and tied ridges could be formed in the non-trail furrow and/or liquid mineral fertilizers could be applied into the potato root zone. This procedure results in reduced erosion risk and water resource contamination with herbicide residues, nitrates and other undesirable substances.
