V\u011bdci z Washingtonsk\u00e9 st\u00e1tn\u00ed univerzity (WSU) se chystaj\u00ed prov\u00e9st \u0161estiletou studii, v n\u00ed\u017e budou zkoumat \u00fa\u010dinky biocharu a konop\u00ed na r\u016fst a zdrav\u00ed kl\u00ed\u010dov\u00fdch plodin, jako je p\u0161enice, kuku\u0159ice a cizrna. V\u00fdzkum je podpo\u0159en grantem ve v\u00fd\u0161i $5 milion\u016f od americk\u00e9ho ministerstva energetiky a jeho c\u00edlem je prozkoumat, jak tyto dva zem\u011bd\u011blsk\u00e9 postupy mohou zv\u00fd\u0161it kvalitu p\u016fdy a produktivitu plodin.<\/p>\n\n\n\n
Biochar, produkt z\u00edskan\u00fd \u010d\u00e1ste\u010dn\u00fdm spalov\u00e1n\u00edm organick\u00fdch materi\u00e1l\u016f, jako je d\u0159evo a rostlinn\u00fd odpad, zlep\u0161uje p\u016fdu t\u00edm, \u017ee zlep\u0161uje jej\u00ed strukturu a schopnost zadr\u017eovat \u017eiviny. David Gang, vedouc\u00ed projektu a pracovn\u00edk \u00dastavu biologick\u00e9 chemie WSU, zd\u016fraz\u0148uje potenci\u00e1l biocharu ukl\u00e1dat uhl\u00edk a z\u00e1rove\u0148 obohacovat zdrav\u00ed p\u016fdy. <\/p>\n\n\n\n
Studie bude konkr\u00e9tn\u011b hodnotit r\u016fzn\u00e9 kombinace aplikace biocharu a st\u0159\u00edd\u00e1n\u00ed konop\u00ed s c\u00edlem ur\u010dit jejich kombinovan\u00fd \u00fa\u010dinek na syst\u00e9my plodin v pr\u016fb\u011bhu \u010dasu. Spolupracovat na n\u00ed budou m\u00edstn\u00ed zem\u011bd\u011blci z n\u00e1rod\u016f Yakama a Colville Reservation, jako\u017e i v\u00fdzkumn\u00edci z Pacific Northwest National Laboratory a University of Connecticut.<\/p>\n\n\n\n
Gang upozor\u0148uje, \u017ee biochar m\u016f\u017ee v\u00fdrazn\u011b zm\u011bnit vlastnosti p\u016fdy. P\u0159i aplikaci zvy\u0161uje pH p\u016fdy, zvy\u0161uje retenci vlhkosti a podporuje mikrobi\u00e1ln\u00ed aktivitu, co\u017e n\u00e1sledn\u011b pom\u00e1h\u00e1 rostlin\u00e1m v efektivn\u011bj\u0161\u00edm p\u0159\u00edstupu k z\u00e1kladn\u00edm \u017eivin\u00e1m. C\u00edlem studie je kvantifikovat tato zlep\u0161en\u00ed a jejich dopad na v\u00fdnosy plodin.<\/p>\n\n\n\n
Konop\u00ed bude hr\u00e1t v tomto v\u00fdzkumu tak\u00e9 z\u00e1sadn\u00ed roli. Konop\u00ed, zn\u00e1m\u00e9 sv\u00fdm hlubok\u00fdm ko\u0159enov\u00fdm syst\u00e9mem, pom\u00e1h\u00e1 p\u0159edch\u00e1zet erozi p\u016fdy, zlep\u0161uje jej\u00ed strukturu a dok\u00e1\u017ee odstra\u0148ovat \u0161kodliv\u00e9 kontaminanty. Gang poznamen\u00e1v\u00e1, \u017ee st\u0159\u00edd\u00e1n\u00edm konop\u00ed s jin\u00fdmi plodinami mohou zem\u011bd\u011blci zlep\u0161it celkov\u00fd stav p\u016fdy, co\u017e povede k lep\u0161\u00edm v\u00fdsledk\u016fm sklizn\u011b v n\u00e1sleduj\u00edc\u00edch vegeta\u010dn\u00edch obdob\u00edch.<\/p>\n\n\n\n
V r\u00e1mci v\u00fdzkumu bude testov\u00e1no v\u00edce d\u00e1vek a vzorc\u016f aplikace biocharu, v\u010detn\u011b kombinac\u00ed s hnojivy s \u010dasov\u011b omezen\u00fdm uvol\u0148ov\u00e1n\u00edm, s c\u00edlem nal\u00e9zt optim\u00e1ln\u00ed strategie pro zem\u011bd\u011blsk\u00e9 postupy.

C\u00edlem je vytvo\u0159it model, kter\u00fd uk\u00e1\u017ee v\u00fdhody integrace konop\u00ed a biocharu do zem\u011bd\u011blsk\u00fdch postup\u016f, co\u017e by mohlo m\u00edt z\u00e1sadn\u00ed v\u00fdznam pro revitalizaci degradovan\u00e9 p\u016fdy v regionech, jako je rezervace Colville a dal\u0161\u00ed posti\u017een\u00e9 oblasti.<\/p>\n\n\n\n
Gang vyjad\u0159uje dlouhodobou vizi t\u00e9to pr\u00e1ce: \"Pot\u0159ebujeme p\u016fdu, kter\u00e1 udr\u017e\u00ed na\u0161i schopnost u\u017eivit se.
