Tässä julkaisussa esitetään tuloksia laajasta valtakunnallisesta tutkimuksesta, jossa verrattiin monivuotisissa kenttäkokeissa vuosittain annettujen kaliummäärien vaikutuksia peltokasvien sadon määrään ja laatuun sekä maan viljavuuteen. Tavoitteena oli viljan, nurmen, rypsin ja perunan kaliumlannoituksen optimoiminen eri maalajeilla kemiallisten maa- ja kasvianalyysien avulla. Ilman kaliumlannoitusta tuotettu sato vaihteli eri kokeissa välillä 28-100 % riittävällä kaliummäärällä saadusta sadosta. Lisätty kalium paransi kasvua eniten niukkaravinteisella turvemaalla viljellyllä nurmella, jonka sadoissa poistui runsaasti ravinteita. Savimaiden ravinnevarat riittivät nurmellakin useiksi vuosiksi täyteen satoon ilman kaliumlannoitusta. Vilj...
