Ohakandozi

Ohakandozi, ba zamin andokhtani ohak va digar nurihoi ohakdor bo maqsadi bartaraf kardani turshii barziyod, ki baroi numui beshtari ziroathoi khojagii qishloq zararnok ast; usuli meliorasiyai khimiyavii khoki tursh. Ohakandozi prossessest, ki dar natichai on dar khok ionhoi gidrogenu allyuminiy ba ionhoi kaliy va magniy ivaz mesha­vand. Hangomi Ohakandozi dar natijai raf gardidani turshii khok va ziyod shu­dani miqdori kalsiy faoliyati mikroorganizmhoi mufid avj megirad. Dar natijai in khok az moddahoi gizoii baroi rastani dastras boy gardida, khosiyati fizikii on behtar meshavad. Ohakandozi nurihoi organi­ki va mineraliro samarabakhshtar menamoyad.

Ohakro odatan ba zaminhoi khokash khokistari, chimtolu khokistari, torfkhok va bazan ba khoki  khokistarrangi jangal va surkhkhok meandozand. Meyori istifodai ohak az rui turshii hok, tarkibi mekhanikii on va khususiyathoya ziroat muqarrar karda meshavad. Ohakandozi baroi sabzishu nashunamoi aksari ziroathoi khojagii qishloq ahamiyati kalon dorad. Dar na­tichai Ohakandozi hosili ziroat khele ziyod meshavad (dar SSSR ba hisobi miyo­na senr/gektar): galladona (don) 0,5—4; lubiyoiho (don) 1—3; lablabui khuroki chorvo 30—60; kartoshka 5—15; zagirpoya 1—3; sebarga 7—15; karam 30—70; sabzi 15—45. Baroi muvofiqi plan tashkil namudani Ohakandozi tadqiqi makhsusi khok, dar sahro guzaronidani tajribahoro ba roh monda, kartogrammai turshii khokro tartib medihand.
