Kwita ku gihingwa cy'Iinanasi

• Gufumbira: Kubera ko umuhinzi aba yarashyize mu murima w’inanasi amafumbire nk’uko byasobanuwe haruguru, gufumbira inanasi ziri mu murima bigamije kuzongerera imyunyu ya Azoti (N2) na Potasi (K2O) igihe hagaragaye ko ziyikeneye.
• Gufata neza igihingwa:Nyuma yo gutera inanasi ubundi nta mirimo ivunanye isabwa cyane cyane iyo wateye kuri plasitki yirabura nk’uko byavuzwe haruguru. Nyamara kugirango uzabone umusaruro mwiza kandi ku bihe abaguzi bifuriza inanasi ni ngombwa kuzikorera ibi bikurikira :

• Gusura kenshi umurima: Ni ngombwa ku muhinzi wa kijyambere gusura umurima we w’inanasi kugira ngo arebe icyo ukeneye. Indwara n’ibyonnyi byaba bitangiye kubifata agatabarira bugufi nta kironona umusaruro aba ategereje.
• Kurwanya ibyatsi byimeza mu murima

Kuva ugitera inanasi kugeza mu musaruro wa kabiri, umurima ugomba guhora buri gihe ufite isuku. Umuhinzi agomba rero guhora akuramo ibyatsi byose, haba mu mirongo cyangwa mu tuyira. Ku bahinzi babigize umwuga mu kurwanya ibyatsi uretse kubiranduza intoki cyangwa isuka bakoresha n’imiti yabigenewe. Mu gutegura umurima bashobora no gukoresha imiti ya kabuhariwe (Aminitriazol, paraquat, glyphosate, dalapan na Bromacil ku gipimo cya kg 2 kugeza kuri kg 5 kuri hegitari 1.

• Kwihutisha irabya ry’inanasi

Mu buryo busanzwe inanasi irabya mu bihe by’iminsi y’amanywa magufi kandi iyo minsi ikaba ifutse. Ariko ubu havumbuwe imiti itera inanasi kurabya igihe bikenewe. Kwihutisha irabya ry’inanasi bituma umuhinzi abona mu musaruro inanasi zifite uburemere yifuza. Iyo uteye umuti wo kurabisha mu gihe inanasi yari hafi yo kurabya, ubona urubuto runini naho uwuteye inanasi itarageza igihe cyo kurabya ubona urubuto rutoya. Ibyo kandi bituma ku nanasi zifite ikigero kimwe zishobora gusarurirwa rimwe ku murima umwe. Imiti ishobora gukoreshwa ni amoko atanu (5) ariyo aya akurikira :

• Asetilene (Acetylène)
• Etilène
• Etefo

• Gusimburanya no kuvanga inanasi n’ibindi bihingwa

Nk’uko byavuzwe haruguru nyuma y’umusaruro wa kabiri ni ngombwa kwimura inanasi zigaterwa mu wundi murima. Ahavuye inanasi hahingwa nk’uko byavuzwe ibinyamisogwe kuko birwanya inzoka z’ibihingwa kandi bigaha ubutaka umunyu wa Azoti. Muri ibyo binyamusogwe ndumburabutaka twavuga nka Crotalariya, imikunde, teforoziya n’ibindi……Iyo ushaka kuzakoresha uwo murima mu gihe cya vuba wasimbuza inanasi mukuna, vese cyangwa soja.
