Enwere ike iji ihe mkpuchi ala mee ka ala dara ogbenye dịkwuo mma, ma ọ bụ wughachi ala nke mebiri emebi site na njikwa ala na-ezighi ezi. Ha nwere ike ime ka ala na-adịghị mma na-eji ya eme ihe, enwere ike iji ya mee ka ala dị n'ogo dị elu.

## Ihe ndị mejupụtara ya
A kọwawo ihe dị iche iche dị iche iche dị ka ihe na-edozi ala n'ihi ike ha na-eme ka mma ala dị mma. Ụfọdụ ihe atụ gụnyere biochar,[3] nri ọkpụkpụ, nri ọbara, ogige kọfị, compost, tii compost, coir, nri, [4] ahịhịa, peat, sphagnum moss, vermiculite, sọlfọ, lime, hydroabsorbant polymers, [5] na biosolids.

Ọtụtụ ihe nkpuchi ala na-abịa n'ụdị ngwaahịa organic akwadoro, maka ndị mmadụ na-eche maka idobe ihe ọkụkụ organic ma ọ bụ ubi ahịhịa.

### Polyacrylamides
A na-enyocha polyacrylamides n'ọtụtụ ebe dị ka ihe na-edozi ala.[8] Ewebata ha dị ka "linear ala conditioner" na 1950 site Monsanto Company n'okpuru ahia aha Krilium. E gosipụtara nkà na ụzụ nhazi nke ala na nnọkọ mkparịta ụka na "Mmelite nke Ọdịdị Ala" nke e mere na Philadelphia, Pennsylvania na Disemba 29, 1951. Edebere nkà na ụzụ ahụ nke ọma na e bipụtara ya na mbipụta June 1952 nke akwụkwọ akụkọ Soil Science, olu 73, June 1952 nke a raara nye maka ihe mkpuchi ala polymeric. Nhazi mbụ nke polyacrylamide ala conditioners siri ike iji n'ihi na ọ nwere calcium nke jikọtara polymer linear n'okpuru ọnọdụ ubi. Monsanto gbahapụrụ Krilium. Ndị na-edozi ala na-edozi mmiri na-enye uru ndị a:
