Emkhakheni wokukhiqiza ezolimo nocwaningo lwesayensi, kubalulekile ukubamba kahle izimo zenhlabathi. Inzwa yenhlabathi engu-8 ku-1, ezokwethulwa namuhla, isiphenduke isandla sokunene sabasebenzi abaningi abanemisebenzi yayo enamandla.
Ithuluzi lokukhulisa umkhiqizo emapulazini amakhulu
Epulazini elikhulu lokulima ukudla e-Australia, isivuno bekunzima ukugqobhoza esikhathini esidlule ngokuthembela kokuhlangenwe nakho kwemisebenzi yokulima. Lokhu kwashintsha kakhulu lapho kwethulwa inzwa yenhlabathi engu-8 ku-1. Le nzwa inokunemba okuphezulu kakhulu, ingaba nembe kakhulu ngesikhathi esifanayo ukuqapha inhlabathi i-pH, i-nitrogen, i-phosphorus ne-potassium okuqukethwe, umswakama, izinga lokushisa kanye nezinye izinkomba eziyisishiyagalombili ezibalulekile, ukunikeza ukusekelwa kwedatha okuthembekile kubalimi. Ukuzinza kwayo kuhle kakhulu, futhi ngeke kube khona ukuchezuka kwedatha ngenxa yokuguquguquka okuncane endaweni ezungezile, okuqinisekisa ukuphuma kwedatha okuzinzile yesikhathi eside. Ngaphezu kwalokho, kulula ukuyifaka, ngaphandle kwamathuluzi ochwepheshe ayinkimbinkimbi kanye nenqubo ende yokuthuma, abasebenzi basepulazini bangaqedela ukufakwa kalula.
Ngokusekelwe kudatha yempendulo yenzwa, umlimi angakwazi ukulungisa ngokunembile uhlelo lokuvundisa. Lapho inzwa ibonisa ukuntuleka kwe-nitrogen enhlabathini, nedatha yayo enembile, umlimi angakwazi ukwengeza umanyolo we-nitrogen ngesikhathi esifanele nangendlela efanele, egwema imfucuza kanye nokungcoliswa kwenhlabathi okubangelwa ukuvundiswa okungaboni. Mayelana nokunisela, inzwa yenhlabathi engu-8 ku-1 idatha yesikhathi sangempela somswakama womhlabathi, ukuze abalimi bakwazi ukuhlela ngokunengqondo isikhathi sokunisela namanzi, ukuze kuqinisekiswe ukuthi izitshalo zihlala zisendaweni engcono kakhulu yokukhula. Ngokuhamba konyaka, ukukhiqizwa kokudla kwepulazi kunyuke ngo-25%, kodwa izindleko zehle ngo-15%, futhi inzwa yenhlabathi engu-8 ku-1 ibe ukhiye wokwandisa iholo lepulazi.
Umngane onakekelayo wabathandi bezingadi basemadolobheni
Ezingadini ezisophahleni lwasemadolobheni nasezitshalweni ezincane ze-horticultural, indawo ilinganiselwe, futhi izimo zenhlabathi zinzima kakhulu. UMnu. Lee, othanda ingadi, ufake inzwa yenhlabathi engu-8 koku-1 engadini yakhe esophahleni. Incane, kulula ukuyifaka, kodwa inamandla. Angabona izinkomba zomhlabathi ngesikhathi sangempela kusuka kumakhalekhukhwini wakhe. Lapho etshala izimbali, lapho izinzwa zithola ukuthi inhlabathi i-pH ayifanele ukukhula kwezimbali, ngokushesha wenza ukuthuthukiswa kwenhlabathi ukuze aqinisekise ukuthi izimbali ziyachuma. Ngenzwa yomhlabathi 8 ku-1, ingadi igcwele izimbali nezithelo, futhi omakhelwane banomona futhi bamcela iseluleko.
Ukwesekwa okunembile kwamaphrojekthi ocwaningo lwesayensi
Iphrojekthi yocwaningo lwezolimo eyunivesithi yaseNdiya yayidinga ucwaningo olunzulu ngokukhula kwezitshalo ezindaweni ezihlukahlukene zenhlabathi. Inzwa yomhlabathi 8 ku-1 idlala indima ebalulekile. Ngalo, abacwaningi bathole inani elikhulu ledatha yenhlabathi enembile, enikeza ukusekela okuqinile kokutadisha ukuguquguquka kwezitshalo ezimweni ezihlukahlukene zenhlabathi. Isibonelo, ocwaningweni lwezinhlobonhlobo zezitshalo ezintsha, ngokusho kwedatha yezinzwa, abacwaningi bathola ukuthi ukuhlukahluka ngaphansi kwezimo ezithile zokushisa kwenhlabathi kanye nomswakama, ukuthuthukiswa kwezimpande kungcono, ngaleyo ndlela kunikeze isisekelo sesayensi sokuthuthukisa uhlelo lokutshala, nokukhuthaza inqubekelaphambili eshelelayo yephrojekthi yocwaningo lwesayensi.
Noma ngabe ukukhiqizwa kwezolimo ngezinga elikhulu, ukutshalwa kwezitshalo ezincane, noma amaphrojekthi ocwaningo lwesayensi aqinile, inzwa yenhlabathi engu-8 ku-1 ingadlala inani elikhulu ngamakhono ayo okuqapha aphelele nanembile. Uma futhi ukhathazeka ngokuqapha nokuphatha izimo zenhlabathi, zama lenzwa emangalisayo yenhlabathi engu-8 ku-1 ukuze uqale uhambo lokutshala nokucwaninga olusebenzayo nolwesayensi.
Uma unenkinga,
sicela uxhumane nonjiniyela wethu, uMarvin
