Kalcifikacija

Povratak

Godišnji gubici kalcija zbog ispiranja moraju se nadoknaditi. Također se moraju neutralizirati sve kiseline koje se unose u tlo oborinama, kiselim gnojivima i sl. Ako se to ne učini, plodnost tla će se svake godine pogoršavati.

Održavanje sadržaja kalcija u tlu i pH vrijednosti na odgovarajućoj razini naziva se održavajuća kalcifikacija. Održavajuća kalcifikacija trebala bi se obaviti svake godine ili barem svake 2-3 godine.

Kako bismo saznali koliko je vapna potrebno za održavajuću kalcifikaciju, napravili smo kalkulator za procjenu potrebne količine. Na temelju istraživanja dr. C.M.J. Sluijsmans ( Institut za plodnost tla Nizozemska)
