Alforex Seeds by DLF

Alforex Seeds by DLF™ offers a leading alfalfa lineup for North America, featuring elite genetics and technologies. Known for high yield and nutritional value, it supports greater productivity with advanced breeding and rigorous quality testing.
Hi-Salt®

Hi-Salt® alfalfa varieties were developed for high saline areas in North America, as higher salt concentrations in the soil can lead to seedling loss. Through focused breeding, these varieties are able to mitigate the effects by reducing salinity by 2.0 to 3.0 EC (electrical conductivity) points. This cutting-edge technology allows growers to plant alfalfa in areas previously considered unsuitable.
