Yellow sweet clover grows best on moist and loose soils, in places that are heavily exposed to sunlight.
Sowing 18-25 kg/ha, 30-40 cm apart. The plant is valued for its good growth on barren, stony, sandy, degraded soils, in frost reservoirs, where other small-seeded legumes and noble grass varieties froze.
Cultivated for green manure, especially for root crops. Currently, yellow melilot is increasingly sown in areas contaminated with dioxins for soil phytoremediation. It also strengthens slopes, embankments and ditches well.
