Mixing the dry inoculum with the seed without moistening the seed will fail more times than it will succeed. Legumes for pasture use Ladino. The easiest legume to establish in most grass sods is ladino clover. Ladino will grow on almost any soil that is well supplied with phosphorus, potash and lime. It is high in quality and a heavy nitrogen fixer.
Ladino has two serious drawbacks.
It is more likely to cause bloat than other legumes and it does not produce well during the dry summer months. It is somewhat less drought tolerant than most other legumes but has more drought tolerance than is commonly believed. Red clover is relatively easy to establish and has many desirable characteristics needed for a pasture legume. It will grow on a relatively wide range of soils. It is of high quality, does not present the high bloat risk of ladino or alfalfa and has medium drought tolerance.
