Fertility studies reveal plant & soil needs

Proper fertilization is important in realizing the great potential from the annual grasslands of California. One of the first studies indicated that forage production on improved dry-land pasture fertilized with nitrogen and phosphorus increased ten-fold over untreated pastures during the winter months of feed shortage. In another study it was found that fertilized pastures yielded about 3 1/2 times as much meat and wool as unfertilized pastures over the growing seas on.
