Phosphorus boosts Kentucky Bluegrass growth, water stress hinders - study.
The study looked at how water stress and phosphorus affect the growth of Kentucky Bluegrass in a controlled environment. They found that adding more phosphorus increased the weight of shoots and roots, but decreased the ratio of roots to shoots. Water stress hindered the growth of shoots and roots, reducing their weight and water content. The impact of water stress on Midnight Bluegrass was less severe compared to Brilliant Bluegrass.
