• Effluent irrigation Growers of aspen trees for pulpwood may wish they could “latch onto*’ irrigation water from the nearest municipal sewage plant. Experiments at The Penn sylvania State University have found that aspens irrigated with sewage ef fluent reach marketable size 12 to 14 years sooner than aspens not irrigated.

Increased fiber length in the irrigated trees produced a better fiber length to width ratio, considered an ad vantage to pulp strength. The experiments were carried out by Dr. Wayne K.

All trees sampled were 10 to 13 inches in diameter at breast height. Irrigation was continuous from 1965 to 1973 when growth and fiber length of irrigated and unirrigated trees were compared.

Average annual growth in the crowns (tops) was significantly larger than at the mid-boles or the bases. Trees were sampled from the interior of treated and untreated stands to avoid border effects. Earlier studies at Penn State showed the value of recharging ground water reserves with effluent. FARM-AID MIXER Water and nutrient benefits to field crops have likewise been proven.
