Liquid Fertilization of Public Fishing Lakes in Alabama

Liquid ammonium polyphosphate fertilizer (Poly NR) was evaluated at state-owned public fishing lakes in Alabama. Initial evaluation indicated that only one-third the quantity of phosphate that would normally be applied in granular fertilizer (9 kg/ha P20 5 ) to fishing lakes was necessary to produce acceptable Secchi disc visibilities (≤ 60 cm) during the fertilization season. Further evaluation at 20 public fishing lakes demonstrated that significant financial savings could be achieved in conjunction with acceptable Secchi disc visibilities with a liquid fertilization program.
