The formulation addresses a specific stage: growth slows, while the turf still needs to maintain its physiological functions.<\/p>\n<h2 style=\"margin: 34px 0 16px!important; padding: 0!important; color: #222!important; font-family: Arial,Helvetica,sans-serif!important; font-size: 28px!important; line-height: 1.3!important; font-weight: 700!important; text-transform: none!important; letter-spacing: normal!important;\">What happens to turfgrass before winter dormancy?<\/h2>\n<p style=\"margin: 0 0 18px!important; padding: 0!important; color: #222!important; font-family: Arial,Helvetica,sans-serif!important; font-size: 18px!important; line-height: 1.7!important;\">As days shorten and temperatures fall, cool-season grasses gradually reduce shoot growth and begin to acclimate to cold conditions. During this transition, tissue water balance changes, along with the concentration of cellular solutes, including sugars and potassium ions.<\/p>\n<p style=\"margin: 0 0 18px!important; padding: 0!important; color: #222!important; font-family: Arial,Helvetica,sans-serif!important; font-size: 18px!important; line-height: 1.7!important;\">Cool-season turfgrasses can enter a state of <strong style=\"font-weight: 700!important; color: inherit!important;\">semi-dormancy<\/strong>, with shoot growth slowing before root activity declines. The extent of this slowdown depends on species and climate. DUO supports the turf during this transition, while the plant is still able to use nutrients.<\/p>\n<p style=\"margin: 0 0 18px!important; padding: 0!important; color: #222!important; font-family: Arial,Helvetica,sans-serif!important; font-size: 18px!important; line-height: 1.7!important;\">Pre-winter fertilization takes place within this physiological window, before nutrient uptake stops. A well-timed nitrogen application supports leaf tissue that remains photosynthetically active and contributes to the management program for building plant reserves.<\/p>\n<h2 style=\"margin: 34px 0 16px!important; padding: 0!important; color: #222!important; font-family: Arial,Helvetica,sans-serif!important; font-size: 28px!important; line-height: 1.3!important; font-weight: 700!important; text-transform: none!important; letter-spacing: normal!important;\">DUO 18-0-15 + 2 Mg: nutrient composition<\/h2>\n<p style=\"margin: 0 0 18px!important; padding: 0!important; color: #222!important; font-family: Arial,Helvetica,sans-serif!important; font-size: 18px!important; line-height: 1.7!important;\">DUO is a phosphorus-free formulation that supplies nitrogen and potassium alongside magnesium:<\/p>\n<table style=\"width: 100%!important; border-collapse: collapse!important; margin: 20px 0!important; font-family: Arial,Helvetica,sans-serif!important; font-size: 17px!important;\">\n<thead>\n<tr>\n<th style=\"text-align: left!important; padding: 12px!important; border: 1px solid #d8e3d8!important; background: #edf5ed!important; color: #222!important;\" scope=\"col\">Nutrient<\/th>\n<th style=\"text-align: left!important; padding: 12px!important; border: 1px solid #d8e3d8!important; background: #edf5ed!important; color: #222!important;\" scope=\"col\">Nutrient content<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding: 10px 12px!important; border: 1px solid #d8e3d8!important; color: #222!important; line-height: 1.5!important;\">N<\/td>\n<td style=\"padding: 10px 12px!important; border: 1px solid #d8e3d8!important; color: #222!important; line-height: 1.5!important;\">18%<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px 12px!important; border: 1px solid #d8e3d8!important; color: #222!important; line-height: 1.5!important;\">Nitrate nitrogen<\/td>\n<td style=\"padding: 10px 12px!important; border: 1px solid #d8e3d8!important; color: #222!important; line-height: 1.5!important;\">3%<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px 12px!important; border: 1px solid #d8e3d8!important; color: #222!important; line-height: 1.5!important;\">Ammoniacal nitrogen<\/td>\n<td style=\"padding: 10px 12px!important; border: 1px solid #d8e3d8!important; color: #222!important; line-height: 1.5!important;\">9.5%<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px 12px!important; border: 1px solid #d8e3d8!important; color: #222!important; line-height: 1.5!important;\">Controlled-release nitrogen<\/td>\n<td style=\"padding: 10px 12px!important; border: 1px solid #d8e3d8!important; color: #222!important; line-height: 1.5!important;\">5.5%<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px 12px!important; border: 1px solid #d8e3d8!important; color: #222!important; line-height: 1.5!important;\">K\u2082O<\/td>\n<td style=\"padding: 10px 12px!important; border: 1px solid #d8e3d8!important; color: #222!important; line-height: 1.5!important;\">15%<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px 12px!important; border: 1px solid #d8e3d8!important; color: #222!important; line-height: 1.5!important;\">MgO<\/td>\n<td style=\"padding: 10px 12px!important; border: 1px solid #d8e3d8!important; color: #222!important; line-height: 1.5!important;\">2%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p style=\"margin: 0 0 18px!important; padding: 0!important; color: #222!important; font-family: Arial,Helvetica,sans-serif!important; font-size: 18px!important; line-height: 1.7!important;\"><small>The percentages of the individual nitrogen forms refer to the product and add up to 18% total nitrogen.
