Power Land line products are granular NPK Controlled Release Fertilizers (CRF). The nitrogen inside is released to the circulating solution through a biodegradable polymeric membrane up to 3 months, without being affected by neither pH or soil bacteria. These products allow a better efficiency for their fertilizing elements supplied and, at the same time, they allow the reduction of applications during the full vegetative growth phase. Power Land line fertilizers are characterized by low chlorine content with potassium sulphate, magnesium and micronutrients, particularly suitable for soil applications of every crop in greenhouses and open fields. They can be used both before ploughing as well as in post-transplanting for localized application, guaranteeing in both cases a good fertilizing effect.
