Long and eco long

Supply of nutrients matched to crop growth! Coated Fertilizers

Long" and "Ecolong" are coated fertilizers that adjust the leaching of fertilizer components according to the growth of the crop. ECOLONG" and "ECOLONG" are granular nitrate compound fertilizers (such as phosphorus nitrate potassium, NK compound, nitrate lime, etc.) coated with a specially processed membrane made mainly of polyolefin resin and inorganic minerals. In addition, the film of ECOLONG has photodisintegrability and microbial degradability.
　The mechanism of leaching of fertilizer components and their leaching characteristics with respect to temperature are similar to those of urea-coated "LP Coat" and "M Coat," and are largely unaffected by soil pH and soil moisture.
　Contains nitrate-form nitrogen that works well for general field crops. It has a long-lasting fertilizing effect, allowing cultivation using only base fertilizer. Local application of fertilizer increases the efficiency of fertilizer use and makes it possible to reduce the amount of fertilizer used.
　There are two types of leaching type: linear type (linear leaching begins immediately after fertilizer application) and sigmoid type (Super (Eco) Long, Super NK (Eco) Long), in which leaching begins after initial leaching is suppressed for a certain period of time. The number of days in which 80% of nitrogen is leached in soil at 25°C is used for the name. The brand name can be selected to match many applications for field crops by differences in fertilizer components (chisso, phosphorusan, and potash), number of days of elution, and elution type.
