Fertilizer / NPK Fertilizers
Liquid fertilizer
Liquid complex fertilizer (APP) is actually a water solution of ammonium phosphates and it contains two nutrient components, such as nitrogen and phosphorous in ratio of 11:37. Phosphorous is contained in APP as tribasic and polyphosphates in fully assimilable form. Liquid complex fertilizer is a transparent greenish-bluish liquid which actually does not contain insoluble residues and suspensions.
APP (11-37) is a highly efficient, fast-acting fertilizer. Apart from condensed phosphates (70-80% of the total mass of P2O5) and nitrogen, APP contains sulphur and magnesium. All the nutrient compounds are in a solution, therefore they are easily accessible for plants. APP possesses high efficiency for all types of crops, in all regions, especially on calcareous soil.
Use of APP has indubitable advantages over solid fertilizers, as high uniformity of application of nutrients to soil is achieved, their losses are reduced and conditions of work are improved. Extra nutrition with APP solutions may be combined with treatment of coil with microelements and with plant protection means. APP should be applied using the same methods as the ones for solid fertilizers, i.e. distributing it over the soil surface prior to ploughing and cultivation, locally at sowing, as well as for extra nutrition of agricultural crops. APP is used for capsulation and pelleting of seeds, their presowing treatment.
The fertilizer does not contain harmful admixtures and it fully complies with increased environmental requirements.
The product was repeatedly granted with honorable awards at international and Russian exhibitions-fairs. APP was awarded the Golden Quality Mark at the all-Russia contest “All-Russia Brand. Quality Mark of the 21st Century”.
