Liquid nitrogen fertilizer for pre-sowing application and top dressing during the growing season. It combines three forms of nitrogen and allows uniform distribution with suitable equipment. - [ATS](https://agroexperts.bg/fertilizer/ats/?lang=en): 12% N · 26% S. A liquid source of ammonium nitrogen and thiosulphate sulphur. Used on its own within a nutrition programme or as a component of nitrogen-sulphur blends with UAN. - [UAN + S](https://agroexperts.bg/fertilizer/течен-азотен-тор-със-сяра-uan-s/?lang=en): 28% N · 5% S. A liquid combination of urea, ammonium nitrate and ammonium thiosulphate. Supplies three forms of nitrogen together with sulphur for field crops, vegetables, vineyards and perennial crops. - [KTS](https://agroexperts.bg/fertilizer/kts/?lang=en): 25% K₂O · 17% S. A chloride-free liquid potassium-sulphur fertilizer. Complements nitrogen and phosphorus nutrition with water-soluble potassium and sulphur in thiosulphate form. - [CaTs](https://agroexperts.bg/fertilizer/cats/?lang=en): 6% Ca · 10% S. A liquid fertilizer supplying calcium and sulphur. Supports calcium supply, root development and fruit quality as part of a complete nutrition programme. - [APP](https://agroexperts.bg/fertilizer/app/?lang=en): 11% N · 37% P₂O₅. A liquid nitrogen-phosphorus fertilizer containing ammonium polyphosphates. In soil, these gradually convert to orthophosphates, supporting sustained phosphorus nutrition and limiting fixation of the applied phosphorus. ## Urea with inhibitors and coatings - [NitroTec® 46 Plus](https://agroexperts.bg/fertilizer/nitrotec46plus/?lang=en): 46% N. Urea with the dual urease inhibitor Limus® — NBPT and NPPT. These components slow urea hydrolysis and help limit nitrogen losses through ammonia volatilisation. - [NitroTec® 40 Plus](https://agroexperts.bg/fertilizer/nitrotec40plus/?lang=en): 40% N. A combination of urea and ammonium sulphate with the dual urease inhibitor Limus® — NBPT and NPPT. Supplies two forms of nitrogen and sulphate sulphur. - [NitroTec® 46 Max](https://agroexperts.bg/fertilizer/nitrotec46max/?lang=en): 46% N. Urea with Vibelsol® (DMPP), a nitrification inhibitor. Slows the conversion of ammonium nitrogen to nitrate and helps limit losses through leaching and denitrification. - [NitroTec® 46 Neem](https://agroexperts.bg/fertilizer/nitrotec46neem/?lang=en): Neem. Urea coated with neem oil — a plant extract from the seeds of Azadirachta indica. The coating aims to slow nitrification and retain nitrogen in ammonium form for longer. ## Other fertilizers - [NP 6:21](https://agroexperts.bg/fertilizer/течно-np-6210/?lang=en): FAST NP 6:21 liquid compound nitrogen-phosphorus fertilizer. Used as a source of nitrogen and phosphorus in nutrition programmes. - [Ammonium nitrate](https://agroexperts.bg/fertilizer/амониев-нитрат-an/?lang=en): 34.4% N. A fast-acting nitrogen fertilizer for top dressing agricultural crops. Contains ammonium and nitrate nitrogen and dissolves readily in the soil solution. - [Urea](https://agroexperts.bg/fertilizer/карбамид-urea/?lang=en): 46% N. Urea is a concentrated nitrogen fertilizer containing 46% N in urea form. Its high concentration reduces the amount of product needed to supply a given nitrogen rate. - [Monoammonium phosphate](https://agroexperts.bg/fertilizer/моноамониев-фосфат-map/?lang=en): 11% N · 52% P₂O₅. Granulated monoammonium phosphate (MAP, ammophos) for combined nitrogen and phosphorus nutrition. Uniform granules support even distribution across the soil surface. - [Diammonium phosphate](https://agroexperts.bg/fertilizer/92/?lang=en): 18% N · 46% P₂O₅. Granulated diammonium phosphate (DAP, diamophos) for combined nitrogen and phosphorus nutrition. Uniform granules support even distribution across the soil surface. - [Triple superphosphate](https://agroexperts.bg/fertilizer/троен-суперфосфат-tsp/?lang=en): 47% P₂O₅. A concentrated granulated phosphate fertilizer for basal and pre-sowing application. Suitable when phosphorus needs to be supplied separately from the nitrogen programme. - [NPK 14:14:14](https://agroexperts.bg/fertilizer/npk-141414/?lang=en): A granulated compound NPK 14:14:14 formulation from the Agroexperts catalogue for nitrogen, phosphorus and potassium nutrition. - [NPK 15:15:15](https://agroexperts.bg/fertilizer/npk-151515/?lang=en): 15:15:15 · 10% S. A compound granulated fertilizer containing nitrogen, phosphorus, potassium and sulphur. Combines all four nutrients in one granule for uniform basal nutrition. - [NPK 16:16:16](https://agroexperts.bg/fertilizer/npk-161616/?lang=en): A granulated compound NPK 16:16:16 formulation from the Agroexperts catalogue for nitrogen, phosphorus and potassium nutrition. ## Machine-readable catalogue - [English product catalogue in JSON](https://agroexperts.bg/wp-json/agroexperts/v1/products?lang=en): Current composition, specifications, descriptions and product page URLs. - [English sitemap](https://agroexperts.bg/wp-sitemap-languages-1.xml): Public English pages. - [Bulgarian version](https://agroexperts.bg/llms.txt): Bulgarian company and product information.
