Liquid complex fertilizers (LCF 11:37) are an water solution of ammonium phosphates containing two nutrients: nitrogen and phosphorus in the ratio 11:37. Phosphorus in LCF is present in the form of ortho- and polyphosphates, in a completely digestible form. Liquid complex fertilizer is a transparent, greenish-bluish liquid, which practically does not contain insoluble residues, suspensions.
LCF (11-37) is a highly effective, high-speed fertilizer. In addition to condensed phosphates and nitrogen, the HCS contains sulfur, magnesium. All nutrients are in solution, therefore they are easily accessible to plants, they also have high efficiency in crops of any crop, in all regions of Ukraine, especially on carbonate soils.
Transportation, storage: LCF does not contain free ammonia, so they can be stored and transported in leaking containers.
The LCF lacks the drawbacks inherent in solid fertilizers. They have free flowing, do not dust, do not croak, the wet weather, and rain do not have any influence on them. This basic fertilizer is often used to produce triple LCF of various compositions, by adding cold urea, ammonium nitrate and potassium chloride, fertilizers can be produced with the required ratio of active substances.
Phosphorus-containing liquid suspension complex fertilizers SLCF NP (S) 6:24 (2), NP (S) 8:22 (10) are aqueous solutions of nutritive salts with different ratios of nitrogen, phosphorus, sulfur. Nutrient components in SLCF are contained in the form of the same salts as in classical dry fertilizers. Salt fertilizer system is a collection of monoammonium phosphate (ammophos), diammonium phosphate and ammonium sulfate.
Fertilizers are not aggressive, do not contain free ammonia, acidity level of the suspension is 5,8 ÷ 6,5 units, density is 1,3 ÷ 1,4 kg / dm3, white-yellow-greenish shade.
The application of SLCF is carried out with the help of equipment for applying liquid mineral fertilizers. Fertilizer is applied to the required depth, while presowing or continuous cultivation of the soil is carried out simultaneously.
