Monoammonium phosphate is a commonly used fertilizer for better crop production. However, its repeated application causes the accumulation of harmful metals levels in plants and soil over time. Here, the impact of the purification of monoammonium phosphate fertilizer on vegetative growth and yield of tomato plants (Lycopersicon esculentum L.), and the heavy metals accumulation in both soil mix and tomato fruits was investigated through a pot experiment on three different concentrations of purified and unpurified monoammonium phosphate fertilizer. This study showed that the purification of monoammonium phosphate led to a significant enhancement on vegetative growth and yield attributes, mainly for 1 g/L of purified fertilizer. Importantly, the physicochemical investigations showed a significant reduction in heavy metals accumulation (Pb, Cr, Cd, Ni, and V) in the fruits and the soil mix treated with purified monoammonium phosphate. This study confirms that the use of purified monoammonium phosphate fertilizer improves the fruit yield and at the same time reduces the impact of toxicity of heavy metals present in the environment, which can be classified as a part of an environmental management systems.

纯化的磷酸一铵肥料可提高产量并减少番茄(Lycopersicon esculentum L.)中的重金属积累

磷酸一铵是提高作物产量的常用肥料。但是,随着时间的推移,其重复使用会导致植物和土壤中有害金属含量的积累。在此,纯化磷酸一铵肥料对番茄植物营养生长和产量的影响(番茄)L.),并通过盆栽试验,对三种不同浓度的纯化和未纯化磷酸一铵肥料进行了土壤混合和番茄果实中的重金属积累研究。这项研究表明,磷酸一铵的纯化导致营养生长和产量属性的显着提高,主要是针对1 g / L的纯化肥料。重要的是,理化研究表明,用纯磷酸一铵处理过的水果和土壤混合物中的重金属积累(Pb,Cr,Cd,Ni和V)显着减少。这项研究证实,使用纯化的磷酸一铵肥料可提高水果产量,同时减少环境中存在的重金属的毒性影响,
