One of the main factors considered in assessing the nutritional value of feed is its chemical composition, which can be modified by fertilization. Faced with reducing P resources, alternative sources of this element are being sought. Phosphorus is an essential nutrient in soybean cultivation. The aim of the study was to use an alternative source of phosphorus fertilizer and compare its impact on the chemical composition of soybean seeds with that of a traditional fertilizer (Super FOS DAR). The study investigated a range of factors in animal nutrition as well as the basic content of macro- and microelements. A pot experiment with the Abelina soybean variety was conducted at the Experimental Station of the Wroclaw University of Environmental and Life Sciences. The experiment considered two factors against the control: phosphorus fertilizer placement (band, broadcast) and different phosphorus fertilization (Super FOS DAR, Crystal Green). Use of struvite (Crystal Green)) caused positive changes in selected amino acids content and in the nutritional value of protein in soybean seeds; this can enhance the value of soybean seeds as well as increase certain macroelements and microelements. Phosphorus fertilizer significantly increased the content of lysine, leucine, valine, phenyloalanine and tyrosine. Band fertilization with struvite caused a significant increase in amino acids (lysine, leucine, valine, phenyloalanine and tyrosine) as well as in the nutritional value of protein (as measured by the essential amino acid index, protein efficiency ratio and biological value of the protein). Favorable changes under the influence of the application of struvite were recorded in the content of calcium, as well as phosphorus, iron, and manganese. The value of the struvite in the case of its use as phosphorus fertilizer is promising; however, it needs further study.
评估饲料营养价值的一个主要因素是其化学成分，而化学成分可以通过施肥来改变。面对磷资源的减少，人们正在寻找这种元素的替代来源。磷是大豆种植的一种必需营养物质。本研究的目的是使用替代来源的磷肥，并将其对大豆种子化学组成的影响与传统肥料（Super FOS DAR）进行比较。该研究调查了动物营养的一系列因素以及大量和微量元素的基本含量。在弗罗茨瓦夫大学生物与环境科学实验站进行了 Abelina 大豆品种的盆栽试验。该试验考虑了两个因素，即：磷肥的施用（条施、撒施）和不同的磷肥（Super FOS DAR、Crystal Green）。使用鸟粪石（Crystal Green））导致了所选氨基酸含量和大豆种子中蛋白质营养价值的积极变化；这可以提高大豆种子的价值，并增加某些大量元素和微量元素。磷肥显著增加了赖氨酸、亮氨酸、缬氨酸、苯丙氨酸和酪氨酸的含量。鸟粪石条施显著增加了氨基酸（赖氨酸、亮氨酸、缬氨酸、苯丙氨酸和酪氨酸）以及蛋白质的营养价值（通过必需氨基酸指数、蛋白质效率比和蛋白质生物学价值来衡量）。在鸟粪石施用的影响下，钙、磷、铁和锰的含量也发生了有利的变化。鸟粪石作为磷肥的应用具有很大的潜力，但需要进一步研究。
