The agricultural practice of manure cropping can result in the accumulation of surplus phosphorus (P) in soils with consequent losses by leaching. Two Italian alfalfa landraces originating from intensive (“Cremonese”) versus extensive (“Senese”) cattle farming regions were studied in order to investigate their variation for (a) efficiency in exploiting different P sources–farm dairy effluents (FDE), phytic acid (Phy), and inorganic P (IP)–in a lysimeter trial, and (b) the sequence of the MsPHY1 gene, which encodes a root extracellular phytase, releasing inorganic P for plant growth.

两种意大利紫花苜蓿（Medicago sativa）地方品种的有机磷利用效率不同，涉及编码MsPHY1基因的植酸酶的可能适应模式

粪肥耕作的农业实践可能导致土壤中多余的磷（P）积累，并因淋溶而流失。为了研究它们在（a）利用不同磷源的效率方面的差异（a）利用不同的P来源-农场乳制品废水（FDE），植酸，研究了两个意大利的紫花苜蓿地方品种，它们分别来自集约化（Cremonese）和广泛化（Senese）养牛地区。 （Phy）和无机P（IP）–在溶渗仪试验中，以及（b）Ms PHY1基因的序列，该基因编码根细胞外植酸酶，释放无机P用于植物生长。
