However, nutrientcontents of shrubs vary significantly with climate, soil and especially with plant growth. There are a few studieson annual variations in mineral contents of shrubs in Marmara Region. Therefore, in this study, seasonal variationof macronutrients (N, P, K, Ca, Mg, S) of kermes oak (Quercus coccifera L.), mock privet (Phillyrea latifolia L.),prickly juniper (Juniperus oxycedrus L.), gall oak (Quercus infectoria Oliv.), Christ's-thorn (Paliurus spina-christiMiller), pink rockrose (Cistus creticus L.), thyme (Thymus longicaulis C. Presl.) and prickly burnet (Sarcopoteriumspinosum (L.) Spach) were investigated for 14 months (October 2006-November 2007). Variation of macronutrientsthroughout the year was found to be significant for all shrubs. The concentrations of N, P, K, and S in the shrubsreached the highest levels during the April-May months. However, Ca significantly decreased in April. Variationin Mg varied with shrub species. While the amount of N was able to meet the demands of goats during spring forall shrubs except for Paliurus spina-christi and Quercus infectoria, they were not able to meet the demands inother seasons. While Paliurus spina-christi had sufficient N every season, Quercus infectoria had also sufficientN during each season except for winter. P, K, and Ca were mostly observed at sufficient amounts for goats. WhileJuniperus oxycedrus had insufficient Mg in every season and mock privet in summer and autumn, Mg deficiencywas not observed in other shrubs. Amounts of S were generally insufficient for the needs of goats.eninfo:eu-repo/semantics/closedAccessMacronutrients; Shrubby rangelandArticle9843573662-s2.0-84855752856Q3
