Annual and seasonal changes in mineral contents (Ca, Mg, P, K and Na) of grazed clover-grass mixtures in organic farming	2006	12	.pdf	application/pdf	8161	381	65	In this study the effect of seed mixture (alsike clover, red clover, white clover, white and alsike clover or grass mixture), year (1997, 1998) and grazing period (5 per grazing season) on the herbage calcium (Ca), magnesium (Mg), potassium (K) phosphorous (P) and sodium (Na) contents was assessed and the relationships between botanical proportions and herbage mineral contents were studied. The relationship between botanical proportions and herbage mineral content was as- sessed using Spearman correlation.	cache/afs-5826.pdf	txt/afs-5826.txt
