RAMIREZ-LOZANO, Roque G.; CANTU-SILVA, Israel; GOMEZ-MEZA, Marco V.  e  GONZALEZ-RODRIGUEZ, Humberto. Mineral content in leaf litter of Tamaulipas thorny scrub. Ecosistemas y recur. agropecuarios [online]. 2018, vol.5, n.13, pp.119-125. ISSN 2007-901X.  https://doi.org/10.19136/era.a5n13.1034.

The objective of the study was to evaluate and compare in space and time the concentration of Ca, K, Mg, P, Cu, Fe, Mn and Zn in litter collected in the municipality of Linares, Nuevo León, Mexico. The contents of all minerals, except Cu and Zn, were statistically different among sites, months and interactions. Ca ranged from 23 to 43 g kg-1 dry basis, K was from 3 to 9, Mg from 2 to 4 and P from 0.2 to 1.1. Cu varied from 4 to 7, Fe from 103 to 654, Mn from 22 to 42 and Zn from 12 to 25 mg kg-1. The content of Mg, P, Cu and Zn is not enough to satisfy the metabolic requirements of ruminants.
