Evidence and opinion

Mineral nutrition, pasture and management, explained plainly.

Every figure published here carries its public source alongside. What we cannot verify, we do not write.

  1. Field management Water and trough: the pair that decides mineral intake The best formulation on the market is worth nothing if the animal never reaches the trough, or does not drink. Intake is management before it is nutrition. Redação técnica · · 5 min read · Embrapa
  2. Mineral nutrition Cobalt, copper, zinc and selenium: what each one does in the herd They are required in milligrams and they decide in arrobas. Trace minerals do not fatten the animal: they make work the things that do. Redação técnica · · 5 min read · Embrapa · MAPA
  3. Label and regulation How to read a mineral supplement label The label is not packaging: it is a document. It states what the product contains, how much, and how it should be fed. Redação técnica · · 6 min read · MAPA
  4. Column Bag price is the worst way to compare minerals Comparing supplements by the price of the packaging is comparing what matters least. The sum that decides is not on the invoice: it is at the trough. Magnata do Sal · · 4 min read · Opinion
  5. Mineral nutrition Phosphorus in tropical pasture: why it runs short first Of all the minerals pasture ought to deliver, phosphorus is usually the first to run short. And the shortfall does not show up overnight. Redação técnica · · 5 min read · Embrapa
  6. Pasture and dry season What changes at the trough in the dry season In the dry season pasture does not just shrink: it changes quality. And what was right in the wet season stops being right. Redação técnica · · 5 min read · Embrapa · INMET
  7. Column The label is a contract, and almost nobody reads it before signing Everything a manufacturer promises fits on the back of the bag. It is the only place he can be held to, and it is the least read text on the farm. Magnata do Sal · · 4 min read · MAPA
