Abstract

fetched live from OpenAlex

I ett projekt med medel fran Jordbruksverket studerades effekterna pa utlakningen av kvave och fosfor av eftersadda fanggrodor (sadda efter skord av huvudgrodan) i ett utlakningsforsok pa sandig mojord vid L:a Boslid i Halland. I det 3-ariga faltforsoket odlades vitsenap (Sinapsis alba) och oljerattika(Raphanus sativus) efter farskpotatis (skord i juni) och varkorn. Nedbrukning av fanggrodan skedde antingen sent pa hosten eller pa varen. Som referens till leden med eftersadda fanggrodor odlades varkorn utan fanggroda med bearbetning sent pa hosten samt sommarpotatis (skord i augusti) som efterfoljdes av ragvete som fanggroda. Utlakningsmatningar i de specialdranerade forsoksrutorna kompletterades med vaxt- och jordprovtagningar vid strategiska tidpunkter. Efterverkanseffekter av fanggrodorna studerades i efterfoljande varkorn. Ovanjordiskt kvaveupptag under hosten i fanggrodorna efter varkorn och sommarpotatis uppgick till omkring 10 kg N/ha, medan den tidigare sadda fanggrodan efter farskpotatis tog upp ca 30 kg N/ha. Kvave- och fosforutlakningen efter varkorn med fanggroda var oforandrad jamfort med ledet med varkorn utan fanggroda, oberoende av bearbetningstidpunkten. Kvaveutlakningen var hogst i ledet med sommarpotatis foljd av ragvete. I ledet med oljerattika efter farskpotatis fanns sannolikt en reduktion av kvaveutlakningen som darmed hamnade pa samma niva som leden med varkorn. I leden med fanggrodor efter varkorn och efter sommarpotatis var medelskorden hos efter-verkansgrodorna nagot storre an i leden med varkorn utan fanggroda och oljerattika efter farskpotatis, men skillnaderna var ej signifikanta.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
