Bodembenutting4input output

Bodemvruchtbaarheid bepaalt5

Bemesten naar potentieResultaten : Abbink & Baars, in preparation 6

Bodemvruchtbaarheid en opbrengst

Bemesten naar potentie8 Of alle percelen evenveel bemesten?9

Waarmee wordt de bodem gevoerd?10

Mestonderzoek pakketjes11

Bodemvruchtbaarheid verbeteren

Potentie verhogen

Voorbeeld: org stof = 4,3%; aantal = 700180 kg K2O Potentie verhogen14

50 60% masland pH < 5

Geen pH onderzocht:35% grasland10% bouwland

Bodembenutting start met kennisbenutting!Bemest naar potentie/perceelsgerichtWeet wat er bemest wordtZorg dat pH op peil isBodemvruchtbaarheid is de basis.

Voer en dierbenutting16

Optimaal rantsoen?17

Voer en dierbenutting18Eigen voer eerst!

Wat is nu een topkuil?19

20

Cijfers liegen niet.maar somsVanuit de koe naar een kuil kijken21

Pens is de basis22

Het principe23

23Directe meting24

Penskarakter van de kuil A 12% B 30 % c: 21 % D 11% optimum 26%25

Sturen op pensbenutting26

Wat willen we?27

Wat is het optimale DS gehalte?Sturen met DSVEM: 890, RE: 175, NDF:495 28Sturen met DSVEM: 890, RE: 175, NDF:495

29Sturen met DSVEM: 890, RE: 175, NDF:495

30Kuil met vergelijkbare voederwaarde 880 VEM 31

Zoek de verschillen: Gelijke VEM 880 32

Kuil 1Kuil 2De ervaringen van de boerKuil 1Melkproductie vrij goed, viel erg meeMest aardig goed, maar beter met droge 2e snede

Kuil 2Melkproductie viel tegenErg dikke gehaltes (7500 kg, 5% vet 4% eiwit)Dikke mest, te weinig eiwit dacht hij, maar wilde niet corrigeren i.v.m. quotumoverschrijding.

33

Andere individuele factoren op pensverteringGraslandkwaliteit

Seizoens-effect

Inkuilproces

Bemestingsniveau

34

Droger inkuilen 40-50%35

Vochtiger inkuilen 30-45 %36

DS en VCOS Finland (550-575 NDF)37Een nieuwe kijk: Effect op bewaring?38Topjaar ook topkuilen?39

Kuilen 2014: snel verteerbaar40Kuilen van dit jaar goed benutten41Kuilen van dit jaar goed benuttenLangzame energie bronnen

Bestendige eiwit bronnenKuilen bevatten veel onbestendig eiwitBronnen als soja gunstige RE/P verhouding.

Kuilen compenserenRustige kuilen als compensatie gebruikenEventueel structuurbron gebruiken

42SamenvattendZorg voor hoge voerefficintieEigen voer eerst!Bemest naar potentie/perceelsgerichtWeet wat er bemest wordtZorg dat pH op peil is

Goede boerenpraktijk = goed mineralenmanagement

2020 Boer of mineralenmanager?44

De boer = goeie manager 45
