Zusammenfassung

TLDRDie video bespreek die uitdagings van boerdery in 'n laagliggende gebied, waar oorstromings en nat weer 'n groot probleem is. Die boer gebruik minimum grondbewerking om die basisgras te behou en die pH van die grond te bestuur, wat tussen vier en vyf is. Die bestuur van dreinering is van kardinale belang om oorstromings vinnig te verwyder, terwyl die suurlaag van die grond klam gehou word. Die boer werk saam met die plaaslike owerhede om die floodgates te verbeter, wat help om die vloei van water te optimaliseer en die omgewing te beskerm.

Mitbringsel

  • 🌧️ Uitdagings sluit oorstromings en nat weer in.
  • 🌱 Minimum grondbewerking help om die basisgras te behou.
  • ⚖️ Die pH van die grond is tussen 4 en 5.
  • 🚰 Dreinering is noodsaaklik om oorstromings vinnig te verwyder.
  • 🔧 Verbeterde floodgates help om water vinnig te laat vloei.

    Die boer en sy span verbou beesvleis en oes gras saad, maar hulle ondervind uitdagings soos oorstromings en lang periodes van nat weer. Die grond is laag, wat beteken dat selfs 'n klein rivier kan lei tot oorstromings op hul weivelde. Hulle het 'n spesifieke tipe grond, bekend as suur sulfaatgrond, wat 'n lae pH het. Om die grond se gesondheid te verbeter, gebruik hulle minimum grondbewerking en hou die basisgras gevestig. Hulle bestuur ook die water tafel deur die vloedgate, wat noodsaaklik is om oortollige water vinnig te verwyder, maar hulle moet versigtig wees om nie te veel grondvog te verloor nie. Die skoonmaak van die dreineringstelsels is 'n prioriteit om die water vinnig van die weivelde af te kry. Hulle het saam met die raad en visserye gewerk om vloedgate te herbou, wat 'n groter opening het om water vinniger te laat vloei, terwyl dit steeds die suur laag in die grond vogtig hou.

Video-Fragen und Antworten

  • Wat is die hoofuitdagings vir die boer?

    Die hoofuitdagings sluit oorstromings en lang periodes van nat weer in.

  • Hoe beïnvloed die grondsoort die boerdery?

    Die grond het 'n hoë suurvlak, wat die pH tussen vier en vyf hou.

  • Wat is minimum grondbewerking?

    Minimum grondbewerking behels die behoud van die basisgras en die vermyding van oortollige bewerking.

  • Waarom is dreinering belangrik?

    Dreinering is belangrik om oorstromings vinnig te verwyder en om die grondvochtigheid te balanseer.

  • Wat is die rol van die floodgates?

    Floodgates help om oorstromings vinnig te verwyder en hou die suurlaag van die grond klam.

    I'm paid along with farmer here at
  • 00:00:04
    candle candle Road we grow beef cattle
  • 00:00:07
    and we harvest grass seed and we make
  • 00:00:11
    hay and silage
  • 00:00:13
    [Music]
  • 00:00:18
    the main challenges are for us floods
  • 00:00:22
    and extended periods of wet weather
  • 00:00:25
    because the country is low so whenever
  • 00:00:28
    we have our even a small River flood we
  • 00:00:31
    we would go underwater on these paddocks
  • 00:00:34
    at Western Anna the main challenge is
  • 00:00:37
    just wet weather and trying to trying to
  • 00:00:39
    grow good grass you go heaps of grass
  • 00:00:41
    but not necessarily good grass in wet
  • 00:00:43
    weather and floods will kill everything
  • 00:00:45
    we have what we call peat moss oils old
  • 00:00:49
    old peat moss and then underneath that
  • 00:00:51
    is what's called as in sulphate soil our
  • 00:00:55
    our acid sulfate level is is reasonably
  • 00:01:00
    deep for for this type of country we
  • 00:01:04
    work on the on the top of the top
  • 00:01:05
    surface but we don't just do deep down
  • 00:01:08
    it makes it makes the general top soil
  • 00:01:11
    fairly acid so our pH is between four
  • 00:01:16
    and five if we didn't do any liming or
  • 00:01:19
    any management at all it might be even
  • 00:01:21
    below four so there's two two main
  • 00:01:25
    things we do and one is their minimum
  • 00:01:29
    tillage we try and keep out our base
  • 00:01:32
    grass our base grass established all the
  • 00:01:36
    time we don't try and spray it out or
  • 00:01:39
    cultivate it right up and to plant
  • 00:01:42
    winter crops or any other crops so we
  • 00:01:43
    tend to just leave the base grass air
  • 00:01:45
    and plant into it and we also via the
  • 00:01:51
    management of the floodgates we try and
  • 00:01:53
    keep the water table as high as as high
  • 00:01:55
    as we can and by keeping the acid
  • 00:01:58
    sulfate soil layer wet is good for us
  • 00:02:02
    and good for the environment the drying
  • 00:02:05
    the drains are probably nearly number
  • 00:02:08
    one priority on the farm because you've
  • 00:02:12
    got to get rid of that flood water so
  • 00:02:14
    that they're there to get rid of
  • 00:02:15
    floodwater
  • 00:02:15
    and but the problem is we can get rid of
  • 00:02:20
    too much soil moisture through the
  • 00:02:22
    drains so we want to get rid of that
  • 00:02:24
    that flood water as quick as we can
  • 00:02:26
    but we don't want to then dry ourselves
  • 00:02:28
    right here
  • 00:02:29
    we have a situation where you can't get
  • 00:02:33
    rid of the water off the paddocks until
  • 00:02:35
    such time as the main rivers dropped the
  • 00:02:38
    creeks dropped you can't get rid of any
  • 00:02:40
    water until they're dropped and then it
  • 00:02:43
    will flow out the floodgates so the
  • 00:02:46
    bigger the floodgate the quicker it
  • 00:02:48
    flows out our less restrictions and then
  • 00:02:53
    keeping our intermediate drains like
  • 00:02:56
    this one beside us clean and then
  • 00:02:59
    there's our paddock drains what we call
  • 00:03:02
    a spinner drain keeping them clean is
  • 00:03:04
    the is the best way of getting it off
  • 00:03:06
    off the paddocks as soon as you can we
  • 00:03:08
    have partner with Council and fisheries
  • 00:03:12
    to get some flood gates rebuilt the ones
  • 00:03:16
    in question had a really deep sill
  • 00:03:19
    height they were you know below zero i
  • 00:03:23
    HD and they were very small so even
  • 00:03:29
    though they were deep they didn't allow
  • 00:03:30
    flood waters out very quickly we came up
  • 00:03:33
    with the design of a big wide opening by
  • 00:03:37
    the sill height of plus 0.3 which allows
  • 00:03:42
    the volume to flow out really quickly
  • 00:03:44
    and the then for the environment for the
  • 00:03:49
    sake of the environment and it doesn't
  • 00:03:50
    hurt us the sill height or the drain
  • 00:03:53
    height remains 0.3 which then keeps
  • 00:03:57
    keeps the acid layer moist
  • 00:04:02
