Gelek Padang.

Gambar Hiasan Semata-mata.

Pernahkah anda di beritahu bahawa padang/green anda keras? Apa? Tak pernah? Okay; cuba soalan soalan ini pula: Pernahkah

  1. anda lihat air bertakung di atas permukaan padang anda selepas hujan lebat sedangkan anda tahu anda ada longkang subtanah (subsoil drain) di bawah padang?
  2. anda di beritahu bahawa jika bola tinggi melantun di atas padang atau green anda, ia sukar di kawal atau di ramal?
  3. anda di minta untuk siram padang pada separuh masa atau sebelum tournament bermula?
  4. pemain mengadu sakit lutut/pinggang/kepala lepas main di padang anda?

Anda tahu kenapa? Kerana anda suka gelek, giling, roll, kompak padang anda dengan keterlaluan; samada menggunakan roller yang berat atau pun dengan kekerapan yang tinggi.

Terlalu ramai penjaga/pengurus padang percaya bahawa untuk MERATAKAN padang mereka perlu gelek. Ingat; kita gelek untuk mendapatkan permukaan yang baik (smoothen) bukan untuk meratakan (flatten). Jika anda perlu gelek untuk mendapatkan permukaan yang rata; anda mempunyai masalah lama yang perlu diselesaikan dan mencipta masalah baru di masa akan datang.

Pada posting lepas saya dah bincang tentang tiga isu yang akan timbul jika anda gelek terlalu kerap atau menggunakan penggelek terlalu berat:

  1. Mengwujudkan mampatan
  2. menjadikan kawasan keras tinggi dan kawasan lembut rendah
  3. Ketagihan.

Ada masalah ke empat yang akan timbul ekoran dari semua di atas; gelekan yang keterlaluan akan menjadikan padang anda keras. Terutamanya jika anda menggunakan ‘topsoil’ atau tanah liat atau ‘native soil’ (green padang golf) sebagai media tanaman.

“Ok lah pakar” cabar anda kepada saya “kalau kau pandai sangat, macamana kami nak buat kalau padang kami tidak rata?”

Lakukan hias atas (orang dulu kata topdressing) iaitu menggunakan lapisan pasir nipis untuk mengisi kawasan lembah dan lekuk. Kadang kadang lekuk itu dalam maka kerja hias atas perlu di lakukan berkali kali.

Atau, kalau lekuk itu betul betul dalam: kambus saja lah.

Begitu juga kalau padang anda berbonjol dan ada bonjol tinggi yang hampir di katakan lucah oleh orang otak kuning; ambil cangkul, korek keliling nya dan keluarkan rumput bersama tanah setebal 4 hingga 6 inci, buang tanah di bawahnya sedalam yang perlu kemudian tampal balik rumput dan tanah tebal tadi. Insya Allah rumput tak mati kalau anda korek tebal (bukan korek rumput sahaja).

Di green padang golf pula, terdapat pelbagai cara lain untuk mendapatkan green yang laju selain dari ‘roll’ atau turunkan pisau. Cuba groom atau hias atas nipis atau dethatching. Saya pernah tarik dragmat (karpet besi) atas green seminggu dua kali untuk melajukan green. Satu langkah yang banyak superintendan tidak buat ialah mengukur kelajuan semua 18 green, mengenali yang mana paling perlahan dan fokus pada green green itu sahaja setiap hujung minggu. Saya berpendapat terlalu banyak gelek adalah sangat tidak sihat sehinggakan saya lebih rela membiarkan klien saya percaya kepada baja potassium silicate untuk melajukan green dari membiarkan mereka gelek. Sebenarnya tiada bukti potassium silicate boleh melajukan green tetapi setakat ini, tiada kesan sampingan maka ia lebih baik dari menggelek.

Kenapa saya timbulkan isu ini lagi? Kerana masih lagi ada orang yang kata mereka nak gelek untuk meratakan padang. Saya kata “Nanti keras padang”. Mereka kata “Terpaksa. Tiada jalan lain”

Keras kepala.

Terlalu banyak gelek adalah sangat tidak sihat melainkan anda adalah Mas Idayu, Ratu Gelek Malaysia.

Padang Bola

Posted by mynormas on December 14, 2016

Mulai tahun 2016, saya mula melibatkan diri lebih kepada penjagaan padang bola. Jika anda sangka penjagaan padang bola hanyalah tentang memotong rumput – anda silap – tetapi anda mempunyai ramai teman seangkatan fikiran. Itulah realiti penjagaan padang bola di Malaysia, samada padang bola sekolah ataupun milik persatuan bolasepak. Cuma di tambah dengan kebolehan menggelek padang dengan penggelek besar untuk meratakan padang yang, sebenarnya, boleh merosakkan padang. Malahan, kerja memotong pun dilakukan dengan kekerapan yang silap kerana banyak padang yang saya temui memotong rumput satu kali sebulan malah saya pernah di beritahu tentang padang yang memotong setengah padang sebulan (ertinya mereka memotong rumput satu kali dua bulan).

Selain dari memotong, penjagaan padang juga seharusnya merangkumi kerja kerja amalan kultura seperti pengudaraan padang, pemotongan menegak, hias-atas, aplikasi nutrisi (pembajaan) selain dari kerja pembaikan kerosakan, pembuangan sampah dan sebagainya.

Kerja hollow-tine membantu udara dan air masuk ke dalam tanah dan memberi ruang kepada serangga, kulat, nematod, bakteria yang berfungsi sebagai suatu ekologi tanah yang membantu penghidupan rumput. Jika tanah anda padat, mereka akan mati, dan rumput anda akan mati.

Jika anda mencari kontraktor profesional berpengalaman yang mampu membuat kerja hollow-tine, dethatch, membaja, topdress dan memberi nasihat kepada anda tentang penjagaan padang, hubungi saya di mynormas ATconsultant.com dengan menggantikan AT dengan @.

Hias-atas atau topdress ialah kerja-kerja menabur selapis pasir secara raa ke atas padang kemudian menggunakan suatu alat khusus, menarik/menolak pasir supaya turun dari permukaan tinggi ke kawasan rendah. Kawasan rendah yang di maksudkan ialah contohnya bekas kasut atau tendangan pemain, bekas tayar mesin ataupun kesan dari ‘sliding tackle’. Semua ini tidak kelihatan kerana rumput akan di potong sama tinggi sedangkan tanah tinggi rendah.

Weeds

Posted by mynormas on November 18, 2011

Most people don’t pay too much attention to those grasses that don’t seem to belong to the rest of the grasses surrounding them. The reason being those grasses doesn’t usually impose themselves on people.  Other than aesthetics that is. Even if the grasses seem – at first glance – to be similar, there is that slight difference in colour, texture or something that makes people dislike.

What are these grasses?  How did they come to be where they are?  Why are they left alone?  How do we get rid of them? Should we get rid of them?  What are they called?

They are called – other than the colourful names some people use to describe them – weeds.

A weed is defined as a plant that grows where it is not wanted. So, because of the  definition, a rare black orchid growing in the middle of a fairway would be attacked by changkul-wielding workers before we can finish saying “Rare black orchid is a weed?” Similarly, a banana plant three feet from the pin on a green is a weed, never mind the nutritional qualities of a banana.

These weeds are called ‘sedges’ and they love wet areas.

Weeds are transplanted in many ways. Assuming a particular golf course or field or taman is constructed, planted and maintained to perfection (this would presumably be on Planet Krypton), weeds can be transported by wind, animals, water, humans or machinery.  Sometimes it could also inadvertently be transported by the maintenance staff when they borrow a machine or equipment from another place. This does not only necessarily mean from one golf course to another, but also from one hole to another in the same golf course.

Why Weeds Happen – During Construction.

You would think that no one would plant a weed on their field. No one intentionally would; but sometimes that’s what happens when the owner/manager purchases new planting material like seeds, stolons or sods. To cut cost the planting material might be purchased from the nursery that gave them the lowest quote.  Chances are that these nurseries may not apply the best management practices to ensure weed-free materials. How else can they quote so cheap?

Are they planting pure grass stolons are are there weeds seeds mixed in? Did you check? By now, can anyone check?

What some nurseries do is to regularly mow their plots to keep most weeds down to the same height as the surrounding grasses.  And when they smell a potential sale, they do a hurried manual weeding job before the buyer’s representative arrives for an inspection visit.

For golf courses, this may be the same scenario if we get our planting material – especially in big quantities – from the award-winning golf course that our boss has friendly relations with.  You don’t think they will rip off their best greens and fairways to give us the stolons do you?  You might as well ask for their right arm.  We may get away with getting the stolons during their renovation works like hollow-tining or verti-cutting.  Just be aware that it’s almost impossible to be weed free on all 18 holes (we are not on Planet Krypton) and a verti-cutter machine going on a weed the size of the palm of your hand will create hundreds of tiny baby weeds waiting to sprout on the golf course.

Actually, the story can begin long before the first planting material is purchased.  It starts when the soil is being prepared for planting.  When the earth was pushed to make way for a golf course, or when the soil is expertly shaped waiting for the planting of the seeds or stolons of the chosen species of grass, it contains planting material of many different species of plants. Each and every viable seed is a potential weed waiting for the right time to sprout.

There are, of course ways to treat the soil – from simply turning the soil over to expose the seeds to sunlight to the complex way of covering it with plastic sheets and injecting it with chemicals – which, by the way, should only be done by licensed applicators.

If you are planting your own field/lawn visit the nursery, ask the supplier to show you which part of nursery they want to harvest for you, then on planting day, insist that they do NOT harvest before you or your rep being there. You don’t want them to show you one part of the nursery then harvest from another part to plant in your field/lawn.

Why Weeds Happen – During Maintenance

As so often is the case, an ill-advised attempt at cost reduction is usually the root cause of many evils when aesthetics is one of the performance indicators.  You will hear me repeat this line often: nothing is free in this world; we will pay for it one way or another. Maintain the grass poorly, it will not grow well and, in this instance, will provide an opportunity for weeds to move in.  We will eventually spend money to remove the weeds from the golf course. This paragraph will still hold true when I write about disease or pests in the golf course in future articles.

Poor maintenance can cause weeds, this drainage line was left open. So weed came in.

In short; do not expect the maintenance staff to cut costs to the point the grass’ health suffers.  Starve it if you must. But make it suffer it you mustn’t.

In the quest for being environmentally friendly, some golf courses used organic fertilizers to feed their grasses. Now, these organic fertilizers are good food for the soil as much as it is good for the grass, but if we calculate on the amount of nutrient it can deliver, it may prove to be quite expensive. Fertilizer made from organic products that are not properly treated may contain weed seeds. Chicken dung and other animal waste or even products made from plant waste may be contaminated at source or during the process to turn it into plant food.

There is a legend of how a Superintendent of a golf course placed an order of several tons of processed chicken dung fertilizer.  The purchasing clerk, who with good intentions, believes that all chicken dung are alike proceeded to buy the cheapest one available.  The cost of weeding the golf course in the months afterward probably is much higher than the savings on the purchase of the fertilizer.

Weeds can occur in places where there is compaction, such as high-traffic area. Or wet/damp areas. Or dry sandy areas. Different weeds will thrive and specialise in different areas.

The Cure

So now you know where weeds has its roots (pun intended) and you want to roll up your sleeves and ask your maintenance staff on how you can help fight this scourge on the grass field.

How does the staff take care of the weeds?  He/she has quite a few things in his arsenal. First and foremost are the mechanical means, which includes sending an army of labourers digging up the weeds with small screwdriver-like implements. It works to a certain extent; at the very least it controls the population of the weeds. More often than not, the staff may miss out the small ones or neglect to dig up the roots which may sprout again. But if you have the budget, this would be one of the best ways to get rid of them.

Another option would be to use chemicals. And there are plenty of chemicals; ranging from those to be used before the weed seeds germinate – called pre-emergent – to those designed for use on living weeds – called post emergent. Most weedicides or herbicides, for this is the category the chemicals used to kill weeds is called, belong to the post-emergent type.

More often than not, the staff will choose a ‘selective’ herbicide; these are the chemicals that may spare the original grass and kill a certain type or family of weeds. The danger is that if the wrong mixture or rate is used, it may kill the original grass itself.  You might also note that even if it doesn’t kill the original grass, there may be a slight discoloration that will be visible for a week or two.  The opposite of a ‘selective’ herbicide will be a ‘kill-all’ herbicide, for want of a better word.

The staff can also choose to use either a contact herbicide that will kill the weeds it is supposed to on contact or he can choose to use a systemic one, which will be absorbed through the plant and start to kill from within. If he chooses a contact, he may need to use a reliable sprayer so that full coverage can be effected. Otherwise, the herbicide may only kill parts of a grass instead of all of it.

Please be reminded that all the above information is only a fraction of a branch of knowledge used by maintenance staff.  For more information regarding herbicides in particular or weeds in general; get in touch with me.

Lumut di rumput

Posted by mynormas on November 17, 2011

Lumut atau algae bukan suatu penyakit. Ia adalah simptom kepada satu masalah: masalah kelembapan yang keterlaluan. Kadang-kadang kelembapan di sebabkan oleh:

Lumut bermula di celah-celah rumput

  1. air yang bertakung dan lambat kering,
  2. kawasan redup yang kurang matahari
  3. tanah yang terlalu padat dan tidak mengalirkan air ke bawah.
  4. Terlalu banyak air dari siraman atau hujan.

Rumput akan menjadi semakin jarang kerana akar rumput memerlukan udara untuk bernafas dan jika tanah itu lembab terlalu lama maka akar rumput akan reput atau mati. Algae akan tumbuh kerana algae sesuai atau suka dengan kawasan lembab.

Algae adalah tumbuhan mudah (simple plant) tetapi ia masih memerlukan cahaya matahari untuk membuat makanan.

Jadi untuk mengurangkan algae, kita boleh buat dua perkara; kurangkan kelembapan dan atau menafikan cahaya matahari dari kena kepada algae tersebut. Ada juga pendapat yang mengatakan bahawa algae suka kepada tanah yang sedikit berasid, tetapi dari pengalaman, saya pernah juga jumpa algae di green yang di uji sebagai tanah pH neutral dan green padang golf yang baru di tabur dengan kapur CaCo3.

Menebuk lubang lebih kurang 2 inci supaya air mengalir ke bawah.

Bagaimanapun cadangan saya ialah dengan menebuk lubang kecil di kawasan yang berlumut supaya air boleh mengalir kebawah; kurangkan kelembapan dengan mengurangkan dahan-dahan yang membayangi tanah, melakukan topdressing dengan pasir supaya ‘melemaskan’ algae yang lebih rendah dari rumput dan mengurangkan pengairan serta menambah saliran.

Saya pernah mencakar lumut supaya rumput dapat tumbuh tapi apa yang saya dapati ialah ia akan tumbuh semula selepas beberapa hari jika masalah kelembapan tidak di atasi.

Satu caveat: menebuk lubang di permukaan supaya air mengalir ke bawah hanya berkesan jika bahagian bawah tanah mempunyai saliran yang berkesan (contohnya mempunyai kandungan pasir yang tinggi), tetapi jika bahagian bawah permukaan juga adalah tanah liat atau tanah yang memegang air, maka mungkin terpaksa di korek dalam lagi, menggunakan besi panjang ataupun penggali lubang seperti auger.

Topdress mempunyai 2 kegunaan: 1 ialah menutup lumut dari menerima cahaya matahari dan 2 ialah membantu akar rumput tumbuh di tempat kosong. Tetapi, seperti dalam gambar ini; topdressing sewaktu musim hujan adalah kerja mencabar.

Jika permukaan sahaja yang bermasalah (selalunya kerana di lanyak atau di lenyek) maka kadang-kadang menggunakan sekadar parang tumpul dan mengguris permukaan supaya air tembus algae dan masuk ke bawah.

Selamat mencuba!

How much sand to topdress?

Posted by mynormas on February 27, 2011

I’ve heard it both ways. I’ve seen people topdress so much that the grass cannot be seen and I’ve seen people topdress so little you could barely see the sand.the 'layering effect'

My opinion is somewhere in the middle for normal routine topdressing and topdressing after aeration. If I were to topdress prior to a major tournament, then I would get my spinner out for topdressing.

Heavy topdressing has the potential to create a layering effect

Topdress yang terlalu tebal boleh menyebabkan ‘layering’ atau lapisan iaitu pasir yang tebal menjadi satu lapisan baru dan membenam mat atau thatch ke bawah. Lebih merbahaya lagi jika pasir yang digunakan mempunyai saiz ketulan yang lebih halus dari tanah sekarang.

What is more important is to make the topdressing even.

Apa yang lebih penting ialah membuat topdressing rata.

too heavy

heavy topdress

light topdress
