Jerebu kembali lagi

Posted by mynormas on June 18, 2013

Episod jerebu akan berulang hampir setiap tahun pada musim kemarau sejak 10 tahun yang lalu. Kini ia kembali lagi.

Biasanya kita akan lebih risau tentang kesihatan kita dan manusia lain bila kita bercerita tentang jerebu ini. Masa ini juga ialah masa untuk sesetengah orang untuk mencari salah siapa yang menyebabkan jerebu.

Dengan membuat andaian anda membaca ini kerana anda mahukan cadangan untuk rumput atau mungkin tumbuhan lanskap anda, maka saya akan abaikan cadangan untuk kesihatan manusia atau siapa bakar apa dan dimana dalam artikel ini.

Tidak ada kajian khusus pernah di buat untuk menilai kesan jerebu keatas rumput. Setakat yang saya temui, terdapat kajian keatas padi, tembakau, dan Meranti.

Masalah dari jerebu

1. ialah jerebu tebal mengurangkan cahaya matahari yang akan mempengaruhi keupayaan rumput membuat makanan melalui proses fotosintesis. Fotosintesis hanya mampu berlaku bila tumbuhan mendapat cahaya matahari yang cukup.

Rumput sebelah kanan menerima kurang cahaya matahari.

Tumbuhan (rumput) yang tidak mampu membuat makanan tadi akan menggunakan tenaga simpanan yang ada di bahagian-bahagian lain seperti di batang atau akar. Bila tenaga simpanan ini habis dan masih tidak cukup sinar matahari untuk membuat fotosintesis, maka rumput ini akan mula memanjangkan lai daun nya.  Ia akan cuba untuk menambah luas permukaan daun supaya boleh memaksimakan cahaya matahari yang ada. Anda pernah lihat rumput yang tumbuh di kawasan redup? Ia akan menjadi lebih panjang dari biasa; panjang tapi kurus.

2. di dalam jerebu tersebut terkandung partikel-partikel seni yang akhirnya akan mendap ke atas permukaan rumput. Kalau seni yang saya maksudkan ialah seni budaya tidaklah ia menjadi masalah. Tapi partikel2 disini ialah oksida dan juga ‘heavy metal’ seperti Plumbum dan Sulfur. Ia akan melekat pada permukaan daun atau tanah. Jika dibiarkan unsur2 ini akan terkumpul dan akhirnya memberi kesan ke atas kimia tanah atau rumput tadi.

3. ‘Hujan asid’ iaitu kombinasi hujan dan pencemaran udara. Tidaklah bermaksud akan berlaku hujan yang boleh melubangkan baju anda; tapi tahap keasidan air yang turun itu ialah lebih dari hujan biasa. Ini berlaku walaupun tiada jerebu. Anda juga bertanggungjawab untuk fenomena ini bila anda membuat apa2 pembakaran, termasuk enjin kereta anda. Hujan asid ini akan – sedikit sebanyak – meninggalkan kesan keasidan pada tanah juga.

Penyelesaiannya.

1. Tinggikan ketinggian potongan.

JANGAN tidak potong! Teruskan memotong seperti biasa tetapi tinggikan ketinggian pemotongan. Jika anda orang yang potong rumput menggunakan ‘brush-cutter’: susah. Susah kerana ketinggian pemotongan bergantung kepada agak-agak dan bukan ukuran. Beri arahan spesifik dan awasi kerja contractor.

Saya mencadangkan anda perhatikan rumput anda, jika anda dapati ia mula memanjang (anda mula memotong lebih banyak batang dari daun, atau anda dapati lebih banyak ‘sampah’ di kutip oleh pemotong anda dari biasa, atau sekadar dari pemerhatian) maka anda  ketinggian baru ialah pada ketinggian yang memberi sampah yang sama banyak seperti dahulu. Tak tahu nak agak? Mulakan dengan tambah ketinggian sebanyak 10%.

Terutamanya green di padang golf yang dipotong pada ketinggian kurang dari 5mm.

2. Siram

Anda juga patut menambah kekerapan penyiraman kerana ini akan membantu ‘membasuh’ permukaan lai daun dan membawa partikel2 seni tadi  ke dalam tanah atau keluar dari kawasan rumput. Awas tidak menyebabkan lecak. Elakkan juga dari menyiram di waktu lewat petang. Tanah akan basah hingga ke malam. Ini boleh membawa kepada penyakit dan lumut.

Siram awal pagi atau tengahari. Jangan sampai air bertakung.

3. Bantu tanah anda.

Anda juga boleh membantu perjalanan air ke dalam tanah dengan hollow tining, slicing, spiking atau semata-mata mencucuk-cucuk tanah supaya air boleh turun ke bawah dengan cepat. Sebaiknya buat selalu tapi sedikit. Lihat artikel tentang pengudaraan di halaman rumah atau di padang bola.

Selamat mencuba!

Cutting grass without injuring others

Posted by mynormas on May 31, 2013

Jika alasan anda ialah kecerunan; cuba cari mesin "hover mower"

Jika alasan anda ialah kecerunan; cuba cari mesin “hover mower”

The recent case of a child injured by flying debris gave me the impetus to write this letter. I see a lot of people  – from local authorities to homeowners to football associations  – planting grass but the most common method used to cut the grass is by using the backpack mower called the  ‘brush-cutter’; ‘bush-cutter’; ‘whipper-snapper’ or even the ‘helicopter’.

This machine is favoured because it is cheap, portable, simple to use and require almost no maintenance. When the blades are changed to nylon strings heads, there is one added advantage: there is no need for sharpening.

A few observations about this “brush-cutter”:

  1. The business end of this machine consists of naked rotating blades or nylon strings.  These blades/strings would turn at high speed to cut the grass by impact. Needless to say the same impact would fling stones, pebbles, sand particles and other debris on the ground at high speed towards the operator and those around him or her. Its made worse when the operator rests the strings on the ground.

  2. Due to the weight and vibration of this machine only the tough and hardy are willing to operate it for long periods. Hence we see this work being ‘monopolized’ by foreign employees. If we really want to reduce our dependency on foreign workers, lets reduce our dependency on this machine first, at least in this context.
  3. This also has the effect of keeping turfgrass and landscape maintenance in the realm of labourers or part-time odd-job workers. This would negate the efforts of the efforts of the Youth and Sports Ministry – among others – that for the past few years has been working on a syllabus to train youths in landscape, stadium and golf course maintenance with the intention of turning this into a career.
  4. In the hands of the untrained – or the tired – operator, the tendency is to rest the blades or the strings on the grass.  This would cause a very low height of cut (think: ground height) Grass needs leaf to do photosynthesis to produce food and cutting at low heights just removes too much leaves. There is a “rule of thumb” of not cutting more than one-third of the grass when mowing. No way can the “brush cutter” maintain a consistent mowing height of one-third of anything.

I call on everyone who has authority over grass cutting (and that includes homeowners) to stop or limit the use of these machines. Homeowners should consider buying their own electric grass mowers (available in most hypermarkets). Local authorities, building and golf course owners should consider renovating their turfed areas so that its more accessible to ride-on mowers. Architects too must design turfed areas with ride-on machines in mind or look at  alternatives other than grass for example ground-covers, wild flowers, weeping lovegrass, pebbles or even artificial turf.

Homeowners should mow their grasses more often than the occasional time when the grass cutter knocks on your gate when he sees your grass long. The grass Malaysians call Carpet grass grows very quickly and should be mown as often as at least once a week. Petrol engined mowers are high maintenance so do consider an electric or ground-driven mowers.

Many land owners, football associations, golf courses and even homeowners dream of striping their grass. This can never be achieved with “brush cutters”. And no; contrary to popular belief, you don’t need golf course priced machinery to stripe your grass, any mower with a heavy roller behind it (and this can be modified with a metal or GI pipe) will stripe a field with enough discipline on the part of the operator.

With a brush cutter? All you need is a sneezy operator and you can kiss your beloved grass goodbye.

These poor grass has been mown with a brush cutter - maybe the operator has the flu.

IM4U. MMO. GCM. ASAP.

Posted by mynormas on March 8, 2013

IM4U has been the logo for volunteering lately & coincidentally, volunteers are wanted for the Maybank Malaysian Open in golf course maintenance as soon as possible.

Preparing greens 2011

Preparing greens 2011

Mohd Nizam Othman (KLGCC’s Supt and lets just call him Nizam) is pretty well prepared for the tournament himself. A veteran of numerous high profile tournaments, he and his team have things under control. But having volunteered in a similar type of event in Singapore just recently, he would love to see the same spirit being practiced here in Malaysia, and at the same time; share the experience and excitement of being part of history.

As for the volunteers, they will get to experience and learn how a golf course is prepared for a major tournament and the pressure the golf course maintenance department (especially the senior staff) is under. Nizam will be preparing a certificate for the volunteers too, only for those who turned up when and where they are supposed to of course, which will give you the right to brag that you have worked in a course to prepare for a major tournament (which is where the part about the ‘experience and excitement of being part of history’ comes in).

This being one of the premier golf tournaments in the country if not in the region; in a golf course that is considered to be one of the best in the country if not in the region; with standards that is judged to be one of the highest in the country if not in the region, Nizam would like to extend the invite only to those that fulfill certain criterias (refer below) to others, he will extend his ‘thank you for your support’ handshake and please leave your number because he might still call you.

By the way, and this is from me and not from Nizam; if your sole purpose to volunteer is to get free entrance; please reconsider volunteering.

Nizam says that he will provide breakfast, lunch and high-tea for the volunteers.

Algae on golf greens

Posted by mynormas on January 2, 2013

In the context of Malaysian weather where heavy and frequent rain is the norm, plus with poorly or compacted greens, shade from surrounding trees; algae is quite common.I found this slideshare article that is very informative and thought that I should share it.

Be advised that even though the title is about golf greens, much of the info are also applicable to other parts of turfed areas (yes your lawn too madam)

If you think most of the slides’ contents are too ‘academic’ jump straight to slide number 53, though you might be searching backwards for background info but at least you know what you are looking for is what you need to know.

This is the first time I am doing this so I hope this turns out alright…

Zoysia green.

Posted by mynormas on September 3, 2012

image

As I said, its the first time I used this app. Just tilt your head to the right to see the image.

My first ever Zoysia green (and my first ever posting with this app). It was an unused and un maintained roundabout behind the club kitchen and the cooks were dumping their old equipment on it! One pro tournament at the club wanted a practice green and that was the only option available. They gave me two weeks notice to get it done. Managed to do it just in time and maintained it as a green ever since. It may be the ‘wrong grass’ but it sure is easier to maintain than the greens here that have many different types of grasses.

Turf Consultancy Sdn Bhd

Posted by mynormas on July 21, 2012

After a long period of gestation, I’d like to finally announce the formation of my company that specializes in consultancy, training, maintenance and supply of turfgrasses. Yes I do renovations and reconstruction too. As for landscaping, I will be doing joint-ventures with other companies. I will announce that at a later date.

mynormas’ new company.

The name of the company? Turf Consultancy Sdn. Bhd. I don’t have the mission statement, vision or even a tagline yet. Or maybe I won’t ever have one. I know what I what the company is for; it is to leverage on my and my peers knowledge and ability to improve turfgrass maintenance and management in Malaysia.

So for  stadiums, fields and parks that are looking to improve the quality of their grass,  call Normas at 0I2-5II 3353 or email mynormas@consultant.com.

Golf courses that have problems with their greens, or having drainage problems can call me too.

Being a former GM means I can also help out with the business or management side too.

I also specialize in trainings for turfgrass workers; teaching them the basics so that they know their stuff. For senior or long-term staff, I do machinery operation basic training and especially important for golf courses: I do training for chemical and fertilizer application. Hands-on. With a small class.

Well, I’ll do the advertisements and stuff at a later date. This is just the announcement of the company’s name for now (taking advantage of the first day of the month of Ramadhan).

Not forgetting to wish everyone a blessed Ramadhan.

Jerebu (haze) & rumput

Posted by mynormas on June 19, 2012

Episod jerebu akan berulang hampir setiap tahun pada musim kemarau sejak 10 tahun yang lalu. Kini ia kembali lagi.

Gambar jerebu di sebuah padang golf

Biasanya kita akan lebih risau tentang kesihatan kita dan manusia lain bila kita bercerita tentang jerebu ini. Masa ini juga ialah masa untuk sesetengah orang untuk mencari salah siapa yang menyebabkan jerebu.

Dengan membuat andaian anda membaca ini kerana anda mahukan cadangan untuk rumput atau mungkin tumbuhan lanskap anda, maka saya akan abaikan cadangan untuk kesihatan manusia atau siapa bakar apa dan dimana dalam artikel ini.

Tidak ada kajian khusus pernah di buat untuk menilai kesan jerebu keatas rumput. Setakat yang saya temui, terdapat kajian keatas padi, tembakau, dan Meranti.

Dua perkara utama pada jerebu akan memberi kesan pada rumput:

Pertamaialah jerebu tebal mengurangkan cahaya matahari yang akan mempengaruhi keupayaan rumput membuat makanan melalui proses fotosintesis. Fotosintesis hanya mampu berlaku bila tumbuhan mendapat cahaya matahari yang cukup.

Rumput sebelah kanan menerima kurang cahaya matahari.

Tumbuhan (rumput) yang tidak mampu membuat makanan tadi akan menggunakan tenaga simpanan yang ada di bahagian-bahagian lain seperti di batang atau akar. Bila tenaga simpanan ini habis dan masih tidak cukup sinar matahari untuk membuat fotosintesis, maka rumput ini akan mula memanjangkan lai daun nya.  Ia akan cuba untuk menambah luas permukaan daun supaya boleh memaksimakan cahaya matahari yang ada. Anda pernah lihat rumput yang tumbuh di kawasan redup? Ia akan menjadi lebih panjang dari biasa; panjang tapi kurus.

Kedua, di dalam jerebu tersebut terkandung partikel-partikel seni yang akhirnya akan mendap ke atas permukaan rumput. Kalau seni yang saya maksudkan ialah seni budaya tidaklah ia menjadi masalah. Tapi partikel2 disini ialah oksida dan juga ‘heavy metal’ seperti Plumbum dan Sulfur. Ia akan melekat pada permukaan daun atau tanah. Jika dibiarkan unsur2 ini akan terkumpul dan akhirnya memberi kesan ke atas kimia tanah atau rumput tadi.

Satu lagi kemungkinan ialah ‘hujan asid’ iaitu kombinasi hujan dan pencemaran udara. Tidaklah bermaksud akan berlaku hujan yang boleh melubangkan baju anda; tapi tahap keasidan air yang turun itu ialah lebih dari hujan biasa. Ini berlaku walaupun tiada jerebu. Anda juga bertanggungjawab untuk fenomena ini bila anda membuat apa2 pembakaran, termasuk enjin kereta anda. Hujan asid ini akan – sedikit sebanyak – meninggalkan kesan keasidan pada tanah juga.

Penyelesaiannya? Saya hanya mencadangkan anda perhatikan rumput anda, jika anda dapati ia mula memanjang (anda mula memotong lebih banyak batang dari daun, atau anda dapati lebih banyak ‘sampah’ di kutip oleh pemotong anda dari biasa, atau sekadar dari pemerhatian) maka anda patut menaikkan ketinggian potongan. Terutamanya green di padang golf.

Anda juga patut menambah kekerapan penyiraman kerana ini akan membantu ‘membasuh’ permukaan lai daun dan membawa partikel2 seni tadi  ke dalam tanah. Anda juga boleh membantu perjalanan air ke dalam tanah dengan hollow tining, slicing, spiking atau semata-mata mencucuk-cucuk tanah supaya air boleh turun ke bawah dengan cepat.

Lagi?  Doa banyak-banyak untuk mintak hujan atau salahkan orang sebelah yang tengah bakar sampah tu…

Campus on the Greens

Posted by mynormas on June 5, 2012

I received an email from a Course Superintendent friend in Brunei a couple of months back. In conjunction with a major conference that will be held in Brunei at the time, Nigel (the said friend) wants to hold a separate event that is exclusive for people who are / interested in managing turf. I suppose it is about the sharing of ideas among peers. It sounds great and I fully support it! I think fellow Superintendents and Groundspeople from the region should participate. I am reproducing Nigel’s email verbatim here.

Feel free to contact him with your ideas/suggestions. Remember: “There are no silly ideas, only silly people who don’t give ideas” (does that work? I came up with that at the spur of the moment).

Dear Industry Colleagues,

For those of you that do not know me, my name is Nigel Taylor and I am the Golf Course and Landscape Superintendent here at The Empire Hotel & Country Club.  Later this year we are lucky enough to be hosting a huge week of golf, starting with the Asia Pacific Golf Summit and concluding with the Royal Trophy golf tournament where Asia will battle it out against Europe.

I am writing to you today to talk about the Asia Pacific Golf Summits new addition – The Campus on the Greens.  This year, for the first time, the Superintendents stream of the Summit will be a much more hands on experience.  It will be an experience that takes you out of the lecture hall and puts you standing on actual golf course, one that will be conditioned ready for a major tournament – The Royal Trophy.

In creating the field sessions I am also attempting another first and that is to ask for input from Superintendents on the content they would most like to see presented at the Campus on the Greens.  Basically surveying the region to ensure we can present the topics that most resonate with your day to day operational problems and needs.  Obviously we won’t be able to present every ones suggestions, to some degree this will be dictated by the availability of speakers, but we will endeavour to present a very well rounded range of topics that have been suggested by you and your peers.

I hope you can take the time to have a think about what yourself and your fellow grass practitioners’ would like to have presented and I look forward to hearing back from you soon.

P.S. for those of you who attend the Summit we will also be implementing a volunteer program to assist with the preparation of the golf course for the Royal Trophy.  More details on this will follow soon, but in short you will have a chance to go inside the ropes before, during and after each days play.

Thanks and I look forward to hearing from you soon!

–

Regards,

Nigel Taylor

Menyiram waktu panas

Posted by mynormas on June 4, 2012

Elakkan dari menyiram air mengikut jadual tertentu. Kita sebagai manusia secara amnya tidak minum air mengikut jadual, tetapi mengikkut kehausan jadi kita menyiram rumput pun sebaiknya mengikut keperluan rumput.  Apa yang saya maksudkan di sini ialah menyiram rumput setiap hari pukul 8 pagi atau pukul 6 petang. Kalau tengah hujan pun kita siram jugak kerana nak ikut jadual.

Siram ikut keperluan.  Jika tanah pada kedalaman satu inci di bawah masih basah; tak perlu siram. Jika ia kering; boleh (bukan mesti) siram.

Ini bermakna ada hari kita siram satu hari sekali, ada hari dua kali dan ada hari tiga kali sehari. Dan kadang-kadang: tak siram berhari-hari.

Tips;

  • untuk kawasan yang redup; elakkan siram di waktu petang. Kawasan yang basah di waktu petang akan menggalakkan rumput.
  • amalkan siram di awal pagi; air akan kekal di dalam tanah di waktu rumput memerlukannya sewaktu terik nanti.
  • Bila siram, siram hingga di anggarkan air akan tembus beberrapa inci ke dalam tanah. Ini akan menggalakkan akar tumbuh panjang mencari air.
  • Menyiram terlalu kerap (untuk kawasan rumput yang dah matang) akan menyebabkan rumput manja dan terlalu mengharapkan air yang di siram dengan tidak berusaha mencari air sendiri.
  • Terik matahari boleh membakar akar rerambut yang berada di berhampiran permukaan tanah.
  • Syringe ialah suatu teknik menyiram yang berfungsi menyejukkan permukaan rumput (dan bukan ‘memberi air’).
  • Rumput yang ditanam di atas pasir lebih memerlukan air di siram daripada rumput yang di tanam di atas tanah.
  • Tidak semua tempat memerlukan jumlah air yang sama. Ada tempat perlu di siram lebih dari tempat yang lain.
  • Jangan siram hingga mencapai tahap tepu tanah; siram dan biar sekejap sebelum siram lagi.
  • Jangan siram di kawasan lereng sehingga air mengalir ke bawah; siram dan biar sekejap sebelum siram lagi.
  • Umumnya; siram jarang-jarang tapi dalam-dalam adalah prinsip menyiram rumput di kawasan matang.
  • Menyejukkan rumput di waktu terik panas akan menyelamatkan akar rumput yang dekat dengan permukaan dan mengurangkan kadar kehilangan air.
  • Jika anda mampu menyiram hanya sekali dalam sehari; siram pagi. Bukan petang; dah terlambat dan akan menyebabkan lumut dan penyakit.
  • Jika anda mengalami localized dry spot (LDS) gunakan ‘wetting agent’ ataupun tebuk tempat tersebut supaya air boleh tembus. LDS biasanya di sebabkan oleh tanah hydrophobic dan air hanya di permukaan.

Selamat mencuba!
