Dalam hal ketersediaan pakan di pedesaan, jerami adalah sumber pakan yang paling banyak di jumpai, sehingga fokus kita adalah pada jerami tersebut. Jerami pada tanaman padi banyak sekali mengandung unsur nitrogen. Jerami padi merupakan sumber pupuk organik yang tersedia langsung di lahan pertanian. Mengembalikan jerami ke lahan tanaman adalah sama dengan memberikan pupuk ke dalam tanah. Dalam jerami mengandung banyak sekali unusr nitrogen karena sepertiga unsur nitrogen yang terserap tanaman padi tertinggal pada jerami. Ada berbagai macam cara dalam menangani jerami padi. Pertama, jerami langsung ditebarkan ke atas lahan kemudian dibajak sehingga jerami bercampur dengan tanah. Atau mengolahnya dahulu menjadi kompos. Dalam jerami setiap 1,5 ton atau setara dengan 1 ton gabah kering mengandung 9 kg nitrogen, 2 kg Fosfor, 25 kg Silikat, 6 kg Calsium, dan 2 kg Magnesium. Penggunaan jerami selain untuk dikembalikan ke dalam tanah sangat merugikan.
Pembakaran jerami adalah sesuatu yang tidak benar. Pembakaran jerami menyebabkan hilangnya 93% unsur nitrogen dan kalium sebesar 20%. Jika jerami ditimbun di pinggir sawah menyebabkan proses penguraian menjadi lambat. Cairan yang dikeluarkan timbunan jerami akan mematikan tanaman di sekitarnya. Timbunan jerami juga dapat menjadi sarang tikus. Dengan mengembalikan jerami akan mengembalikan unsur fosfor, besi, dan juga sulfur dan seng. Cara pengembalian jerami ke lahan adalah dengan membenamkan pada lahan pertanian satu bulan menjelang tanam. Hal ini untuk menghindari proses penguraian jerami yang mengganggu pertumbuhan tanaman. Dengan pembenaman jerami ketersediaan unsur hara dalam tanah akan meningkat. Namun ada beberapa kendala yang dihadapi dalam memproses pemendaman jerami yaitu penyebaran memerlukan tenaga, menyulitkan pengolahan dan dapat terjadi, menjadi sarang serangga.

PEMANFAATAN PUPUK ORGANIK DALAM MENGATASI KEKURANGAN PUPUK ANORGANIK
Dalam upaya meningkatkan kesuburan tanah dan mengatasi merosotnya mutu lahan sekaligus menutupi kekurangan terhadap pupuk an organik (pupuk pabrikan) pada lahan perkebunan dapat dipergunakan pupuk organik (kompos, pupuk kandang, pupuk hijau dan lan-lain). Pupuk organik dapat diperoleh dari usaha pertanian sendiri (jerami), dari usaha peternakan, limbah pabrik dan limbah kotor/rumah tangga. Penyediaan pupuk organik dapat dilakukan oleh masyarakat tani sendiri, dan ini akan menambah lapangan kerja baru disamping usaha taninya sendiri.
Pupuk organik mempunyai fungsi yang penting yaitu untuk menggemburkan lapisan tanah permukaan (tap soil) meningkatkan populasi jasad renik, mempertinggi daya serap dan daya simpan air, yang keseluruhannya dapat meningkatkan kesuburan tanah pula. Kadar mineralnya memang rendah dan masih memerlukan pelapukan terlebih dahulu sebelum dapat diserap oleh tanaman. Namun demikian menfaatnya cukup besar, sebagai contoh dapat dikemukakan sebagai berikut : 1 Hektar tanah pertanian diberi pupuk organik (kotoran ternak ayam) sebanyak 1.000 kg, berarti telah mengandung 40 kg N, 32 kg P2O5 dan 19 kg K2O. Kadar unsur hara sama dengan nilai : 2 Kw ZA, ± 2/2 Kw Tripelfoofat dan 1/3 Kw ZK. Dengan demikian maka dalam usaha mengadakan Zat Hara bagi tanah yang telah diberikan pupuk kandang seperti di atas, maka pemberian pupuk organiknya dapat dikurangi dengan perhitungan sejumlah tersebut bagi keperluan pemupukan 1 Hektar tanah.
Beberapa Pengertian Umum dari jenis Pupuk Organik :
a. Kompos adalah merupakan zat akhir suatu proses fermentasi tumpukan sampah/seresah tanaman dan adakalanya pula termasuk bangkai binatang
b. Pupuk hijau adalah tanaman atau bagian-bagian tanaman yang masih muda terutama yang termasuk famili Leguminosa, yang dibenamkan ke dalam tanah dengan maksud agar dapat meningkatkan tersedianya bahan-bahan organik dan unsure-unsur hara bagi pertumbuhan dan perkembangan tanaman yang diusahakan.
c. Pupuk kandang adalah pupuk yang berasal dari kotoran ternak.

pap cervical smear test
According to Wikipedia.org, PAP SMEAR is a screening test used in gynecology to detect premalignant and malignant (cancerous) processes in the ectocervix. This test was invented by and named after the prominent Greek doctor Georgios Papanikolaou.
You should do the PAP SMEAR test with your reliable doctor. Here is some procces of PAP SMEAR test :
The doctor inserts a speculum into the patient's vagina, to allow access to the cervix. Samples are collected from the outer opening of the cervix using some "sterile" kind of spatula and an "endocervical" brush, or (more frequently with the advent of liquid-based cytology) a plastic-fronded broom. The broom is not as good a collection device, since it is much less effective at collecting endocervical material than the spatula and brush. Then the sample are placed on a glass slide and checked for abnormalities in the laboratory.
After your doctor do the "laboratory" test, you will get your report. You may get one of the following :
1. Normal Pap smear means that all the cells in your cervix are normal and healthy. There is nothing to worry about.
2. An abnormal Pap smear (if you got this second diagnosis, you should be worry)
- Inflammation (irritation). This can be caused by an infection of the cervix, including a yeast infection, infection with the human papillomavirus (HPV) the herpes virus or many other infections.
- Abnormal cells. Usually called cervical dysplasia. This cells are not cancer cells, but may be precancerous (which means it could eventually turn into cancer).
- More serious signs of cancer. Usually affect the top layers of the cervix but don't go beyond the cervix.
- More advanced cancer.
prediksi afrika di piala dunia 2010
Piala dunia 2010 sudah semakin dekat. 11 Juni merupakan kick off pertandingan pertama dan pembukaan dalam acara tersebut. Semua Negara yang ikut serta akan berjuang dengan segenap kemampuannya. Sementara saya, hanya bisa mendukung mereka melalui postingan-postingan saja, dan juga doa.
Fair play tentu saja harus merupakan yang nomer satu diutamakan dalam suatu pertandingan. Apalagi pertandingan sepakbola. Wasit satu orang di tengah lapangan, dan dua orang di pinggir lapangan, membuat sepakbola menjadi rentan dalam hal pelanggaran. Jika kebetulan wasit tidak melihat suatu pelanggaran, dan pemain yang dilanggar tidak bisa bangun, pemain sportif harusnya membangunkan pemain yang dijatuhkan tersebut.
Piala dunia 2010 yang akan diadakan di Afrika Selatan pada Juni mendatang, merupakan ajang untuk menunjukkan diri bagi Negara-negara kecil di Afrika, bahwa mereka tidak seharusnya dipandang remeh. menjadi tuan rumah, merupakan motivasi tersendiri bagi mereka. Afrika Selatan, Nigeria, Ghana, Cameroon, Pantai Gading dan Aljazair sebagai perwakilan Afrika, tentu akan habis-habisan dalam berjuang memperebutkan Piala bergensi tersebut.
Ghana, yang walaupun baru dua kali ini ini ikut Piala Dunia(pertama tahun 2006), tidak bisa dianggap remeh. Ghana memiliki pemain-pemain dunia seperti Michael Essien (Chelsea), Samuel Koffour(Roma), Suley Ali Muntari(Inter-jika dipanggil) Stephen Appiah(fenerbachce), Boateng(AIK-masih rumit urusannya). Australia dan Jerman adalah penghalang mereka di Fase Grup D. Serbia memang bukanlah tim jelek, tapi dengan percaya diri yang kuat, Ghana kemungkinan pasti bisa memenangkan pertandingan.
Pantai Gading menghadapi lawan berat. Brazil, Portugal dan Korea Utara. Walaupun memiliki pemain kelas dunia seperti Drogba(Chelsea), Kolo Toure(Man. city), Yaya Toure(Barcelona), Arouna Koné(PSV Eindhoven), Salomon Kalou (Chelsea), Kader Keita (Galatasaray), Bakari Kone (Marseille), Emmanuel Eboue (Arsenal), tapi tentu saja tidaklah mudah menghadapi Brazil (yang notabene sudah beberapakali menjuarai Piala Dunia) dan Portugal.
Cameroon di group E, menghadapi lawan yang tidak terlalu berat. Jepang, Belanda dan Denmark. Diperkuat dengan Pemain-pemain berbakat seperti Samuel Eto’o (Inter), Alexandre Song (Arsenal), Idriss Carlos Kameni (Espanyol) yah... walaupun tidak banyak pemain berkelas, tetapi menghadapi Denmark dan Jepang pastilah tidak terlalu berat.

Did you know that as you save files and programs on your computer or browse the internet, your computer registry fills up every time?
The registry contains settings and values for the operating system, files, programs and system hardware of your computer. Basically, what goes in and out of your computer is noted in the registry. It's the catalog of your computer's activities. These entries eventually fill up and, over time, become invalid causing damage to the registry. This makes your computer run slower. Sometimes, causing it to freeze, or worse, crash.
The best way to have your PC operate in its optimum level is by having the registry always in good working order. It makes your computer run smoother and faster. This can be done by having the registry cleaned regularly. Experts recommend a registry repair every six months. Should the need arise, do it weekly. Just make sure that you back up the files and programs so that if something goes wrong, nothing will be lost.
The most efficient way of your registry fixed is by getting a registry repair software. It will free up your system of obsolete registry entries, files, or programs and speed up your PC instantly.
