Do the following tasks properly.Read the text and answer the questions that follow. Growing crop plants need several elements to make it stay alive. The most important elements for plantation are hydrogen, carbon, oxygen, phosphorus, nitrogen, sulfur, potassium, calcium, and magnesium. Crop plants obtain carbon and hydrogen dioxide from the atmosphere. While the other nutrients are taken up from the soiI. If the soil's nutrient is not enough, the crop plants will not maximally grow. It can affect the amount of production. So to avoid that case, farmers need to give additional nutrients or doing the soil treatment. Overall chemical analysis indicates that the total supply of nutrients in the soil is usually higher in comparison with the requirement of crop plants. Much of this potential supply bound tightly in forms that are not released to crops fast enough to give satisfactory growth. This will make farmers interested in measuring the available nutrient supply as contrasted to the total quantities. Why do farmers prefer considering the only available nutrients to the total quantities of nutrient found in soil?

Pembahasan
Soal menyakan alasan mengapa para petani lebih mempertimbangkan unsur hara yang tersedia daripada jumlah total unsur hara yang ditemukan di tanah. Jawaban dari pertanyaan ini dapat dicari pada paragraf ketiga. Paragraf ketiga menerangkan bahwa jumlah total unsur hara yang terdapat di dalam tanah sangat melimpah, jumlahnya pun sampai melebihi kebutuhan tanaman akan unsur hara itu sendiri. Namun, kebanyakan dari unsur hara potensialtersebut tidak dilepaskan dengan cepat untuk membantu pertumbuhan tanaman. Oleh karena itu, para petani lebih mempertimbangkan ketersediaan unsur hara yang ada daripada jumlah total unsur hara yang ada pada tanah. Dari penjelasan di atas, jawaban yang tepat adalah " Becausethe crop plants only need a few total supply of required nutrients to grow."
Soal menyakan alasan mengapa para petani lebih mempertimbangkan unsur hara yang tersedia daripada jumlah total unsur hara yang ditemukan di tanah.
Jawaban dari pertanyaan ini dapat dicari pada paragraf ketiga.
Paragraf ketiga menerangkan bahwa jumlah total unsur hara yang terdapat di dalam tanah sangat melimpah, jumlahnya pun sampai melebihi kebutuhan tanaman akan unsur hara itu sendiri. Namun, kebanyakan dari unsur hara potensial tersebut tidak dilepaskan dengan cepat untuk membantu pertumbuhan tanaman. Oleh karena itu, para petani lebih mempertimbangkan ketersediaan unsur hara yang ada daripada jumlah total unsur hara yang ada pada tanah.
Dari penjelasan di atas, jawaban yang tepat adalah "Because the crop plants only need a few total supply of required nutrients to grow."
