Summary Introduction

To determine:

The amount of copper between 4 and 30 ppm eaten if 1000 kg of potatoes are consumed.

Introduction:

The nutrients are the atoms, molecules, elements or the compounds required by the living organisms for their growth and development. The plants obtain nutrients from the soil or synthesize through photosynthesis. On the basis of requirements, the nutrients are of two types, namely micronutrients and macronutrients. The micronutrients are usually required in parts per million, whereas the macronutrients are required in somewhat larger amounts.

Explanation of Solution

The copper is the micronutrient which is required in ppm for the growth of the plant. The conversion of 1000 kg of potatoes to milligrams is shown below:

1 kg =1,000,000 mg (milligrams)1mg/kg (milligrams per kilogram)=1 ppm1ppm=1 mg/kg4 ppm in copper=4 mg/kg

The amount of copper consumed by eating 1000 kg will be as follows:

The amount of potatoes consumed=1000 kgThe amount of copper=4 mg/kgThe amount of copper in 1000 kg=4 mg/kg×1000=4000 mg

30 ppm in copper=30 mg/kgThe amount of copper=30 mg/kgThe amount of copper in 1000 kg=30 mg/kg×1000=30,000 mg

Summary Introduction

To determine:

The amount of zinc between 15 and 100 ppm eaten if 1000 kg of potatoes are consumed.

Explanation of Solution

The zinc is the micronutrient which is required in ppm for the growth of the plant. The conversion of 1000 kg of potatoes to milligrams is shown below:

1 kg=1,000,000 mg1mg/kg=1 ppm1ppm=1 mg/kg15 ppm in zinc=15 mg/kg

The amount of zinc consumed by eating 1000 kg will be as follows:

The amount of potatoes consumed=1000 kgThe amount of zinc=15 mg/kgThe amount of zinc in 1000 kg=15 mg/kg×1000=15,000 mg

100 ppm in zinc=100 mg/kgThe amount of zinc=100 mg/kgThe amount of zinc in 1000 kg=100 mg/kg×1000=100,000 mg

Summary Introduction

To determine:

The amount of potassium between 0.5 to 6% eaten if 1000 kg (kilograms) of potatoes are consumed.

Introduction:

The nutrients are the atoms, molecules, elements or the compounds required by the living organisms for their growth and development. The plants obtain nutrients from the soil or synthesize through photosynthesis. On the basis of requirements, the nutrients are of two types, namely micronutrients and macronutrients.

Explanation of Solution

The potassium is the micronutrient which is required in larger amounts for the growth of the plant. The conversion of 1000 kg of potatoes to milligrams is shown below:

1 kg =1,000,000 mg 0.5% of 1000 kg potatoes =0.5100×1000The amount of potassium consumed=5 kg6% of 1000 kg potatoes =6100×1000

The amount of potassium consumed=60kg

Summary Introduction

To determine:

The amount of iron between 25 and 300 ppm eaten if 1000 kg of potatoes are consumed.

Explanation of Solution

The iron is the micronutrient which is required in ppm for the growth of the plant. The conversion of 1000 kg of potatoes to milligrams is shown below:

1 kg=1,000,000 mg 1mg/kg=1 ppm1ppm=1 mg/kg25 ppm in iron=25 mg/kg

The amount of iron consumed by eating 1000 kg will be as follows:

The amount of potatoes consumed=1000 kgThe amount of iron=25 mg/kgThe amount of iron in 1000 kg=25 mg/kg×1000=25,000 mg

300 ppm in iron=300 mg/kgThe amount of iron=300 mg/kgThe amount of iron in 1000 kg=300 mg/kg×1000=300,000 mg

Conclusion

The micronutrients are required in fewer amounts and the concentration is usually measured in ppm, whereas the macronutrients are required in larger amount and measured in percentage.
