Quizz Flashcards
- Imagine you have been asked to manage compost application on a 60ha field, you are using 15tns/ha
What is the total amount of compost you need to apply?
So, 15 tons/ha * 60 ha = 900 tons of compost in total.
- Imagine you have been asked to manage compost application on a 60ha field, you are using 15tns/ha
How much material was needed to make this much compost?
900 tons
- Imagine you have been asked to manage compost application on a 60ha field, you are using 15tns/ha
Calculate the area of one quadrant.
Area = π r2
= π × 602
= 3600π
= 11309.733552923 meters2
- Imagine you have been asked to manage compost application on a 60ha field, you are using 15tns/ha
The compost has the following components of macronutrients; N 0.4%, P 0.2%, K 0.32%.
Calculate the amount of each macronutrient in each ton of compost.
For nitrogen (N):
0.4% of 1 ton = 0.004 tons = 4 kg
For phosphorus (P):
0.2% of 1 ton = 0.002 tons = 2 kg
For potassium (K):
0.32% of 1 ton = 0.0032 tons = 3.2 kg
So, in each ton of compost, you would have approximately:
- 4 kg of nitrogen
- 2 kg of phosphorus
- 3.2 kg of potassium
- You are asked to apply the organic fertilizer Nutrisoil, that has 0.49% N. Calculate how many liters N are in one container (1000L) of this product?
0.49% = 0.49 / 100 = 0.0049
0.0049 * 1000 = 4.9
So, 0.49% of 1000 is equal to 4.9L of Nutrisoil
- This field, pivot area is being given the amount of 40 mm per day.
Calculate the amount of water applied in m3 per hectare.
1 mm = 0.001 m
40 mm = 40 * 0.001 = 0.04 m
Area = 1 hectare = 10,000 m²
Volume = Area * Depth
Volume = 10,000 m² * 0.04 m
Volume = 400 m³
- The rain gauge in Matema collects 60mm in one day, the evaporation on that day was 6mm.
Calculate the balance of infiltered.
54
- There was rain the previous day, but you are scheduled to apply 40mm irrigation on the field.
Would you still irrigate? Justify your answer.
Yes and no depends on how much it raid if it’s enough no if it’s not no
