Calculation for the management of water for Tree Crops (Sour Sop) during the drough season using the drip irrigration methods. Simple Pure Agro ( Grenada ) #Sour Sop Care in Drought
To calculate the number of water tanks needed for 1 acre of tree crops with 150 trees using drip irrigation at a rate of 1 gallon per hour per emitter, we need to consider the following:
Water requirement per tree per day:
- Each tree needs 1 gallon of water per hour.
- Assume the irrigation system runs for 8 hours per day.
- Therefore, each tree requires ( 1 \text{ gallon/hour} \times 8 \text{ hours/day} = 8 \text{ gallons/day} ).
Total water requirement for 150 trees per day:
- Total water requirement = ( 150 \text{ trees} \times 8 \text{ gallons/tree/day} = 1200 \text{ gallons/day} ).
Tank capacity:
- Assume the water tank capacity is 1,000 gallons (a common size for agricultural water tanks).
Number of tanks needed:
- Number of tanks = Total daily water requirement / Tank capacity.
- ( \text{Number of tanks} = \frac{1200 \text{ gallons/day}}{1000 \text{ gallons/tank}} = 1.2 \text{ tanks} ).
Therefore, you would need approximately 1.2 water tanks of 1,000 gallons capacity each to supply enough water for 1 acre of sour sop trees with 150 trees, running the irrigation system for 8 hours per day at a rate of 1 gallon per hour per emitter.
Since you can’t have a fraction of a tank, you would need to round up to ensure you have enough capacity. Thus, you would need 2 water tanks to meet the daily water requirements.
For A 5 acre plot Therefore, for a 5-acre plot, you would need 6 water tanks of 1,000 gallons capacity each to meet the daily water requirements for sour sop trees with 150 trees per acre, running the irrigation system for 8 hours per day at a rate of 1 gallon per hour per emitter.
The goal is 6000 gallons of water. The water storage and use during the drought period should be facilitated with a timer of to reduce the drip load to about 1 to 2 hours per day with mulch using the bagass method.
This will allow a 6000 gallons of water to last only 4 days at the 2 hours rate of flow leaking or dripping 2 gallons per hours.
Recommendation for Tanks:
4500 US GALLON for the farm with at least 3 of those tanks will hold 13,500 gallons of water – allow for a 2 hour drip to provide up to 12 days of watering capacity for the plants.
