Answers
Answer:
do not keep the tap open while brushing
bath with water in a tub as bathing in a shower waste 15-20 gallons of water in 10 minutes and do not overflow the field while farming as it may ruin the crops and waste water
1. Rainwater Harvesting:
Rainwater Harvesting (RWH) can be defined as a method by which the Rainwater is collected in tanks and reservoirs for future use. Unpredictable climatic conditions and depleting groundwater levels can be mitigated with Rainwater Harvesting. The best part about RWH is that it can be practiced in homes, offices, parks, etc.
2. Black Plastic and Organic Mulches:
Did you know that organic and black plastic mulches can save 25 percent in water requirements? Black Plastic or synthetic mulch not only reduces the water evaporation but also helps in controlling weeds and warms the soil, for an earlier crop. Organic mulches post decomposition provide nutrients to the soil and conserve moisture. Cover crops and Green Mulches can be used too.
3. Laser Leveling:
Unevenness of the soil surface impacts germination, stand and yield of crops. Farmers spend considerable time and resources in leveling their fields properly. However, traditional methods of leveling land are cumbersome, time-consuming as well as expensive. Laser land leveling can be defined as leveling the area within a certain degree of the desired slope using a guided laser beam throughout the field.
The benefits of Laser Land Levelling are:
Accurate distribution of water
Saving water
Conservation of soil nutrients
Precision Farming
Higher crop productivity
Fewer weed problems
Saving time, energy and resources
