Land is the levelled surface and other natural resources such as water, forests, minerals, etc. used for production of goods and services. Excessive use of chemical fertilisers or modern techniques of farming destroys land and all other natural resources. Land can be sustained through the following ways :
(i) Limited use of chemical fertilisers: Chemical fertilisers should be used in a limited number and only as the per the requirement. Excessive use of chemical fertilisers destroys the fertility of land.
(ii) Crop Rotation: Crops should be planted in such a way that land gets time of restore its fertility. Different nutrients are required with different lands; therefore planning of multiple cropping should be done in such a way that the land is also able to restore the lost nutrients.
(iii) Waste of chemical fertilisers: Waste of chemical fertilisers or pesticides should not be thrown in the water bodies of village as this will pollute the water.
(iv) Adequate use of ground water: Ground water should be adequately used so that there is minimum wastage of groundwater.
