Write down two advantages of fertilizer over manure
Advertisements
उत्तर
The advantages of fertiliser over manure are as follows:
1. Fertiliser is very rich in plant nutrients such as nitrogen, phosphorous, and potassium, whereas manure has a low nutrient content.
2. Fertiliser is soluble in water and hence readily absorbed by the crop plants, whereas nutrients in manure are absorbed very slowly as nutrients exist locked inside the organic compounds of humus.
