Which of the following is/are correct? 1. Fertilizers are commercially available products that provide nitrogen, phosphorous and potassium to crops. 2. Fertilizer contains a large amount of organic matter which improves the water holding capacity of the soil. Select the answer using the code given below:

Fertilizers

• Fertilizers are commercially produced inorganic plant nutrients which supply nitrogen, phosphorus and potassium, such as urea, ammonium sulphate, superphosphate and NPK. Hence, statement 1 is correct.
• Fertilizers do not add humus or organic matter to the soil. Continuous use of fertilizers without organic manure reduces soil fertility and may cause water pollution. Hence, statement 2 is incorrect.

Manure

• Manure is an organic substance obtained from the decomposition of plant and animal wastes. It is rich in organic matter, improves the water holding capacity and the texture of the soil and increases the number of friendly microbes, but it is relatively poor in plant nutrients.
• Organic farming makes use of manure, vermicompost, bio-fertilizers and bio-pesticides in place of chemical fertilizers.
