Explanation:

Chemical fertilizers kill the micro-organisms in the soil. It is one of the advantages of organic fertilizers that they boost microbial activity in the soil. These microbes help in degenerating the complex compounds present in the organic fertilizers. Overuse of fertilizers is often a problem as excess nutrients are neither good for the overall composition of soil nor are they good for the plant Organic fertilizers would also have a problem of overuse, but it is a slow nutrient releasing material, so the nutrients will anyway take some time to get absorbed. The statement mentioned in the question stands incorrect. Organic fertilizers may take more time to release the nutrients as they need some microbial activity to gel them working. Chemical fertilizers get cracking instantly and release the essential nutrients into the soil. So statement 3 also stands incorrect.
