Vermicast is an organic ...Thanks for your comments. Vermicast is an organic material and thus it can improve soil quality and enhance crop performance. The only problem is that the amount that should be applied varies with soil type, crop, and climatic conditions. And very little scientific studies have been done on this aspect. For example, most of the trials conducted by students in the department revealed no increase in rice and corn yields upon application of vermicast. I think the rates used were low to cause any improvement in crop performance. Concerning indigenous microorganism (IMO)and other bio-organic preparations which are claimed to be effective biofertilizers, I think that some of them maybe effective at high rates (in several tons)but rigid scientific testing is urgently needed. To cite an example, in all natural soils, the activity of native microorganisms which are important for nutrient transformations and decomposition process can be enhanced by simple addition of organic materials. You do not need the tedious process of preparing IMO fertilizer using all sorts of food materials, sugars, etc. The important questions are: do these materials really improve soil quality and crop yield? If so what are the specific soil parameters and microorganism populations that are enahnced? At what rates of application can this be attained? Under what soil conditions are they effective? What crops are responsive?Victor B.

What is your opinion about it? Do you believe in what some sustainable agriculture advocates are saying about IMO that it is the future of sustainable agriculture? I hope for your scientific opinion. Many thanks. By the way, I find your blog excellent. It is a source of many important and many interesting ideas for me kasi malayo ako sa library. Keep it up.Anonymousnoreply@blogger.com
